- ErP 2018 NRVU compliant;
- High-efficiency heat recovery units with Eurovent certification;
- Multi-speed fans or EC brushless fans;
- High-efficiency F7 and M5 filters;
- Double sandwich panel with high insulating capacity;
- Full Control kit.
Features:
- Heat recovery unit: very high-performance static type, with cross-flow aluminum fins and comparable stroke. Side-extracting exchange package (except size 40 with bottom-extracting);
- Fans: centrifugal air extraction, renewal, and exhaust fans with double suction and a directly coupled electric motor; optional high-efficiency electric motors with EC brushless technology. Fan housing mounted on vibration-damping mounts to prevent vibration transfer to the structure. EC fans can be factory-configured for constant flow operation (required at time of order).
- Construction: Extruded aluminum frame with nylon joints. Prefabricated sandwich panels: 23 mm thick, internally galvanized sheet metal, pre-painted on the outside, with highly effective thermal and acoustic insulation made of injection-molded polyurethane with a density of 45 kg/m³, providing excellent thermal and acoustic insulation.
- Filtering section: The filter sections consist of compact filters with low-pressure polypropylene cells, with side outlets, efficiency class F7 in the fresh air stream and M5 in the discharge stream.
- Factory-installed differential pressure switches for filter clogging alarms.
- Galvanized steel condensate collection tray with bottom drain;
- Free-cooling or integrated defrost bypass system. A motorized damper on the heat recovery unit enables a bypass system for free-cooling or defrost control based on thermo-hygrometric requirements.
Available options:
- UTNR-A/O PLATINUM - Heat recovery unit with a cross-flow heat exchanger, horizontal installation, and standard multi-speed fans;
- UTNRE-A/O PLATINUM - Heat recovery unit with a cross-flow heat exchanger, horizontal installation, and brushless EC fans, capable of limiting ventilation power consumption while maintaining the same performance characteristics.
