Product description
Cabinet

The cabinet is made of steel sheet laminated with a layer of plastic without visible screw or rivet joints. The cabinet is RAL 9016 white, the decorative intake grille is powder coated in RAL 9006, the exhaust opening is fitted with moulded slats and an anodised aluminium frame in a natural shade. On request, it can be supplied in any RAL shade or stainless steel. The enclosures are available in several types depending on the mounting method and the desired shading effect. Extensions or a decorative frame are available for ceiling mounting. The water heater screens should be ordered with a regenerative filter. No filter is supplied for screens with an electric heater.

Fans

High performance double-sided suction radial fans, five-speed or three-speed (for curtains with electric heater) motors with thermocontacts are used. Fans with EC motors are also available on request to provide infinitely variable speed control. IP20 protection.

Heater

Each heater is wired in three sections, the individual stages can be manually set on the controller.

Electric connection

The cable glands are located at the right end of the cabinet from the top. The atypical right-hand version is mirrored.

Regulation

Clones with an electric heater up to 30 kW are controlled by the UBT 3E / UBT 3E LCD controller. The controller is used to manually or automatically start the orifice, adjust the speed in three stages, control up to 6 orifices in different operating modes, connect an external (door) contact and a room thermostat and set the time up to 10 minutes. If a controller is not prescribed, the aperture is supplied without a control circuit. The heater fans and heating rods are brought out to the terminal block only.

Frost protection

When using the curtain in an AWE installation, the water heaters must be protected against freezing. An antifreeze thermostat, which is mounted and wired directly at the factory, is used for this purpose. The frost protection function is provided by the EBT 5 / UBT 5 LCD controller.
