Next generation H2O2 bio-decontamination – robust and reliable process for highest operator and product safety. The H2O2 bio-decontamination system DECOpulse® with fast cycle times enabled high production times and flexibility. Very low H2O2 consumption with savings of up to 65% surety low outgassing and very low concentrations such as 0.03 ppm are quickly possible. DECOpulse® the atomization-driven evaporation system is replacing the current evaporation system DECOjet® more and more. Both systems have ads and the physical effects will explained in detail.
