TECHNICAL DATA - 2008 page 5 Design Frame members: Specially designed, enclosed frame members, made of 1.5 mm thick or 1.8 mm thick (for unit sizes 60–84) sheet steel, available in aluminiumzinc plated or stainless version. Corner pieces: Rounded corner pieces cast in one piece, with two tapped holes in each leg. The frame members and corner pieces are joined together by means of screws. Panels: Closed, double-skin sheet steel with 50 mm thick insulation sandwiched between the sheet steel. The skin consists of 0.7 or 1.0 mm thick galvanized or stainless sheet steel. Incombustible 50 kg/m3...

TECHNICAL DATA - 2008 page 6 Casing – design and properties The casing framework consists of box-section frame members joined together sturdy corner pieces. The entire arrangement forms a strong and stable framework. The panels and inspection doors are of double-skin construction, with 50 mm thick mineral wool insulation sandwiched between sheet steel. The panels can be removed from the unit. In all unit sizes, the inspection doors are hung on adjustable hinges and are equipped with mechanically secured sealing strips. The inspection doors are also available with door locks. The sandwich...

TECHNICAL DATA - 2008 page 7 Casing – design and properties Doors are fitted with durable rubber seals and are mounted on hinges. Samtliga dörrar förses med låsbara handtag. The insulation factor kb (dimensionless, cold bridge factor) is defined by the following formula: kb = (ts - ti) / (te - ti) where Anti-condensation insulation of the casing ti = Average temperature of the air in the unit casing te = Average ambient temperature Heat losses from the casing The heat transfer coefficient of the unit casing is given in W/(m2°C) when the temperature differential between the inside and...

TECHNICAL DATA - 2008 page 8 Casing – design and properties CEN-standard prEN 1886 classifies leakage rates for air handling units as follows. CEN-standard prEN 1886 classifies casing strength as follows: Casing tightness Leakage class Suction -400 Pa Leakage flow max l/s, m2 Pressure +700 Pa Leakage flow max l/s, m2 Highest rec. filter class Casing strength Casing class The leakage flow rate for a unit only subjected to suction must not exceed the above tabulated figures at -400 Pa. The leakage flow rate for a unit only subjected to pressure must not exceed the above tabulated figures at...

TECHNICAL DATA - 2008 page 9 Casing – design and properties The outdoor version of the unit is basically the same as the indoor version, and the technical specifications are the same. The outside of the casing is sealed between panels and frame with permanently elastic sealing compound to prevent moisture from entering the unit. Intake sections with grilles designed for an effective barrier against rain and snow are available. The unit is equipped with a curved EUBZ-01 roof to ensure good water run-off. The roof projects beyond the edge of the unit casing and has a turned-down edge. Even in...
