With the new Unichiller 220Tw CO2, Huber Kältemaschinenbau presents another milestone in environmentally friendly refrigeration technology.

The new chiller uses CO2 as a refrigerant. CO2 or carbon dioxide (also known as R744) is a natural component of air and has been proven in refrigeration since the 19th century. The colourless gas liquefied under pressure, has no ozone depletion potential (ODP = 0), and has a negligible greenhouse gas potential with a GWP = 1. If, for example, 1 kg of CO2 enters the atmosphere through a leak in the refrigerating circuit, this is 3780 times less damaging than with the conventional refrigerant R404A.

In addition, CO2 is a so-called natural refrigerant that occurs in very large quantities in nature (it does not have to be generated with great energy expenditure). In addition, CO2 is non-flammable, non-toxic and chemically inert.

The new Unichiller CO2 is, therefore, an environmentally friendly alternative to refrigerators with conventional synthetic refrigerants. The Unichiller is designed for working temperatures from -20°C to 100°C, and offers a cooling capacity of 22kW and a heating capacity of 12kW. The circulation pump achieves a delivery rate of 200l/min and 4.6bar pressure.

The cooler is equipped with the Pilot ONE touch-screen controller and therefore has numerous professional functions for demanding temperature control tasks.

Advantages of the Unichiller 220Tw CO2 include:

  • Proven Unichiller technology
  • Environmentally friendly refrigeration technology
  • Ozone depletion potential equal to zero (ODP = 0)
  • Global warming potential negligible (GWP = 1)
  • Very good energy efficiency
  • Refrigerant non-flammable, non-toxic
  • High operational safety
  • Future-proof investment
