On-demand D-ERV system

To help cut carbon emissions and reduce energy costs, Vent-Axia has introduced the Sentinel Totus DERV (Demand Energy Recovery Ventilation) system.

Sentinel Totus integrates the ondemand control with EC/DC motor technology and a counterflow heat recovery cell to achieve up to 90% energy recovery. It is also reported to be the UK's first D-ERV system to be independently rated and tested to EN308.

Sentinel Totus responds to the precise ventilation requirements of a room, providing the right level of supply and extract airflow at any one time, making it suitable for areas with changing occupancy patterns.

The system also recovers energy (heat and cool) from the extracted air, transferring it into the fresh air supply via an integral high efficiency counterflow heat exchanger.
