Haier has expanded its professional climate control portfolio with the launch of a new commercial air-to-water (ATW) monobloc heat pump utilizing R290 natural refrigerant. Designed for commercial applications such as hotels, offices, gyms, and restaurants, the system aims to support the transition toward lower carbon footprints and higher energy efficiency.

The new range is available in capacities of 26, 30, 35, and 40 kW. It provides an integrated platform for space heating, cooling, and domestic hot water production. For larger projects, up to eight units can be installed in cascade to reach a total capacity of 320 kW.

Technical features include Wi-Fi connectivity via the hOn app, a Modbus interface, and zone control for flexible climate management. To enhance safety and performance, the units are equipped with a refrigerant leak detector, a refrigerant separator, and a fully sealed electrical control box.
