Cooling oil charge
M-SERIES
■
M-Series SIGMA compressor cooling oils are semi-synthetic lubricants.
■
M-Series SIGMA compressor cooling oils are the highest quality petroleum lubricants. M–460
is specially blended to provide reliable performance in KAESER screw compressors.
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 consistent 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-1approved and NSF certified. FG-460 is approved for canning, food packing, meat
and poultry processing and other applications where incidental food contact may occur.
Cooling oil charge
For machines with the Option W1, the volume required additionally for the heat recovery must be
added to the charge.
Fluid volume* [qt]
Topping up volume [qt]
(minimum–maximum)
* Plus the oil volume of the heat recovery system.
Cooling oil charge (Option K1)
Heat recovery
The additional volume corresponds to the oil volume of the heat exchanger and the connecting
lines:
Additional charge vol‐
ume [qt]*
* Enter the volume required by your heat recovery system.
