A cooling technique for fishes

A lot of people have taken upon the hobby of having fishes as pets. The aquariums range from the smallest to the most insane sizes. In the past, it used to be just fishes in the tank but now, you can bring in live corals in your aquariums. It’s like looking directly at the ocean which is just great, isn’t it?

However, proper care should also be given for them the fishes to continue living and giving joy to the people.  For starters, the temperature of the water inside the aquarium should be taken into consideration. Fishes will die in high-temperature waters for a long time. As the temperature in the water rises, the level of oxygen decreases and fishes won’t survive too long without oxygen. What can you do to prevent this from happening?

For starters, you can place your aquarium in a room where there’s an air conditioning chiller to help regulate the temperature. However, this proves to be more costly in long run which will be more impractical. Another alternative is the use of water cooled chillers or process chillers to help take out heat from the water in the tank. But if you do this, you need to understand that process cooling absorbs the heat from the water, takes in cool air from outside and releases the heat externally. It is best that you do not place your chillers in an enclosed place.

When you have aquarium chillers set up, make sure that you perform the proper chiller maintenance regularly to avoid any malfunctions of the machine.

Installing aquarium chillers can help you save the fishes.

The truth about chiller replacements

Industrial chillers are great equipments that bring in a lot of great benefits to industries. But they’re also expensive. In fact, they may be the most expensive equipment in other companies.  This is the reason why it is important to observe chiller maintenance and make sure that chillers aren’t abused. Chillers need to be taken cared of if industries want them to perform and serve them for a long period of time. But all good things must come to an end. However with industrial chillers, caution and thorough decision should be done before making a choice.

The biggest mistake in chiller usage is thinking that just because chillers, no matter how used, are still operating mean that they are still ok. Used chillers are still operating but not efficiently anymore and the overall cost for electricity charges may be more than the initial cost of actually buying a new one. However, one must think of all the factors before getting a replacement for used chillers.

A chiller’s condition is important and how old it already is. Changes have been made over the years and if the chiller started operating 10 years ago with a specific set of load, chances are they have changed as well. This may have caused an oversizing of the chiller. You can do a review of the load profile of your current building and re-evaluate the maximum cooling load that the chiller needs to meet. If it can’t be met, it’s a good sign for the chillers to be replaced but it still needs to be evaluated thoroughly.

How do you keep chiller efficiency high?

Since industrial chillers are greatly needed for certain industries, it is important to keep them effectively and efficiently performing at all times. Despite what type of industrial chiller is used, only one thing remains certain: regular maintenance for chillers should be observed.
Chiller maintenance is an important part of a chiller’s life. In order to keep your chiller’s efficiency high, you have to take time to check it regularly. You need to check the tubes, the controls, refrigerant charge optimization and regular oil changes.

In cleaning the tubes, you need to inspect the heat exchanger tubes and flow devices. A tube’s condition will determine how to clean the tubes in the future and it also tells you if the water used is good for the tubes or not. Cleaning the tubes help greatly in the efficiency of used chillers.

Refrigerant charge is important in optimizing used chillers’ performance and energy efficiency. Too much of it can cause a carryover which can cause a reduced capacity and excess power consumption among other damages. Not enough supply can also lead to trouble. This is why it is important for the refrigerant charge to be just enough.

Oil is also critical in chiller efficiency. It is important to do an oil analysis once a year. You should also do oil and filter change after a year. Particles in the oil tell you what type of wear problem is happening inside the chiller. The oil level must also be observed closely.

Like any other equipments, regular checkups and maintenance is needed to keep chiller efficiency as high as possible.

What are the types of condensers?

We all know that industrial chillers are beneficial and help industries cool the necessary equipments. We all know that they are high-priced items and proper chiller maintenance should be observed if you posses one to maximize its life span. Otherwise, you’re risking of cutting off its efficiency and eventually its life. It is also important to know all that we can about chillers to better equip ourselves.

While other articles are talking about the different types of chillers: from air cooled chillers to water cooled chillers, this article talks about just one part of both types of chiller. Before getting to this particular part, the refrigerant must travel across different tubes and mechanisms that aid in the whole process. After which it ends up in this special place: the condenser.

The condenser is where the refrigerant gives off heat energy into either a water source or air. Most chillers use air cooled or water cooled condensers to aid with this process:

•    Air cooled condenser
An air cooled condenser is a copper tubing coil that has aluminum fins and condenser fans. They are an essential part of a chiller because this is where the refrigerant throws out heat directly into the air.

•    Water cooled condenser
Water cooled condensers have shell and tubes for heat exchangers that have condenser water running through them. The condenser water flow must have the same flow velocity as that of the evaporator.

Industrial chillers or any type of chillers have condensers. They may differ in the process and design but they were created for one purpose only: to remove heat and give that cooling effect needed.

How to buy chillers and what to consider

Going shopping for chillers is not as easy as it looks. You need to be in the know so you can make the right choice and not end up with something that can only complicate things instead of helping.

When you’re out buying your very first industrial chiller, there are a few things to consider such as materials, components, efficiency and operation. By taking them into consideration, you are assured that you’re not only getting a good chiller but you’re also getting your money’s worth. Let’s take them one by one.

The first factor you need to check out in buying process chillers is the materials used in the production. Stainless steel is the best choice for chillers nowadays.

To avoid future trouble with parts, make sure that the components of your chosen chiller whether it be a water cooled chiller or an air cooled chiller are standard components that are available in other major wholesalers and not just manufacturers.

Of course, industrial chillers are of no use if they can’t deliver efficiency. You have to compare the money spent on the chiller and the money you can save on energy over a long period of time.

Chillers must be user-friendly. The controls must be easy to read and easy to use. This is essential especially to first-time users. Any complications might lead to misuse and destruction of the chiller.

Choose a chiller that have components place for easy access for inspection and replacements if necessary. Small-compact units aren’t that advisable because chiller maintenance tends to be a hassle, having to take the chiller apart for inspection or any other service.

Chillers come with a warranty of up to 5 years for new ones. Check out for how long the warranty is for your chosen chiller before you make it to the cashier.

How process chillers can save water

How do industrial chillers save water? Well, with global warming becoming more and more apparent, a little effort in saving our environment goes a very long way. One natural resource in particular that we’re nearly running out of is water. If we don’t take care of it, we’ll lose it. Thus, saving water is of primary importance right now.

A large amount of water is used in different industrial purposes all over the world. Because of this and the desperate pleas for our environment’s survival, industries are now looking for ways to cut back the waste.

An example of an industry that uses a lot of water is a hospital. Sterilization is a key aspect in a hospital’s day to day activities. Instruments and equipments must be sterilized to ensure safety and health. However, large amounts of water are needed to cool the sterilizer and these amounts usually end up in waste after used.

Instead of wasting too much water on that, you can use process chillers. These chillers take hot water from the condensers and vacuum pump. They then cool it down and pump it right back to the sterilizer. Process chillers also help keep the cycling time of sterilizers constant regardless of different weather conditions. If your chillers have large buffer tanks, there are no negative effects even if there’s an extreme change in temperature. Switching to industrial chillers prove to save a lot of money and water at the same time. With the right chiller maintenance, your chillers will last longer than you thought.

Chiller Efficiency and Maintenance

If your company owns one of those industrial chillers to help maintain various equipments that may be damaged from too much heat, then you’d probably know that chiller maintenance don’t come easy.

A chiller can only be beneficial if its efficiency is at its maximum or remain to be unaffected despite several factors.

A chiller’ efficiency is measured by the amount of energy it needs or it takes to produce a ton of cooling and is usually expressed as kw/ton. All types of chillers including air cooled chillers and water cooled chillers have certain efficiency established before being released out in the market. However, there are a lot of factors that can affect it which can result to poor efficiency and higher operating costs.

An industrial chiller can have an operator to better keep track of the activities. The operators are known by a few titles: Stationary Engineer, HVAC engineer or service technician. Nevertheless, they perform the same job: they watch over the chillers. Chiller operation includes collecting and logging data from different estimates and controls the meters near or on the chiller. There are also service contractors whose expertise is the equipment repair. They are the ones you must call when you need major repairs.

There are three types of chiller maintenance:

Water chemistry – keeps the proper balance and minimizes the effects of corrosion, and debris fouling.Mechanical Maintenance – includes adequate liquid refrigerant, proper lubrication and a series of oil levels and pump curve tests.Operational Procedures – includes calibration of gauges and meters, oil analysis and other different tests that checks the operation process.

Chillers must be maintained and kept well for a longer lifespan. They don’t come cheap so taking care of them is worth the extra years they give as service before they break down.

Taking Care of You Chiller Unit

If you own a water cooled chiller or any other chiller unit, then for sure you want it to run at its best. In keeping up with your chiller maintenance you will extend the life of your chiller and will also help keep the amount of money to run the unit down. Not having the right maintenance can have its consequences. The machine can start to rust sooner than you expect and you’ll end up spending more money repairing it than having it checked out every few months.

Keeping a daily log on how the recirculating chiller is running is one thing you can do to make sure that the unit is running smoothly. In the long run, doing this can also make you save money because it gives you a basis of how the chiller normally works and this is also good because if something starts to go wrong with the machine, then you would know about it before the chiller breaks down. This is especially important if you purchased a used chiller.

Something else you can do to ensure that your industrial chiller will be running its best is to make sure that all the wiring is efficient and up to date. Old wiring can cause your electricity bill to surge and giving attention to this can also confirm that there are no kinks in the wiring and that the wires are not all tangled up. Purchasing a chiller that’s just the right size can keep your cost down as well. It’s a common thing for people to buy the wrong type of chiller and this can cause the chiller’s life to shorten.

Taking note of simple things like this can help you in maintaining a good chiller. J5NPHMMXKQBD

Chiller Threats

In big industries, chillers use up almost fifty percent of its entire electricity consumption, making them high-maintenance equipment. Because of this, proper maintenance for industrial chillers or any chiller for that matter should be a priority and should be something that is consistently being done.

Poor operating practices cuts down the chiller’s life as well as decreasing its efficiency. These practices include but are not limited to trying to force a chiller to do something that it wasn’t designed to do. You have to understand what your chillers are meant to do. You have to get to know your process chillers or other types of chillers. An important note with these practices is that the consequences are unnoticeable at first. Chillers continue to act normal but time will come when it gives in and breaks down faster than it should.
Chiller maintenance shouldn’t be taken lightly especially for equipment such as this. Good maintenance is essential in keeping chillers in top condition. A brand new air cooled chiller can carry a particular amount of load. Over time, that load decreases gradually. However, if maintenance is ignored then that decrease will happen faster than it should.

Chillers have cooling towers that assist in their efficient operation. They allow chillers to operate efficiently to their maximum potential. It is essential that these cooling towers are kept in top shape because a slight decrease in its performance will have a major impact on the chillers.

A chiller should be properly sized for an efficient operation. For example you have a new air conditioning chiller and the size of the load is sufficient for it to run smoothly. However, changes are made such as new windows or new lighting systems. This decreases the load for chillers and as a result, decreases its efficiency. You have to keep track of this and make sure that the balance is maintained.

Chillers have helped humanity in more ways than one especially in big industries. Therefore keeping them safe and treating them well is just right.

Chiller Maintenance

Chiller maintenance is an essential and critical part of having and owning a chiller. Chillers need special attention and care to fully maximize their performance and efficiency longer. They don’t come cheap thus should be kept in good condition. There are specific handling techniques in taking care of used chillers. Here are some of them:

- Keep a daily log that consists of the different operating characteristics of your chiller. This gives you an overview of its dxlay to day performance.
- Before the cooling season, check the starter and controls of your chiller.
- Make sure the interior of you chiller is clean and in proper condition:
• No litter, dirt or any kind of debris.
• All the wiring connections are tight.
• All linkages move freely.
• Overloads are set correctly and are functional.
- Double check to see if the safeties and controls work. They all should work.
- Do a careful and thorough inspection of the compressors every so often.
• Check the compressor oil level and filter. Change them as often as the manufacturer’s guidelines say so.
• Have the oil sample examined to check for destructive acids and corrosive materials.
- Make sure the crankcase heaters are functioning correctly.
- Check if the water cooled chillers have full refrigerant charge by keeping a close eye on operating pressures and temperatures.
- For air conditioning chillers, clean the condenser coils and make sure that the condenser fans are working.
- For bigger chillers such as industrial or process chillers, performing an eddy current tube helps prevent major chiller breakdowns. This is a process wherein a trained technician runs electricity on each tube and studies the flow of current.

Following the above mentioned chiller maintenance tips help a great deal in preserving and lengthening the lifespan of your chillers.

Choosing the Right Company to Repair Your Chiller

It’s normal for appliances to get serviced from time to time. There are just some things that need to be taken into consideration before settling on a company that can do the service for you. Refrigeration units and other similar appliances like water cooled chillers are not easy to fix and should be handled meticulously, which means that trying to do the repairs on your own is not the best option.

Chillers such as
air cooled chillers, recirculating chillers and others types are very complicated and you need a certified specialist to get the job done quickly and efficiently. The last thing you want to do is have your own business down longer that it needs to be. If you try to repair the unit on your own because you’re trying to save money, don’t bother. You may end up having to spend more in the end. Finding a company that can get the job done right at an affordable price is easy. The first thing you need to look for is a company that has several experiences in chiller maintenance and one that is familiar with your unit.

Thinking of a company that charges low prices for servicing may not always be your best option, since they may not be familiar with your type of unit and can take twice as long to fix the problem. If the company is familiar with the brand of your industrial chiller, they can easily diagnose the problem and have your unit up and running in no time.

Hiring a certified company to repair your unit can have its benefits. Some offer a warranty and other “perks” which is important for you. Being careful about what kind of company you hire to fix your valuable assets is something more essential than money. By doing this, you can save more in the long run.

Steps to Prolong A Chiller’s Duration

If you own an air or water cooled chiller, always make sure you keep it maintained regularly, otherwise its performance can gradually degrade. This can result in temperature variations that can affect productivity and quality. Chillers are supposed to provide heat removal and cool down the temperature of temperature-sensitive equipment. Air cooled water chillers are not only for industrial use. Some people have them at home for their aquariums.

Most chillers don't require much attention to keep it working effectively, although like any other machinery or appliance, it needs regular check-up and cleaning. Contacting the dealer can help you with regular chiller maintenance.

There are three basic steps to ensuring that your chiller gives you optimum performance. The first one is to inspect and clean the air filter. Air cooled chillers rely on a steady flow of air over the condenser coils and a filter is used to cleanse the incoming air and prevent dust. A dirty filter restricts the flow of the chiller, which is needed for it to perform properly.

The second step is to check heat transfer fluid levels. Cooling fluid levels can be determined with simple visual inspections. The fluid is the lifeblood of the cooling system and without it, heat removal cannot occur. Checking the heat transfer fluid's properties is the final thing to do. Dirt and other particles can make its way into the industrial chiller, causing damage to the pump and clog other parts, which is why this step is just as important as the first. Not cleaning the parts thoroughly can impair chiller operation. Simply follow these three steps to ensure optimum performance from your chiller.

Chillers are Significant for Aquariums

When it comes to keeping your aquarium residents happy and healthy, having the right temperature is important. A sudden change in temperature can actually make your aquatic pets stressed, thus increasing the chance of them dying. This happens especially to the inhabitants of reef aquariums. This type of aquarium needs lots of special equipment, such as lighting, water pumps and an air cooled water chiller or water cooled chiller.

The cooled chiller is needed to produce the right water temperature, and without it the water can be so warm to a point where it can no longer hold enough oxygen to sustain the inhabitants. If you need a chiller for your aquarium at home, install it as early as possible. If the budget for a new chiller isn't enough, a used chiller that is in good condition would do just fine. Just keep in mind that they need adequate space and ventilation, and also remember to avoid putting the chiller in an enclosed aquarium stand since it can cause overheating of both the chiller and the aquarium.

When choosing a chiller, make an estimate of the maximum temperature your setup may produce as well as considering the temperature requirements of your aquarium inhabitants. There are different types of chillers available all over the market, such as in-line chillers, thermoelectric chillers and drop-in chillers to name a few. Thermoelectric chillers are the ones intended for the use of small aquariums. In-line chillers are those for large systems that are used primarily with saltwater reef setups, while drop-in chillers have a probe that is placed directly into filters. Whatever type or brand you choose to use, the most important thing is regular chiller maintenance to prolong its existence.

Choosing the Type of Chiller for Your Business


When purchasing air cooled water chillers or any industrial chiller for that matter, there are things that we should all learn before buying them. First things first, we should of course know how they operate. Not all chillers operate the same. Knowing how they work will help us in deciding which chiller is the best for us and our businesses.

Chillers usually have six parts. The condenser, pipes, refrigerant, pumps, refrigeration equipment and a coolant expansion reservoir. Depending on the size of the unit, cooling water can be up to 20 degrees Celsius and can circulate up to four hundred tons of water. Whether you need a small one or a large one for your industrial equipment, there will always be a unit to meet your needs.

If you are still starting your business and the budget is a bit tight, purchasing used chillers that are in good condition can help you save. There are various companies that can help you with chiller maintenance so the unit's lifespan will be prolonged.

There are many different types of chillers to choose from, that oftentimes it can get a bit confusing. There are air cooled chillers, water cooled chillers and other types that are used as oil coolers. Some questions that a novice should ask is what the maximum and minimum heat loads will be. They should also ask whether the system will be able to reject the heat to the outdoors and what the available power supply is.

The answers to the questions are important in order for the chiller to have optimum performance. Contacting the local distributor of your choice can also help in leading you to the right direction.
