KTV 3/KTV 4 Revolving Doors

Door characteristics

A revolving door limits noise, dirt, dust and drafts transferring from outside to the inside of the building. KTV 3/4 entrance systems are exceptional at this having a “Twin-Brush” double row of sealing brushes on the door wings against the drum wall, ceiling and floor that assist in maintaining the internal building climate.   Consequently, KTV3/4 revolving doors are an excellent aid for controlling heating and air-conditioning cost.

Operating Modes

KTV 3 and KTV 4 revolving doors are available in various operating modes. 

"M" -  Manual operation with or without speed limiter 
"P" - Automatic door with automatic positioning control (low energy)
"S" -  Automatic door with servomatic control (low energy)
"A"  - Fully automatic door (full energy)

The KTV FLEX drive can be configured to any of the operating modes. The door's mode of operation can even be adjusted afterwards - without having to replace the motor or controller.

3 Wing v 4 Wing door

3-wing doors provide more space in the individual segments. The lower weight also reduces the effort needed to enter manual and power-assisted doors. In addition, greater clear passage heights are practicable, which makes particularly streamlined door designs possible. 

4-wing doors offer wider entrance and exit areas to facilitate simultaneous entering and exiting of the building. With a higher number of seals toward the posts, such doors also provide better protection against draughts, noise and external climatic influences when in the rest position.
