Duct heater with spigot connection for standard spiral
ducts. Manufactured from Aluzinc-coated sheet steel with
a heating element in stainless steel. The heater has inte-
gral overheating protection with a manual reset function.
The CB heater has rubber seals on the connecting spigots.
Suitable for control by room thermostat or Pulser.
The minimum air volume is based on a minimum air
velocity of 1.5 m/s. These duct heaters are designed for
a maximum output air temperature of 50°C. The CB can
be installed in a horizontal or vertical duct. In a horizon-
tal duct, the connection box should be installed facing
upwards, or rotated 90° to one side. Installation with the
connection box facing downwards is not allowed.
