This product is part of the Sentinel Totus D-ERV range
Range Overview:
Manufactured with an aluminium frame construction with double skinned panels fitted with 60kg/m3 thermal acoustic insulation. All external panels are plastisol coated making the unit suitable for internal or external applications (IPX4). An optional inlet cowl is available for roof mounting applications if required.
The casing includes an inclined inlet and bellmouth 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 Sentinel Totus D-ERV, Demand Energy Recovery casings incorporate side access panels for maintenance.
Impellers
All Sentinel Totus 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.
Filters
All Sentinel Totus D-ERV units are complete with G4 replaceable synthetic filters, somplete with filter change warning.
Electrical
Every Sentinel Totus D-ERV unit is fitted with integrated controls and a purpose designed common user interface controller incorporating a 16-character backlit alpha numerical x 2 line display with 4 button membrane keypad for fan status and commissioning set up. This can be removed and remotely fixed if required. The unit also incorporates a isolator that is suitable for fitting a locking device to prevent accidental operation.
Motors are single phase 230V +/- 10% / 50/60Hz / 1ph. 24V DC power is provided from the unit for powering the matched range of Sentinel Demand Ventilation switches and sensors.
Totus also includes volt free contacts for BMS interfacing :
On/off control
Status Indication
