The latest Hi-line Tundra refrigeration dryers contain R513a, an A1 safety group refrigerant which is neither toxic nor combustible.

UK manufacturer of compressed air purification equipment, Hi-line Industries, has released the 2021 version of its energy-efficient Tundra refrigeration dryers, which includes a switch to R513a refrigerant.

R513a refrigerant is a HFC/HFO blend, has no Ozone Depletion Potential (ODP) and a much reduced CO2 impact compared with the previous R134a refrigerant.

The F-Gas regulation means that refrigerants with a Global Warming Potential (GWP) of more than 2500 are now subject to a ban. However, while R134a is below this limit and remains legal, regulations stipulate an incremental phasing-down of production quotas to help reduce environmental impact. R513A is widely viewed as the optimum replacement.

R513a is an A1 safety group refrigerant and is neither toxic nor combustible. Unlike flammable refrigerants, R513a is subject to less stringent regulations in handling, maintenance intervals and compulsory leak tests, saving time and money.

Switching to R513a builds on the sustainable credentials of the Tundra range, already known for its optimised energy efficiency via capabilities such as minimal pressure drop and lower absorbed power.
