2.2.2 Essential construction rules

The construction of the corridor is critical for the correct
working of the MAT air curtain. The rules in this section must
be followed carefully.
Rules on geometry
1. The entire corridor must be free of air leaks at all places.
Even small holes or gaps letting air trough will disturb the
working.
2. The side panels must fit narrowly to the air curtain unit.
3. The surface of the side panels must be smooth. Even small
irregularities will disturb the working.
c
Caution:
Follow these rules strictly. Otherwise:
- there will be no effective climate separation, making the
MAT air curtain useless,
- side effects, like mist and precipitation of water and ice,
may occur, causing unhygienic, and possibly dangerous
situations.
Rules on materials
4. The corridor must be thermally insulated at all places.
5. Cold bridges must be avoided.
c
Caution:
Do not leave any part without insulation.
Otherwise, precipitation of ice and water will occur on the
outside, causing unhygienic situations.
