Meet the all-new KF variable-speed scroll compressor
Copeland’s groundbreaking KF variable-speed scroll compressor and EV4 variable frequency drive redefine residential HVAC performance from the inside out.
A revolution in variable-capacity performance
As the residential HVAC sector accelerates heat pump adoption and sets higher cooling efficiency standards, Copeland’s innovative KF variable-speed scroll and EV4 variable frequency drive answers the call. Offering premium variable-capacity performance in the 1.5–5-ton residential product range, the KF helps to drive decarbonization, enhance comfort and increase efficiency in the most demanding applications.
Top performance
The Copeland KF variable-speed compressor platform sets new benchmarks for reliability, capacity and efficiency — even in the most demanding heat pump and air conditioning applications..
Innovation from the ground up
The KF reflects a ground-up, redesigned approach to variable-speed compression innovation, built upon the legendary DNA of the industry’s most reliable and widely adopted Copeland scroll platform.
Simplicity and design flexibility
The optimized pairing of the Copeland EV4 variable frequency drive and KF compressor delivers seamless configurability to streamline OEM controls and system design. Innovative oil management lowers applied costs while enhancing stability.
Trialed and tested for reliability
The cutting-edge KF variable-speed scroll compressor is held to the same torture-tested reliability standards as every compressor that bears the Copeland name. Like every scroll, the KF is designed to wear-in, not wear out.
North American service and support network
Copeland offers an unmatched service and customer support network, combining manufacturing, distribution, and aftermarket resources.
Provides up to 7% SEER2 cooling efficiency gains compared to competitive models.
Heating-optimized design boosts capacity in low-ambient conditions, meeting the DOE’s cold climate heat pump (CCHP) requirements for 100% capacity at 5 °F.
Over 30 patents filed through the design process, reflecting ground-up approach to innovation.
The KF has been tested for over 20,000 hours in real-world field trials and more than 200,000 hours of lab testing to validate performance.
