T Series HDPE pump tank systems sometime are used in place of dry coolers or evaporative cooling towers. You get consistant supply water temperature year round regardless of the ambient air temperature and the process heat is being rejected by the outdoor chiller. The operation consists of glycol pump tank pumping cold EG or PG to the heat exchanger through a 3-way valve and recirculates it. The H2O cirulation pump pumps distilled water through the hot side of the heat exchanger and re-circulates it back to the water tank. A larger supply water pump pumps 35-100F water to the process. Temperature is maintained via a 3-way brass control valve modulating glycol through the cold side of the heat exchanger to maintain supply water temp.
