  • Myth About SF6 Gas In Electrical Equipment

    Where is SF6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is SF6 a health hazard? Pure SF6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of SF6 used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*). People also ask

    Oxygen Tank vs. ConcentratorThings to Consider: Oxygen Concentrator vs. Oxygen TankFrequently Asked QuestionsYou might be aware that both devicescan deliver medical oxygen to those that require it. However,the methods of delivery, as well as the device specifications, tend to differ quite a bit beyond that. Whether you are looking at a stationary oxygen tank vs. concentrator, or whether you are interested in lightweight portable oxygen tanksor portable oxygen concentrators, it is helpful to know the differences between the two delivery systemsso you can make an educated decision with your doctor. The main difference betweenan oxygen concentrator vs. oxygen tank is in the way in which oxygen is provided. Whether it is a larger compressed oxygen tank or a small portable oxygen tankwith liquid oxygen, oxygen tanks have a finite amount of oxygen within them, which is inhaled by the user until it runs out.
