Two stage semi-hermetic refrigeration compressor
06CC series Carlyle Compressors

In high-ambient environments, whether ongoing or during peak demand seasons, Carlyle Compound Cooling compressors offer serious performance advantages over single-stage compressors. Unlike single-stage compressors, Carlyle Compound Cooling uses an economizer cycle to deliver higher capacities and efficiencies for the same displacement. The first stage utilizes four cylinders and always operates at a low compression ratio. Two additional cylinders act as the high stage, completing the compression cycle at discharge temperatures much lower than a single-stage compressor. Lower discharge temperatures result in increased reliability.

The result is two complete cycles operating at low compression ratios. That means lower internal losses and higher efficiencies than single-stage units of the same size. And since each unit operates at such a steady capacity, your systems will cycle on and off reliably, not
