5.7 Coolers
It is important for correct operation of the compressor that the LP and HP coolers are kept clean of coke deposits and other deposits from the cooling water. Inadequate cooling will result in a higher temperature of the compressed air, which will cause the progressive formation of coke.
The pipes are attached to the plates at each end of the coolers by rolling.
The seals in the ends of the coolers are of O-ring type of special quality, and only original O-rings shall be used.
To remove the pipes, first loosen the cooler covers at both ends. The entire pipe assembly can now be removed with the aid of two control rods which are pushed through the pipes. Reassembly takes place in the reverse order.
When the pipe assembly is removed, care must be taken to ensure that the locating surfaces of the O-rings are not scratched. Any such scratches which may occur can be removed with fine emery powder.
All seals and O-rings must be renewed after the cooler cover has been removed from the compressor.
If the cooler pipes show any signs of corrosion or wear, they should be replaced.
