All SOKRATHERM CHPs can be upgraded to serve as
emergency power generators. These are mainly used in
local facilities but are also suitable for emergency power
supply on industrial sites, i.e. for sprinkler installations,
elevators and computer systems.

CHP: All-rounder
A SOKRATHERM CHP provides a customised solution –
for producing environmentally friendly electricity and
heat but also as a locally positioned standby-set.

To enable the CHP to operate parallel to the national grid
as well as a standby set, the CHP can be fitted with a
three-phase synchronous generator and an automated
control system.

The CHP can be fitted with a heat exchanger for supplying
only electricity if there is no requirement for heat supply.

This is what happens should the national grid break down:
If the CHP was operating while connected to the national grid,
the automatic control system cuts the CHP off the national grid
and the CHP immediately takes over all emergency power
supply without disruption.

If the CHP was not operating when the power cut occurs,
the CHP's automated control system cuts off everything
that requires emergency power off the system.
Then – after a maximum of 15 seconds – the CHP supplies
the first asset in the emergency power supply chain, i.e.
the sprinkler installation. Then after another 5 seconds all
other systems will be reactivated one after each other,
i.e. elevators or computer systems.
A so called "back-up battery" (USV) takes over in the short
gap between the power cut and the emergency power supply.

When the national grid is available again, everything will be
synchronised back over and the CHP will automatically
reconnect with the national grid without a disruption.
The unit will then operate in parallel mode and will be controlled
via the MiniManager or the buildings control system.
