Chilled Water Cooling Coils
Chilled Water Cooling Coils are fluid to air heat exchangers. Generally constructed from copper tubes mechanically expanded into aluminium plate fins with self spacing collars to ensure efficient heat transfer. The Chilled water flows through the tubes from the connection header manifolds into individual circuits formed with copper return bends. The heat is transferred from the air flowing over the fins and tubes into the water flowing through the tubes. The coil assembly is contained in a sheet metal casing with a drain tray to collect the condensate which will be produced when the air is cooled below dew-point. Where moisture carryover over may occur due to air velocity or condensate load, moisture eliminator plates are fitted to prevent carryover into the air stream.
