Performance Characteristics

The new Unichiller CO2 is another milestone in environmentally friendly refrigeration technology at Huber. The new chiller uses CO2 as a refrigerant. CO2 or carbon dioxide (also known as R744) is a natural component of the air and has been proven in refrigeration since the 19th century. It is a colorless gas liquefied under pressure. It has no ozone depletion potential (ODP = 0) and has a negligible greenhouse potential with a GWP = 1. If, for example, 1 kg of CO2 enters the atmosphere through a leak in the refrigerant circuit, this is 3780 times less damaging than with the conventional R404A refrigerant. In addition, CO2 is a so-called natural refrigerant, which occurs in very large quantities in nature, i. it does not have to be generated with great energy expenditure.
In addition, CO2 has other advantages: It is non-flammable, non-toxic and chemically inert.
The new Unichiller CO2 is therefore a 100% environmentally friendly alternative to refrigerators with conventional synthetic refrigerants. The Unichiller CO2 offers pioneering refrigeration technology and Huber's proven chiller technology.

Please take further technical information as well as information about the scope of delivery, accessories and peripheral devices from the PDF data sheet. In cases of doubt the details given in there apply. If nothing to the contrary is quoted then the performance data referred is at an ambient temperature of 20°C.

Please observe the notes on installation and/or the space requirements of our products.

The following voltage and frequency tolerances apply based on EN60034-1:
Voltage +/- 5% for a frequency tolerance at the same time of +/- 2%

Examples to illustrate this: Not permissible, for example. is -5% on the voltage and +2% on the frequency. Permissible, on the other hand, are tolerances of -5% on the voltage and -2% on the frequency.

We reserve the right to make technical changes and correct errors. Illustrations can deviate from the original.
