Airedale by Modine has introduced the MultiChill Propane, a modular air source heat pump chiller operating with natural refrigerant R290. Targeting sustainable cooling and heating in the UK, the new unit offers flexible applications and high performance for commercial, industrial, and domestic use.
Available in seven sizes, the MultiChill Propane delivers cooling capacities from 35 kW to 73 kW (approx. 119,400 to 249,000 BTU/h) and heating capacities from 40 kW to 86 kW (approx. 136,500 to 293,400 BTU/h). It supports water temperatures up to 75°C (167°F) and achieves seasonal performance ratings of SEER 5.36, EER 2.86, and SCOP W55 3.63. The units use R290 (GWP 3), classified as an A3 refrigerant under BS EN 378-1, indicating low toxicity and high flammability.
Engineered for modular deployment, up to 16 MultiChill units can be networked for a total cooling capacity of 1168 kW (approx. 3.99 million BTU/h) and heating capacity of 1376 kW (approx. 4.7 million BTU/h). Each unit includes an integrated system tank and compact footprint, suited for legacy site retrofits or constrained installations.
To address acoustic and spatial considerations, the MultiChill Propane offers three sound configurations. Safety measures include refrigerant leak detection, a dual-compartment separation between electrical and refrigerant systems, and an air purge mechanism for refrigerant release and ventilation.
With increasing demand for low-GWP refrigerants and efficient heat pump technologies in the UK, the MultiChill Propane supports both decarbonization goals and F-gas regulation compliance. It is backed by Airedale’s UK-based 24/7 service, warranty, and technical support.
“The MultiChill Propane is a groundbreaking addition to Airedale by Modine’s sustainable range of commercial and industrial heat pump chillers,” said Simon Scott, Commercial Director at Airedale by Modine. “Critical to industry, propane delivers a high efficiency solution. Like most things, as long as safety protocols are followed, it is safe to use.”
