DHP Series

Decontamination Air Locks with VH2O2

The DHP Series of pharma-grade decontamination air lock is manufactured to provide a complete turnkey solution for the bio-decontamination of heat-sensitive equipment such as packaged single-use materials, packaged drug delivery devices, empty laboratory glassware, packaged stainless steel instruments, machine parts, small stainless steel containers, electronic devices, various laboratory materials made of glass or plastic or any other material composed of parts compatible with VH2O2 to be transferred from one classified area to another.

The Steelco DHP series is available in single or double doors versions with hinged door(s) in stainless steel with glass windows. To ensure perfect tightness for safety, the unit is provided with double inflatable gaskets. Flexibility and versatility characterize the series devices available in several models and different chamber capacities – with a chamber volume ranging from 436 to 7875 liters (15 to 278 cu ft).

The vaporization process of the liquid hydrogen peroxide is performed through an onboard generator fully integrated into the technical area of the main equipment. A ventilation system guarantees a uniform VH2O2 distribution in the chamber and on the load assuring a fast aeration phase and higher throughput. Following this low-temperature treatment, the decontamination reaches the Sterility Assurance Level (SAL) values up to 10−6.

The DHP Series of pharmaceutical-grade decontamination airlock is designed, manufactured, validated, and documented according to the latest global practices and standards to facilitate customers’ compliance with current Good Manufacturing Practices (cGMPs).

Key Features

Smart Load Cell

Load cell with draft pipe and adaptable cap for any H2O2 canister available on the market.

Aeration Efficiency

Recirculation internal fan designed to reduce the aeration time of the chamber, assuring high-speed airflow and higher throughput.

Door Interlocking System

An interlocking system assures the separation of environments at different contamination levels, allowing installation in a barrier.

Maximum Safety

Fully designed with operators’ and instruments’ safety in mind. In addition, two test points ensure that no gas residues are still present and that the aeration has been adequately carried out.

Easy Maintenance

The machine is developed considering technicians’ access to the maintenance and service area – easy access to all components conforming to safety regulations.

Remote Assistance

The onboard VPN router communicates on the local network with the PLC and the HMI and allows remote connection from a computer, tablet, or smartphone without going on-site.
