Energy recovery

5.1.1 Energy recovery unit
Description
A large part of the energy required for any compression process is transformed into heat. For GA oil-
injected screw compressors, the major part of the compression heat is dissipated through the oil system.
The Atlas Copco energy recovery (ER) systems are designed to recover most of the above-mentioned heat
by transforming it into warm or hot water without any adverse influence on the compressor performance.
The water can be used for diverse applications.
Components
The energy recovery system is completely integrated and mainly comprises:
• Stainless steel oil/water heat exchanger
• Thermostatic by-pass valve for energy recovery heat exchanger (BV2)
• Two temperature sensors for water inlet and outlet control (3 and 4)
• The necessary bolts, flexibles, etc.
• Pressure relieve valve with pressure setting of 10 bar
• Oil drain valve.
