With the HFC phasedown and the transition to natural refrigerants, the range of the HGX56 CO₂ T transcritical compressor is designed for demanding conditions and uses the natural refrigerant R-744, the company said. The six-cylinder capacity allows for a wider spread and the faster uptake of large CO₂ heat pumps and industrial refrigeration systems. Additional benefits of the increased capacity — up to 135 kW for cooling and 360 kW for heating —include greater efficiency and reliability, along with low noise and vibration, a compact and lightweight design, and a minimal oil carry-over rate, the company said.

The HGX56 is an alternative to compressors that use HFC or HFO refrigerants or ammonia, and provides optimal performance at full and partial loads, Danfoss said.

“The Bock HGX56 CO₂ T compressor provides an ideal solution for industrial and commercial customers looking to increase efficiency at lower cost, and reduces system complexity,” said Vikas Anand, vice president of Danfoss Climate Solutions sales in North America. “We are looking forward to helping our industrial and commercial customers make the transition to natural refrigerants while raising the bar on efficiency and the ability to prolong the service life of the application via fully serviceable design.”
