In highly-sensitive applications, the requirements for compressed air treatment are very demanding – especially when the compressed air comes into direct contact with units and products, and when mineral oil contaminations can endanger the production process. The provision of constant “oil-free” compressed air is an important measure for food safety, quality assurance in medicine production and in production or packaging processes.
With future-oriented catalysis technology, BEKOKAT is setting new standards and reducing mineral oil residues in compressed air. The unit fully converts hydrocarbons into carbon dioxide and water through total oxidation. The procedure provides constantly oil-free compressed air with a maximum residual oil content of a barely measurable 0.001 mg/m³ and total sterility. With this performance, the BEKOKAT units surpass even the most stringent specifications of ISO 8573-1, Class 1 oil content.
There are huge differences regarding the efficiency of oil-free compressors on the one hand and conventional, oil-lubricated screw compressors with downstream BEKOKAT treatment on the other, which makes the latter a much more cost-efficient solution. In addition, the BEKOKAT units are relatively cheap, while the compressed air treated in such systems is of a constant high quality, irrespective of the air intake conditions.
The BEKOKAT is also ideally suitable for retrofitting into existing compressor stations. Any station with existing oil-lubricated compressors can be easily turned into a supply system for oil-free compressed air.
Even if the compressed air is produced by oil-free compressors, it is no guarantee for compressed air quality which corresponds to the requirements of the residual oil classification in accordance with ISO 8573-1 Class 1 due to the intake from the surroundings. The sucked in air usually contains small amounts of oil vapour, which is then found in a concentrated form in the compressed air after the compression procedure.
