Huber Unichillers offer better efficiency, stable pressure and delivery performance with a constant cooling water temperature compared to traditional tap water cooling. Chillers also reduce water consumption and help conserve the environment whilst lowering operating costs. Unichillers are suitable for the removal of heat from chemical processes, cooling technical plants or as a central cooling water supply for laboratories. All Unichillers are designed for continual operation at ambient temperatures up to +40℃. Installation in an outside areas is possible with optional weather protection and winter operation packages. Pumps are available with an extended pressure and flow rate for applications with a high pressure drops.
The new multi-touch controller Pilot ONE offers a brilliant 5.7 touchscreen with graphic functions and a comfortable navigation menu. All important operating parameters and temperature values are neatly displayed on the touchscreen. Thanks to the new favourites menu, the one-click operation and the integrated technical glossary the operation is very easy, just like on a smartphone. Integrated USB and Ethernet ports allows connection to a PC or network, e.g. for remote control or data transmission.
