1. Do chillers need regular refrigerant replacement?

No. Chillers do not require routine refrigerant replacement. As long as the system stays sealed, the refrigerant remains usable for the entire lifespan of the chiller.

2. When should refrigerant be replaced?

Refrigerant should be replaced only when it becomes contaminated by air, moisture, or impurities, or when a major leak leaves very little refrigerant remaining in the system.

3. What are the signs of low refrigerant in a chiller?

Signs of low refrigerant include reduced cooling performance, higher-than-normal outlet temperatures, long or frequent compressor operation, frost on the evaporator or suction line, and system alarms related to pressure.

4. What happens if a chiller runs with low refrigerant?

A chiller running with low refrigerant will cool poorly and place extra stress on the compressor. Continued operation can lead to overheating, reduced efficiency, damage to internal components, and possible compressor failure.
