Danfoss announced the DST G series of A2L refrigerant detection sensors, which feature a patented inverted design. As HFC phasedown continues and A2L refrigerants become more widely adopted, the G series of sensors allows building owners and HVAC/R manufacturers to implement these new refrigerants with confidence. 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 DST G series has undergone rigorous testing in high humidity environments and under varying temperatures, and the sensors showed little or no signs of damage.
