The Trane Thermafit air-to-water modular heat pump Model AXM is a fully electric modular unit that owners can scale to match a building’s heating or cooling load. By combining individually controlled AXM modules to create a single, larger heat pump, operators can right-size heating and cooling performance to meet a wide range of applications. Each module is capable of 30 tons of cooling and 390,000 MBtu/h of heating and is expandable to generate up to 300 tons of cooling. Dual refrigerant circuits on each heat pump provide precise temperature control. Controls with open standard protocols that seamlessly integrate with Tracer SC+ and third-party Building Automation Systems (BAS).
