2nd generation 2-stage Tandem

Tandem compressors are the simplest way of connecting two compressors in parallel. Turning on and shutting off one compressor allows for a particularly effective graduation of output. Particularly for applications with load fluctuations, this allows for cost-effective and energy-efficient operation under full- and part-load with all conventional refrigerants.
