Features
HIGH EFFICIENCY, LOW VIBRATION
Scroll compressors have become renowned for their high levels of efficiency, low noise and low vibration. The scroll compressors incorporate anumber of unique features. These include compressor motors cooled by the discharge gases and the placement of the oil reservoir on the high-pressure side, for improved efficiency and oil supply.
COMPRESSOR PROTECTION
Crankcase heaters are fitted to all compressors to prevent liquid accumulation
damaging compressors on start-up while the suction line accumulators prevent
liquid refrigerant from entering the compressor and causing damage.
In addition, compressors are protected from low voltage, voltage fluctuation,
phase imbalance, and failure of related components through the use of:
• mercury overcurrent relays
• a dual pressure switch
• a timer relay
• a reverse phase protection relay
• a discharge gas thermostat
• indoor and outdoor fan overcurrent relay
• compressor crankcase heaters
