Safeguarding Industrial Safety: Comprehensive Gas Detection Solutions for the Sterilization and Disinfection Industry

In modern industrial production and public health, sterilization and disinfection are critical for product quality, environmental protection, and epidemic prevention. However, effective disinfectants often carry volatilization risks, and many common disinfectant gases are strong oxidizers, toxic, or even flammable and explosive. Balancing “high-efficiency sterilization” with “operational safety” is a challenge for enterprises.

Nexisense, a global leader in gas detection technology, offers high-performance online and portable monitoring devices tailored to the sterilization and disinfection industry. This article provides a detailed overview of comprehensive gas detection solutions, including industry background, typical gas properties, installation standards, and system integration.

Why Strict Gas Monitoring is Essential in the Disinfection Industry

Sterilization uses strong oxidizers or toxic substances to destroy microbial structures. Leakage or residual gases above safe levels can cause irreversible respiratory damage or explosions.

Examples include ozone and chlorine dioxide for food packaging line purification, chlorine in municipal wastewater treatment, and sulfuryl fluoride and phosphine for fumigation in wood and agricultural imports/exports. These gases vary in physicochemical properties, requiring high sensor sensitivity, wide measurement range, and environmental adaptability.

Targeted Solutions: Deep Adaptation for Different Application Scenarios

1. Food & Beverage Production: Multi-Level Ozone and Chlorine Dioxide Monitoring

Monitoring requirements:

• Leakage warning: Online detectors (0-100ppm) in disinfectant rooms and pipelines for rapid response.

• Residual monitoring: High-precision sensors detect ppb-level traces before packaging to ensure safety.

2. Wastewater Treatment Plants: Multi-Component Monitoring

Monitoring includes chlorine (Cl₂) and by-products:

• Disinfection units: Monitor chlorine to prevent dosing system leaks.

• Pretreatment and sludge units: Monitor H₂S, NH₃, CH₄ with multi-parameter systems for real-time toxic and flammable gas detection.

  
  

3. Professional Fumigation: Capturing Highly Penetrative Gases

Gases like SO₂F₂ and PH₃ penetrate deep into storage and logistics for pest control. Specialized algorithms compensate for temperature and humidity, maintaining stable readings under extreme conditions.

Nexisense Core Technology Advantages: Designed for Precision

• Dual certification: National explosion-proof, EU CE, and RoHS certified, meeting international safety and compliance standards.

• High-performance processor: 32-bit microprocessor with 24-bit high-resolution ADC for fast sampling and minimal fluctuations.

• Full environmental compensation: Intelligent computation corrects sensor drift under temperature and humidity changes.

Scientific Installation Layout

Vertical height by gas density:

• Heavier-than-air gases (O₃, Cl₂, SO₂): install 30-60cm above ground or below leak source.

• Lighter-than-air gases (NH₃, CH₄): install 30-60cm above leak source.

Horizontal spacing: Toxic gas detectors ≤1m; combustible gas spacing ≤7.5m.

System Integration and Digital Management

Detectors connect via 4-20mA, RS485 (Modbus RTU), or wireless to Nexisense intelligent alarm control cabinets. When thresholds are exceeded, the system executes:

• Local alarm: audible/visual alerts.

• Forced ventilation: activates explosion-proof fans.

• Emergency cutoff: shuts off gas sources via solenoid valves.

• Remote push: synchronizes data to central monitoring or mobile devices.

  
  

FAQ

1. Why different ranges for ozone detectors? Higher ranges for leakage, ppb-level sensitivity for residual monitoring; customized by Nexisense.

2. Why multiple detectors in wastewater plants? Biological decomposition produces H₂S, NH₃, and CH₄, requiring multi-parameter monitoring.

3. Explosion-proof rating? SGA-500 series meets industrial standards with certified aluminum or stainless steel enclosures.

4. Calibration frequency? Every 6-12 months; shorter in harsh conditions.

5. Can link to fans or sprinklers? Yes, relay outputs allow direct control; integrated cabinets enable complex logic.

6. Installation locations? Based on gas molecular weight; heavier gases below, lighter gases above; Nexisense provides layout diagrams.
