Bitzer has announced it has modified all models of its two-stage reciprocating compressors to enable them to run with R-448A and R-449A refrigerant. The refrigerants have global warming potentials (GWPs) of 1,386 and 1,397 respectively.
The high-efficiency, variable-speed CSV Series screw compressor features an integrated frequency inverter. The inverter is cooled by refrigerant and includes automatic, infinitely variable-speed control to ensure the right temperature profile at the lowest possible power consumption.
Bitzer U.S. Inc. launched new products at the Refrigeration Engineers Technicians Association (RETA) show in San Antonio this past November. The company announced it was assembling ammonia packages ranging from simple motor-compressor combinations on rails up to complete rotary screw compressor packages.
A focused product line of residential Copeland Scroll™ and reciprocating compressors bundled with high-quality components meet the growing need for aftermarket replacements, the company said. It is designed to provide contractors with everything needed to reliably replace a compressor.
