Beijer Ref Group operates several production units both in and outside Europe, manufacturing compressor units for refrigeration systems, industrial heat exchange units, and heat pump systems for commercial buildings. One of the group's most prominent names is the trans-critical CO2 booster units produced by SCM Frigo, specifically for commercial refrigeration. SCM Frigo's trans-critical CO2 booster units are well-known in commercial refrigeration, with the first CO2 units being installed nearly 20 years ago. Today, the product range has expanded from commercial to industrial refrigeration, and as a result, units can be found in many cold stores and production facilities. The cooling capacities of the units range from 1 kW to 1 MW. Both standard solutions and compressor units tailored to customer requirements are manufactured.
