Copeland Launches KF Variable-Speed Scroll Compressor with EV4 Variable Frequency Drive Platform

ST. LOUIS (Jan. 12, 2026) — Copeland, a global leader in compression technologies and controls solutions, today announced the launch of the KF variable-speed scroll compressor with EV4 variable frequency drive platform in North America. The KF is Copeland’s premium variable-speed scroll compressor for the 1.5- to 5-ton North American residential market, designed for premium comfort — especially in cold climates.

Energy costs are outpacing inflation in the US with prices up 5% compared to a year ago and roughly 30% since 2021, according to the Consumer Price Index. This is pushing consumers to find ways to reduce their energy consumption.  As these factors drive evolution in the HVAC industry, the residential segment is transitioning to more energy-efficient, eco-friendly equipment. Heat pumps help decarbonize heating by replacing or reducing the operating time of fossil fuel-burning furnaces or inefficient electric furnaces. However, maintaining comfort in cold climates remains a challenge, and heat pump technologies are advancing to provide the required capacity in low-ambient conditions. Variable-capacity modulation compressor technologies — including variable-speed with its ability to overspeed and provide incremental capacity modulation — have proven to deliver the capacity needed to overcome comfort limitations and achieve required efficiency targets.

Residential heat pumps must also comply with federal refrigerant regulations and use compression technology optimized for refrigerants with a global warming potential (GWP) below 700. The Copeland KF variable-speed scroll compressor platform is optimized for the low-GWP A2L refrigerant R-454B and is engineered to meet future efficiency standards—supporting both regulatory compliance and peak system performance.

Copeland’s KF variable-speed scroll compressor platform addresses key HVAC market needs by delivering leading performance, design flexibility and robust support. Its 10:1 turndown ratio provides strong efficiency across a wide range of operating conditions. With a capacity range of 1.5 to 5 tons and potential for advanced features like vapor injection, it supports next-generation designs. The platform’s small footprint, seamless pairing with the Copeland EV4 variable frequency drive platform and ability to simplify original equipment manufacturer (OEM) controls and system design make it a versatile solution for both mid-tier and premium-tier systems.

The KF platform will be produced in North America, ensuring regional sourcing and supply chain assurance for OEMs. Backed by Copeland’s extensive North American service and support network, it also offers proven reliability, application engineering expertise, rigorous testing and comprehensive design support.

“The KF variable-speed scroll platform represents Copeland’s commitments to innovation and continued investments in next-generation variable-speed scroll technologies,” said Brandy Powell, vice president/general manager, residential and light commercial HVAC for Copeland. “It was designed from the ground up for variable-speed applications and is anchored by the proven Copeland scroll platform. By combining advanced engineering with intelligent design, this product delivers premier performance across residential applications and sets a new benchmark for excellence in HVAC solutions with its patented technologies.”

This product will be available for production during the second half of 2026; it will be demonstrated in Booth #C3607 at the 2026 AHR Expo in February. To learn more about Copeland’s KF variable-speed scroll compressor and EV4 variable frequency drive platforms, please visit Copeland.com.
