How PST Oxygen Analyzers Improve Safety and Efficiency in Painting and Coating Production

Painting and coating production processes often involve using flammable solvents and volatile organic compounds (VOCs), creating an inherent risk of combustion. Without proper monitoring and control, excessive oxygen levels can lead to dangerous and costly incidents, including flash fires and explosions.

To mitigate these risks while maintaining operational efficiency, manufacturers implement inerting systems using nitrogen displacement to control oxygen levels. However, the effectiveness of these systems depends on precise monitoring.

This is where PST's advanced oxygen analyzers, such as the Oxy-One and GPR-1800AIS and GPR-2800AIS play a critical role.

By continuously measuring oxygen concentrations, these devices help ensure that levels remain within safe thresholds, safeguarding personnel, equipment, and product quality.

The Role of Inerting

Inerting introduces an inert gas, typically nitrogen, into the production environment to lower oxygen levels below the limiting oxidant concentration, effectively preventing combustion.

In painting and coating applications, inerting systems are vital during vessel cleaning, where oxygen, flammable solvents, and potential ignition sources can create hazardous conditions. By displacing air in the vessel, nitrogen reduces oxygen levels, ensuring safe maintenance and cleaning without the risk of combustion.

Additionally, inerting is crucial in other painting and coating production stages, such as storage and application processes. In storage tanks, maintaining low oxygen levels prevents the degradation of coatings and solvents, preserving their chemical properties and extending their shelf life. During the application phase, controlled oxygen levels prevent unwanted oxidation, impacting the finish quality and durability of coatings.

The efficiency of inerting systems depends on precise oxygen level control, achieved through integrating oxygen analyzers. These analyzers provide real-time measurement, allowing for adjustments to nitrogen flow rates to ensure oxygen levels remain safe throughout the process. Advanced monitoring systems also help detect leaks or fluctuations in oxygen concentration, enabling prompt corrective actions and preventing potential hazards. Manufacturers can enhance safety, maintain regulatory compliance, and optimize resource usage by implementing a reliable inerting system with continuous oxygen monitoring.

The Importance of Oxygen Analyzers

Oxygen analyzers are essential for maintaining safe and efficient inerting in painting and coating production. They provide continuous, real-time oxygen measurements, enabling manufacturers to keep oxygen levels safely below combustion thresholds.

PST’s advanced analyzers, such as the Oxy-One Oxygen Inertization System, offer next-generation monitoring with multi-sensor inputs, automatic control functions, and configurable alarms. These systems not only measure oxygen levels but also trigger corrective actions like nitrogen injection or ventilation if thresholds are exceeded — reducing reliance on manual intervention and minimizing the risk of human error.

With features like auto-calibration and built-in diagnostics, PST analyzers ensure long-term accuracy and reliability, helping manufacturers enhance safety, maintain regulatory compliance, and protect product quality.
