Flow into A2L with efficient gas sensors for HVAC and Commercial refrigeration systems
Flow into A2L refrigerant gas detection with the new DST Gxxx refrigerant detection sensors by Danfoss Sensing Solutions, built with performance and reliability at the forefront.
DST Gxxx A2L refrigerant detection sensors
DST Gxxx A2L refrigerant detection sensors are featuring a revolutionary inverted design, which protects the sensor in harsh environments, supporting 5 different A2L refrigerants with the option of additional refrigerants added upon demand. Using Thermal conductivity, a field proven technology, our sensors meet the requirements for HVACR equipment.
With patented top-down design that protects sensors from all common contaminants you can get 15+ years of performance as estimated per our extensive internal testing.
Prioritize safety, reduce maintenance and ensure supply
Proven high-speed thermal conductivity sensors delivers excellent response time, ensuring maximum safety for users and equipment. And as a leading tech developer with in-house production, Danfoss offers a resilient supply chain, ensuring to meet your demands and maintain a steady delivery to support your business growth.
Features and benefits
Rapid and Accurate Leak Detection
Compensated over full range of temperature humidity and pressure ranges with fast response time τ63<15sec.
Eliminate False Alarms with Dewpoint Avoidance
Dewpoint monitoring and heated enclosure prevents condensation in the housing.
Immune to Dust, Oil and Water Spray
Strategic, patent-pending sensor positioning using diffusion flow principles protects sensor from exposure.
UV Protected
All exposed materials are impervious to sustained UV exposure.
No Field Service Requirements
Permanent factory calibration. No field adjustments or re-zeroing during 15+ year life as estimated per our extensive internal testing.
Minimized “Silent” Failures
Robust “full signal chain” diagnostics check for faults and integrity of signal chain.
Easy System Integration
Flexible hardware and software to customer’s application specifications.
