Klima-Therm has won the prestigious Commercial Air Source Heat Pump of the Year Award in the ACR News Awards for the Rhoss POKER290, a pioneering new range of high-temperature, low-GWP air-cooled reversible heat pumps.
The victory was announced at the Grand Connaught Rooms in London on April 10th.
The POKER290 is a high-temperature, low-GWP air-cooled reversible heat pump designed to deliver exceptional performance across a wide operating range. With the ability to produce hot water up to 75°C and maintain operation at outdoor temperatures as low as –20°C, it offers a powerful, future-ready alternative to conventional heating systems. The unit uses R290 natural refrigerant, known for its ultra-low GWP and non-toxic, environmentally friendly properties, eliminating F-gas regulatory concerns and supporting long-term decarbonisation goals.

What Makes the Rhoss POKER290 Range Award-Winning?
High-temperature performance & extended operating limits
The POKER290 delivers exceptionally high hot-water temperatures, reaching up to 75°C even under challenging winter conditions. Supported by advanced scroll compressors and optimised R290 refrigerant performance, the system maintains reliable operation at outdoor temperatures down to –20°C. This wide operational envelope ensures year-round capability for heating, domestic hot water, and process applications, making it suitable for both new low-carbon installations and the replacement of traditional boiler systems
High Performance in all Climates
Engineered for versatility, the POKER290 is designed to operate efficiently in cold, temperate, and hot climates. In addition to its strong winter performance, the unit delivers excellent summer capability by producing chilled water for air conditioning or industrial processes, with temperatures as low as –10°C. This combination of high-temperature heating and effective cooling ensures consistent performance across diverse building types and environmental conditions. The result is a reliable, all-season solution for commercial and industrial sites.
Remote Monitoring and Safety
The system integrates advanced control technologies, including the dynamic master SDR, which coordinates up to four units in parallel and provides intelligent power modulation and domestic hot-water management. Remote monitoring is available through Rhoss’ SYS-TO system and optional touch-screen controls. Safety is built in at every level: the unit incorporates an infrared gas sensor, automatic shutdown procedures, ventilation logic, and gas-leak detection systems to prevent hazardous atmospheres. This ensures safe operation even with a natural refrigerant, giving operators full confidence in system performance.
Energy Saving & Heat Recovery
The POKER290 includes several features designed to reduce energy consumption and maximise system efficiency. With SCOP values up to 3.81 (LT) and high part-load performance, the unit delivers strong efficiency throughout the year. Integrated energy-saving functions support the optimisation of generators, domestic hot-water production, and distribution networks. Optional partial heat recovery through a desuperheater allows free reclaimed heat to be reused within the building, further lowering running costs. Combined with low-noise EC fans and advanced electronics, the overall system achieves a balance of efficiency, sustainability, and operational comfort.
