NevadaNano, a gas sensor manufacturer based in Sparks, Nevada (U.S.), has announced new gas sensors that can detect A3 (flammable) refrigerants, including propane (R290) and isobutane (R600a), as well as A2L (mildly flammable) and A1 (nonflammable) refrigerants, in one unit.
The detectors employ what the company calls a Molecular Property Spectrometer (MPS), which was developed at the University of Nevada, Reno, and supported by DARPA (Defense Advanced Research Projects Agency) the U.S. Department of Defense (DOD), and the U.S. Department of Homeland Security.
According to NevadaNano, the new sensors:
• Avoid the need to use and maintain multiple sensors in a single location or application.
• Avoid “drift and false-positive alarms.”
• Don’t stop working when exposed to common household and industrial chemicals.
The sensors can be used for residential and commercial HVAC; data center cooling; commercial, grocery store, and cold chain refrigeration; and transportation and processing refrigeration.
The sensors can help users adhere to new global standards for cooling/refrigeration applications, the company said.
