Performance Characteristics

The new Unichiller GL generation (Green Line) expands the Huber portfolio with a sustainable, high-performance and investment-safe cooling solution for industry and research. The circulation chillers, housed in a space-saving tower enclosure, are suitable for a wide range of cooling tasks – from precise process cooling and temperature control of test benches to the operation of laboratory equipment. With temperature ranges from -20 °C to +40 °C, scalable cooling capacities and high-performance circulation pumps, the Unichiller GL guarantees highly dynamic heat transfer and a high level of operational reliability.
Operation is via the Pilot ONE controller with a 5.7-inch colour touchscreen display. Key parameters are visible at a glance, and modern digital interfaces ensure seamless integration into control systems. The chillers offer impressive economic benefits thanks to minimised operating costs, efficient energy management and comprehensive safety features for unattended continuous operation.
A key highlight is the consistent use of the natural refrigerant carbon dioxide (R-744 / CO₂). As a natural component of the atmosphere, CO₂ has no ozone-depleting potential (ODP = 0) and a negligible global warming potential (GWP = 1). Furthermore, R-744 is non-flammable, non-toxic and is not subject to any restrictions under the European F-Gas Regulation. Unichiller GL units therefore offer operators a 100 per cent environmentally friendly and future-proof alternative to synthetic refrigerants.

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.
