NET Cyber Heads have been recently declared conform to Annex LL of IEC 60335-2-40:2018. This short article will explain in greater details the content of Annex LL and what are the requirements of refrigerant detection systems for flammable refrigerants for household and similar electrical appliances. The IEC 60335-2-40 standard deals with the safety of electric heat pumps, sanitary hot water...
IEC 60335-2-40 is presently being used as the basis for the design, evaluation, testing and certification of HVAC equipment using Low GWP refrigerants (A1, A2L, A2 and A3 as defined by ISO 817). IEC 60335-2-40 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units,...
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Different Hydrocarbons have different number of atoms and molecular structure, but in most cases, they can be detected in a common area of the Infrared Spectrum, between 3.0 and 3.5 microns. In other words, a certain degree of cross-sensitivity exists between different hydrocarbon gases as...

The most complete range of refrigerant leak detection sensors on the market based on NDIR technology adds yet another option for its users: R-22 in ppm range. Also known as Chlorodifluoromethane or difluoromonochloromethane, R-22 has been phased out under the Montreal Protocol in developed countries in 2020 due to its ozone depletion potential (ODP) and high global warming potential (GWP),...

Please, remeber to send your purchase orders only to the following address: orders@nenvitech.com. Sincerely, The...
NET offers a strong range of electrochemical cells for the detection of the most common toxic gases, including CO, H2S, CL2, SO2, NH3… in different safety applications. This very cost-effective technology has been used in the industry since the 1960s. Users often ask us clarification about 3 important parameters and the differences among them: cell life, storage life and...
Over the years, NET has determined cross factors allowing specific IREF PRO sensors - notably, R-125, R-134a, R-32, R-507, R-1234yf and R-1234ze sensors - to be used when detecting multiple other refrigerant gases, including some gases for which a dedicated sensor is not available yet from NET. This feature is extremely useful for user who wants to rationalize their P/Ns...
