NevadaNano, Emerson to develop low global warming refrigerant gas sensing products

NevadaNano partnered with Emerson to jointly develop refrigerant gas detector products that will provide a solution to the heating, ventilation, air conditioning and refrigeration (HVACR) industry for refrigerant leak detection.

“We are proud to partner with Emerson to develop essential solutions that can help lower the impact of existing HVACR equipment on the global environment and facilitate the safe use of low GWP refrigerant gases,” said Ralph Whitten, CEO of NevadaNano.

NevadaNano’s Molecular Property Spectrometer (MPS™) technology, together with Emerson’s leading HVACR technologies experience, including flammable gas sensing products, creates a strong leadership position for gas sensing solutions. The MPS technology is a patented platform programmable for a wide range of A1, A2L, and A3 refrigerant gases such as R32, R454, and R407.

"Our solution enables original equipment manufacturers to have their product line compliant with federal HFC phasedown regulations known as the AIM act,” said John Rhodes, group president, Digital & Connected Technologies for Emerson. "The mandate shifts the industry from high GWP to lower GWP refrigerants, including mildly flammable A2L refrigerants.”

NevadaNano’s MPS outperformed all other technologies in the Air Conditioning, Heating, & Refrigeration Technology Institute (AHRTI) study (Project 9014) published August 13, 2021. The study incorporates 28 test requirements from UL, IEC, ASHRAE15, and the JRA regulatory agencies. The combined “lab on a chip” allows the sensor to pass all tests, including vibration and resistance to condensing environments and poisoning chemicals.  The Emerson gas detector will allow the HVACR industry to deploy smarter A2L systems.

The construction of world-scale natural gas processing plants by three of Africa’s top natural gas producers has attracted scrutiny, despite efforts to commercialize the continent’s hydrocarbon resources and expand energy supply on the continent.


Throughput optimization for pipelines and gas plants

Register Now

Many processes within oil and gas pipelines and processing plants depend on maintaining specific temperatures and pressures at which the process fluids are liquids or gases. In addition, anytime water is a component in the process fluid hydrates can form and plug piping and vessels. Learn how Sensia’s Throughput optimization solution allows operators, and control systems to “see inside” the process in real time to understand where the facility is operating with respect to critical physical constants, including the phase envelope and hydrate temperature. This insight allows for more stable operation, reduced energy expenditure and associated emissions, and greater facility throughput. Case studies will include controlling methanol injection, managing heaters, virtual sensors for sulfur recovery units and more.
