CB

Duct heater with integral control equipmentDuct heater with spigot connection for standard spiral circular ducts. Manufactured from Aluzinc-coated sheet steel with a heating element in stainless steel. The CBM has rubber seals on the connecting spigots. The temperature is set on the cover of the duct heater. The heater has double integral overheating protection: one with automatic and one with manual reset. The unit is controlled by an integral electronic temperature regulator, using so-called time-proportional Pulse/Pause technology. This provides extremely precise temperature control. As a thyristor is used for adjusting the temperature, the unit has no moving parts. This means that it is silent and not susceptible to wear and tear. Terminals for interlocking the heater, via a pressure- and airflow guard are available in the terminal box. 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 CBM 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.All CBMs are delivered with duct sensor TG-K330 (0-30°C) as standard.
