Turn around your business with CHP... WHAT ARE THE BENEFITS?
Careful design and ongoing management can deliver efficiency savings of up to 50% on existing energy overheads.
Reduce the reliance on supply utilities and guard against rising energy costs.
Engines have been developed to run on less carbon intensive fuels which have environmental benefits as well as reducing energy costs.
CHP is flexible with models that can be wall hung in a utility room through to multi megawatt energy centers of the type chosen for the 2012 Olympic Games.

IT’S ALL IN THE EFFICIENCY...
WHAT IS CHP? Cogeneration or CHP is a means for building owners and managers to more efficiently use available energy sources and thereby reduce the overall demand for energy.
WHICH BUILDINGS? Buildings that benefit the most shall have a reasonably constant demand for energy such as Schools with swimming pools, Hospitals, Hotels, Leisure complexes and heavy industry.
SOLVING THE PUZZLE The central task for the engineer
System Electrical Efficiency (%) From Energy Input
is to gain an understanding of the load profile and to closely match the building demands with the outputs of the CHP so that
Fuel cells
maximum savings in energy are achieved.
