Powerfulperformanceandguaranteedquality
Systemair participates in platforms geared to develop and
maintain European and international air handling standards.
The air handling units produced by Systemair meet these
standards.Bothunitsdeliverhighlevelperformancein
theareaofhygieneandsustainabilityqualications.Two
European standards have been formulated that describe
the properties of the casing construction and performance
of the unit, components and sections. These are the
following standards:
• EN1886 “Air handling units - Mechanical performance”
• EN13053 “Air handling units - Ratings and performance
for units, components and sections”
The HHFlex series is Eurovent certified for its classifications
and performance in accordance with the European
standards EN1886 and EN13053. For maximum hygiene
it is possible to produce the HHFlex completely in
accordance with all standards that are applicable to a
hygienic solution.
Certification of this hygiene application is carried out
by an independent institute. This hygiene certification
representsaqualifiedhygienestandard,whereby
testing is related to all relevant European standards
and guidelines. These guidelines define the specific
requirementsforahygienicversionofanairhandling
unit to the smallest detail.
The purpose of Eurovent certification is to reinforce
customers’ confidence. All mechanical features and
performance are measured and checked regularly
on the basis of extremely specific prescriptions,
procedures and test regulations. Deviations from
certain values are not tolerated.
This strict execution and inspection by the Eurovent
Certification Institute guarantees the performance of
a design and the reliability of the power consumption.
These designs have Energy Labelling.
The performance of HHFlex is certied by Eurovent with the
following classication in accordance with EN1886:
• Mechanical strength - D2
• Air leakage class - L1
• Filter bypass class - F9
• Thermal transmittance class - T2
•Thermalbridgingfactor-TB2
