This product range is now obsolete and no longer available from Vent-Axia. The information here is provided for reference only.

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 Additional Interlock are avaialble : Remote Heater Interlock Heating System Interlock Air Conditioning on/off Performance/Sound Extensively tested to BS848 parts 1 & 2. Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at reference level of 2 x 10-5 Pa. The inlet/outlet sound power level spectra figures are dB with a reference of 10–12 watts.

AirTrack Duct Air Heater - with Controls
The Vent-Axia range of sheathed element air duct heaters with built in control system provide a safe method of air heating which is economical to install and operate. Circular Duct Air Heaters comprising of electric resistance elements, mounted in a pregalvanised steel casing. Every heater is fitted with a high temperature safety cut out operating at 120°C complete with push button manual reset. Available in 100, 125, 150, 200, 250, 315 and 400mm diameter sizes. The air velocity across the heater elements must be greater than 2m/s and installed a minimum distance of one metre from the exhaust outlet of the fan unit. All fans supplying heaters above 6 kW should be fitted with an off-delay timer to dissipate any residual heat when the system is shut down. Duct heaters must be used in conjunction with a fan heater controller and a temperature thermostat (room or duct) and an air pressure/flow switch.
