WING-R EC with a curved design and WING-G EC with a straight design are particularly suitable for curved sliding doors, automatic linear sliding doors as well as for retrofitting to revolving doors. The timeless design and user-friendly technology will satisfy architects, planners, clients and operators in equal measure. WING-R EC and WING-G EC are the ideal solution wherever a door air curtain cannot be installed horizontally due to the particular characteristics of the building, or if vertical installation is preferred for aesthetic reasons. Also ideal for retrofitting.
The height of the unit should be selected individually, depending on the height of the entrance or door. As the Jetflow discharge nozzle runs along the entire length of the unit, the heated air is also blown directly over the floor, where the potential for cold air to enter is the greatest. The patented and multi-adjustable (without tools) Jetflow discharge nozzle – with its adaptive, asymmetrical nozzle cross-section – is characterised by a smooth air stream and a large throw distance.
Self-supporting steel/aluminium composite construction with a curved or straight design. Screws are not visible. Available with powder coating in a selection of RAL colours, or as a stainless steel version. Aluminium Jetflow discharge nozzle, powder coated to match the unit. Attractive intake grille with micro grille behind it (used as an intake filter) for filterless operation.
Heat exchangers for different heating media
LPHW: For normal temperature LPHW 70/50 °C and lowtemperature LPHW 60/40 °C, other temperatures available on request.
High-quality heat exchanger made from copper tubes, with pressed-on, extra-strong aluminium fins.
ELECTRO: 3-stage heat exchanger 400 V, spiral form, corrosion resistant, with thermal overheating protection and switch-off delay.
The efficiency of the EC fans used by TEKADOOR is > 90% under partial load operation. This is 30–35% higher than for conventional AC fans. This does not just increase the efficiency, but also reduces the operating costs. The individually-driven EC fans with integrated motor protection can intake air in both directions. They have vibration-free bearings and are controlled using a PWM signal (pulse width modulation).
They do not just comply with Directive ErP, but actually exceed this standard.
Trouble-free mounting directly on the finished flooring, via holes in the floor plate (not visible once installation complete). The floor plate has appropriate recesses for invisible energy supply from below. Optional: Power supply is also possible from above.
Easy to clean (micro grille) without opening the unit by simply vacuuming the intake grille. Discreet inspection panel for maintenance work, hinged on one side – easy to access from the room side.
Electronic TEKADOOR GTC EC control unit, multifunctional with touch display, including an optional ModBus interface
A GTC 1 EC control unit is used as standard for models with LPHW heating. A GTC E EC control unit is used for models with electrical heating. The units come with 20 m preassembled and shielded data cable. The GTC 1 EC 5-stage control unit includes the ability to switch from manual to automatic and from summer mode to winter mode as standard. A solenoid valve of up to 2.5 A can be connected as an option for the winter mode. With the standard GTC E EC control unit, the airflow can be selected manually in 5 stages and the heating capacity – depending on the fan level – can be selected manually in 3 stages. Each control unit includes a manual to automatic mode switch and a potential-free contact for enabling via any on-site BMS or BEMS. A choice of 5-stage or stepless fan operation is offered as standard.
A maximum of 10 units can be connected in parallel.
Floor mounted vertical unit
Heating connections – flow and return – for easy connection to the on-site heating system.
– Connections: Either from below or above, invisible within the door air curtain.
Data cable connection/interface
Standard connection options for the data cable and an optional solenoid valve or thermo-electric shut-off valve within the unit. Simple plug and play of the data cable. Control:
Input for the data cable to the control unit. Auxiliary:
Output for parallel operation with other units.
Simple electrical connection of the power supply 230 V/50 Hz thanks to the internal connection box. Exception:
Electrical units with a heating capacity greater than 22.5 kW.
Jetflow discharge nozzle (WING-R)
Jetflow discharge nozzle with adaptive, asymmetrical nozzle cross-section. The special design of this patented discharge nozzle permits stepless variation of the discharge angle combined with a longer guided, smooth air stream with optimum throw distance.
Wing-R EC & Wing-G EC
Thermostatic straight-way valve
(Setting range + 20 °C to + 35 °C) limits the discharge temperature (constant supply air temperature limitation). Also available as a 3-way valve.
Door contact solenoid switch
In automatic mode switches on the door air curtain in the preselected stages.
Thermo-electric shut-off valve
230 V / 50 Hz, normally closed. On-site installation in the heating flow. Actuation via the summer/winter circuit.
Summer function – closed.
Winter function – open.
Frost protection thermostat
For monitoring LPHW heat exchangers exposed to the risk of frost. As soon as the temperature falls below +7 °C, the fans are switched off and an optional solenoid valve is opened.
Wing-R EC & Wing-G EC
Opens or closes the heating water circuit in the summer/winter setting of the control unit, to close the heating water circuit during summer operation or when the air curtain is not working (normally closed). Caution: If solenoid valves or thermoelectric shut-off valves are used, it is expressly recommended to install a frost protection thermostat (automatically actuated) and a strainer.
Electronic control valve
Electronic valve with 0-10V impulse and blow-out temperature sensor completely installed and wired. In combination with the GTC 2 control, a preselected blow-out temperature is kept constant.
Founded in 1981 in Leichlingen/Rheinland, Germany, today we are one of the leading providers of door air curtains in Europe. Due to constant growth, in 2005 we moved our production location from Leichlingen to the neighbouring town of Langenfeld. This is also the location of our current extended production and administration building, which we moved to in 2010. From here we sell our “Made in Germany” products throughout the world. Securing the future of our company and thus safeguarding local jobs as well is the reason why we have always remained faithful to our Rhine region.
