Decentralized KWL blower units EventAir 2.0/2.0 SE with heat recovery (V=up to 40m³/h) and accessories

The EventAir 2.0 ventilation unit is a decentralized ventilation system for controlled room ventilation with heat recovery. Using several devices in pairs enables complete residential units/buildings to be ventilated. During operation with heat recovery, the ventilation unit works in 2 time intervals. In the first phase (exhaust air phase) the room air is discharged outside via the ventilation unit due to the fan’s exhaust air mode. In doing so, the air flows through the ceramic heat accumulator inside the ventilation unit and heats it. In the second phase (supply air phase), the ventilation reverses the direction of delivery and fresh external air is fed into the room via the ventilation unit. In doing so, the air flows through the heat accumulator, which gives off the heat that has previously been stored into the air. In this way, up to 99% of heat can be recovered. The principle of loading and unloading a heat accumulator is known as regenerative heat transfer. When operating an individual devices, depending on the operating phase, an overpressure (supply air phase) or vacuum (exhaust air phase occurs). In order to ensure a balanced ratio between supply and exhaust air volume, it is recommended to use the EventAir 2.0 units in pairs. The EventAir control 2.0 enables the joint operation of up to three pairs of devices.

• 2 operating modes: Summer mode (supply or exhaust air mode without heat recovery) Winter mode (reversing mode with heat recovery)
• Sleep timer function (device switches off at the touch of a button and goes back into operation after 2 hours’ sleep time)
• The heat exchanger can be easily cleaned, as the internal components can be fully removed
• Expandable to 10 or SE version to 18 units with expansion set (98 007 69)
• SE version without integrated humidity sensor
• Can only be operated via an additional control system
