Scroll Condensing Unit

A scroll compressor is a specially designed compressor that works in a circular motion, as opposed to up-and-down piston action. Scroll compressors are becoming more popular for use in HVAC systems, as they are more reliable and efficient than reciprocating types.A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger) and as a vacuum pump.
