Features
• Three versions in nine sizes with air flows from 0.2 to 8.4 m3/s
(700 to 30000 m3/h).
• 39SQ units are designed to supply fresh air to any type of building. The efficient
air-to-air heat exchanger recycles the heat from the exhaust air, pre-heats
cold outdoor air in winter and pre-cools hot outdoor air in summer, resulting
in impressive energy savings.
• Eurovent-certified performances.
• High-efficiency units with counter-flow plate (C models) or rotary heat
exchangers (R models) with a thermal efficiency up to 85%.
• Casing performance (EN1886): air leakage L1, thermal transmittance T3,
thermal bridging TB3.
• Standard-efficiency units with cross-flow plate heat exchangers (P models)
with a thermal efficiency up to 54%.
• Plug & play installation thanks to factory-mounted control system.
• Delivered in one piece with integrated heating and cooling coils (only the
39SQR 1212 is delivered in two pieces).
• Field-separable casing in two pieces to facilitate installation in existing buildings.
• Plug fans with variable frequency drive.
• F7 efficiency filters.
• Main control system functions:
- Air flow control: constant volume, constant pressure, variable volume
(demand ventilation with CO2 sensor)
- Temperature control: extract or supply air temperature, room temperature
sensor
- Summer night free-cooling control
- Alarm indication: temperature too low, coil frosting, clogged filters, etc.
- Easy local or remote access by integrated web server (no specific software
required)
- RS485 communication port
