DTH40 Convenient combination of detachable machine hatch with swing door

Detachable machine hatch is used for a large opening that is used only several times or once a year. It is a blended door convenient for the following cases: a door for entrance and exit of people can only be installed at a certain place due to the room layout, and a door for entrance and exit of people needs to be installed at a certain place. A swing door is attached either on the right end or left end for a structural reason. The swing door can be removed from the hinge if it is opened more than 90 degrees. Therefore, the swing door can also be positioned as a machine hatch, resulting in securing a large opening.

  • Superb airtightness as it is designed based on the structure of DR40 that satisfies the A-4 grade of airtightness performance. *
    (In the case of four-side frame cremone specification)
  • Both the swing door and detachable machine hatch are very light due to the combination of aluminum frames and styrene foam (phenol foam in case of heat-insulating incombustible specification) inside the door.
  • Various options are available, such as window and louver.
  • Fully custom-fabricated in the unit of one millimeter.

* Airtightness performance test has not been conducted for DTH40 as a single unit.
