2.1 INTRODUCTION
The Sullair Integral Heat Recovery System is a
means of recovering energy which is expended
while producing compressed air. This energy can
be converted into a usable source of heat. The heat
is stored in the compressor cooling air as it passes
over the compressor motor, fluid cooler and after-
cooler. The compressor cooling air can then be
used as preheated make-up air or heating air for
plants, warehouses, etc. Heat may also be rejected
from the system when it is not required.
Any make-up air introduced into a heating or ven-
tilation system by this system must be of breath-
ing air quality as defined by applicable codes,
laws or regulations.
Because the heat recovery system is built into the
compressor package it requires a minimal amount
of installation labor. The system has been
designed so that use of auxiliary blowers is not
needed as long as good duct design is practiced
(See
Section 4.4 ).
