Semi-hermetic refrigeration compressor DHG series

twin-screwvariable-speedfor industrial refrigeration

Duplex compressors are the simplest kind of parallel connection between two compressors. Particularly efficient capacity regulation is possible here by switching individual compressors on and off. Other capacity levels are possible as required with additional capacity regulation (shutting cylinders down). The Pluscom compressors also offer the possibility of fully variable speed control of one compressor with a directly mounted ready connected frequency converter (option). Special features: - Erected next to each other - Each compressor has its own suction connection (shut-off valve) - Emergency operation with one compressor possible in the event of a fault
