This type of cooling tower has a closed primary cooling circuit in which the cooling water cannot be contaminated or lost.
Cooling towers with a closed circuit work in principle like open cooling towers, but discharge the heat load of the process liquid via a heat exchanger coil to the ambient air. The process liquid is isolated from the outside air so that it remains clean and free of impurities in the closed circuit.
All closed cooling towers containing evaporation components have two separate liquid circuits: In the external circuit, spray water circulates through the tube bundle and is in contact with the outside air. Process liquid circulates in the tube bundle in the internal circuit. During evaporative cooling, the heat is transferred from the internal circuit via the tube bundle to the spray water and then as part of the evaporative water to the outside air.
We supply our customers with cross-component system solutions in the field of refrigeration, air conditioning and cryogenics. Our approach is to achieve the most efficient results possible with individual system components when it comes to maintenance, costs and energy.
