Zero ozone depleting potential
23 February 2024
AS OF 2024, the entire Tundra range of refrigerant air dryers from Hi-line Industries will transition to R-513A, a refrigerant with zero ozone depleting potential (ODP) that helps customers to enhance their sustainability credentials.

R-513A (Opteon XP10) refrigerant is a hydrofluoroolefin (HFO) based replacement for R-134a. Ideal for use in medium and low temperature refrigeration products, such as Tundra air dryers, R-513A offers 56% lower GWP (global warming potential) than R-134a, delivering long-term sustainability and F gas legislation compliance.
Notably, R-513A resides in the A1 (non-flammable) safety class, making it an ideal retrofit candidate for R-134a, while offering very similar cooling performance. R-513A also provides negligible temperature glide to ensure reliable performance.
Among further features driving Tundra’s energy-efficient characteristics is a patented single-cell heat exchanger, which delivers highly efficient heat transfer at low energy costs, and a link between the controller and condensate removal valve for minimum loss of compressed air during condensate discharge.
Despite the new innovation in refrigerant development, Hi-line intends to hold pricing for the Tundra range firm throughout 2024.
