VA-TOTUS-MAXISentinel Totus 2 MAXI D-ERV MVHR Unit (TOTUS2MAXI) - Sensor Control

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.

Vent-Axia Sentinel Totus 2 Maxi D-ERV Commercial MVHR Unit.

Ideal in applications where rooms are used intermittently. The Sentinel Totus 2 maxi can monitor occupancy and respond to the ventilation demands of a room adjusting atmosphere accordingly. A range of sensors of controls are available that can monitor carbon dioxide levels, temperature humidity or air quality.

Features of the Totus 2 Maxi by Vent-Axia:-

  • Designed to operate at airflows of up to 2000m³/hr at 150 Pa.
  • Fitted with high efficiency low energy EC/DC motor technology.
  • ERP 2015 compliant fans.
  • Recovers up to 90% of extracted energy.
  • The Sentinel Totus² range is fully compliant with both Part F and L UK building regulation requirements.
  • 90% heat exchange efficiency independently tested to EN 308.
  • Inbuilt automatic frost protection.
  • Low standby power 0.6watts (PIR activation).
  • Monitors occupancy and responds to the ventilation demands of a room.
  • The units contain heaters, which automatically prevent the heat recovery unit from freezing. These can also be used to top up the air temperature to the room.

Typical applications for the Sentinel Totus 2 Maxi:-

  • A network of hotel rooms/bathrooms flats or apartments that are used for limited periods such as mornings or evenings.
  • Schools classrooms that are occupied by a variable number of people. Sensors can keep CO2 levels within prescribed limits.
  • Office environments which have a variable number of staff and visitors that when occupied must meet prescribed airflow rates.
