How to Specify a Portable VPHP Decontamination System

Buying a portable VPHP decontamination system is not a smaller version of buying a fixed installation. The operating model changes: the system may travel between sites, be used by different teams and operate without permanent facility integration.

The specification should protect the process outcome, not merely list device features.

Define the mission first

Document what must be treated, where it will operate and why. Identify the enclosed equipment, biological objective, frequency of use, likely deployment conditions, access restrictions and expected turnaround. This prevents a common mismatch: selecting a portable device based on size or price without proving that it supports the required workflow.

Procurement checklist

Ask suppliers to address the following points:

• Delivery and distribution: how is VPHP generated and delivered to the intended equipment?
• Cycle control: which parameters are controlled, recorded and visible to the operator?
• Monitoring and aeration: how are residual vapour and safe release managed?
• Validation support: what evidence, indicator strategy and requalification pathway are available?
• Operational fit: setup burden, remote operation, alarms, training, maintenance and service response.
• Deployment logistics: transport classification, consumables, storage, power requirements and field support.
• Data and traceability: cycle identification, operator records, deviations and exportable reports.

Why solid-state delivery can matter

For deployed operations, the handling and transport model can be as important as the active agent. DeloxHP is a proprietary solid formulation designed to release hydrogen peroxide vapour in a controlled manner. Its solid-state format also avoids the need to handle concentrated liquid hydrogen peroxide during routine deployment, potentially simplifying transport, storage and on-site preparation while reducing the risks associated with spills and direct contact with concentrated liquid formulations.

Turn a demonstration into evidence

Do not accept a generic demonstration as proof of suitability. Agree the target equipment, workflow, monitoring locations and success criteria beforehand. Include the people who will operate, maintain, approve and procure the system.

Then connect the assessment to Portable vs Fixed VPHP Decontamination Systems and How to Validate Portable VPHP Before Field Deployment.

Request a procurement assessment

Request a technical procurement assessment from Delox for your equipment, sites and deployment model.

Evidence basis

The procurement criteria in this page reflect published findings that delivery method, monitored parameters, environmental conditions and indicator strategy influence decontamination outcomes [1-3]. Demonstration and validation should remain specific to the intended application.

Frequently asked questions

What should a portable VPHP system record?

Useful records normally include cycle identity, operator, phase timings, controlled parameters, alarms, deviations and release status. Exact requirements depend on the application and quality system.

Why is a site-specific demonstration important?

It tests whether the system can meet the intended application, not merely whether it can run a cycle under generic conditions.
