CB 125-1,2 230V/1 Duct heater#5290
Frequency: 50 Hz

Wide range

Duct heater available in wide range of connection diameters up to 400 mm and capacities up to 12 kW.

Robust materials

The electrical duct heater is manufactured from aluzinc-coated sheet steel with a heating element in stainless steel.

Flexible installation in spiral ducts

The electrical duct heater has a spigot connection with rubber sealings for fitting to standard spiral ducts and designed for installation in both a horizontal or vertical position.

Double protection

The duct heater is equipped with two integrated protections (one with automatic reset and one with manual reset), to prevent overheating in case of a fault in the system.

CB 125-1,2 230V/1 Duct heater #5290

Electrical duct heaterDuct heater with spigot connection for standard spiral circular ducts. Manufactured from Aluzinc-coated sheet steel with a heating element in stainless steel. The CB heater has rubber seals on the connecting spigots. The heater has double integral overheating protection: one with automatic and one with manual reset. Suitable for control by room thermostat or Pulser regulator (additional accessories). 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 position. In a horizontal position, the connection box should be installed facing upwards, or rotated 90° to one side. Installation with the connection box facing downwards is not allowed.
