The chiller and pumping system shown here is designed for cooling a radar system and will be installed outdoors. Our engineering team designed a special loop-in-loop system that consists of a 40 ton air cooled chiller and stainless steel plate and frame heat exchanger (loop 1), that same exchanger, a 15 HP pumping system and the radar system itself (loop 2).

The radar in this instance required approximately 40 tons of cooling which is provided by the ACC600 General Air Products air cooled chiller. The chiller uses its internal 3 HP pump to move the water glycol mix through the stainless steel plate and frame heat exchanger. The next part of the loop-in-loop design of this radar cooling system begins on the other side of the heat exchanger. A 15 HP vertical 7 stage pump moves a water glycol mix from the heat exchanger, up the side of a building and then to the radar system itself. The water in the radar loop is filtered by 1 micron filters by customer request and is regulated by a back pressure regulator so that the system pressure does no exceed 165 psi in the event of the pump being dead headed. All components in the radar cooling loop are non-ferrous / stainless steel.

By using a loop-in-loop design for this radar cooling application we were able to save our customer a significant amount of money. Without it they would have needed to purchase a highly custom chiller with non-ferrous or stainless steel internal parts. While we have the capability to create a chiller that meets that requirement, we always keep in mind the best, most cost effective solution possible.
