ECOLINE Tandem P series

ECOLINE Tandem P series

On the notepad 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. The 4- and 6-cylinder models can also be equipped with capacity control systems (cylinder cutoff), allowing them to run with up to four or six levels of output. Particularly for applications with high load fluctuations, this allows for cost-effective and energy-efficient operation under full- and part-load with all conventional refrigerants.
