A system for using a heated portable vacuum slurry box to efficiently store and transport material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to meet space restriction requirements at a well site while functioning within the environmental conditions of winter and summer seasons. The system includes a preferred method to unload the slurry box.

A heated portable vacuum slurry box for efficiently storing and transporting material including drill cuttings from gas and oil well sites. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The features allow for the slurry box to be meet space restriction requirements at a well site while as well as function within the environmental conditions of winter and summer seasons. Jacketed openings, stack mount systems, and a removable power unit allow for efficient use of the slurry box.

A self-contained heated portable vacuum slurry box which is constructed to hold both a positive pressure and a vacuum pressure. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The slurry box meets space restriction requirements while functioning within the environmental conditions of winter and summer seasons.

A method for establishing and/or maintaining a desired temperature of a material in an intermediate bulk container including the steps of positioning a heating element in at least partial contact with a material container containing the material within the intermediate bulk container; and applying an electrical power source to the heating element, wherein the heating element is at least partially made of a positive temperature coefficient resistant material, the heat from the heating element being largely transferred to the material in the material container.

A fluid storage tank has a base structure, perimeter columns extending upward from the base structure and a flexible bladder contained within the perimeter columns to define a boundary of the tank. The base structure is arranged to be supported on a supporting foundation to span a bottom of the tank. The upright columns are releasably coupled to the base structure and extend upward at circumferentially spaced apart positions about a perimeter of the tank in a working position of the columns. The upright columns are collapsible from the working position to a transport position in which the columns are arranged to be bundled alongside ne another. The flexible bladder is coupled to the upright columns and contains a fluid within the tank in the working position while being collapsible within the columns into the transport position.

An air composition adjustment device is provided with a cover unit including a cover that covers around a gas sensor, an inflow path that takes air into the cover, and an outflow path that causes air to flow out from the cover.

This disclosure is directed toward a heated tailgate for use in cold climates. The heated tailgate may be used with a self-contained heated portable vacuum slurry box. The slurry box generally includes a vacuum tank, a structure attached to the tank, a vertical tailgate, and a hook for pulling the slurry box onto a vehicle. The heated tailgate provides that the slurry cuttings within the slurry box which are adjacent to the tailgate do not freeze and provides for a way in which the tailgate may seal to the vacuum box.

A heated slurry transport system for receiving, transporting and unloading a cuttings slurry in a non-frozen manner in cold weather environments. The heated slurry transport system generally includes a portable tank having an interior surface, at least one wall, and a rear door. A layer of insulation surrounds at least a portion of the portable tank to help retain heat within the portable tank. A heating unit is attached to the portable tank and adapted to heat a fluid that is transferred through at least one heat loop attached to the portable tank to heat the interior of the portable tank and the contents of the portable tank.

A testing container includes a right-parallelepiped-like container, electrical components of a transformer test system which are arranged in the container and which represent a respective heat source during a testing operation, and a cooling system including at least one heat exchanger. In addition, the testing container includes a movement apparatus configured to move the at least one heat exchanger from a transport position within the container into a working position which is located at least partially outside the container. Thus, the at least one heat exchanger is movable by means of the movement apparatus from the transport position within the container into the working position which is located at least partially outside the container.

A temperature controlled container comprises exterior wall structure, interior wall structure positioned within the exterior wall structure, the interior wall structure at least partially defining an interior space configured to hold one or more products for shipping, and a chamber defined between the interior and exterior wall structure, the chamber configured to retain thermal storage medium to provide a thermally insulative layer at least partially protecting the interior space.
