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 2989 to make a rigid assembly.
Tube end plates have die formed collared holes to allow expansion and contraction of the tubes without damage.
Mounting
Duct mounting or replacement for exisiting heaters in Air Handling Units.
Accessoires
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.
