[INQ. NO. 2609M05] Dong Hwa Win Co., Ltd. has developed an air-cooled condenser utilizing A2L and R290 refrigerants to respond to the recent trend in the refrigeration and air conditioning industry, which is shifting from conventional high-GWP refrigerants to systems using low-GWP and natural refrigerants.
Dong Hwa Win has equipped this product with Danfoss and Copeland compressors to ensure stable operation.

In particular, for models using R290 refrigerant, an inverter system has been applied to improve energy efficiency, allowing the compressor’s operating capacity to be adjusted according to the refrigeration load.

Additionally, products equipped with Danfoss and Bitzer inverters are also being introduced to improve the operational efficiency of various refrigeration systems. Meanwhile, the DUES series (unit coolers) features an integrated fan motor to achieve efficient heat exchange and stable cooling performance.
Dong Hwa Win plans to present a product-development direction at HARFKO 2026 that considers not only changes in refrigerants, but also reflecting market demands for improved energy efficiency.
