3. EC Fans
4. Custom unit lengths up to 3,000 mm
5. Easy to maintain thanks to the filterless micro-intake grille
6. Various heating media are possible
7. TEKADOOR Electronic Multifunction Control Unit; on-site control is optional

Self-supporting steel/aluminum composite construction with no visible screws, available with a powder-coated finish in any RAL color or in a stainless steel version. Jetflow exhaust nozzle made of aluminum, powder-coated to match the unit’s color. Designer intake grille with a fine-perforated pattern for easy-to-maintain, filterless operation.

DHW: for standard-temperature DHW 70/50°C and low-temperature DHW 60/40°C; other temperatures available upon request.
DX: DX coils brazed under nitrogen for use with heat pumps (heating mode only). High-quality heat exchangers made of copper tubing, with press-fitted, extra-strong aluminum fins.
ELEKTRO: 3-stage 400V heat exchanger, spiral-shaped and corrosion-resistant, with thermal overheating protection and a run-on circuit.

The efficiency of the EC fans used by Tekadoor is >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 installation thanks to rivet nuts (M8) recessed into the top of the unit and optional mounting hardware. In the standard configuration, 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 unit and parallel operation, are accessible from the outside.

Easy-to-maintain cleaning—micro-grille—no need to open the unit; simply vacuum through the intake grille. A bolted and secured access panel (hinged on one side) on the underside of the unit that is easy to open for maintenance work.

Air is discharged through the patented, multi-position Jetflow discharge nozzle (adjustable without tools), which features an adaptive, asymmetrical nozzle cross-section that evenly directs the air stream over a long throw distance. Available in two configurations: with a standard air roller (room-side intake) or with a reversed air roller (door-side intake).

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 optionally be implemented 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.
