Ellipse EC

Design air curtain

INDIVIDUAL
INNOVATIVE
ENERGY-SAVING



  • Applications

    Ellipse EC is recommended when not only the function is important in the configuration of the entry area, but the appearance as well. The free-hanging, installation-ready unit with a modern, elliptical shape fits with the respective design of the door area thanks to a choice of powder-coated steel or stainless steel housings.

  • Special design

    Discharge is via the patented, multi-adjustable Jetflow discharge nozzle (adjustable without tools), with an adaptive, asymmetrical nozzle cross-section. This guides the air stream smoothly with a large throw distance. Versions are available with a standard air roll (intake on the room side) or with a reversed air roll (intake on the door side).

  • The housing

    Self-supporting steel/aluminium composite construction. Screws are not visible. Available with powder-coating in a selection of RAL colours, or alternatively as a stainless steel version. Aluminium Jetflow discharge nozzle, powder-coated to match the unit. Attractive intake grille with fine hole pattern for service-friendly, filterless operation

  • Heating media

    Heat exchangers for different heating media
    LPHW: for normal temperature LPHW 70/50°C and low-temperature LPHW 60/40°C, other temperatures available on request.
    DX: DX register soldered under nitrogen for operation with heat pumps (only heating modus possible). High-quality heat exchanger made from copper tubes, with pressed-on, extra-strong aluminium fins.
    ELECTRO: 3-stage heat exchanger 400V, spiral form, corrosion resistant, with thermal overheating protection and switch-off delay.

  • EC fans

    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) – and with 0-10 V for the DX. They do not just comply with Directive ErP, but actually exceed this standard.

  • Mounting

    Simple mounting thanks to the rivet nuts (M8) incorporated on the upper side of the unit and optionally-available assembly materials. In the standard version, the unit does not need to be opened for electrical connection. Connection terminals for the voltage supply, as well as the connectors for the control unit and parallel operation can be accessed from the outside.

  • Maintenance

    Easy to clean – micro grille – without opening the unit by simply vacuuming the intake grille.
    Screwed and secured inspection panel on the underside of the unit (hinges on one side) – easy to open.

  • Control

    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.

Details



Connections

Connections

Heating connections – flow and return – on top of the unit as standard for easy connection to the on-site heating system. (Internal thread dimensions depend on the model) Optionally, the connections can also be located at the side.



Connection box (LPHW)

Connection box (LPHW)

Simple electrical connection via connection box (voltage supply 230 V/50Hz on the top of the unit); connection can optionally also be located at the side.

Exception:
Electrical units with a heating capacity greater than 22.5 kW.



Data cable connection / interface

Data cable connection/interface

Simple, standard plug and play connection of the data cable and an optional solenoid valve on the top side of the unit. The connection can be offset on request.

Control:
Input for the data cable to the control unit.

Auxiliary:
Output for parallel operation with other units.



Jetflow discharge nozzle

Jetflow discharge nozzle

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.

Optional accessories



Thermostatic straightway valve

Thermostatic straightway valve

(Setting range + 20 °C to + 35 °C) limits the discharge temperature (constant supply air temperature limitation). Also available as a 3-way valve.



Ceiling attachment set

Ceiling attachment set

For problem-free, vibration-free ceiling attachment, consisting of M8 threaded rods, up to 1000 mm length, vibration dampers, turn-buckles and counter nuts.



Door contact solenoid switch

Door contact solenoid switch

In automatic mode switches on the door air curtain in the preselected stages.



Frost protection thermostat

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.



Solenoid valve

Solenoid valve

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 thermo-electric shut-off valves are used, it is expressly recommended to install a frost protection thermostat (automatically actuated) and a strainer.



Raumthermostat

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.



Thermo-electric shut-off valve

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.

Free-hanging installation



SLW suspension

SLW suspension

Connection-ready, free-hanging door air curtain unit for visible installation with standard air roll (SLW). The ambient air intake is on the room side and the air discharge directly at the door. Different-sized air rolls are installed depending on the size of the room. The standard air roll is selected for small to medium door widths and shops at street level with a balanced pressure ratio.



ULW suspension

ULW suspension

Connection-ready, free-hanging door air curtain unit for visible installation with reversed air roll (ULW). The mixed air intake is by the door and the air discharge on the room side. A frost protection thermostat is absolutely essential for the ULW version. This unit is used for unfavourable store locations and difficult entry situations (multi-level, large entry area).
The reversed air roll counteracts the cold external air. The air movement in the entry area is reduced and the shielding performance increased.



Installation variants



Free-hanging


Connection-ready, free-hanging door air curtain unit for visible installation directly above the door. For the SLW version, the ambient air intake is at the front, on the room side. For the ULW version it is from the door side.
