VHP Decontamination of Cleanrooms and Rooms<\/h1>\n

Shutdowns, changeovers, new-facility start-up and contamination events all call for a room-level sporicidal step. A mobile VHP generator treats the room as a sealed volume; the engineering work is in sealing, distribution and proving the result.<\/p>\n

The challenge<\/span>

Why this needs a VHP step<\/h2><\/div>\n

Room surfaces, equipment exteriors and hard-to-reach areas need a reproducible sporicidal treatment that does not depend on how carefully someone wiped. Liquid disinfection leaves residues and misses areas; fogging liquid peroxide wets surfaces and is hard to distribute evenly.<\/p>

VHP fills the sealed volume as a vapour, contacts every exposed surface, then is catalytically broken down to water and oxygen \u2014 leaving no residue to wipe off.<\/p><\/div>\n<\/div><\/section>\n\n

\n Typical configuration<\/span>

Equipment options<\/h2>\n
FG-VHP-M500<\/span>

Mobile VHP room sterilizer<\/h3>

A wheeled unit for spaces up to 300 m\u00b3. Siemens PLC and touchscreen, scheduled and remote start, optional iPad control. Moves between rooms and sites.<\/p>View specifications \u2192<\/span><\/a>FG-VHP-C1000 \/ C2000<\/span>

HVAC-integrated system<\/h3>

For multi-room suites or when the ductwork itself must be treated, a fixed system that uses the air handling plant to distribute VHP is usually the better fit.<\/p>View specifications \u2192<\/span><\/a><\/div>\n \n

\n Engineering & validation<\/span>

What to plan for<\/h2>\n
01<\/span>

Seal the volume first<\/h3>

Doors, cable and pipe penetrations, drains and ceiling grids all leak. Leaks reduce concentration inside and expose people outside. Tape or seal, and monitor H\u2082O\u2082 at the boundary during the cycle.<\/p><\/div>

02<\/span>

Isolate the HVAC<\/h3>

Supply and exhaust must be shut and dampered, or deliberately used for distribution. An uncontrolled air change dilutes the vapour and spreads it where it should not go.<\/p><\/div>

03<\/span>

Distribution beats dose<\/h3>

Corners, behind equipment and under benches are the usual failures. Fan placement, generator position and, for larger rooms, more than one injection point matter more than simply adding peroxide.<\/p><\/div>

04<\/span>

Avoid condensation<\/h3>

Cold surfaces and high humidity cause micro-condensation, which damages materials and makes kill rates unpredictable. Dehumidify first and keep the room temperature stable and uniform.<\/p><\/div>

05<\/span>

Prove it with BIs and CIs<\/h3>

Map the room with chemical indicators for distribution, then place biological indicators at worst-case locations to demonstrate the \u2265 6-log reduction for the qualified cycle.<\/p><\/div>

06<\/span>

Plan re-entry<\/h3>

Aerate until the room is below your site re-entry limit \u2014 commonly 1 ppm, the OSHA 8-hour exposure limit \u2014 and confirm with a calibrated sensor before anyone goes in.<\/p><\/div><\/div>\n<\/div><\/section>\n\n

Before you ask for a quote<\/span>

Information an engineer will need<\/h2>

Having these ready makes the first recommendation specific instead of generic.<\/p><\/div>\n

  • Room volume (L \u00d7 W \u00d7 H) and layout<\/li>
  • Equipment and materials left in the room<\/li>
  • How the HVAC can be isolated or used<\/li>
  • Room temperature and typical humidity<\/li>
  • How often the room must be treated<\/li>
  • Target time from start to re-entry<\/li><\/ul>\n<\/div><\/section>\n\n\n
    \n FAQ<\/span>

    Common questions<\/h2>\n
    How many mobile units do I need?<\/summary>

    One FG-VHP-M500 is specified for up to 300 m\u00b3. Larger or segmented spaces may need several units, extra distribution fans, or an HVAC-integrated system \u2014 distribution mapping decides.<\/p><\/details>

    Do I need to remove equipment from the room?<\/summary>

    Usually not. VHP under controlled, non-condensing conditions is compatible with many materials and electronics, but compatibility should be confirmed for the specific items, and absorbent materials should be removed.<\/p><\/details>

    Is a mobile unit or a fixed system better?<\/summary>

    Mobile suits occasional treatment of single rooms and use across several areas. Frequent treatment of a whole suite, or a need to treat ductwork, points to an HVAC-integrated system.<\/p><\/details><\/div>\n<\/div><\/section>\n
