Hot Water Heating Coils

Hot water air heating coils – for air conditioning and process heating – using LPHW, MPHW, HPHW, or Low Grade HW generated from other equipment.

Hot water heating 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 hot water flows through the tubes from the connection header manifolds into individual circuits formed with copper return bends. The heat is transferred from the hot water flowing through the tubes to the air which flows over the fins and tube assembly.



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.

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.
