Bluon-TDX-20USA: The US EPA has SNAP-listed Bluon Energy’s alternative refrigerant TdX 20, aka R458A.

TdX 20 is described as a next-generation refrigerant blend for use as a replacement for R22, R404A, and R507A refrigerants used in existing HVAC and Refrigeration equipment.

With this latest SNAP notification, TdX 20 is now authorised for use in commercial comfort air conditioning, industrial process refrigeration systems, and retail food refrigeration. TdX 20 had previously received authorisation from the EPA in May 2015 for the sale and use in residential and commercial air conditioning.

TdX 20 is a patent pending blend of five approved EPA and ASHRAE constituents, said to improve energy efficiency and overall performance in existing HVACR systems. Comprising R134a, R32, R125, HFC227ea and HFC236fa, TdX 20 is non-ozone-depleting, non-fammable and non-toxic. It has a GWP of 1,650, just slightly lower than R22.

“This authorisation opens the door for the full refrigerant marketplace to take advantage of the many attributes of TdX 20 in saving energy, equipment, and the environment,” said Bluon Energy president and CEO Douglas Reinke.

The refrigerant is initially available in the USA, Australia and New Zealand.
