HVR range – key features:

· Brushless digital fan; high performance brushless digital fan delivers industry leading ventilation performance to power usage. Large flow volume reduces fan speed to a minimum thus reducing noise output;

· Motorised louvre grille; a profiled louvred grille (to reduce noise) directs ventilation air within the room the system is serving. Incorporating metal geared actuators, the louvred grille allows air flow to be automatically varied dependant on season or on user control;

· Low resistance heat exchanger; hydrophilic coated aluminium cross flow heat exchanger minimises resistance to airflows, lowering running costs and reducing maintenance, 43-51% sensible efficiency;

· Multiple segregated internal airways allow selectable ventilation air pressure strategies from natural ventilation, hybrid ventilation and mechanical heat recovery ventilation (Patent application 48086GB);

· Sensors; in-built temperature sensors continually monitor airflow temperatures and indoor air quality

· Acoustic profiling; imbedded Helmholtz resonance cavities within the casing reduce fan noise and minimise ventilation air movement noise (Patent application 48039GB);

· Acoustic engineered; the densities and thicknesses of the acoustic EPP material vary along the body of the system maximising acoustic properties and air flow through the system;

· EPP structure; Flame retardant Expanded Polypropylene (EPP) is steam fused to form the complex airflow paths within the system. EPP provides acoustic and insulative properties and is fully recyclable;

· Aluminium casing; aluminium sheets are profiled and then coated in industrial layers of white RAL 9016 powder coating. Speed fixings;

· Mixed air adjustment; uPVC volume control blades with integrated seals adjust air flows between natural, hybrid and heat exchange;

· Inclined profile; the mounting of the scroll fan maximises exit velocities causing the ventilation air to align along the acoustic surfaces;

· Recirculation & exhaust grille; the Injection Moulded lower grille using a honeycombed structure to maximise airflow through the grille proving the least resistance and minimising air flow noise;

· Exhaust air; an upper horizontal profile allows air to be exhausted from the room. This air can either be passed through the heat exchanger or from higher level exhaust grilles;

· Intake air; a lower horizontal section brings fresh air into the system;

· Coils; designed for operation traditional LPHW, CW or heat pumps up to 3.5 kW output;

· Nominal dimensions; 1250 x 950 x 298mm (1450 x 950 x 298mm with coiling coil);
