Deionized Process Cooling Systems
Our packaged deionized process cooling system designs have proven to be a benchmark solution with outstanding reliability, robust construction, and superior automation for the most challenging industrial environments. Our systems are specifically engineered and manufactured for providing process cooling water in applications requiring deionized or high resistivity fluid, such as microelectronics manufacturing and research.
OPEN LOOP
The envirosep PCW-DI open loop design package is a variable speed system which includes a water storage tank. The nitrogen-blanketed, storage tank provides additional system volume for systems which require precision temperature control in intermittent load. System lag pump(s) are automatically staged on/off based on actual system requirements. Envirosep engineers can provide open loop system designs to meet specific site criteria.
CLOSED LOOP
The envirosep PCW-DI closed system designpackage is also a variable speed system which provides process cooling water in applications requiring deionized water or high resistivity fluid. The closed loop system arrangement provides precision temperature and flow control in processes with relatively continuous loads. System lag pumps are automatically staged on/off based on actual system requirements. Envirosep engineers can also provide closed loop system designs to meet specific site criteria.
