Description

The closed loop chillers consist of an air-cooled high performance condenser combined with an encapsulated compressor. They are suitable for the installation in explosive gas atmospheres defined as Zone 1. The electrical control system is supplied with its own Ex-d housing. Optionally, with an analyzer, the control system can be placed inside the Ex-p housing of the analyzer. 

Problems on-site where utilities supplied cooling water is of a lower quality or special requirements of cooling water are needed, closed loop chillers can be applied to meet these applications. The chillers can be supplied with diverse refrigerating capacities which allow the chillers to be used on single analyzers up to complete analyzer houses, peltier elements and heat exchangers. They can be delivered suitable for indoor or outdoor use. Depending on the flow rate required, different pump capacities are also available.
