Gas Detectors DEX/F – Reliable Protection in Demanding Conditions

Gas detectors of the DEX/F series are devices designed to detect hazardous concentrations of gases or vapors of explosive liquids, toxic substances, or oxygen in enclosed spaces. They signal exceeding two alarm thresholds (A1, A2) set in a replaceable sensor module. Thanks to their explosion-proof design, these detectors can be used in potentially explosive areas, meeting stringent ATEX standards.

DEX/F detectors work with various control modules, such as MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16, and addressable modules MDD-1, MDD-1/T, and MDD-1x/T. A wide range of available sensors – semiconductor, electrochemical, catalytic, and optical – allows you to select a detector perfectly tailored to the specifics of the application.

Design and Application

DEX/F detectors are characterized by a robust explosion-proof design (flameproof enclosure) and are intended for operation in zones 1 or 2 potentially explosive with gases or flammable vapors (explosion groups IIA, IIB or IIC and temperature classes T1 to T6). The brass housing provides durability and corrosion resistance. These devices find application in many industries: chemical, petrochemical, mining, energy, ventilation and air conditioning, and anywhere where there is a risk of hazardous gas concentrations.

Advantages of DEX/F Detectors

• Safety: Meet the requirements of the ATEX Directive and PN-EN 60079 standards.
• Versatility: Available with various sensors for detecting a wide range of gases and vapors.
• Reliability: Replaceable sensor modules with compensation algorithms ensure precise measurements and long-term operation.
• Economy: Replacing sensors instead of the entire detector lowers maintenance costs.
• Easy Installation: Modular design and no need for calibration at the installation site facilitate mounting.
• High Quality: All detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025.
• Wide Range of Applications: Possibility of use in various explosion hazard zones (zones 1 and 2).

DEX-61/N is a model designed to detect refrigerants R32 or R410A in the concentration range of 1000/2000 ppm. It is equipped with a semiconductor sensor and a brass housing, ensuring reliable operation even in harsh environmental conditions. It is an ideal solution for air conditioning and refrigeration service technicians and installers of ventilation systems.
