VEX500

VEX500 brings fresh, filtered air (up to 90% of PM1) into the building and recovers heat from exhaust air using its very high-efficiency heat exchanger. The incoming air can be heated and/or cooled using a full range of coils.

• pre-wired monobloc unit featuring self-supporting construction with dual-wall panels,
• 50 mm mineral wool insulation, density 40 kg/m3,
• high-efficiency counterflow plate heat exchanger up to 95% (AAHU-certified),
• EC motor and high-performance backward curve impeller,
• 100 % and adjustable bypass control,
• G4 filters (Coarse 60%) on exhaust and F7 (ePM1 60%) on fresh air as standard,
• optional: M5 (ePM10 50%), F9 (ePM1 90%),
• wide range of coils,
• built-in switch,
• Aldes Smart Control® system:
  • constant speed,
  • constant airflow,
  • constant pressure,
  • variable airflow according to CO2/VOC sensor (0-10 V signal),
  • pressure control: adapts pressure to airflow measured, for very high energy efficiency,
  • built-in clock: timer control.
• configuration & monitoring via:
  • remote touch-screen control,
  • built-in webserver,
  • BMS via ModbusRTU, Bacnet, TCP/IP.
• de-icing by electrical coil on exhaust air or by controlled bypass opening

• coil options:
  • electrical,
  • electrical post-heating,
  • hot water with or without 3-way valve,
  • cold water with or without 3-way valve,
  • reversible (hot/cold) water with or without 3-way valve.
• aluminium or galvanised steel + paint condensate collection tray on heat exchanger,
• monobloc roof piece fitted in factory for outdoor versions,
• access to all components on the main panel via hinged, removable doors, and to control system via a specific central hatch,
• steel access doors pre-coated in dark grey (RAL 7016),
• galvanised steel or pre-coated external finish (RAL 9006) depending on the version,
• M0 interior finishes made of Z275 galvanised steel.

• equipment rooms / flat roofs,
• indoors /outdoors,
• in-line duct connections,
• rectangular connectors (circular adapters available as accessories),
• choice of utility connections side - left or right.
