The units are applicable to HVAC systems where fresh air demand is high as a result of intense occupancy like cinemas, shopping malls, airports, office buildings, high-rise buildings, sport arenas, conference rooms and museums. With the help of hygroscopic rotor the unit is capable of transferring both heat and moisture between exhaust and supply air streams and increase energy savings in the HVAC system. EOVENT units deliver a compact design for ventilation and air conditioning applications with direct drive plug fans with EC technology, hygroscopic rotor, exhaust and supply air filters and electronic control. For applications like high humid areas, food warehouses where humidity transfer between air streams is not demanded Aluminum type heat exchanger installed EPO model is also available. EPOVENT units have the same energy efficient characteristic like EOVENT units, due to crossflow heat exchange the nominal efficiency of the unit is reduced. Summer cooling function is attained with by-pass ventilation module. Electronic control is installed within the unit, no additional equipments are needed on site, only mains connection enhancing Plug and Play design. Microprocessor based control system operates the unit according to design conditions by checking temperature, air flow or indoor air quality. Electronic control concept is developed for several demand options of the designer, including various communication.

3 EOVENT EOVENT and Fans EOVENT units are equipped with innovative Electronically Commutated (EC) motor technology.ec motors ensure the flexibility of connecting to AC mains with the efficiency and simple speed control of a DC motor. Fan blades has high aerodynamic efficient backward curved design. With the new energy regulations, pressure drop in the ducting system shall also be minimized due to low energy consumption demand.with EC Fans it is also possible to reduce maintenance costs as the fans are direct drive; free of V-belt wear and tear mechanism. Control EOVENT units are equipped with a microprocessor based control system, GreenBox to meet various design needs. Both electrically and electronically control hardware comes with the unit that s why the unit is Plug and Play. otor monitoring and speed control, filter monitoring, fan monitoring are standard. With the use of optional IAQ, CO 2 sensor or constant flow kit, fans regulate automatically according to user demand. The panel is BMS compatible and can handle various communication protocols like Modbus (standard protocol for EOVENT units), Bacnet and Lonworks. oom control panel is supplied where no BMS protocol is demanded. GreenBox is also capable of controlling heating/cooling capacity when EOVENT units are used with heating/cooling coils. Duct Connections EOVENT units outlets are designed in rectangular shape. Adapters can be used after the unit to convert it into circular duct system. To reduce pressure drop in both inlet and outlet, face velocity is reduced (Maximum air velocity in the duct connection Vmax<4,5 m/s). Motorized or manual dampers are optionally available for both fresh air inlet and return air inlet. and Filters EOVENT units are equipped with G class pre-filter and F class final filter in supply air side and G class pre-filter in exhaust air side. A choice of pre-filters (G2-G4) and final filters (F6-F9) are available optionally. Pre-filters are washable and secured in rigid frames made of galvanized steel. Final filters are innovative compact filters with increased filtration surface area to reduce initial pressure drop over the filter and also reduce units size. All the filters comply with EN 779 to meet the requirements of odor absorption and dust arrestment. Filter blockage is indicated in the control panel by standard installed differential pressure switches however pressure gauge is also available optionally to observe fouling. Filter sections are designed to ease filter service and changing. otary Heat ecovery The rotor consists of a) Heat Storing Matrix b) The Drive. The rotor matrix consists of Aluminum foil. A bond formed in waves is wrapped together with a straight bond on top of each other. In this way, depending on the height of the waves, flow-through channels are created of different size, the shape of which is a measure for the efficiency but also for the pressure drop. In EOVENT units the height of the waves are optimized for maximum efficiency and minimum pressure drop. The drive consists of a three-phase motor that rotates the rotor ten times in a minute in the case of full efficiency. By reducing the number of rotations, a reduction of both heat and humidity can be achieved. The speed of the rotor is controlled between -2 rev/min by the Greenbox control. The rotor has a purge section to reduce the possible leakage between supply and exhaust air streams. Also with the help of the purge sector the rotor achieves high self cleaning on account of the continuously changing directions of air flow in the purge sector. Casing The unit is constructed in sections to ease transportation, mounting and commissioning. Every section has its own basis and transport slots. For both panels and service doors internal casing is galvanized steel and external casing is powder coated. mm thickness of ockwool is used for thermal and sound insulation. Each service door has locking mechanism to ensure safe service. To prevent thermal and fluid leakage through the casing, appropriate gaskets are designed. 3 4
