MINI and MIDI Models are manufactured with a frameless construction from single skinned Aluzinc panels, internally lined with 90kg/m3 high efficiency acoustic and thermally insulating foam.
MAXI units are manufactured with an aluminum frame construction with double skinned Aluzinc panels fitted with 60kg/m3 thermal acoustic insulation
The casing includes an inclined inlet and bell mouth entry which directs the incoming air to the impeller with minimal turbulence. The result is better air management through the unit, less noise, higher efficiency and an increased performance.
The housing is designed to be as compact as possible for concealed false ceiling applications and incorporate top and bottom access panels for maintenance (note Maxi unit is side access). Access panels are sized to enable single man maintenance.
All Sentinel Totus2 D-ERV units feature low energy, Class 1, EC/DC external rotor motor and backward curved impeller assemblies specifically chosen for performance and nonoverloading characteristics.
The assembly is dynamically balanced to DIN ISO 1940 Grade 6.3. Ball bearings are greased for life. Insulation is Class ‘B’ (from -25°C to +60°C).
All models incorporate internal electronic overload protection and soft start function.
All Sentinel Totus2 D-ERV units are complete as standard with G4 replaceable synthetic filters, complete with filter change warning. High grade F6 filters are available as an option.
Motors are single phase 230V +/- 10% / 50/60Hz / 1ph.
On demand 24V DC power is provided from the unit for powering the matched range of Sentinel Demand Ventilation switches and sensors.
