Introducing Copeland's Inverter Swing Rotary Compressor
Designed to deliver competitive performance for residential heat pump and AC applications.
As the residential HVAC sector migrates from fossil-fuel-burning furnaces to electric heat pumps, modulating compressor technologies will be needed to meet higher efficiency and capacity targets. Copeland’s inverter swing rotary compressor answers the call, offering competitive performance in the 1.5–5-ton residential product range.

Unmatched service and customer support network
Innovative swing rotary design
Copeland inverter swing rotary compressors integrate the vane and roller into a single unit, as shown in the figure. This design reduces wear of the vanes and rollers by eliminating the need for springs and minimizes leakage from the intake and discharge chambers. This is especially effective at low rotation speeds, which occur in part-load conditions .
The piston, which integrates vane and roller, oscillates and a new component called a swing bushing supports it. As long as the piston is in motion, it and the swing bushing are constantly sliding against each other. In the figure, the swing bushing and piston appear to be in surface contact, but in reality, they are in linear contact at the base of the vane.
The inverter swing rotary compressor and other compressor technologies from Copeland provide North American OEMs with a range of compressor solutions.
