Aliga-Tor GmbH

ALIGA-TOR save your energy


Vertical rapid action door for deep-freeze areas with temperatures as low as -30°C.

The ALIGA-EST is one of the first doors ever to be able to be installed and operated on both the warm and cold sides at temperatures as low as −30°Celsius. In addition, the self-supporting construction ensures that the door can be installed completely independently of the wall conditions. 

The short opening and closing speeds reduce unnecessary waiting times on the internal traffic routes and minimise energy losses.

There are no visible cables on the entire door, and all components are integrated into the panel construction.

Optionally, an integrated emergency opening function in accordance with ASR 1.7 ensures that no employee is locked in the freezer area even in the event of a power failure. (Please specify when ordering.)
