ApplicationsRondell EC is "The" door air curtain for revolving doors. The unit is delivered complete with a discharge duct and support, including discharge fins, in three installation variants. These variants can be installed on top of, integrated into or in front of the door.

Special designWith every rotation, revolving doors bring in cold external air. Particularly for highly-frequented doors, a "cold patch" forms on the floor directly behind the revolving door. By using our door air curtain system "TEKADOOR Rondell EC", with an integrated air outlet especially adapted to the door radius, the spread of cold air is prevented and the recirculating air is warmed up to room temperature. This results in a pleasant indoor climate in the entry area. The design of the Rondell EC air curtain is always individual, corresponding to the existing or planned revolving door, whereby the discharge support with integrated fins is adapted to the door radius.

The housingThis consists of an industrially-galvanised self-supporting sheet steel housing with intake grille and duct connection flange, discharge duct with support and integrated discharge fins. All the visible parts can be powder coated in standard RAL colours, depending on the wishes of the client. Fascia covers can be manufactured in RAL colours or, optionally, in stainless steel.Inspection panel optionally from above or below.

Heating mediaHeat exchangers for different heating mediaLPHW: 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 fansThe 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.

MountingSimple mounting thanks to the incorporated M8 rivet nuts on the top or at the sides of the unit (4 on each side).Accessories for mounting on the revolving door (top mounted unit) consist of two rectangular tubes and a set of bolts.

Maintenance Easy to clean without opening the unit by simply vacuuming the intake grille. The inspection panel can be removed completely for maintenance work.

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 – de-pending 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.

CONTROL UNIT GTC 1 ECMultilingual, menu-driven electronic control unit for TEKADOOR air curtains with LPHW heating and energy-saving EC fans. A standard feature of the control unit with touch display is a choice between 5-stage or stageless fan control, which can be selected individually by the operator. The relevant operating modes and symbols are arranged clearly on the colour display. The date, time and room temperature are shown as standard. The room temperature is monitored via an internal temperature sensor in the control unit as standard.

An easy-to-navigate menu offers a selection of different operating modes:Hand – manual operationAuto AS – automatic operation via cool down protectionAuto RT – automatic operation via room temperatureAuto TK – automatic operation via door contactAuto Kombi – option to combine all individual automatic modes

An enabling contact and potential-free operation and malfunction signals are provided for control via an on-site BMS or BEMS. Errors and faults are displayed with a red „warning“ sign. By coding the control boards differently, up to 10 door air curtains can also be operated in parallel with 1 control unit, using the Master/Slave principle. The control board is preinstalled in the door air curtain unit and 20 m of preassembled data cable (connection between the door air curtain and control unit) are included as standard.

1. Rated operation based on operating point (see above), discharge temperature control recommended. 2. Measured at a lateral distance of 3 m. Sound pressure level may very depending on surrounding conditions.

[DX-H available on request (only heating mode possible)]

A well-balanced pressure ratio is one of the prerequisites for perfect function.
