Design air curtain
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.
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.
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).
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.
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.
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.
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.
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.
