Compact CHP units 40 400 kWcompact efficient reliable
With their highly efficient, clean and economic
productionofelectricity and heat, CHP units (Combined Heat
andPower, also: cogeneration) make a substantial contribution
to a sustainable energy supply.
Compared to the conventional supply, natural gas
poweredSOKRATHERM CHP units reduce the primary energyconsumption by
ca. 40% and the CO2 emissions by ca. 60%.That is why such plants
based on the highly efficient prin-ciple of cogeneration are
supported by laws or subsidiesin many countries.
SOKRATHERM, one of the leading German CHP unitmanufacturers in
its power range, offers cogenerationunits fuelled by natural gas,
sewage gas or biogas in fourpower classes.

COGENERATION = EFFICIENT ENERGY
CHP units allow the efficient generation of heat and poweron
site and without transmission losses. In contrast to largepower
plants, they can be turned on an off and regulatedto partial load
within seconds. This possibility to quicklysupply electricity
grants them an increasing importance inthe energy mix, also to
balance the production fluctuationsof renewable energies.
The core piece of the CHP unit is a combustion enginepowering an
electricity generator. The generated power isconsumed by the
on-site load or can be fed into the mains.The heat generated in the
combustion process is extractedby a series of heat exchangers and
can be used for heating,hot water generation, process heat or even
cooling.
With this double utilization of energy, our CHP units reach
efficiency rates of ca. 90% and even higher if the
optionalexhaust condensation heat exchanger is chosen.

FLEXIBLE APPLICATION
Our CHP units may also be configured to take over the
elec-tricity supply of defined consumers (e.g. pumps, sprin-klers,
production lines, computers) in case of mains failure.
It is also possible to fit them as hot coolers to operateon a
higher temperature level (95/80 C) than standard(90/70 C) to supply
e.g. absorption chillers.
The modular design allows a combination of our compactCHP units
in size and numbers to exactly match thebuilding and its users
because hospitals have a differentpower demand than office
buildings, swimming poolsother heating needs than industrial
sites.

With their compact design, our CHP units convert theengine power
and combustion heat with the least possiblelosses into electricity
and useable thermal heat. This way,the space requirement on site is
minimized as well as theeffort for the insertion.
RELIABLE OPERATION
The ISO 9001 certified production tailored to the custom-ers
needs is followed by an extensive test run and a sub-sequent first
service before shipping. We manufacture ourcompact CHP units with
switchgear cabinet integratedin the sound absorbing CHP case ready
to operate and cancommission them very quickly. Their triple
elastic bearingprevents vibrations from spreading to the building.
There-fore, a separate founding is rarely required.
Only long-term proven components from well-known pro-ducers are
used our units. This way we achieve a minimumfault potential at
maximum quality, which is regularly con-firmed by our customer
satisfaction surveys.
SERVICE
An integral part of our offer are well-engineered mainte-nance
concepts which are continuously adapted to the tech-nical progress.
For every CHP project, we offer individualservice packages from the
simple regular service withcustomer participation to the
all-inclusive carefree packageincluding operation optimization and
general overhaul.A network of service points makes sure that our
customersalways have competent service personnel nearby.

CHP UNIT SIZING
To achieve the best economy, the CHP unit covers the heatand
power baseload while the peak loads are covered by boil-er and
power mains. The CHP size is usually determined bythe locations
maximum heat demand (Qmax). Dependingon climate zone and the cost
of power and gas, a profitableoperation can be reached when the
heat output of the CHPunit is 10 30% ofQmax. In special cases, e.g.
for peak oremergency power supply, the CHP unit is sized by the
elec-trical power demand.
MULTI UNIT PLANTS
For better adaption to the heat demand and/or to achievea backup
supply, the required power can be split up intoseveral CHP
units.

SOKRATHERM CHP unit controlSafe and smooth operation
Superordinate controls are also part of our product range:For
the control of rather simple plants with a CHP unit,
a boiler and a buffer, the MiniManager control is
alreadyincluded. Plants with a CHP unit and e. g. several boilersor
an extended buffer management can be controlled withthe MiniManager
PRO system adapted to the specificCHP project.
Large CHP plants with several CHP units, boilers and
e.g.emergency power supply can be controlled with the Maxi-Manager.
This secures a centrally supervised, efficient andruntime optimized
operation of the single CHP units.
