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.
