Double Stage Compressors – SRS Serie
Again SRMTec is writing history by the introduction of the semi-hermetic screw compressor suitable for Ammonia supporting the conversion from environment harming substances like CFC’s to Natural Refrigerants.
Equipped with the i-profile and a permanent magnet motor these compressors make no compromises on energy efficiency. The aluminium windings of the motor take no chances of deterioration compared to insulated copper windings.
Without shaft-seal this technically permanent leak-proof solution is perfectly suited for applications in or close to residential areas where apprehension against Ammonia might prevail. That makes this compressor predestined for commercial process cooling or comfort cooling/heating.
Double Stage Compressors:
This unique solution is perfectly suited for applications with very low evaporation temperatures where compactness is needed, like on ships with limited space to drive a shock or blast freezer.
SRS semi-hermetic double-stage Screw Compressors include 3 series (SRS 1008, 1210 and 1612) totaling 6 models with a displacement of 141 – 652 m3/h @ 2960 rpm. The application window is optimized for low temperature applications like freezers and blast coolers. Whereas all major refrigerants can be used, our compressors are optimized for the natural and environment-friendly refrigerants such as Ammonia R717.
The semi-hermetic construction results in a permanent technical leak-proof solution without a shaft seal. The double-stage construction allows the design of very compact packages and is perfect for stand-alone applications where no side load of a traditional booster system is required.
The use of frequency inverters, a permanent magnet synchronous motor and optimized Vi ensure high efficient operation.
