3. Installation Options: Free-hanging, flush with the ceiling as a cassette, recessed installation in a false ceiling with a slide-in fitting, floor-standing unit available upon request
4. Easy to maintain thanks to the filterless micro-intake grille
5. Aerodynamically Optimized Discharge Fin
6. TEKADOOR Electronic Multifunction Control Unit; on-site control is optional

The efficiency of the EC fans used by Tekadoor is greater than 90% under partial load, which is approximately 30–35% higher than that of conventional AC fans. This not only increases efficiency but also reduces operating costs. The individually driven EC fans with integrated motor protection feature double-sided intake, are mounted on vibration-free bearings, and are controlled by a PWM (pulse-width modulation) signal. They not only comply with the ErP Directive but actually exceed this standard.

Easy-to-maintain cleaning of the micro-grille without opening the unit—simply vacuum the intake grille. A blind-screwed and secured access panel (hinged on one side) on the underside of the unit—easy to open.

Self-supporting, powder-coated sheet steel housing with no visible screws; standard finish in RAL 9016 (traffic white)—other colors available. Inspection opening from below, blind-screwed behind the intake grille. Intake grille in the same color as the unit, consisting of a perforated sheet with a micro-grille behind it (serves as an intake filter) for easy maintenance. Exhaust grille with continuously adjustable exhaust louver (natural anodized) for optimal airflow.

Easy installation thanks to rivet nuts (M8) recessed into the top of the unit and optionally available mounting hardware. In the standard version, the unit does not need to be opened for electrical connection. Terminal blocks for the power supply, as well as the connectors for the control panel and parallel operation, are accessible from the outside.

TEKADOOR CAT Electronic Multifunctional Control System

• A 20-meter pre-assembled, shielded data cable is included as standard with devices equipped with PWW and electric heating.
• The 5-stage CAT control system includes a manual/automatic mode and a summer/winter switch as standard features.
• A weekly timer with a timer function can be implemented optionally using enable contacts.
• For winter operation, a solenoid valve rated up to 2.5 A can be connected (optional).
• With the CAT control system, the airflow can be manually adjusted in 5 steps, and the heating output—which, in the case of electric heating, depends on the fan speed—can be manually adjusted in 3 steps.
• An enable contact and potential-free operating and fault signals are available for control via a customer-supplied BMS or DDC.
• Up to 10 devices can be connected in parallel in a master-slave configuration.
• On-site control via a ModBus interface is also possible.
