ECOLINE TANDEM P - 44FESP-10(P)
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.
