RECOMMENDED OIL

The following lubricants are recommend for use with MYCOM W series reciprocating compressors on refrigeration duty.
The customer should be advised that various mineral oils are refined from different base stocks and may contain
additives which are not compatible with a similar oil from another supplier, and that synthetic lubricants from different
suppliers may have different chemical constituents. Therefore, it is recommended that lubricants from different suppliers,
or of different types not be mixed, and that if the type or supplier of a lubricant is changed, the complete system charge
of lubricant should be replaced.
It should also be noted that the following listing of lubricants is not complete, and that inclusion or exclusion of a
specific product does not imply acceptance or rejection of that product. For specific lubricants not listed, contact MYCOM.
In the last two years Mycom Canada has conducted number of researches on available oil for Mycom W series
compressors. Canada has very special oil market where Hydro treated paraffinic oil is as popular as mineral/synthetic
oils. MYCOM W series compressor standard O-ring material is Buna-N on all NH3 compressors. Users must be aware of
compatibility of O-ring materials and followings are our recommended oil for long life operation of the compressors.

Problem on use of hydro-treated paraffinic oil for NH3 application
Buna-N must not be used on mechanical seal. Buna-N material will become hardened and shrink in volume,
which then causes premature seal leakage.
Newly developed O-rings for mechanical seals
Mycom Canada has developed the O-rings with Highly Saturated Nitril (HSN) material. These O-rings seems to
work on both mineral/synthetic and hydro-treated paraffinic oils for NH3 application.
Mycom Canada now sells these O-rings as its standard replacement parts. Color is red and they are available at
both Vancouver and Toronto warehouse

Lubrication Oil Replacement

a.In addition to daily inspection of the quantity, contamination level, color, etc. of the oil, an oil

sample should be extracted every six months for analysis by the oil manufacturer.

b.If the lubrication oil becomes extremely dirty, do not hesitate to replace it. If the oil is light

coffee brown in hue (ASTM-6 or more), replace the oil immediately.

c.Check the oil trap in the bottom of the crankcase periodically for metallic residue. If any metal

particles are found, determine the source. Residue found in the trap may include dirt from the

suction piping or particles from the frictional parts of the compressor.

d.If foreign matter finds its way into the compressor, the friction parts of the system may be

subject to premature wear or damage. It is, therefore, vital that all precautions be taken to

prevent contamination and to maintain clean oil.

e.If the oil filter mounted inside the crankcase becomes dirty, carry out cleaning immediately.

f.Check the external oil filter often to identify dirt at an early stage. If dirty is found in the

external oil filter, replacement should be carried out as soon as possible because this filter is

made of fine mesh and is prone to clogging.

g.When taking an oil sample to be forwarded to the oil manufacturer for analysis, judgment

should be made referring to the following standards

1.Oil analysis items

In general, analysis of the oil should be carried out to evaluate the characteristics

indicated below. Normally, a 200ml (200cc) sample in a clear plastic or glass bottle is

sufficient for analysis.
