Air handling units Mechanical performance
The mechanical performance of the Roccheggiani Air Handling Units
have been tested in the TÜV SÜD laboratories (rep. no. 6889) under
the Eurovent Certification program and the units belong to the
following classes:
• Mechanical strength of the casing: D1(M) with maximum
measured deflection 2,6mm/m.
Units can withstand to ±2500 Pa with no permanent deflections.
• Casing Air leakage: L2(M)
• Filter by-pass leakage: F9 - percent leakage < 0,1%
Leakage test according to EN 1886:2008
Positive Pressure
The Air handling unit can be tested upon
Customer request on:
• Airflow volume and Static Pressure
• Vibration
• Leakage
• Noise
• Cooling (Water at 7°C up to 140kW)
• Heating (Water at 80°C up to 500kW)
Due to the following standards:
• EN 13053:2007
• EN 12599:2001
• EN 1886:2007
