Nebulization of hydrogen peroxide by modular preparation system

Virus­es, bac­te­ria and fun­gal spores are omnipresent and must be reli­ably killed for sen­si­tive process­es in the phar­ma­ceu­ti­cal and food indus­tries or biotech­nol­o­gy. A residue-free dis­in­fec­tant such as hydro­gen per­ox­ide is ide­al for this pur­pose. To ensure that this works reli­ably in prac­tice, Bürk­ert Flu­id Con­trol Sys­tems has devel­oped a scal­able sys­tem for chem­i­cal dis­in­fec­tion with a com­pressed air-dri­ven dual-sub­stance noz­zle that ensures homo­ge­neous and fine aerosol for­ma­tion with min­i­mal chem­i­cal and ener­gy input, thus meet­ing the high­est dis­in­fec­tion stan­dards. Fine­ly dis­trib­uted, hydro­gen per­ox­ide evap­o­rates and has a par­tic­u­lar­ly strong cor­ro­sive and cyto­tox­ic effect, as well as a dis­in­fect­ing effect due to its strong tox­i­c­i­ty to many germs. The wide, inde­pen­dent con­trol range for air and liq­uid vol­ume allows many dif­fer­ent set­tings for through­put and atom­iza­tion rates. This makes the sys­tem indi­vid­u­al­ly tun­able, very flex­i­ble and suit­able for a wide range of appli­ca­tions such as ster­il­iza­tion of pack­ag­ing, HEPA fil­ters or for room disinfection.

Reliable results with minimal use of disinfectants

30 to 35% hydro­gen per­ox­ide is deliv­ered by over­pres­sure from a stain­less steel reser­voir to a liq­uid flow con­troller (LFC), which pre­cise­ly reg­u­lates the amount of liq­uid. In par­al­lel, the atom­iz­ing air is pre­cise­ly metered to the noz­zle via a mass flow con­troller (MFC). This takes over the atom­iza­tion of the liq­uid phase from fine droplets to the finest mist, which then evap­o­rates eas­i­ly. Pre­cise mea­sure­ment of the sub­stance flows allows the dis­in­fec­tion dura­tion to be pre­cise­ly defined, sav­ing time and dis­in­fec­tant with exact­ly repro­ducible dis­in­fec­tion results.

All para­me­ters such as dura­tion and amount of sub­stance can be export­ed and stored dig­i­tal­ly for qual­i­ty assur­ance. The dis­in­fec­tion sys­tem has a mod­u­lar design and is avail­able in var­i­ous ver­sions. Depend­ing on cus­tomer require­ments, vari­ants with an addi­tion­al heater or an inte­grat­ed flush­ing sys­tem are avail­able in addi­tion to the basic ver­sion with noz­zle, stor­age tank, and con­trollers and meter­ing valves with match­ing pip­ing. If required, the scal­able com­plete mod­ules also include inte­grat­ed safe­ty equip­ment or com­plete con­trol cab­i­net inte­gra­tion with PLC control.
