The DECOjet® technology of Metall + Plastic combines direct injection nozzles in the manipulation unit with the H2O2 gassing between the CG membrane and HEPA filter. Based on CFC simulations, H2O2 will be introduced at places that have low H2O2 concentration. The result is a defined and quick distribution of H2O2 while, at the same time, using a reduced amount of H2O2. Metall + Plastic filed a patent for this technology, that decreases the injection time thus resulting in a reduction of up to 50 percent of the decontamination time for the entire decontamination cycle. This means pharmaceutical machinery is available for production much faster. In addition, the reduced H2O2 quantity is saver for the material. The DECOjet will also minimize the gas release effect and can be retrofitted in Metall + Plastic isolators that are designed according to the “open loop” principle or integrated in new isolators.
Studies confirm the effectiveness of the DECOjet technology: during a customer project the H2O2 injection phase was reduced from 57 to 33 minutes and the total consumption was reduced by 43 percent. A comparison of 39 identical BI- locations that were decontaminated with and without the DECOjet technology in a manipulation unit, resulted in a worstcase locations, in average D-values of 5.7 minutes with the conventional process and 3.3 minutes with the DECOjet technology.
