Gas detector DG-6R7/N HCF (Refrigerants), 500/1500 ppm R410A, IR sensor

Gas detector DG-6R7/N – reliable refrigerant leak detection

The DG-6R7/N gas detector is a device designed for precise detection of refrigerants (HFC) in industrial and enclosed spaces. It utilizes an advanced IR optical sensor, ensuring high measurement accuracy and a fast response time. This is crucial for ensuring safety and environmental protection in refrigeration, air conditioning, and other applications using refrigerants.

Thanks to the replaceable sensor module, this detector offers flexibility and ease of maintenance. Replacing the module does not require calibration on-site, which significantly reduces downtime and lowers operating costs. The device indicates its operating status with a built-in optical indicator, and its splash-proof housing (IP44) ensures reliability even in harsh environmental conditions.

Application and functionality

The DG-6R7/N detector is an ideal solution for monitoring the concentration of refrigerants R410A and R32 in HVACR (heating, ventilation, air conditioning and refrigeration) systems. Its applications include:

• Refrigeration installations: detecting leaks and failures in refrigeration systems.
• Air conditioning: monitoring refrigerant concentrations in air-conditioned rooms.
• Industry: controlling refrigerant emissions in production processes.
• Warehouses: protection against the accumulation of refrigerant gases.
• Air conditioning and refrigeration service: quick leak localization during repairs and maintenance.

The device works with various GAZEX control modules (MD-1.A/T, MD-1, MD-2, MD-4, MDP-1.A/T, MDP-1 PLUS, MDP-4, MDP-8, MDP-16), allowing integration with existing alarm and building management systems. Please note that the detector has a standard construction and cannot be used in areas at risk of explosion from gases, vapors or dust.

Technical characteristics and benefits

The DG-6R7/N detector is characterized by high measurement accuracy in the range of 500 - 1500 ppm for R410A (standard calibration). The IR optical sensor provides stable readings and resistance to interference. The replaceable sensor module with two alarm thresholds allows the device to be adapted to specific application requirements. This makes it possible to set different alarm levels for different threat scenarios – from warning about exceeding the permissible concentration to immediate reaction in the event of a serious leak.

Additional advantages of the detector:

• High selectivity: the IR sensor minimizes the risk of false alarms caused by the presence of other gases.
• Easy calibration: replacing the sensor module eliminates the need for on-site calibration.
• Durable construction: a high-impact ABS housing provides resistance to mechanical damage and weather conditions (IP44).
• Calibration: all detectors are calibrated in their own GAZEX Calibrating Laboratory accredited according to PN-EN ISO/IEC 17025 (PCA accreditation No. AP150), which guarantees the reliability of measurements.
• Fast response time: allows for immediate detection of dangerous gas concentrations.
