Even when your chiller is inspected and maintained regularly, its performance can degrade or deteriorate over time. Pumps can fail, process lines can clog, refrigerant can leak, and any number of problems associated with component aging or changing environmental conditions can occur. We list some reasons for common chiller problems for you reference.
1. Chiller does not power up
- Improper line voltage or loose connection
- Incorrect phase connection (three-phase units)
- Blown circuit breaker or fuse
- Power switch in “off” position
2. No pumping or insufficient fluid flow
- Improper or fluctuating line voltage
- Insufficient fluid in reservoir
- Pinched or restricted process line
- Close or partially closed process valve
- Coolant fluid unsuitable for temperature requirements
- Blocked fluid filter
- Process piping too small
- Process restriction
- Pump failure
3. No cooling or insufficient cooling
- Improper or fluctuating line voltage
- Clogged air filter or condenser
- Coolant fluid unsuitable for temperature requirements
- Heat transfer properties of the coolant fluid have deteriorated
- Refrigerant leak
- High ambient temperature
- Evaporator iced up
