DHP Series
Biodecontamination air lock
The DHP Series is a validated, turnkey air lock for hydrogen peroxide vapor (HPV) biodecontamination. It is designed to support uniform vapor distribution, rapid aeration, and high throughput. This low-temperature process targets a sterility assurance level (SAL) of 10-6 for prevention of contamination.
Typical loads
Suitable for biodecontamination of a wide range of items, including:
- Packaged single-use materials
- Packaged drug delivery devices
- Packaged stainless steel instruments
- Machine parts, small stainless-steel containers
- Electronic devices
- Various laboratory materials made of glass or plastic
Double inflatable door gaskets
Independently controlled double gaskets provide a robust seal to limit leakage and support consistent containment. This helps maintain separation between areas and reduces risk from pressure loss.
Sanitary GMP construction
Built for sanitary application in regulated environments: fully drainable designs, non-retentive surfaces and 316L stainless steel with a smooth finish. Welds are ground flush and fabrication can be documented in a complete logbook. Process-contact materials with EN 10204 traceability and USP Class VI compliant elastomers.
Distribution of HPV
Hydrogen peroxide vapor is distributed through the chamber using a thermally controlled, sterile compressed-air flow. The vaporization/condensation principle concentrates HPV at the load surface to support uniform coverage and efficacy. An internal lateral air duct promotes even recirculation around the chamber and load. All piping is fully insulated and fitted with trace heating to maintain the setpoint temperature and prevent unwanted condensation.
Fast, safe aeration phase
Fresh, filtered air is injected into the chamber and piping to speed aeration. Residual HPV breaks down into water and oxygen, supporting safe, fast cycle completion.
Features
Maximum safety
Designed to prioritize operator and product safety. Dual test points verify complete aeration and the absence of HPV residues, while an interlock system supports separation between clean and contained areas in barrier installations.
Precise HPV dose control
The HPV generator doses liquid hydrogen peroxide using a weighing scale, then feeds the vaporizer to generate HPV. Dose delivery is monitored by an HPV sensor to support repeatable cycles. Liquid hydrogen peroxide is supplied from an exchangeable canister accessed from the loading side, with alerts when remaining volume is insufficient.
Non-proprietary hydrogen peroxide solution
Liquid hydrogen peroxide can be sourced from the market rather than being tied to a dedicated, proprietary consumable.
Non-proprietary components
The equipment is manufactured with proven, globally available, industry-standard components rather than proprietary parts. Original spare parts can be sourced through SteelcoBelimed with appropriate documentation and traceability or directly from original manufacturers.
