Sentinel demand ventilation is a closed loop controlled ventilation system. Employing a range of sensors to manage the system, demand is sensed by PIR, temperature, humidity, air quality or carbon dioxide sensors.
Depending on the levels in the rooms, Sentinels fan speed is ramped up or down to control the parameters within the required limits. If the room is unoccupied, the system switches off, saving energy and cost to the business. Available in single or twin fan configurations, twin allowing for load sharing or standby for extra reliability.

Sentinel utilises the latest EC/DC motor technology, which provides energy saving benefits even over DC motors as switching is undertaken electronically with no physical contacts reducing wear, heat losses and improving reliability.
This technology is also infinitely speed controllable and offers increased energy savings across the complete speed control range when compared with conventional inverter drive solutions.
The result is higher efficiency, reduced noise, accurate controllability, better speed control drawing less power and as a result better overall system performance.
The EC/DC motor offers higher efficiencies when compared to AC
motors, and also consumes less power under speed control, giving both the highest motor efficiency and lowest power
consumption across the speed control range.
