Water cooling system

Certain processes require a closed-loop, whereby the process water for cooling does not come in contact with the atmospheric air. This prevents the 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 non-corroding Delta cooling tower feeds the cold side of the plate heat exchanger.

The advantages of this system over a closed-circuit cooling tower (usually galvanized sheet steel and galvanized steel coil inside a cooling tower box) are:

Cost: Typically Costs Less to purchase & operate
HP: Less Total HP required, Green solution
ASHRAE 90.1: Performance requirements for heat rejection equipment show closed-circuit cooling towers use 2.5 x more HP
Warranty: Delta cooling tower has 20-Year casing warranty versus 1-Year on galvanized steel
Expandability: Heat Exchanger can handle future load increase by adding plates
Maintenance: Heat Exchanger has Stainless Steel plates and is much more accessible than coil for easy cleaning
Weight: Delta tower is 3-7 times less weight saving rigging and structure costs
Install Flexibility: Heat Exchanger skid can be placed indoors without need to maintain Glycol solutions necessary with outdoor coil
