r-tec Automatic Door Systems

Overview

r-tec automatic door systems are mechatronic systems that provide automatic open-close at high pedestrian entrances such as shopping centres, hospitals, office lobbies, banks, hotels and airports. They are adapted to different site scenarios with three chassis options (standard, telescopic, hermetic) and four door types (double-leaf sliding, single-leaf sliding, telescopic, revolving). In all products, a single control unit — R2 — is used; our dealers manage the same spare-parts stock even when the door types differ.

Chassis options

Standard chassis — Used in single-leaf or double-leaf sliding applications. Common in standard pedestrian transits such as office lobbies, shopping centre entrance doors, bank branches.

Telescopic chassis — Provides wider net transit opening with 4 door panels hidden behind each other. Preferred at entrances with limited wall distance, where a wide opening requirement exists.

Hermetic chassis — For applications where ventilation leakage is not acceptable such as hospital operating rooms, clean rooms, laboratories and food production facilities. Full sealing with side and top seals + EN class insulation. The highest engineering segment in the automatic door portfolio.

Four door types

Type	Max. leaf weight	Opening speed	Typical application
Double-leaf sliding	120 + 120 kg	180 cm/s	Shopping centre, hospital, office main entrance
Single-leaf sliding	150 kg	90 cm/s	Bank branch, small shop, personal entrance
Telescopic (4-leaf)	4 × 60 kg	180 cm/s	Narrow wall, wide transit required
Revolving	(Per model)	(Per model)	Hotel lobby, premium commercial entrance

R2 control unit

R2 is a dedicated control board designed only for automatic door applications. It takes 230 VAC mains voltage and drives the door motor with a 24 VDC output. Highlight features:

• 23 parameters — Opening/closing deceleration distance, hold-open time, operating speed, closing-speed ratio, opening ramp, partial opening percentage, brake force, etc. Fine adjustment for every site condition.
• 12 fault codes — o1–o9, 10, 11, St — Reports motor thermal, switch, encoder, photocell, current protection, system reset and other fault conditions with separate codes.
• 5 operation modes — Selector switch transitions:
  1. Hold open — Door continuously open, for keeping the entrance fully open at night.
  2. Partial opening — Only 40-60% opening to limit air circulation (air-conditioned environments).
  3. One-way — Only inward/outward, single-direction safety strip permission.
  4. Automatic (standard) — Normal operation triggered by photocell/sensor.
  5. Hold closed — Door continuously closed, after-hours lock mode.

Speed and safety

The opening speed of 90 cm/s for single-leaf and 180 cm/s for double-leaf is at the top of its class. The closing speed is 70% of the opening speed; the slower closing movement is intended to reduce trapping risk. The hold-open time can be adjusted between 0 and 90 seconds (for busy / quiet hour scenarios).

Archived document records and evidence boundary

TÜV Austria record 16-PS-0009-TAT-21-MAD-2479 identifies the product as AUTOMATIC DOOR and the type/model scope as r-tec, open, con-tech. The document was renewed on 12 February 2021 and expired on 12 February 2022. This archived record does not separately name sliding, telescopic or revolving variants, the R2 control unit, or the four door types on this page as its scope.

Domestic Product record 20221188100201, issued through SATSO / TOBB, identifies the product only as AUTOMATIC DOOR and states a 100% domestic contribution rate. It was valid from 8 September 2022 to 8 September 2023 and is now an archive record; it gives no separate scope or cost breakdown for the motor, control board, mechanical assembly or electronic components.

Neither historical record is evidence of a current certificate or current production ratio. The proposed model, control unit, equipment and current conformity file are verified separately for each project.

Target projects

• Shopping centre and plaza main entrance doors
• Hospital emergency service and operating room (hermetic chassis)
• Bank branch, currency exchange office, jeweller (secured pedestrian access)
• Hotel lobby and restaurant main entrance (revolving door)
• Airport terminal pedestrian transits
• Office towers and plaza lobby
• Pharmacy, market and retail store entrance doors

Service and spare parts

For the R2 control board + 24 V DC motor + 4 door type chassis, 20 different spare parts are supplied from stock through the manufacturer channel. Installation and maintenance are carried out by the authorised technical team running the project; a periodic maintenance plan is recommended for heavy-use applications (airport, shopping centre).
