Reliable and quiet operation
Reliability
The use of the Scroll compressors ensures excellent reliability. Versus a reciprocating compressor, the Scroll has the following advantages.
- 64 % fewer parts.
- The Scroll compressor generates significantly less vibration therefore reducing the risk of discharge line failure.
Performance
The absence of dead volume at the end of the compression cycle ensures better performance. The absence of fragile moving parts, such as springs and valves, also means that this performance is maintained with time.
Part load performance
The Scroll compressor always operates at full load. The chiller capacity is a function of the number of compressors running. In this way the power factor is maintained at a high level even at low loads.
Low sound level
The Scroll compressor is significantly less noisy and generates less vibration than a reciprocating compressor. In addition, on sites where the noise level is critical, the compressors can be fitted with an optional sound attenuating enclosure.
Reduced maintenance
The Scroll compressor does not require routine maintenance due to the absence of fragile parts, such as springs and valves which require regular replacement.
Other standard features
- Thermal insulation of the water connections, and of the evaporator.
- Loss of water flow protection provided by a differential pressostat.
- Operation up to + 40°C external temperature.
- Shipped with rubber pads.
- Centrifugal fans which allow to obtain a static pressure up to 500 Pa.
- A resistance heater placed on the evaporator to avoid freeze-up risk. The heater is energized only if the external temperature is below + 2°C.
- Pressure transducers to obtain an optimal control of the fans and to allow to display the low and high refrigerant pressure.
- Modem connection.
- Electrical panel IP 55.
