Systems designed to recover energy
February 1st 2008 More than ever, businesses and
the general public want the
same thing – energy that is cost
efficient, reliable and
environmentally safe. Through
its businesses, diversified
industrial company Ingersoll
Rand develops energy
management and generation
products and services that make
it possible to achieve these goals.
One of these products is its
Energy Recovery System. Air
Cooled rotary screw compressors
are a source for recovery of heat.
The heat of compression is
transferred into the compressor
coolant during the compression
cycle. In a standard air-cooled
machine, this heat is transferred
to the cooling air and discharged
from the package. By
exchanging the heat of
compression in a water/coolant
heat exchanger, the heat of
compression can be re-used for
other processes.
The Energy Recovery System is
modulated with a simple
temperature bypass valve. The
heated water can be used for
industrial applications such as
pre-feed to boilers or industrial
cleaning processes, or domestic
applications like central heating,
showers, and sinks.
Benefits claimed for Ingersoll-
Rand's ERS include superior heat
transfer, closer approach
temperature, no additional
energy losses from the
compressor, and maximum
energy recovery. The simple
design is said to ensure minimal
wear and tear and minimal
maintenance costs. More articles from Ingersoll Rand European Sales Ltd: |
