What is an LNG Trailer?
An LNG trailer is a vacuum insulated cryogenic semi-trailer designed to transport liquefied natural gas by road. It is also known as an LNG tanker trailer or LNG semi trailer.
It plays a key role in LNG distribution systems where pipeline infrastructure is not available or economical.
