On-demand D-ERV system
January 1st 2010 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. More articles from Vent-Axia Limited: |
