Overhead door NA – Sophisticated technology that creates space!

Innovative door system

The non-swinging overhead door NA, developed by Käuferle and proven over many years, is the ideal door solution for all collective garages encountering spatial difficulties upon entry and exit.

This innovative and patented door type unites all the benefits that were previously found in different door systems. It does not swing beyond the door level during opening and closing, it is particularly hard wearing and quiet due to an intelligent lightweight aluminium construction and also offers almost unlimited installation and design options.

 

 

Non-swinging fitting

The fitting consists of vertical and horizontal running rails, torsion springs, deflection pulleys and polyamide ball bearing mounted rollers. A non-swinging construction therefore offers specific advantages, particularly in the confined space in collective garages’ entry area.

Advantages

  • Non-swinging, therefore space-saving
  • Finger trapping protection by means of a circumferential rubber lip
  • Minimum loss of space due to optimised installation dimensions particularly low lintel requirement
  • Hard wearing due to an intelligent lightweight aluminium construction and a low number of movable parts
  • Quiet and with a long service life due to a drive system with soft-start and soft-stop function
  • Freedom of design due to flexible frame rung construction
  • Easy and fast emergency operation function in case of a power failure due to spring-loaded weight compensation
  • Identical flap door or side door possible
  • Customised production
  • Colour versatility: Coverings can be coated in all colours
  • Tested acc. to DIN EN 13241-1 and bearing the CE symbol

Dimensions

 Door frame opening min. 2 500 x 2 150 (WxH)
 Door frame opening max. 6 000 x 2 500 (WxH)
If the frame height is greater than 2 500 mm, then installing a fixed panel above the door will be the standard.

DLH = Clear passage height.

Clear passage dimensions are specified in the building regulations. The reduction of the clear building dimensions due to the installation of doors must be taken into account during planning. The clear passage height is reduced by approx. 60 mm if a flap door is installed.

Components

Drive K 120 RV/GV
For overhead door A (swinging) and overhead door NA perfect (non-swinging). Quiet ceiling-mounted traction drive 230 volt with toothed belt and adjustable push rod, with soft-start and soft-stop function, electronic power cut-off and integrated radio receiver, incl. emergency-stop button in the vicinity of the door. Safeguarding of the main closing edges by means of an opto-sensor strip.

Drive KFU 125 RV / GV for overhead door NA perfect
Quiet and robust ceiling-mounted traction drive, 230 volt with frequency converter, transverse steel roller chain, soft-start and soft-stop function, incl. emergency-stop button in the vicinity of the door, safeguarding of the main closing edges by means of an opto-sensor strip.

Control unit for collective garages
KÄUFERLE offers the standard control unit type RV with red pre-warning phase. As an alternative, control unit type GV can be used upon request for two-way lanes. Both control units were especially developed for the operation of door systems in collective garages.

Both control units contain a light disconnection function and the testing of the safety terminal strip and a reversing function, which automatically reverses the travel direction of the door wing element upon contact with an obstacle, thus releasing the obstacle. All of our control units offer potential-free contact to connect building technology services such as BUS or alarm systems.

Radio control
Radio control as a single- or multiple-channel control unit 40/433 MHz, freely codable, consisting of a radio receiver and any number of hand transmitter.

TYPE RV door control unit with red lights
With automatic door closure and adjustable red pre-warning phase.
By triggering a contact, the opening procedure of the door is initiated and the red lights on both sides illuminate. When the door is fully open, the lights go out. After expiration of a time phase the lights switch to red again and the closing of the door begins after a brief pre-warning time. When the door is closed, the lights go out. All time intervals are programmable.

TYP GV door control unit with red/green lights
With automatic close function in case of oncoming traffic.
By triggering a contact, the opening procedure of the door is initiated and the red lights illuminate until the door is fully open. After this, the lights switch over to green for one direction, thus enabling passage. After expiration of a time phase the lights revert to red and the closing of the door begins after a brief delay time. The lights for the opposite direction are red during the entire procedure. The lane is blocked. When the door is closed, the lights go out. All time intervals are programmable.

All of our control units offer potential-free contact to connect building technology services such as BUS or alarm systems.

Key-operated switch column
Galvanised and in DB 703 powder-coated, consisting of a hollow steel section an integrated key-operated switch with an aluminium cover plate, prepared for profile cylinders (semi-cylinders 10/30). Foundation size: 300 x 260 mm x frost depth.

Key-operated switch
Key-operated switch consisting of an aluminium housing and an integrated key-operated switch with aluminium cover plate, prepared for profile cylinders (semi-cylinders 10/30).

Ceiling-mounted traction switch
Pull-cord with pull chain for door operation upon exit.

Day and week timer
The door opening times can be freely programmed using the timer. The door closes automatically after expiration of the selected and set time.

Flasher switch
Door operation takes place via the flasher switch.

Induction impulse transmitter
The impulse transmitter consists of a loop detector and a loop cable, protection type IP 65. When crossed by a vehicle, the loop installed in the lane releases the contact to open the door. Closure takes place automatically after expiration of the set time phase.

Reflection light barrier as a safety device
It serves to safeguard the swing area of the door wing element and is required since the coming into force of DIN EN 12 435 for power-operated door systems in automatic operation.

Doors
Doors can be easily integrated as flap doors into the door wing element of overhead doors or can be positioned next to the door wing element as side doors. The steel cables are optimally protected against corrosion by galvanising and partly by additional coating, the aluminium sections by anodising or powder-coating.

New: Flap doors can also be fitted with a concealed hinge and thus integrated into the door leaf ensuring that they are invisible from the outside.
