Denmark-based heat pump manufacturer Advansor has installed two ValueBox air-to-water heat pumps at a large retail building operated by an unnamed Swedish retailer. Each unit has a heating capacity of 600 kW, providing a combined capacity of 1.2 MW to meet the building’s heating requirements.
Advansor has not disclosed the location of the installation, its commissioning date or project-specific efficiency figures.
The heat pumps are installed outdoors next to the building and use CO₂ (R744) as a refrigerant. Advansor said the plug-and-play design simplifies transportation, installation and commissioning, as the units are delivered fully assembled and factory-tested.
Each ValueBox is supplied as a single frame-mounted unit incorporating multiple evaporators, an outdoor enclosure, a water pump and integrated control equipment. The systems are designed to fit on a truck for transportation, while the frame facilitates lifting and positioning on site.
According to Advansor, installation primarily requires connections to the building’s water and electricity infrastructure. The units are pre-charged with CO₂ and oil, pre-programmed and tested at the factory to reduce on-site commissioning work.
The heat pumps also feature integrated defrost control, a touchscreen for monitoring and operation, and protective mesh around the evaporator fins, eliminating the need for additional fencing around the equipment.
Advansor introduced its ValueBox range in January 2025 , targeting commercial and industrial heating applications. At the time, the company said the systems could provide between 200 kW and 700 kW of heating capacity per unit, with multiple units operating in parallel to achieve capacities of 5 MW or more.
