Danish OEM Advansor has announced the release of HeatQuantum, a new air-to-water plug-and-play CO2 (R744) heat pump that provides 200‒600kW (56.9‒170.6TR) of heating capacity.. 

According to a press release, Advansor’s goal is to speed up the green transition by providing a large heat pump that is factory tested and can be installed using a building’s existing piping and heating elements. Advansor’s website says the HeatQuantum, available in four different models, can be delivered and up and running in eight hours.

“One of the key limitations in the green transition is lack of skilled people onsite,” said Advansor CEO Kristian Breitenbauch. “When a HeatQuantum leaves our factory, it is fully assembled and ready to be plugged in and turned on; just connect water and electricity, and you are up and running.”

According to Advansor CTO Kenneth Bank Madsen, the whole unit – including evaporators and the machine unit – is built on a single frame, making it “fast and easy” to load and unload the heat pump via crane. 

HeatQuantum supplies water at temperatures of up to 85°C (185°F) for process heating, hot tap water and space heating with a COP of up to 3.24. Units can be connected in parallel for higher-capacity applications.

Ivan Rangelov, Business Development Manager for Industrial Heat Pumps at Danfoss, wrote on LinkedIn that the HeatQuantum is equipped with BOCK CO2 compressors, specifically its semi-hermetic HGX34 and HGX46 models. Danfoss completed its acquisition of Bock in March 2023.

Built for the cold

Advansor said the HeatQuantum was designed “specifically with cold climate performance in mind” and that it can run efficiently at ambient temperatures as low as −20°C (−4°F). The heat pump is equipped with integrated defrost control and can produce heat during defrosting cycles.

On its website, Advansor says the HeatQuantum’s “advanced evaporator design” assists in the defrosting process. The heat pump is also enclosed to protect it from the elements.

At ambient temperatures of −20°C and with a water inlet temperature of 40°C (104°F) and an outlet temperature of 80°C (176°F), Advansor says its four HeatQuantum models have the following heating capacities:

  • HeatQuantum 250: 215kW (61.1TR)
  • HeatQuantum 400: 306kW (87TR)
  • HeatQuantum 500: 472kW (134.2TR)
  • HeatQuantum 600: 455kW (129.4TR)

Advansor called the HeatQuantum a “game-changer” in replacing fossil fuels, particularly oil and gas burners during building refurbishment projects. 

“It is key to move away from oil and gas burners, and with the HeatQuantum this has become easier than ever,” said Breitenbauch. “We have created a future-proof solution that will help our customers fulfill their climate action goals.”

Headquartered in Brabrand, Denmark, Advansor provides CO2 climate solutions for small to large applications. Besides heat pumps, the company’s products include CO2 boosters, racks and chillers.

“When a HeatQuantum leaves our factory, it is fully assembled and ready to be plugged in and turned on; just connect water and electricity, and you are up and running.”
