CO₂ (R744) Systems

Our [CF] SYSTEMS series for the natural refrigerant CO₂ offer long-term applicable and efficient solutions for a variety of applications. In many areas, this technology has already established itself as the new standard.

Thanks to its thermodynamic properties, the refrigerant CO₂ enables a wide range of applications, from commercial refrigeration to industrial, process, and high-temperature heat pump segments.

Why CO₂?

Synthetic refrigerants are increasingly reaching a dead end due to the requirements of the European F-Gas Regulation and the impending REACH procedure for PFAS restriction. Manufacturers and operators are called upon to increasingly switch to alternative refrigerants with lower GWP or directly to natural refrigerants such as CO₂, propane, or ammonia.

Compared to its natural competitors, CO₂ scores points because the substance is non-flammable. Technically, CO₂ also offers numerous advantages. The high discharge temperatures and transcritical operation enable efficient use of waste heat. Pressure losses affect efficiency significantly less than with other refrigerants. In addition, the upstream pressure before the injection valves remains constant throughout the year due to the special refrigeration circuit design – which ensures stable and precise control of the evaporators.
