SECTION 6
HEAT EXCHANGERS (OIL, AIR)
Compressor, air/oil reservoir, separator chamber and all piping and tubing may
be at high temperature during and after operation.
Do not attempt inspection or cleaning of air-cooled heat exchangers until
cooling fan has stopped rotating. Disconnect, lockout and tagout package from
power supply.
Automatic restarting or electrical shock can cause injury or death. Disconnect,
lockout and tagout package from the power supply.
OIL/AIR HEAT EXCHANGERS –
The heat of compression absorbed by the oil injected into the compressors (for
cooling and lubrication) is ultimately rejected in a convenient medium such as air (for air-cooled cores) or water
(for water-cooled cores). Proper operation of these heat exchangers is essential for the following processes:
•
The compressors require a stable, cool (167
°
F typical at 80
°
F ambient air) supply of injection oil in order to
operate at optimal efficiency. Under these conditions, the oil core allows 5.8 gpm oil flow with less than 10
psid pressure loss.
•
The lubricating and cooling oil must be kept at a normal operating temperature below 225
°
F in order to
preserve its longevity.
