Good News! MemsFrontier A2L Refrigerant Leakage Detection Sensor Has Obtained The IEC UL Certification

Recently, the A2L refrigerant leakage detection sensor developed by Shenzhen Memsfrontier Electronics Co., Ltd. ( referred to as "MFrontier") was awarded by TÜV Rheinland Greater China (referred to as "TÜV Rheinland"), a third-party testing, inspection and certification agency. The IEC UL certification reflects TÜV Rheinland's high recognition of MFrontier laboratory testing capabilities, management system, and refrigerant sensor product development level and quality.

Since the signing of the Montreal Protocol in 1987, the heating, ventilation, air conditioning and refrigeration (HVACR) industry has gradually shifted to the use of third- and fourth-generation refrigerants with lower global warming potential (GWP) to adapt to the Montreal Protocol. Kigali Amendment Requirements for Global Greenhouse Gas Emissions Reduction. Many third- and fourth-generation environmentally friendly refrigerants with excellent performance and low GWP (global warming potential) have certain toxicity and flammability.

At the same time, safety standards for products related to refrigeration, air conditioning and heat pump equipment such as IEC/UL 60335-2-24 (refrigeration and refrigeration appliances), IEC/UL 60335-2-40 (heat pumps, air conditioning systems and dehumidification systems), IEC/UL 60335-2 -89 (commercial refrigeration and refrigeration appliances), etc. All require that components within the product that may be a source of ignition must have relevant safety levels, or have flame-proof capabilities for the type of refrigerant used to ensure that flammable refrigerants are not leaked. This component will not become a source of ignition and cause an explosion resulting in property damage or casualties. Therefore, more and more national regulations require HVAC appliance manufacturers to reduce greenhouse gas emissions from products, monitor leaks of flammable refrigerants, and ensure the safety of flammable refrigerants. This is becoming the core part for HVAC R equipment testing, evaluation and certification. 

In order to ensure the safety of A2L refrigerant in the heating, ventilation, air conditioning and refrigeration (HVACR) industry, IEC/UL 60335-2-40 covers the detection accuracy, response time, and performance of A2L refrigerant gas leakage sensors in high temperature, high humidity, and different air pressure environments. Oil mist interference, cross-gas interference, high-concentration gas impact, long-term work, ignition testing and other harsh environments have put forward strict requirements on the stability and service life of the product.

MFrontier A2L refrigerant detection sensors pass IEC/UL (60335-2-40 Appendix LL) dual certification. Adopting the principle of NDIR (Non-dispersive infrared) technology, gas monitoring has high selectivity and is not susceptible to cross-interference by mixed gases. High detection accuracy and low detection threshold, which can detect gas leak abnormalities earlier while avoiding false alarms. High long-term stability, easy to use with a lifespan of 15 years and low maintenance costs.  It is an ideal technical route for monitoring flammable refrigerant leaks in the heating, ventilation, air conditioning and refrigeration (HVACR) industry.

MFrontier adheres to the business philosophy of "quality first, customer first, sincerity and perfection" and focuses on using advanced sensor technology and solutions to help customers continue to create value. We look forward to providing services to many heat pumps, air conditioning systems, HVAC, refrigeration systems around the world, Unit manufacturers.
