Action on Green Heating Solutions


Whether in industrial, commercial or residential application, heat pump has been recognized as the most eco-friendly and sustainable heating solution, it is a mature product in 21st century. Due to suffering global warming challenge, many countries start promoting natural refrigerant and HFO low GWP refrigerants. 

KAORI Action on Green Heating Solutions

Heat pump manufacturers also upscale the portion of new refrigerant products in the product portfolio. One of them is the R290 (Propane), it has high heat transfer efficiency, and the eco-friendly features are also get noticed by the industry. The performance is equivalent to HFC refrigerants, low GWP and zero ODP features are extra benefits for a sustainable ecosystem.
In the new generation of R290 heat pump, the charge is limited, and a highly efficient heat exchanger is needed in order to reach high COP.  KAORI as one of the world's leading manufacturers of the brazed plate heat exchanger, we take pride in offering our innovative optimal solutions to customers. These include the original K series, the microchannel R series, and the new released asymmetric B series.

Kaori's K series is the most widely used product, the advantage is its stable heat transfer efficiency and superb assembly quality, especially K070 and K105 are the most popular models with a long history. Kaori's R series adapts the microchannel design; its compact design reduces the weight up to 27% and saves up to 20% refrigerant charge. The unique plate pattern design further helps to achieve better refrigerant distribution, reducing the chance of clogging refrigerant oil, improving heat transfer performance, at the same time reducing the risk of ice and compressor damage due to abnormal in refrigerant oil backflow.

Kaori begins its close cooperation with a well-known Polish professional water heater and heat pump manufacturer HKS LAZAR, providing the best heat exchanger solution in HKS LAZAR’s new R290 heat pump development. HKS LAZAR is a family-owned company that has a leading position in Poland and Europe manufacturing heating devices (Pellet boilers, air-water heat pumps with R290 refrigerant). The company has been established since 1937. At present, the network including over 400 partner companies provides service across whole Europe.
