When there is only few space or not space at all to the side, the sliding hatch EFA-HVS-CR is used which opens and closes vertically. The door leaf closes flush with the guides and closes hermetically. Typical areas of use of the EFA-HVS-CR are logistics, materials-handling technology as well as material and lift shafts in controlled zones. The door leaf of the hermetic vertical sliding hatch is also available as stainless steel finish, as option.
