1. Construction Heat recovery units TANGRA EVB HiE are produced in compact or modu-lar construction with aluminum anodized framework with two types of side panels:- Single panel with internal sound and thermal insulation (13mm)- Double wall panels (sandwich type) with 25mm sound and thermal insulation.

2. Air filters (EN779 / ISO16890)All heat recovery units TANGRA EVB are with incorporated filters for fresh and exhaust air. The standard filters are panel or mini-pleat M5÷F7 (EN779) or ePM1÷ePM2.5 (ISO16890). On request additional filters can be added after the unit in a filter box with fan, due to pressure drop and needed available free static pressure from the unit.

3. Antifreeze protection / pre-heater (option)Due to high efficiency of the heat exchanger in winter conditions the air flow can lead freezing and ice blockage of the exchanger. In order to prevent it an electric heater for anti-freeze protection of the fresh is in-corporated in the units. It turns on automatically based on the conditions and is smoothly controlled to minimize the consumption. 4. By-pass (Regulations EU 1253 and 1254)Automatic bypass damper with servomotor actuator that allows free cool-ing in summer mode (without heat recovery) or variable control when mixing section is in use.

5. Heat exchanger (Eurovent cetrified)All heat recovery units TANGRA EVB are with high efficient plate heat ex-changer and heat recovery coefficients exceeding 79% (EN308). No odors or moisture transfer between the streams. The plate heat exchangers in TANGRA EVB are certified by Eurovent Certita Certification S.A.S.

6. FansHeat recovery units TANGRA EVB are equiped with 2 different types of centrifugal fans. The fans are marked on every graph, based on the electric motors: AC or EC/EC+ . - The units with AC are with centrifugal fans with forward blade wheel - economic solution with easy variable control on the voltage. - The units with EC/EC+ are with high performance radial freewheel impeller and IE5 EC motors.

7. Electric boardTANGRA EVB are plug and play solution. Their intelligent control systems allow quick and easy commissioning. The state of art controls have BMS connection or control through internet (Modbus, BACnet, etc.). TANGRA control systems can be equipped with wall mounted remote LCD display. Sensors for constant flow or pressure, CO2, VOC or rH.

8. Thermal boxTANGRA EVB HiE can be equipped with an external module with integrated water heating coil or DX coil for connection with outdoor VRF. Removable mist eliminator is on request.

9. Multi-leaf dampers (option)Aluminum louver dampers for tightly closing of the inlets and outlets with external servomotor actuator. Tightness category 2 to EN 1751.

10. Flexible joint (option)Rectangular flexible joint for easy connection to ventilation ducts and eliminating all the vibrations between the unit and the duct system.

11. Round connector Round connectors designed for direct connection to spiral ventilation ducts.
