OWR SMGD Mobile Decontamination Spray System

Overview

The OWR SMGD Mobile Decontamination Spray System is an engineered field-deployable solution designed for rapid, controlled application of dry, enzymatic, and ready-to-mix decontaminants across large-scale, non-laboratory environments. Unlike conventional laboratory bottle washers or fixed-installation cleaning systems, the SMGD operates on a low-pressure spray principle—leveraging precise fluid dynamics and integrated foam generation—to deliver uniform, residue-minimized coverage over complex surfaces. Its core architecture centers on mobility, operator autonomy, and mission-critical readiness: the system integrates a self-contained generator module enabling full operational status within 60 seconds of deployment. Developed in alignment with NATO AEP-55 and CBRN response protocols, the SMGD serves as a primary tool for tactical decontamination of vehicles, heavy equipment, infrastructure assets, roadways, and high-value instrumentation where traditional aqueous washing is impractical or prohibited.

Key Features

• Integrated diesel-powered generator enabling immediate startup and uninterrupted operation for up to 12 hours on a single fuel tank
• Dedicated buffer tank with scalable capacity—sized to support full decontamination cycles for armored vehicles and large industrial assets
• Low-pressure spray manifold with adjustable nozzle configuration for optimized droplet size distribution and surface adhesion control
• On-demand foam generation module compatible with GD-6 dry decontaminant and other EN 14476-compliant enzymatic formulations
• Single-operator ergonomic interface with intuitive valve sequencing, pressure monitoring, and flow-rate feedback
• Modular chassis design compliant with ISO 22867:2021 for mobile CBRN response equipment transport and storage

Sample Compatibility & Compliance

The SMGD system is validated for use with dry decontaminants (e.g., GD-6), enzymatic solutions meeting EU Biocidal Products Regulation (BPR) Annex I criteria, and ready-to-use liquid formulations conforming to ASTM E2613–22 for surface decontamination efficacy. It does not require connection to external water or power infrastructure, eliminating dependency on municipal utilities or fixed facility utilities. While not classified as a medical device under FDA 21 CFR Part 820 or EU MDR 2017/745, its operational parameters align with GLP-relevant documentation practices for field-based decontamination logging—including time-stamped event records, agent batch tracking, and environmental ambient condition capture where interfaced with optional data loggers.

Software & Data Management

The SMGD operates via electromechanical controls without embedded firmware or network connectivity; however, it supports integration with third-party digital logging platforms through analog output signals (4–20 mA) for pressure, flow rate, and generator runtime. Optional Bluetooth-enabled sensor modules (sold separately) provide real-time telemetry to Android/iOS tablets running OWR’s FieldLog Pro app—enabling audit-ready reporting per ISO/IEC 17025:2017 clause 7.9 on result reporting and traceability. All manual logs generated during operation comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) when completed using standardized OWR Form DC-07.

Applications

• Tactical CBRN decontamination of military vehicles, aircraft ground support equipment, and command shelters
• Rapid response decontamination of public infrastructure following chemical release incidents (e.g., transportation corridors, rail yards)
• Field maintenance of high-precision optical and electronic test equipment where aqueous exposure poses corrosion or calibration drift risks
• Pre-operational decontamination of robotic platforms and UAVs prior to sensitive mission deployment
• Support of ISO 14644-1 Class 5–8 cleanroom commissioning where dry-agent surface conditioning precedes particle count validation

FAQ

Is the SMGD certified for use with FDA-regulated pharmaceutical manufacturing equipment?
No—the SMGD is not intended for GMP cleanroom applications involving direct contact with drug product contact surfaces. It is designed for gross decontamination of structural and vehicular assets.
Can the system be retrofitted with automated dosing control?
Yes—OWR offers the SMGD-DAC add-on kit (Delivery Automation Controller), which adds programmable peristaltic metering and agent concentration feedback via inline conductivity sensing.
Does the SMGD meet NFPA 472 standards for hazardous materials response?
It complies with NFPA 472 Chapter 9 (Decontamination Equipment Requirements) for mobile, self-sufficient systems when operated with approved agents and maintained per OWR Maintenance Bulletin MB-SMGD-2023.
What is the expected service life under continuous field deployment?
With biannual preventive maintenance per OWR Service Manual SM-SMGD-Rev.D, the system demonstrates ≥15,000 operational hours across temperature ranges from –25 °C to +55 °C.
Is training provided for operators and maintenance personnel?
OWR delivers certified instructor-led training (Level I–III) aligned with ICS-100/200 frameworks, including hands-on drills, documentation review, and scenario-based competency assessment.
