Hubar Unichiller 025 OLÉ

Category Chillers
Manufacturer Huber
Country of manufacture Germany

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°C. 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 OLÉ controller combines state-of-the-art technology with simple operation. OLÉ models are suitable for routine tasks in research and industry and are convincing as practice oriented basic equipment. Option: Pt100 sensor connection #10519 to display (not control) e.g. of the process temperature (only available factory fitted, additional charge).
