Gas Detectors DEX/F – Reliable Safety in Any Environment

The DEX/F series gas detectors are advanced devices designed to detect hazardous concentrations of gases and vapors in various industrial and commercial environments. Thanks to their explosion-proof design, these detectors provide safe and continuous protection against fire and explosion hazards, as well as the effects of exposure to toxic gases. These devices are compatible with GAZEX control modules, enabling the construction of comprehensive detection and alarm systems.

Wide Range of Applications and Detected Gases

DEX/F detectors are used in many industries, such as the chemical, petrochemical, mining, energy sectors, as well as in public utility facilities. Models with various sensors are available, allowing for the detection of a wide range of gases, including:

• Methane (CH4) – a key parameter in gas installations and production processes.
• Flammable gases (LPG) – propane-butane, important in warehouses and heating installations.
• Ammonia (NH3) – used in refrigeration and the chemical industry.
• Carbon monoxide (CO) – a colorless and odorless toxic gas produced during combustion.
• Hydrogen (H2) – used as a fuel and in industrial processes.
• Carbon dioxide (CO2) – monitored in ventilation and climate control systems.
• Organic compounds - important in industrial processes and when working with solvents.

Design and Characteristic Features

DEX/F detectors are characterized by a robust explosion-proof design, meeting the requirements of the ATEX Directive. Made of high-quality materials, such as nickel-plated brass or oxidized aluminum, they provide durability and corrosion resistance. Replaceable sensor modules allow for easy calibration and maintenance, as well as adaptation of the detector to specific application needs. Additionally:

• Models with semiconductor, catalytic, electrochemical and optical (Infra-Red) sensors are available.
• Detectors work with GAZEX alarm modules of type MD-1, MD-2, MD-4 as well as more modern MDP and MDD series.
• Modular construction simplifies the design and installation of gas detection systems.
• All detectors are calibrated in their own GAZEX Calibration Laboratory in accordance with the PN-EN ISO/IEC 17025 standard.
• Wide operating temperature range ensures reliable operation even in harsh environmental conditions.

Installation and Operation

Installation of DEX/F detectors should be carried out by qualified personnel in accordance with the operating instructions and applicable safety regulations. The location of the detector should take into account the physical properties of the gas being detected (e.g., heavier gases accumulate near the floor). Regular calibration of detectors is crucial to ensure their correct operation and measurement reliability. Replacement of sensor modules should be performed in accordance with the manufacturer's recommendations or after a specified period of operation.
