BELGIUM: In addition to a next generation Altherma 4, Daikin Europe is set to launch new heat pumps running on lower GWP refrigerant R454C and propane (R290).

The new Daikin Altherma 4 series will previewed at the forthcoming ISH exhibition, with its launch planned from 2024.

Daikin says it will continue to offer a wide portfolio using R32 refrigerant but, In addition, based on expected high demand for heat pumps in Europe, it will also launch a new range of air-to-water heat pumps with R454C refrigerant.

“This lower GWP refrigerant offers a wide range of installation possibilities, making it suitable for the different types of housing structures throughout Europe,” Daikin said in a statement.

An A2L refrigerant with a GWP 148, R454C is a blend of R32 and 1234yf. The refrigerant has already been adopted by a number of heat pump manufacturers, including rival Mitsubishi Electric and MHI.

In addition, Daikin says that certain product ranges will be provided with R290 “where the complete refrigerant circuit is installed outside, and where feasible from safety aspects”.

“Just as Daikin did for other refrigerants, and will also do for units with R290, it will take specific safety measures considering the total life cycle of the equipment,” the company said.

In recent months, Daikin has been steadily investing in both product development and manufacturing sites in Europe. Last year, the company announced it would build a new heat pump factory in Poland, which is expected to be operational by mid-2024.

The first tangible results of these investments will be visible at ISH 2023 in Frankfurt from 13 to 17 March, with the presentation of the new Daikin Altherma 4 heat pump series.

Daikin reveals that new range will contain tailor-made components that enhance performance, add application flexibility while also safeguarding each stage of product lifecycle. It will feature a new touch-screen controller, remote control possibilities and remote troubleshooting. It will also be compatible with third party home automation systems and home energy management systems.
