Catalyst System for Pure Compressed Air

Beko Compressed Air Technologies, a subsidiary of BEKO Technologies GmbH., Germany, offers BEKOKAT, a new catalyst system to ensure a constant supply of oil-free compressed air with a barely detectable max residual oil content of 0.003 milligram per cubic metre. This high level of efficiency easily sails past the stringent oil content stipulations of DIN EN8573-1/ISO 8573-1, class 1. At the same time, the new functional principle breaks down technical and economic barriers that are usually imposed on conventional compressed air treatment, especially when it involves applications with extremely high requirements. The catalyst comprises a granulate that is heated to an operating temperature of around 150?C. In the catalyst, the oil molecules are broken up until only a carbon atom remains. At the end of the final catalytic phase, the oil molecules have oxidised to H2O and CO2. The oil-free and dry compressed air can then be used for the given application; the remaining water is discharged. Consequently, BEKOKAT systems are not only highly effective, but also very environmentally friendly. The advantages further include a maximum of process reliability because catalytic oxidation takes place completely independent of ambient temperature, inlet temperature, air humidity, and oil inlet concentration. Even during partial load operation, the efficiency of the catalyst technology of the BEKOKAT device is not in any way reduced. In economic terms, the exceptionally long useful life of the special BEKOKAT granulate ? around 20,000 hours ? is somewhat of an evolutionary leap considering that conventional activated carbon fills need to be replaced after about 2.500 hours of operation.
