PeroxEvaporator Evaporator
Evaporator System for a Hydrogen Peroxide/Air Mixture
Gaseous hydrogen peroxide is primarily used for sterilisation and room decontamination processes in the food and pharmaceutical industries. Due to its strong oxidative effect and the formation of radicals, it has a very high elimination rate for the complete spectrum of microorganisms.
An aqueous solution of hydrogen peroxide is added to a sterile carrier air flow as finely atomised microdroplets. The aerosol produced is then fully transferred into the gas phase. Thus, the PeroxEvaporator has a flow-optimised fluid channel that is brought to the desired evaporation temperature using a central electric heating element. Due to the special design of the PeroxEvaporators, the phase change is highly controlled with maximum energy exploitation at the same time. Control of the evaporation procedure is possible via a common PID temperature controller.
In order to reduce catalytic decay, stabilisers are added to commercially available hydrogen peroxide solutions, which leads to heavy contamination of the evaporators used so far. As a result, regular time-consuming and cost-intensive maintenance and cleaning processes are necessary.
In addition, the evaporation process needs a consistent steam quality without droplets or condensate formation, since otherwise the product to treat may inadmissibly be contaminated with hydrogen peroxide.
These challenges inspired us to develop a novel evaporator that can compensate for the disadvantages of previous systems. In addition, the design principle of the evaporator allows the system to be scaled, whereby performance variants can be derived for almost all tasks.
