    The primary workhorse for these industrial applications is our low pressure liquefaction carts for large volumes of SF6 gas, (greater than 100 lbs.). These carts find use in chambers, gas insulated pipelines and large circuit breakers transformers. The carts are completely self-contained skid-mounted units and are able to fully evacuate, liquefy, vaporize, purify and send gas back to the enclosure. They are available for stationary service or for mobile trailer applications.
