Water Coils
Water coils for heating and cooling use copper tubes arranged between two end plates to allow water to flow through them. The tubes are connected to a set of fins, which are parallel to the direction of airflow. This arrangement enables energy to transfer either from the water to the air or from the air to the water via the tubes and fins.
All SPC water coils are made at the onsite manufacturing facility where they are tested to a minimum of 22 bar G air underwater.
Economy Casing
The 25mm flanged casings suit general ductwork applications. The flanges are supplied pre-drilled to aid installation. ‘Economy’ casings offer a compact and economical solution for smaller duct-mounted heating coils.
Standard Casing
The 45mm flanged casings suit general ductwork applications. The flanges are supplied pre-drilled to aid installation. For ‘standard’ cased cooling coils, the drain pan covers the fin block only.
Enclosed Casing
The 50mm flanged casing suits ductwork applications. They are complete with cover boxes over the headers and return bends to minimise air leakage. Welded and sealed cover boxes can be provided to further reduce air leakage. Drain pans on cooling coils extend under the headers and bends.
Unitary Casing
Unitary casing suits insertion into AHU or similar. It is complete with a baffle plate which is required to prevent air bypass to one or both faces. For cooling coils, the drain pan extends under the headers and bends. Alternatively, a perforated base is provided to allow drainage into a pan in the base of the AHU.
