Delta Cooling Towers, Inc products

Certain processes require a closed-loop, whereby the process water for cooling does not come in contact with the atmospheric air. This preventsthe cooling water from picking up particles that may not get filtered or even dissolved gases. Closed-loop cooling requires more energy and has higher initial and life-cycle costs than an open cooling tower, but provides an added protection to expensive processes or chillers being cooled. For closed-circuit cooling, Delta recommends a cooling tower plus a plate heat exchanger system. The skid-mounted plate heat exchanger provides a closed circuit on the hot side of the heat exchanger. The noncorroding Delta cooling tower feeds the cold side of the plate heat exchanger.
