This series includes semi-hermetic piston compressors with two, three and eight cylinders for normal and low temperature cooling applications as well as for use in high temperature process cooling or air conditioning. The main difference between Discus and conventional piston devices lies in the design of the valve plate. The Discus valve plate allows gas to enter the cylinder with minimal heat absorption whilst the cavities on the intake side evenly guide the gas and keep losses to a minimum. These effects have the following benefits:
- Top class cooling performance due to the lack of dead space
- Up to 10% efficiency increase compared to conventional “cost-effective” suction tongue compressors
- Lower operating costs for the end user
The Discus series ranges from 5 to 60 hp with a displacement of 16.8 to 181 m3/h. These compressors are approved for use with refrigerants R407A/F/C, R448A/R449A, R404A, R134a, R450A and R513A. All Discus compressors are designed for maximum performance and reliability:
- The “puck” shaped Discus valve integrated into the valve plate provides maximum power in all operation conditions. Displacement pumps with fast flowing oil guarantee a high oil supply pressure to ensure good lubrication and bearing cooling.
- PTFE coated bearings for especially low friction and effectives protection during start-up
- Electronic motor protection module
- Two motor sizes available for each displacement capacity. The smaller motor is suitable for all refrigeration applications, whereas the larger design can be used for air conditioning and frequency inverter applications
Features
- The highest efficiency on the market, regardless of refrigerant and operation conditions
- Integrated oil pump and the best reliability due to the user of the OPS2 electronic oil pressure switch
- Two motor sizes depending on cubic capacity, optimised for different application
- Additional areas of ...
- The highest efficiency on the market, regardless of refrigerant and operation conditions
- Integrated oil pump and the best reliability due to the user of the OPS2 electronic oil pressure switch
- Two motor sizes depending on cubic capacity, optimised for different application
- Additional areas of use: a single model can be used for both normal and low temperature cooling with an extremely low condensation temperature threshold of just +5 °C
- Power regulation by blocking off the flow of intake gas or using frequency converters from 25 to 60 Hz
- Universal compressor for different refrigerants – one model that allows the use of many different standard refrigerants
- 2 and 3-cylinder models can be optionally used with the additional Demand Cooling function in order to enable use in low temperature applications without excess heat limitations for the new refrigerants R407A/F, R448A and R449A
