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 blades are fitted to prevent carryover into the air stream.

Specification:

Coils are constructed from Seamless Drawn Copper – to BS EN 12449 – mechanically expanded into aluminium fins with die-formed self-spacing collars. Copper return bends and tubular copper headers are silver brazed into the tube ends. Flow and return connections are BSP(M). Air vents and drain sockets are provided. The coil casing is formed from heavy gauge galvanised sheet steel – to BS EN 10143 – to make a rigid assembly. Tube end plates have die formed collared holes to allow expansion and contraction of the tubes without damage. Drain trays are provided as standard, v-formed with an air baffle to prevent air bypass, and a BSP(M) drain connection. Alternatively, perforated bottom plates may be provided to allow drainage into the customer’s own drain tray.

Optional Features:

Polyester coated aluminium fins are available to give protection in certain aggressive environments. Alternatively, plain copper or tinned copper fins are available.

For positive pressure or high pressure ducted systems, boxed ends should be specified to enclose headers and return bends, and minimise air leakage.

Brass, Aluminium or Stainless Steel casings are also available.
