AIR HANDLING UNITS
Air treatment
39MQ
Options/accessories
Features
• Outdoor installation (bitumen or
steel profile roof)
• Reversed extract/supply air duct
connections
• Left-hand water connections &
service side
• Outdoor air pre-heater to
prevent air-to-air heat exchanger
freezing at very low outside air
temperatures
• Rotary heat exchanger
temperature, enthalpy or
sorption types, supplied in
divided version sizes 60 to 240.
• Croos flow heat exchanger
aluminium or corrosion resistant
(coated plates)
• Air heater (hot-water or
electrical heater)
• Air cooler (chilled-water coil)
• Cool/heat change-over coil for
heat pump applications
• Direct-expansion R-410A
refrigerant coil
• Inspection chamber between
heating and cooling coils
• Inspection windows
• Extract, exhaust, outside, supply
air isolating dampers
• Recirculation / mixing damper
• Sound attenuators
• Coated coils
• Air distributor after centrifugal
fan
• 14 sizes with air flows from 0.4 to 24 m3/s (1500 to 86000 m3/h).
• The modular construction is highly flexible to combine the most optimized functions
and to offer the best running- and investment costs e.g. the type of heat exchangers
and fans with the highest efficiencies, combined with filters and coils with low
pressure drop.
• Eurovent-certified performances.
• Frame & panels made of alu-zinc AZ 185, class C4 corrosion protection (same as
aluminium)
• Casing performance (EN1886): air leakage L3, thermal transmittance T2, thermal
bridging TB4 with insulating mineral wool 50mm thickness & 50Kg/m3 density
• High-efficiency units with counter-flow plate (sizes 10 to 50) or rotary heat
exchangers (all sizes) with a thermal efficiency up to 87%.
• Standard-efficiency units with cross-flow plate heat exchangers (all sizes) with a
thermal efficiency up to 65%.
• Standard-efficiency units with run-around coil heat exchangers (all sizes) with a
thermal efficiency up to 55%.
• Large choice of Dampers (EN1751 sealing class 3), shutoff dampers & Mixing
dampers (two of three dampers for recirculation)
• Centrifugal Fans (all sizes) are a double inlet, belt-driven centrifugal fan, available as
backward-curved blades with an efficiency of up to 82% or forward curved blades
with an efficiency of up to 73%.
• Plug Fans with variable frequency drive, efficiencies of up to 75% and features very
low sound levels in the lower frequencies.
• Plug Fans are available as single-speed AC induction motor (all sizes) or EC fan with
the build in speed control (1 plug fan for size 10 to 40, 2 plug fan from size 50 to
240) with permanent magnet rotor (efficiency eqivalent or better than IE4).
• Compact filter G4 or bag filters G3 to F9 efficiency.
