The EST energy saver door is a high speed door for use in freezer rooms.


As one of the first doors of its kind, it can be installed and operated on the heated side or the cold side down to -30°Celsius . It also has a self-supporting structure so that the door can be installed completely separately from the walls.  The short opening and closing times mean that unnecessary waiting for internal traffic is avoided and energy loss is minimised.


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

An integrated emergency opening function complying with ASR 1.7 ensures that workers cannot be locked in the freezer area in the event of power failure.
