Enhancing Air Duct Safety with the Det-Tronics DuctWatch IR Gas Detector

Ensuring safe and clean air in industrial and commercial facilities requires effective gas detection systems. Air ducts can carry hazardous gases that are invisible and odorless, posing serious risks to both people and equipment if left undetected. The Det-Tronics DuctWatch IR Gas Detector (PIRDUCT) is specifically designed to monitor air duct systems and provide early warning of dangerous gas levels. 

Using advanced infrared detection technology, PIRDUCT helps facilities maintain a safe working environment and comply with industry safety standards. In this article, we will explore what the DuctWatch IR Gas Detector is, how it works, its key features, applications, and the benefits it offers for enhancing air duct safety.

Why In-Duct Gas Detection is Critical for Safety

Gas detection in ductwork is not just a safety precaution; it is essential in facilities where hazardous gases may be present. Air ducts can unintentionally transport combustible, toxic, or oxygen-depleting gases from one area to another.

Because these gases are often invisible and odorless, they can spread unnoticed, putting workers, equipment, and processes at risk. The fast-moving air in duct systems means that a small leak in one location can quickly affect an entire building. Early detection is therefore critical.

Standard room-mounted detectors often miss these hazards because the gases travel through the ducts before reaching occupied spaces. This is where a dedicated in-duct monitoring device becomes essential.

The Det-Tronics DuctWatch IR Gas Detector is designed specifically for this purpose. By continuously analyzing the airflow inside the ducts, it detects dangerous gas concentrations at the source and provides timely warnings, allowing operators to take immediate action to prevent accidents.

Overview of the Det-Tronics DuctWatch IR Gas Detector

Monitoring airflow in ductwork is a proven way to enhance safety in confined and hard-to-reach spaces, especially in challenging industrial environments. The DuctWatch IR Gas Detector from Det-Tronics is designed specifically for this purpose, providing a reliable and efficient gas detection solution.

The PIRDUCT uses an optical probe that extends through the duct wall and spans the interior. This design allows moving air to flow into the detection chamber, where it is analyzed for hydrocarbon vapor concentrations. Its duct-mounted configuration makes it especially suitable for replacing existing point detectors, providing the benefits of an infrared beam detector in a pre-aligned, ready-to-install package.

One of its key advantages is sensitivity. The PIRDUCT is up to six times more sensitive to combustible gases than conventional IR point detectors, making it highly effective in situations where air stratification can reduce detection accuracy.

It delivers a standard 4-20 mA output signal proportional to 0 to 15% LFL (0-7500 ppm) methane, ensuring clear communication with control systems. The duct-mounted design not only improves response times but also simplifies installation. While it does not require field calibration, the option is available for those who need it.

Key features of the DuctWatch IR Gas Detector

The Det-Tronics DuctWatch IR Gas Detector offers design and performance features that make it both practical and effective for in-duct gas detection. Below are the key features that set it apart from other detection solutions:

  • Pre-assembled design

The PIRDUCT comes fully assembled with a sturdy aluminum mounting plate for easy installation. This reduces setup time and ensures a secure, long-lasting fit in the duct system.

  • Retrofit ready

It is designed to replace existing point-type IR detectors with minimal modification. This makes it a convenient choice for upgrades and retrofits in existing duct installations.

  • No sampling system required

The Det-Tronics DuctWatch IR Gas Detector operates without the need for expensive extractive sampling hardware. This reduces both the initial purchase cost and ongoing maintenance expenses.

  • Built-in self-testing

Built-in self-checking constantly monitors the device’s status. It automatically alerts operators to faults or fouled optics, ensuring dependable performance over time.

Typical applications of the DuctWatch IR Gas Detector

The Det-Tronics DuctWatch IR Gas Detector is suitable for a variety of industrial and commercial settings where in-duct gas detection is essential. Below are common locations where the PIRDUCT provides early detection of combustible gases: 

  • Gas turbine enclosures

The PIRDUCT detects hydrocarbon vapors within turbine systems, allowing early response to potential hazards. This helps prevent costly damage and ensures continued safe operation.

  • Gas compressor enclosures

By monitoring airflow in compressor housings, the Det-Tronics DuctWatch IR Gas Detector can quickly identify dangerous gas levels. This early detection supports proactive maintenance and minimizes safety risks.

  • HVAC air intakes

Installed in ventilation systems, the PIRDUCT can detect gas before it circulates through a building. This adds an extra layer of protection for occupants and critical equipment.

  • Engine compartment air intakes

The PIRDUCT identifies combustible gases in the airflow feeding engine compartments. This reduces the risk of ignition and extends the lifespan of machinery.
