Profroid has introduced the HeatCO2OL range of industrial heat pumps using CO2 as a natural refrigerant. The units are designed to deliver hot water up to 90°C and cover heating capacities from 400 kW to 2.2 MW, making them suitable for district heating, commercial buildings, and industrial process applications.
The HeatCO2OL series can utilize natural heat sources such as groundwater, lake water, sea water, and geothermal energy, as well as waste heat from industrial processes, grey water, boilers, and chillers. By recovering and reusing heat, the units aim to support decarbonized heating solutions and contribute to Net Zero objectives.
The heat pumps can manage up to three simultaneous heating temperature levels and, in some configurations, produce chilled and hot water simultaneously. Factory-assembled units are leak- and function-tested, with CO2 refrigerant providing low environmental impact (GWP 1, ODP 0) and eligibility for incentives in several European countries.
Case studies in Denmark and Norway highlight applications such as district heating, process cooling with heat recovery, and integrated building heating and air conditioning. In Padborg, a single HeatCO2OL connected to industrial grey water supplies 1,200 kW of heat to the local district loop, achieving a COP of 3.7.
The series offers compact dimensions, modular installation for large capacities, and connectivity for remote monitoring. Units are designed for low total cost of ownership, with compressor bearings rated for 100,000 hours and minimal preventive maintenance requirements.
