The air handling unit is EUROVENT (AKS 600 – AKS 2535) certified and tested in EN 1751: 1988, DIN 1946 Part 4: 2008, DIN EN ISO 5167 Standards. Max DEFLECTION for Body Mechanical Strength according to EN 1886: Positive and negative pressure D1(M) according to EN 1886, Maximum Leakage – for 400 Pascal: L1, for +700 Pascal: L1, Filter Bypass Leakage: F9, Thermal conductivity resistance: T3, Thermal Bridge: TB2 class. The inner and outer sheets of the Body Panels are made of dipped galvanized steel, and the outer sheet is manufactured with RAL 9002 polyester-based powder paint. All panels and doors are double-walled; Sheet thickness minimum outer sheet 0.9 mm. inner sheet is 0.8 mm. All interior surfaces of the body are completely smooth and smooth, suitable for washing and wiping, and no welded joints are made in any way. 50 mm as insulation material between inner sheet and outer sheet. Thickness of Rockwool is used. The assembly and disassembly of the switchboard panels is carried out entirely externally. Switchboard cell connections are made through external connection elements. There are long-lasting information labels on the switchboard cassette that contain the plant’s technical information and also identify the cells in each cell, are not easily removed, are resistant to moisture and water. If the switchboard is shipped to the site as more than one cell, there will be information labels and cell connection apparatus on the switchboard showing which cell is which cell of the switchboard, in order to ensure easy assembly of the cells.
