MFG Part Number 1264.00

OL4503

WL Series Liquid Cooling System

Oil cooled systems OL4503 is designed to circulate transformer oil and are used in applications where the temperature at the heat source exceeds the operational temperature limit of water?based coolants, or when special insulating properties are required within the coolant loop. The OL Series is a recirculating liquid to air heat exchanger that offers dependable, compact performance by removing large amounts of heat from a liquid circuit. The coolant pump to assure maximum flow rate. The coolant is recirculated using a high-pressure pump to assure maximum flow rate. Heat from coolant is absorbed by a heat exchanger and dissipated into the ambient environment using brand name fan.
