TO INSTALL
SenerTec have installed over
32,000 Dachs units throughout
Europe and have over 20
years’ experience in CHP
technologies. Baxi-SenerTec
UK are considered the leading
authority for mini-CHP in
the UK market.
Feature
Benefit
Installed close to where the electricity and heat
are to be used
Electricity isn’t lost during transportation
Easy to install
Very little down time means it is more convenient
for the end user
Design life of 80,000 hours of continuous running
Cost effective and reliable for its lifetime
Internal combustion engine driving a maintenance free
3-phase asynchronous electrical generator
Proven, long-lasting, reliable technology
750 litre buffer vessel for connecting 1-3 Dachs units
For improved running and increased efficiency
DachsPortal for remote monitoring of the system
So you can plan maintenance and ensure optimum
performance at all times
