The ACHM20 is an automatic door system (wing and frame) where the wing provides for a partial seal with a specially designed guard.

Super-Silent Operation

All versions of the ACHM20 feature super silent operation, thanks to anti-vibration seals, making them ideal for environments where comfort, silence and a warm welcome are indispensable and fundamental requirements.

Certified Airtightness

The rounded guard and the screwless visible heads prevent dust from building up, thereby making the cleaning process far simpler and more reliable. Electrostatic energy that may have accumulated on the moving wings is permanently discharged through the unique moving earth built into the ACHM20. Automatic doors must guarantee freedom of movement in absolute hygiene and safety for all users without coming into manual contact with the actual doors. The ACHM20 accommodates these needs fully.

Intelligent Controls

Built in motion detectors can be added into the automation, and if necessary can be concealed within the head of the door. Consequently this prevents the usual build up of dust on the outside of the safety sensor, a common problem with standard safety sensor installation. The safety sensors also ensure protection not only in the doorway but also in the side opening movement of the wings, preventing accidental impact with unforeseen obstacles. They are indispensable when stretchers and wheelchairs are passing which may not be detected by traditional photocells.
