WiseAir 350 & 550 HRV systems
The WiseAir 350 & 550 units are equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger. The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.
Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates. In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively.
In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air. That reduces operation load on air conditioners and saves electricity
Design
- The casing is made of double-skinned polymer-coated steel panels, internally filled with 20, 25, 30, 40 mm (depending on the unit model) mineral wool layer for heat- and sound-insulation.
- The unit is equipped with a hinged service panel to enable convenient access for maintenance or repair operations.
- The spigots are located at the top of the unit and are equipped with rubber seals for airtight connection to the air ducts.
Features
- Air handling units for efficient energy saving
supply and exhaust ventilation in flats,
houses, cottages and other premises. - Heat recovery minimizes ventilation heat
losses during cold season and reduces air
conditioner load during hot season. - Controllable air exchange for creating the
best suitable indoor microclimate. - Compatible with round ∅ 125, 160 or 200 mm
air ducts.
Fans
The units are equipped with high-efficient EC motors with an external rotor and a centrifugal impeller with backward curved blades. EC motors have the best power consumption to air capacity ratio and meet the latest demands concerning energy saving and high-efficient ventilation. EC motors are featured with high performance, low noise level and optimum control across the entire speed range. The impellers are dynamically balanced
App
The WiseAir app allows the user to remotely control the Heat Recovery Unit. The app is available on both the App store and the Play store.
