Heat Recovery Unit

Used in homes and small volume areas to provide fresh air and to exhaust polluted air.

• Up to 95% efficiency with high efficiency counterflow plate heat exchanger

• Low energy consumption and low noise level with EC Plug Fan

• High efficiency - complies with ERP and Eco-design / ERP 2018

• Advanced automation system

• Plug & Play

The fans in heat recovery units are equipped with innovative Electronically Commutated EC motor technology. EC motors have higher efficiency and simple speed control than AC motors and connect the AC mains. Fan blades have high aerodynamic efficient backward curved design. Using the EC motors reduce the energy consumption and increase the energy efficiency of the unit. With EC Fans it is also possible to reduce maintenance costs as the fans are direct drive; free of belt and pulley.

High corrosion resistive 200 gr/m² galvanize coated steel is used for the casing. The case of unit is painted by electrostatic powdered paint. Non-flammable EPS modules are used for directing the air flow homogeneously. Density of EPS is 40 kg/m³.

To increase indoor air quality and to protect the equipments used in unit, G class filters (according to EN 779 standard) are used for both exhaust and supply air streams. F class filters can be also used optionally in the unit. F class filters reduce the available static pressure of the unit for the nominal air flow rate. 

Event 300 units have by-pass ventilation as standard. During by-pass ventilation, no heat transfer occurs between exhaust and fresh air stream. In transition periods and at nights in summer, by-pass module helps to cool down (free-cooling) and heat up (free-heating) the building without any energy expense.
