As you can imagine, ice disables the pressure regulator. Conversion from liquid to gaseous state of a medium (e.g. LPG) requires energy<\/strong>. This is obtained exclusively from the energy supply of the environment and of the medium. As a result of this, LPG tanks and the connected fittings cool down \u2013 due to the so-called expansion cold<\/strong>.<\/p>\n You would think that only harsh minus temperatures are particularly dangerous. However, they are only to some degree, because at levels below zero, condensation produced in the tank freezes and has no effect<\/strong> on the system.<\/p>\n This becomes dangerous<\/strong> at temperatures just above the freezing point<\/strong> \u2013 mostly in combination with a high withdrawal output. Condensation is also carried away in the gas flow and enters the pressure regulator. Due to the resulting expansion cold of the gas, the pressure regulator is colder than the environment. Moisture settles, freezes and hinders the mechanical system, causes safety devices to respond or blocks the nozzle. Consequence: The output is reduced or the system goes into fault mode.<\/p>\n This can happen with both LPG tanks and cylinders.<\/p>\n To prevent icing, you can install a regulator heating<\/a> system.The regulator heating is suitable for double-stage tank regulators and 1st stage regulators. As both fittings are always installed directly on the LPG tank, the heater has an ATEX approval<\/strong> for zone 1 and 2.<\/p>\n You can find the approval in the assembly and operating manual <\/a>on our website.<\/p>\n Certain pressure regulators (e.g. type EN61)<\/a> or regulator systems can be equipped with an Eis-Ex. The Eis-Ex has the same function as the regulator heating: it heats the pressure regulator<\/strong>.<\/p>\n In addition to the internal icing of a pressure regulator described above, there is the external icing.This can happen, for example, if<\/p>\n a)<\/strong> moisture from the air initially settles as condensation water and at decreasing temperatures as white frost on the fitting.<\/p>\n b)<\/strong> water accumulates in the pressure regulator (for example in the case of buried LPG tanks) and freezes.<\/p>\n We recommend that you install the pressure regulator at an angle to the breathers<\/strong>. This way, condensation water produced can be safely drained from the pressure regulator. If the pressure reducer nevertheless ices up, the regulator heating<\/strong> helps here.<\/p>\n![\"Verhindert](\"https:\/\/www.gok-blog.de\/wp-content\/uploads\/2016\/03\/Druckregler-GOK-mit-angeschlossener-Reglerheizung.jpg\" "\\"\\"")
