5. Energy Recovery (ER)
5.1. Description
The energy required in any compression process is mainly transformed into heat. In oil-injected screw compressors, most of
this compression heat is dissipated through the oil system. The Energy Recovery stand alone kit is designed to recover most
of this heat by transforming it into warm/hot water without adversely affecting compressor performance. The water can be
used for various applications.
5.2. Components
The stand alone energy recovery system comprises:
•
Completely
stainless steel
oil/water heat exchanger.
•
Thermostatic bypass valve with on/off lever.
•
Temperature sensors for water inlet and outlet control.
•
Necessary bolts, pipes, hose assemblies, etc.
•
The Energy Recovery system also includes thermostats for both the bypass valve of the Energy Recovery unit and the
main bypass valve of the oil filter pipe.
•
Flexibles to connect the kit to the main compressor
•
Tap flange (except for GA 11-30 kW range)
