Danfoss is supporting the transition to low GWP refrigerants with its new DST G series of A2L refrigerant detection sensors, which feature a revolutionary patented inverted design.
Thermal conductivity provides the best solution for A2L gas sensing. Built with thermal conductivity technology, the DST G series excels in rapid and accurate leak detection, providing the maximum level of safety for use with A2L refrigerants. “The key advantage of building the DST G series using thermal conductivity technology, is that it allows the sensor to accurately re-calibrate itself under a wide range of operating conditions – making it the best choice for harsh environments.
Inverted design ensures optimal sensor protection and performance
Another key feature of the DST G series is the unique inverted design. This design protects the sensors in harsh environments, shielding them from dust, oil and water spray, and during pressurized cleaning and maintenance in commercial refrigeration units. All exposed materials are also UV-protected, meaning coils can be cleaned with UV light without damaging the sensor, and resulting in better indoor air quality for HVAC units.
Designed for a wide range of HVAC and commercial refrigerant applications
The sensors support five different A2L refrigerants and are designed for both HVAC applications (the DST G54B for R454B and DST GR32 for R32 refrigerants), and commercial refrigeration applications (the DST G54A for R454A, the DST G54C for R454C and the DST G55A for R455A refrigerant). Additional refrigerants are also available upon request.
