Black water based paint resists corrosion for 240 hours (test in humid atmosphere - ambient 43
°C and relative humidity 100% - according to standard ASTM D 2247).
The compressors are supplied with the tube ends and the electrical connections on the unpainted
hermetic terminal.
3.6 COMPRESSOR PRESSURISATION
The compressor is pressurized to a pressure of about 0.2 bar with dry air (dew point lower than
-40 °C); the tubes are sealed with rubber plugs to maintain this pressure.
The compressors for use with hydrocarbons are supplied without pressurization.
3.7 OIL CHARGE
Table 11 shows the lubricant charged in the various series of compressors. The quantity is indicated
in the General Catalog and Technical Bulletin. Only in an exceptional case, in accordance
with the Sales Department, can the compressors be shipped without oil.
In the interest of warranty, occasionally additives or substitution of the lubricant, can be made
by the customer under the approval of Embraco Europe.
A colored “O” stamped on the compressor cover indicates the presence and type of oil (for color
and oil type see Table 11).
The maximum humidity content in the oil is 40 ppm.
