Advansor installs 1.2 MW CO2 heat pumps at Swedish retailer

Advansor has completed the installation of two ValueBox air-to-water heat pumps for an unnamed Swedish retailer, according to the company. Each unit provides 600 kW of heating capacity, resulting in a combined system capacity of 1.2 MW.

System configuration

The system utilizes carbon dioxide (R744) as its refrigerant. Both ValueBox units are installed outdoors adjacent to the building. Advansor has not disclosed the project’s specific location, commissioning date, or efficiency figures.

Product specifications

Advansor ships the ValueBox systems in a complete, pre-tested condition. Every unit combines several evaporators, an exterior housing, a water pump, and associated control hardware. The architecture features built-in defrost management, a touchscreen interface for oversight, and shielding mesh around the evaporator fins. Installing the system on-site involves linking the units to the facility's current water and power supplies.

Performance and range

Advansor introduced the ValueBox range in January 2025. The product line covers individual unit capacities from 200 kW to 700 kW. While the initial launch included heating capacities of 311 kW to 654 kW and cooling capacities of 308 kW to 365 kW, the broader range extends to the higher maximum. The system achieves a heating coefficient of performance (COP) of approximately 2.68 to 2.69, with a combined heating and cooling COP reaching up to 5.56. The units can supply water at a maximum temperature of 95 C.

Metric	Value
Heating capacity per unit	200 kW – 700 kW
Initial heating capacity range	311 kW – 654 kW
Initial cooling capacity range	308 kW – 365 kW
Heating COP	~2.68 – 2.69
Combined heating/cooling COP	Up to 5.56
Max water output	95 C
Parallel operation capacity	5 MW+

These figures indicate that multiple units can operate in parallel to reach capacities of 5 MW or more. Under suitable site conditions, installation of the units requires one or two days.

Background

• Italian scientists developed a 10 kW direct-expansion, dual-source heat pump prototype using CO₂ refrigerant, as highlighted by Luminity on 23 Oct 2026.
• The unit utilizes Air-Mode through a fan-assisted evaporator and Sun-Mode via photovoltaic-thermal collectors to boost COP.

Installation logistics and design rationale

Engineered to be trucked to the job site, the units feature a frame that simplifies lifting and placement. The maker claims this ready-to-use method overcomes the lack of qualified installers by providing factory-built, pre-programmed, and pre-charged equipment containing CO₂ and oil. Per details released at the January 2025 debut, the configuration removes the requirement for extra perimeter fencing. Additionally, the firm highlights that the machinery sustains heat production even during defrost phases, a capability they assert renders it appropriate for commercial space heating, residential hot water, and industrial uses.
