The new vibration absorbers are suitable for CO2 and hydrocarbon systems.
The valves are made without brazing or welding between the valve body and connections, reducing leak points.
Biaggini’s system is one of the first of its kind to use CO2 as the refrigerant in dual-duty air conditioning/heating system, the company said.
The solenoid valves are for 120 and 140bar pressure; the safety valve for 150bar pressure.
The component manufacturer has bought an Italian company called Pego.
At China Refrigeration 2015, which gathered over 60,000 visitors and 1,000 exhibitors from across the world, CO2 products were showcased for a variety of applications for both heating and refrigeration. For commercial refrigeration applications, R744.com partners such as Carrier, CAREL, Panasonic, Dorin, SANDEN and Castel, as well as others demonstrated their CO2 know-how.
