For revolving and curved sliding doors
Rondell 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.
With 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.
This 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.

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