Cooler block of water-cooled GA 90 up to GA 255, GA 315 60 Hz and GA 132 VSD up to GA 315 VSD compressors
Keep the cooler block clean to maintain the cooling efficiency.
On air-cooled compressors proceed as follows:
Step Action
1 Unscrew bolts (1) and rotate the fan away from the cooler block.
2 Remove any dirt form the coolers with a fibre brush, brush in the direction of the fins. Also
remove any dirt from the fans.
3 Clean the coolers with an air jet in the reverse direction to normal flow. Use low pressure
air; if necessary, the pressure may be increased up to 6 bar (e) (87 psig)
4 If it is necessary to clean the coolers with a cleaning agent, consult Atlas Copco.
5 Reposition and fix the fan. Make sure that the fan rotates freely.
On water-cooled compressors, consult the Atlas Copco Customer Centre if it is necessary to clean the coolers.
