KAESER BSD 50 User Manual

S-SERIES:
■ S-Series SIGMA compressor cooling oils are synthetic lubricants.
■ S-Series SIGMA compressor cooling oils are formulated from the most advanced synthetic lu‐
bricants. These ”synthetic” lubricants begin as high quality petroleum feed stock. They are then
refined, processed and purified into fluids with very consistent molecular structure. These oils are
carefully blended to produce extremely consistant lubricants with superior properties. SIGMA
synthetic lubricants feature all the advantages of both PAO and diester fluids.
■ S–460 lubricant is recommended for compressors operating in ambient temperatures between
40 °F and 105 °F.
Specialty KAESER LUBRICANTS:
■ S–680 lubricant may be used when ambient temperatures are always between 70 °F and 105 °F.
■ FG–460 synthetic hydrocarbon based food grade lubricant is designed for use in rotary screw
compressors in the application where incidental food contact may occur with the discharge air.
This lubricant meets the requirements of the FDA Regulation 21 CFR §178.3570 and is USDA H–
1 approved and NSF certified. FG–460 is approved for canning, food packing, meat and poultry
processing and other applications where incidental food contact may occur.
2.10 Cooling oil charge
The required cooling oil charge depends on the optional heat recovery system. For machines with
options W1, W2, or W3, the volume required additionally for the heat recovery must be added to the
charge.
