Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down (to –161 to –164°C) to liquid form for ease and safety of non-pressurized storage or transport. In this state it is odourless, colourless, only slightly toxic and non-corrosive.
LNG is an important alternative to pipeline natural gas.
Since Natural gas is highly flammable it is required to follow most stringent safety regulations to avoid risk of explosion.
ETS engineering Spa is a worldwide leading specialist on EXPLOSION PROOF SOLUTIONS with lifting
products in compliance with ATEX directive ans IECEx regulations.
The WRH rope hoist is manufactured in accordance with the Ma-chines Directive 2006/42/EC and
the Atex Directive 2014/34/EU. IECex version, EAC certification, Norsok and UL/NEMA compliance also available.
Hoists are suitable for uses in potentially explosive areas with Eex-d & Eex-d(e) protection for Zone 1 & 2 group 2G & 3G and for Gas (IIA,IIB,IIC) and Zone 21 & 22 group 2D & 3D Dust (IIIB & IIIC) and Temperature Class T3 & T4 & T5.
The three-phase asynchronous motor with IP55 / IP66 protec-tion with insulation class F and overtemperature B allows the highest performances in the respective utilization classes.
