Oil-free Reciprocating High Pressure Oxygen Gas Compressor
A reliable and uninterrupted operation of this unit (for the three options), in conjunction with the existing one is of essence. This mode of operation must be ascertained in all facets like : design, selection of equipment, accessories and controls, fabrication and construction of the unit, stand-by equipment and spares, etc.
The performance of the Oxygen Generator is shown in Table 1, below :
