Heating coils HW
Aircoil heating coil type HW
HW heating coils are used for heating air or cooling fluid. Ideal for installing in ducts with a guide or flange connection, or for embedding in a unit.
- The headers have plugged outlets for aeration and discharge (1/8″).
- Equipped with an outlet for an immersion sensor (1/4″) when the number of circuits is higher than one.
- Connections on the fluid side have external pipe threads up to and including DN 80.
The coils are labelled to indicate the inflow and outflow on the fluid side, as well as the air direction.
The connection dimensions and the construction depth of the coils varies according to the number of tube rows, as stated in the technical calculation.
The A, B and C models can all be equipped with either a Guide (G) or Flange (F).
Type A
Open ends with visible headers and tube bends outside the connection dimensions.
Type B
Covered ends with capped headers and tube bends outside the connection dimensions.
Type C
Covered ends with capped headers and tube bends inside the connection dimensions.
Type IA
Inside the unit, adapted with millimetre precision to the interior width and height of the unit.
