FEATURES |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Reliable – Our continuous duty units utilize industrial engines,
generators, and auxiliary equipment designed to provide prime power around
the clock and across the calendar as desired |
| Thermal Heat – Our cogeneration units are
designed for maximum heat recovery, ensuring plenty of thermal energy for
applications such as domestic hot water, heating, etc. |
|
|
|
|
|
|
|
|
High
Efficiency – Our generating platform is recognized as
being an industry leader in efficiency, ensuring that the maximum amount of
fuel energy is converted into useful power |
| Absorption Chilling – Our systems are
designed to easily integrate with our full line of absorption chillers in
order to effectively deliver chilled water or brine for cooling
applications |
|
|
|
|
|
|
|
Environmentally
Friendly – We take pride in helping make the air
cleaner. Our low NOx systems exceed
the most stringent air quality standards anywhere in the world |
| Remote Control – Accessible remotely and
securely by PC, onboard microprocessor-based control systems assure high
levels of performance, availability, and protection |
|
|
|
|
|
|
|
Economical – The combination of operating efficiency and low installed cost
ensures that cogeneration is financially attractive. Our Value Share option eliminates
out-of-pocket costs |
| Parallel / Isolated – Our units can run
with or without interconnection to the utility grid. Synchronous generator-equipped units can
provide emergency power during an outage |
