NevadaNano’s MPS™ A2L Refrigerant Gas Sensor provides accurate and reliable detection of A2L R-32, R-454b blends, R-1234yf also A1 R744 and A3 R290 and R600 refrigerants which are common in HVAC applications. What makes Nevadanano’s MPS sensor offering so different from others on the market, is its stability and long life in real-world environments.
The Refrigerant sensor is immune to poisoning, isn’t affected by rapid changes of temperature or humidity, has an extremely fast response time, self-tests for fail-safe operation and will not register false positives this means there’s NO Down-Time due to faulty refrigerant gas sensors.
With a 15+ year calibration interval and lifetime, the MPS A2L Refrigerant Gas Sensor which meets IEC/UL 60335-2-40 & ASHRAE 15 requirements, delivers industry-leading performance and the lowest total cost of ownership.
Sensor platforms:
‘S4’ (Intrinsically safe FM class 1, div 1/ Atex zone 0)
Mini (Non-Atex)
Variants within each sensor platform:
Series 3: For measurement in environments with a start-up in clean air
It will zero upon start-up and will not re-zero.
Series 4: For measurement in environments with a start-up in the presence of combustible gases.
It will NOT zero in the presence of combustible gas
Compliant to IEC 60079-29-1
Series 5 (note this is only available with the S4 platform):For measurement in environments with a start-up in the presence of combustible gases.
It will NOT zero in the presence of combustible gas
Compliant to IEC 60079-29-1
Additional certification to current global approvals: CSA 22.2 and EN 50271
Refrigerant Regulations and Refrigerant Gas Sensors
Climate change is leading to new laws restricting the use of refrigerants common in air-conditioning and refrigeration systems. Refrigerants with high Global Warming Potential (GWP) are being replaced with those with lower GWP, essentially A2Ls. Such refrigerants are thousands of times more polluting than carbon dioxide.
Residential and commercial HVAC and refrigeration equipment manufacturers are under tight deadlines to develop cooling systems to work with new low GWP refrigerants, and install leak detection systems or conduct leak detection tests per IEC UL 60335-2-40 since next-generation refrigerants such as R32, R454b are more flammable (Safety classification 2L or A2L vs 1 ) at certain concentrations in the air.
Refrigerant leak detection with the refrigerant gas sensor is a matter of both safety and environmental protection
