Colum EC

Design air curtain

INDIVIDUAL
INNOVATIVE
ENERGY-SAVING



  • Applications

    With its suspended and standing versions, Colum EC is particularly suited to the visible parts of modern entry areas and, thanks to its rounded design and low maintenance operation, will satisfy architects, planners, clients and operators. The floor mounted vertical unit is particularly suited to revolving doors, since the heated airflow is discharged directly all the way down to the floor level without losing heat, thus preventing the formation of a "cold patch". The choice of standard RAL powder coatings or the stainless steel housing fit superbly in existing entry areas. Colum EC is used in hotels, banks, flagship stores, shopping malls, airports and public buildings.

  • Special design

    Colum EC is available in variable housing lengths up to 3 m. It is simple to retrofit the floor mounted vertical unit in existing door systems.

  • The housing

    Self-supporting steel-composite construction in a cylindrical shape with split sheet steel or stainless steel housing (polished to grain size 240) in a round-rolled design.
    Screws and rivets are not visible.
    Powder coated intake grille in the same colours as the unit or stainless steel version, consisting of a perforated plate with micro grille behind it for easy maintenance application. Aluminium discharge grille for an infinitely adjustable, unidirectional air stream Invisible energy connections for the floor mounted vertical unit (discreetly bolted in place via holes in the floor plate).

  • 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

    Floor mounted vertical unit: Problem-free mounting via holes in the floor plate directly on the finished flooring. The floor plate has appropriate recesses for invisible energy supply from below. Optional: Power supply is also possible from above. Suspended version: simple mounting thanks to the M8 rivet nuts incorporated on the upper side of the unit as well as optionally-available assembly materials.

  • Maintenance

    Easy to clean (micro grille) without opening the unit by simply vacuuming the intake grille. The intake grille must be removed before the revision panel can be opened. To do this, a cross-headed screw at the upper end of the intake grille must be removed. Then the intake grille can be taken out of the lower frame.

  • 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

Floor mounted vertical unit

Heating connections – flow and return – for easy connection to the on-site heating system.

- Connections for the floor mounted vertical unit: either from below or above, invisible within the door air curtain.

- for the suspended version: on the upper side of the unit (or optionally from the side)



Connection box

Connection box

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.



Data cable connection / interface

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.



Discharge fins

Discharge fins

Discharge grille with aluminium fins (drop profile), depending on the model available in designs with double or multiple fins, for an infinitely adjustable, unidirectional air stream. During the heating period, the fins should be tilted outwards by 10 to 15 degrees to prevent cold air coming in from the outside. In contrast, during operation in the summer, the fins are tilted inwards, so that the cooled indoor air cannot escape.

Optional accessories



Thermostatic straight-way valve

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.



Thermo-electric shut-off valve

Thermo-electric shut-off valve

230V/50 Hz, normally closed. On-site installation in the heating flow. Actuation via the summer/winter circuit. Summer function – closed. Winter function – open.



Door contact solenoid switch

Door contact solenoid switch

In automatic mode switches on the door air curtain in the preselected stage – in conjunction with GTM 2 EC, GTM 3 EC and GTM 2 E EC.



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 thermoelectric 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.
