Andalusian manufacturer Keyter is to use Honeywell’s HFO refrigerant R1234ze in a commercial scroll chiller for the first time.

Mitsubishi Heavy Industries has delivered two R1234ze(E) centrifugal chillers with a total cooling capacity of 8,400RT to Singapore’s Marina Bay district cooling facility.

Bitzer, the refrigeration and air conditioning specialist presents its SPEEDLITE ELV52 scroll compressor, which was specially developed for electric buses and rail vehicles.

The City Advantage is a new Trane range of compact scroll water-cooled chillers and water-source heat pumps with lower GWP refrigerant R454B refrigerant.

Mark Hughes of Chemours told that an industry-wide shift to lower GWP refrigerants would require new ways of thinking about engineering priorities. This focus on moving to lower GWP refrigerants has been a central focus for the HVACR industry to meet legal targets set out in the EU and UK’s F-Gas regulations.

Honeywell announced that its new Solsticeyf UV – a low-global-warming-potential (GWP) refrigerant incorporating ultraviolet (UV) dye for leak detection support in automobile air conditioning systems – is now available at all participating NAPA Auto Parts stores across the United States. This is the first time Solstice yf (R-1234yf) refrigerant with UV dye will be available in the aftermarket.

Carrier Transicold is to make lower GWP refrigerant R452A the standard gas for all new transport refrigeration units in North America from October.

Daikin has recently been involved in the commissioning of three water-cooled R1234ze chiller units at CERN, the European Organisation for Nuclear Research and home of the Large Hadron Collider.

Kaltra handed over a low-GWP chiller from its most innovative, ErP 2021 compliant Lightstream Screw II lineup to the client in the UK.

A new Daikin refrigerant announced last year as a more efficient alternative to R1234yf in electric vehicles has been designated as R474A by ASHRAE and given an A2L classification.

Bitzer’s Ecolite condensing units are now available for use with a full range of A2L refrigerants, including ultra-low GWP R1234ze/yf and lower GWP R455A and R454C.
