CHP 500

HGM240 High efficiency gas engine

500kWe Combined Heat and Power System
Dresser-Rand® pro­ ides a comv
plete range of fully packaged
and tested combined heat and
power (CHP) systems to commercial, industrial and municipal energy users world­ ide.
w
CHP (or cogeneration) systems
reduce on-site energy costs and
carbon emis­ ions through the
s
highly effi­ ient delivery of power
c
and heating. Our packaged
system may also be coupled
with absorption chillers in order
to deliver process or comfort
cooling in addition to heat and
power output. Combined cooling, heat and power systems
(CCHP) are also refered to as
trigeneration.

CHP systems offer an environmentally-friendly option for the provision of
electricity and heat by recovering thermal energy that would typically be wasted
in conventional power plants. With standard modular CHP systems ranging from
180kWe to 1300kWe, a Dresser-Rand packaged CHP solution increases energy
productivity, efficiency and reliability, while substantially lowering clients’ carbon
footprint and energy costs.
