Sentinel Apex HR21 – Vent Axia

Sentinel Apex HR21 – Vent Axia

Passivhaus MVHR is a critical part of a Passivhaus project and its success in driving down energy usage. The performance of the MVHR system is considered an integral element of the primary Passivhaus heating demand calculation. Vent-Axia’s range of commercial MVHRs can support you with your next Passivhaus project with our most advanced MVHR systems available with wired or wireless sensors and controls. Our Passivhaus certified MVHRs provide up to 80% Thermal Efficiency, while providing an industry leading performance number of = 11.5.

Vent-Axias commercial MVHR offers free cooling through an Intelligent Summer Bypass during the warmer months, contains F7/M5 filters as standard, along with option of the MVHR to provide Demand Controlled Ventilation, Constant Pressure or Constant Volume meaning you will have full control over your indoor environment. The MVHRs include internal frost protection pre-heaters, meaning you will achieve the best thermal comfort possible at all times.

Performance simply delivered with more as standard
Vent-Axia’s Sentinel Apex range of commercial heat recovery units with up to 93% EN308 heat recovery efficiency, low sound levels and low specific fan powers the range provides high levels of performance efficiently. A new advanced control system that provides on board control, in room control and App based control full functionality commissioning and monitoring is simply provided. This control can be coupled with Vent-Axia’s new range of sensors with wired or wireless communication providing close control of, and monitoring of your indoor air quality. Sensors include CO₂, humidity and temperature and provide both proportional and switch control.

The Sentinel Apex unit is manufactured with a double skinned pentapost construction incorporating aluzinc frames and panels. The panels are acoustically and thermally treated with 90kg/m³ high efficiency acoustic and thermally insulating foam (fire retardant to BS476 Part 7 Class 1 & Part 6 Class O). The construction of the unit, IPX4, allows for internal and external mounting as standard, however, the roof assembly should be included for full external locations.

The housing is designed to be as compact as possible for concealed false ceiling applications with top and bottom access panels for maintenance. Access panels are sized to enable single person maintenance.

The fans utilised in the Sentinel Apex are the latest EC/DC external rotor motors specifically chosen for their low power consumption and low noise 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 a soft start function.

The Sentinel Apex is complete as standard with ISO ePM10 50% (M5) extract filter and ISO ePM1 50% (F7) supply, complete with a filter change warning. Filters have been selected to fully comply with the requirements of ISO16890 whilst having low pressure loss characteristics.

An integral electric frost heater is included to provide frost protection of the cell and filters down to -10°C.

The unit is complete with an integral summer bypass facility which has been designed to provide full bypass without impact to the airflow or power consumption of the unit whilst in bypass mode.

Airflow and power consumption tested in accordance with BS EN 5801. Sound data derived from independent testing at Sound Research Laboratories in accordance with EN ISO 3741:2010. Published dB(A) figures are free field sound pressure levels at 3m with spherical propagation at a 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.

An integral condensate tray is fitted along with an internal quiet running high quality pump allowing for removal of the condensate via a 10mm condensate pipe.

To facilitate normal access and maintenance to the unit there are both side and bottom access panels as standard. Should it be required, all panels are removable allowing access and removal of the heat recovery cell and all other components. A lockable isolator is fitted to the control panel preventing accidental operation whilst any maintenance is being carried out.

The electrical supply for the unit is 230V +/- 10% / 50/60Hz / 1ph. A 24V DC power is available from the unit for powering any of the matched sensors and switches.

The Sentinel Apex unit is fitted with an integrated control system as standard with a purpose designed user interface controller incorporating an alphanumerical 2 line display with 4 button keypad for fan status and a basic commissioning setup mounted within the control panel. A remote HMI is also included for that can be mounted within the room that is being ventilated. This allows for local monitoring of the unit along with the commissioning set-up.

App based control is also available via the Vent-Axia Connect App. This provides detailed commissioning and monitoring information and the ability to control the unit remotely.

A full range of sensors is available including humidity, temperature and CO₂ monitoring. These sensors are available for both wired and wireless communication with the wireless sensors being either local mains or battery powered.
