Parker-Sporlan-TEVUSA: Parker Hannifin has released a range of Sporlan products designed for next-generation low-GWP refrigerants.

The products are said to address systems designed for CO2, hydrocarbon, HFO and lower-GWP HFC refrigerants.

New products for transcritical CO2 systems include 140 bar MRP-rated gas cooler/flash gas bypass valves, and filter-driers. Products for subcritical CO2 applications include electric expansion and pressure regulating valves, solenoid valves, filter-driers, check valves, and sight glass moisture indicators rated up to 70 bar MRP.

ATEX compliant thermostatic expansion valves, solenoid valves, filter-driers, and sightglass moisture indicators are available for use with A2L and A3 refrigerants, including R290. Certifications are said to be underway on additional product lines, including electric valves.

Parker Hannifin says it is also ready to support the refrigeration industry with products optimised for R448A and R449A, the lower GWP replacements for R404A. Products are also available for R1234ze, R450A, and R513A for use in chillers and many other high and medium-temperature applications.

New thermostatic charges for TEVs have been developed where appropriate to deliver the best broad-range superheat control with these new refrigerants. Parker ZoomLock and ZoomLine products are approved for use with HFOs, as well as most HFCs. Extensive material compatibility testing has been done by Parker, with support by Chemours’ and Honeywell’s labs to ensure long-term reliability and leak-free performance with HFOs and HFO-blends.

While much of the industry focuses on these new refrigerants, lower-GWP HFC refrigerants continue to play an important role in both new installations and retrofits. Sporlan offers a complete range of products for R407A, R407C, R407F, and other environmentally friendly replacements for high-GWP HCFCs and HFCs.

“This comprehensive range of products, along with expert technical support is key to helping our OEM and wholesale customers smoothly and quickly transition to the future with next generation low-GWP refrigerants,” said John Withouse, refrigerants technical lead for Parker.
