Dry cooler GRAS

The GRAS dry cooler comprises a plate-type heat exchanger made of copper-aluminum alloy plus one, or several, axial fans mounted in a single case. Outward heat transmission is achieved by means of air flow, supplied by fans, and passed through the heat exchanger.

This dry cooler is designed for outdoor installation. The dry cooler casing is made of galvanized steel and coated with special water-proof paint.

Water, or water-glycol solution, is used as the coolant. Glycol content depends on local on-site climatic conditions.

So as to better meet customers’ exact requirements, the GRAS dry cooler has a modular structure. A wide range of cooling capacity can be achieved simply by changing the number of fans mounted in a single case, with a heat exchanger of corresponding thermal performance.

Dry coolers are used in cold supply systems, including free cooling and recycling water supply applications.
