Please contact us for price of this unit
Vent Axia Totus D-ERV Mini is a top-quality MVHR unit for commercial applications
Following on from the successful award wining Sentinel demand ventilation system, Vent Axia has taken the next step by incorporating the Sentinel demand control philosophy with state of the art high efficiency heat recovery to create the Vent Axia Totus Demand Energy Recovery Ventilation System (D-ERV). The Totus D-ERV mini uses the same ‘sentinel’ high efficiency ED/DC backward curved motors along with a highly efficient counterflow heat recovery cell which achieves up to 90% energy recovery, tested and rated to EN308.

- Technical Specification
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 (fire retardent to BS476 Part 7 Class 1 & Part 6 Class O).
Aluzinc panels allow for all units to be mounted either internally or externally as standard (IPX4). An optional inlet cowl is available for roof mounting applications if required. Maxi units are manufactured with an aluminium frame construction with double skinned Aluzinc panels fitted with 60kg/m3 thermal acoustic insulation. 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 Totus2 D-ERV, Demand Energy Recovery casings incorporate top and bottom access panels for maintenance (note Maxi unit is side access). Access panels are sized to enable single man maintenance. Impellers 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. Filters 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. Electrical Every Sentinel Totus2 D-ERV unit is fitted with integrated controls and a purpose designed common user interface controller incorporating a 16-character backlit alpha numerical 2 line display with 4 button membrane keypad for fan status and commissioning set up.
As standard this is mounted behind a removable perspex viewing pane allowing commissioning without accessing the wiring compartment.
The user interface 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.
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.
