Automatic slide doors

System MB-78 EI DPA is used for fire partitions with single or double-leaf automatic slide doors with fire resistance class EI15 or EI30. It relies on a popular system MB-78EI which has been used in numerous realisations and which provides the majority of components. It is based on three-chamber aluminium profiles of structural depth equal to 78 mm with thermal break of 34 mm. Internal chambers of profiles as well as insulation spaces between the profiles are filled with fire insulation elements, while additional insulation elements and expanding sealing tapes are applied on external surfaces. This system allows for the use of shaft-mounted muntins. Structure performance technology is analogous to the base system. In parallel to MB-78EI fire resistance of doors and walls with doors is maintained both in case of fire impact from the outside and from the inside.

In structures MB-78 EI DPA can use drives of renowned manufacturers, adapted to carry adequately large loads. Slide doors’ drive can be installed on the system wall and on the wall.

MAXIMUM STRUCTURAL DIMENSIONS IN THE PASSAGE CLEARANCE ARE:

• height of single-leaf and double-leaf doors: up to 2 450 mm.
• width of single-leaf door: up to 1 100 mm.
• width of double-leaf door: up to 2 125 mm.

System MB-78EI DPA had been awarded with Technical Approval by the Building Research Institute number AT-15-6006/2012
