LNG tank integrates controls, valves

A  new liquefied natural gas (LNG) fuel tank combines high capacity and easy installation for truck makers, according to Chart Industries (Nasdaq: GTLS). 

Built in a standard 26-in. diameter and measuring 108 in. long, the new tank has a capacity of more than 100 diesel gallon equivalent (DGE) allowing it to be installed in place of two tanks often used to provide sufficient range for use of natural gas in linehaul applications.  It also integrates LNG controls and valves to reduce assembly line production costs, according to Chart.

Other features include an integrated active refrigeration system that extends LNG storage time in the tank from the typical seven days to 10 days, Chart said during a press conference at the Mid America Trucking Show. 

The 100 DGE tank is a good match for the new Cummins ISX12 G natural gas engine, which is expected to be used in regional and linehaul applications, according to Paul Sjogren, Chart’s LNG global marketing manager.  Shorter length versions of the tank are also available for other vehicle configurations, he said.

While relatively new to the trucking industry, Chart has been supplying LNG fueling solutions for over 20 years, according to the company.  Sjogren pointed out that it can supply fleets considering natural gas with mobile fueling stations on wheels that can store up to 6,200 gals. of LNG, as well as larger 6,000-gal. stations in self-contained 40-ft. ISO containers.
