HP - 2500 Liquid Tube Trailer

The Liquid Tube Trailer HP2-2500 is an innovative mobile gas supply system. It's a versatile solution for a wide range of temporary applications typically supported by gaseous high pressure tube trailers in nitrogen or argon service.

With its patented on-board high pressure, high performance pressure builder and vaporizer design, the Liquid Tube Trailer precisely manages the heat for optimum gas flow while keeping the liquid cold for maximum hold time during intermittent use and reduced filling losses.
