Catalytic converter technology for oil-free compressed air: BEKOKAT®

For highly sensitive applications, conventional compressed air processing has technical and economic limits. BEKOKAT sets new standards in compressed air processing here with pioneering catalytic converter technology. The unit fully converts hydrocarbons into carbon dioxide and water through total oxidation. The method provides constantly oil-free compressed air with a maximum residual oil content of a barely measurable 0.001 milligram per cubic metre. With this performance, the BEKOKAT units surpass even the most stringent specifications of ISO 8573-1, Class 1 oil content. A quality that is required in particularly demanding production processes. The incidental condensate from the cooling of the compressed air is also totally oil-free and can be channelled into the sewage system without treatment. 

BEKOKAT provides constant oil and germ-free compressed air and oil-free condensate

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.

The intake air for the compressed air generation is generally contaminated with hydrocarbons. Even with an oil-free compressed air generation, this therefore means that a treatment solution is required. BEKOKAT provides constant oil-free compressed air, better than class 1 according to ISO 8573-1. The catalytic converter compressed air process breaks down all hydrocarbons in the air into carbon dioxide and water. It does not matter in this case from where they originate.

Certified safety for your processes

The higher the demands on the quality of compressed air, the greater the demands for documentation. Quality management requires the use of specific devices and a corresponding independent verification. BEKO TECHNOLOGIES provides this verification by utilising elaborate tests from independent institutes, which confirm and certify the performance capability for the BEKOKAT . In association with TÜV Nord, the verification was provided under real operating conditions to confirm that compressed air treated with the BEKOKAT exceeds the specifications according to Class 1 of ISO 8573-1.

In a second series of tests with the GfPS mbH (Society for Production Hygiene and Sterility Safeguarding), it was confirmed that contaminated compressed air is germ-free when treated with BEKOKAT . After treatment, no living bacteria could be detected at all in the compressed air flow anymore. In this way, test results from two renowned testing institutes independently prove the high effectiveness of the innovative catalytic converter technology. The two certificates provide you with the required safety in compressed air treatment for your sensitive processes.

Function of BEKOKAT®

BEKOKAT makes achievable constantly oil-free compressed air with a maximum residual oil content of a barely measurable 0.001 mg/m³ of compressed air. A quality level which is required in particularly demanding production processes.

Advantages of BEKOKAT®

Compact, economical and reliable: BEKOKAT CC-018

With the BEKOKAT CC-018, the concept that has been proven for decades has now been implemented in a very compact design. This makes it possible to provide oil-free compressed air of Class 1 or better economically, even in the laboratory, directly at laser applications or for treating sensitive part air flow e.g. for breathing air supplies in painting cabins. The integrated control reliably ensures that the compressed air quality required is met at all times.

Applications with oil-free compressed air

Safe oil-free compressed air for pharmaceutical production

For the production of medicaments, the strictest hygienic standards apply to the production conditions. This of course also applies to the required compressed air. It must be absolutely free from oil in order not to contaminate the sensitive products. In its factory in Singen, Germany, drug manufacturer Nycomed relies on a comprehensive system solution provided by BEKO to treat the process air in a reliably oil-free manner.

Compressed air treatment in the beverage industry

Every hour, 150 cubic meters of purest mineral water are produced by the 14 wells of RheinfelsQuellen in Duisburg-Walsum. Enough to fill 883 bathtubs every 60 minutes – or more than 207,000 bottles. To add sparkle to the water, there is only one solution: oil-free compressed air fed to state-of-the art bottling plants and peripheral systems. The company uses an innovative catalytic process for the total oxidation of hydrocarbons in the compressed air system.

Compressed air in direct food contact at MEGGLE

Powdered lactose is pumped through pipes at Meggle AG using compressed air. The utilized conveying air has to be absolutely dry and oil-free in order to prevent clumping. This is guaranteed by EVERDRY adsorption dryers and activated carbon adsorbers from BEKO TECHNOLOGIES.

Oil-free compressed air at LAVAZZA

Two installed BEKOKAT from BEKO TECHNOLOGIES in Neuss guarantee LAVAZZA a constantly oil- and germ-free compressed air of the highest quality, which even exceeds the extremely strict requirements of ISO 8573-1, Class 1 oil content.

Surface cleaning at HELLA

Blowing of high-performance electronics via pulsating rotary jets, and tracing of plastic housings with cleaning plasma jets: At the German automotive supplier Hella, compressed air takes over the central tasks in the surface cleaning of safety-relevant components. The most important requirement in this respect: the reliable, complete absence of oil.
