Liquefied Natural Gas (LNG) has a number of advantages that are driving rapid growth. It combines the flexibility of transporting liquid hydrocarbons with high efficiency and cleanliness of the facility. The necessary infrastructure to process offshore LNG requires compliance with the most demanding requirements, both by extreme harsh conditions in which (saline environment, high corrosivity, humidity ...) develops as the danger of explosion that infrastructure must overcome installation (ATEX). In that environment, flameproof enclosures, junction boxes, terminal boxes Delvalle ATEX provide sufficient security to the installation is fully covered and is robust in terms of efficiency and effectiveness.
