Unlike the refrigerated chilling system it will replace, the LC-Series heat exchanger is very efficient. Tests confirm a reduced refrigeration load of 170 HP, which translates into electrical power savings estimated at $77,000 annually. Heat exchanger uses ambient air to cool, which is key to high-energy savings. Basic components include outer housing, fin-tube core and heavy-duty fan. This unit will be used to cool 34 GPM of caustic liquid that is circulating through stainless steel tubing. Liquid is cooled from 180°F to 120°F in 90°F ambient, rejecting 1,020,000 BTU/hr.
