Saginomiya, a Japanese manufacturer of components and controls for HVAC&R systems, has joined the world’s leading CO2 (R744) stakeholders as a bronze partner of the R744.com marketplace.
For more than 20 years, Saginomiya has developed components for CO2-based heat pump water heaters in Japan.
The company has expanded its product portfolio to include automatic controls that help ensure the efficient operation of subcritical and transcritical CO2 refrigeration systems under extremely high pressures.
Products include pressure controls, pressure sensors and expansion valves like its JKV motor-operated valves.
Saginomiya recently showcased its new CKB CO2 pressure controls at the International Air-Conditioning, Heating, Refrigeration Exposition (AHR Expo) in Atlanta, Georgia (U.S.). According to the manufacturer, the CKB pressure controls are suitable for low- and medium-temperature refrigeration systems that use ultra-high-pressure CO2 and offer high accuracy and high durability.
Also on display at the AHR Expo were Saginomya’s CCB pressure controls, HPV solenoid valves and UKV0J, JKV electronic expansion valves – all designed for CO2 systems.
Saginomiya says its CO2 technology is designed to meet the increasing demand for environmentally friendly systems that use natural refrigerants.
Established in Tokyo in 1940 as the Bellows Research Institute, the company became Saginomiya in 1948 and now has production facilities in Japan, China, Thailand and Poland.
While known predominantly for its work in air-conditioning and refrigeration, Saginomiya also manufactures goods for the heavy electric, semiconductor, transportation and medical industries.
