A refrigerated stainless steel shipping container for use in transporting and holding perishable foods in a refrigerated or frozen condition for offshore oil and gas and marine industries. The shipping container is comprised of an exterior box encasing an interior box enclosing a food refrigeration chamber. Spaced apart exterior and interior walls on the interior box create compartments for cooling material such as dry ice. Cooling material is selectively placed in the cooling compartments to control the temperature in the refrigeration chamber without electricity or other external power source. The cooling compartments are vented to the outside of the cooling container to avoid exposure of the refrigeration chamber to gases produced by dissipating cooling material. The shipping container is skid mounted and has lifting lugs for attachment to lifting slings.

A control cabinet for an exhaust gas measuring facility. The control cabinet includes a cabinet body with measuring appliances for analyzing at least one sample gas. The cabinet body includes two side walls, a bottom, a cover, a first rear wall, a second rear wall, a front side, and a channel which is arranged between the first rear wall and the second rear wall. The channel is dissipates heat. A door opens and closes the front side of the cabinet body.

A portable asphalt heater for heating asphalt includes an asphalt hopper having a floor, first and second side walls and front and rear end walls, the side walls and end walls extending from the floor and defining an opening into a cavity, the opening having an area lesser than an area of the floor, at least one door selectively closing the opening, a heating manifold including a heating chamber adjacent to and positioned beneath the floor, the heating manifold adapted to be in fluid communication with a heater assembly and adapted to direct a heated gas emitted from the heater assembly through the heating chamber and heating manifold, the plurality of chimneys in fluid communication with and extending from the heating chamber and along the first and second side walls, wherein the volume of asphalt when in the asphalt hopper is heated through contact with the asphalt hopper.

A temperature-controlled tank body having an integrated heat transfer panel is disclosed. The tank body may be mounted to a truck, trailer, or other mobile equipment and used for transporting a fluid at a temperature that is greater than that of the ambient environment. In an illustrative embodiment, the tank includes a barrel segment having a first sheet and an adjacent second sheet. The first sheet is joined to the second sheet along a first edge and a second, opposing edge. The first sheet is also joined to the second sheet at a plurality of locations between the first edge and second, opposing edge and enclosed at the ends to form a fluidly-sealed area. The tank includes a fluid inlet to facilitate pressurization of the fluidly-sealed area to generate a hydroformed cavity between the first sheet and the second sheet.

Stackable frac tanks for storing fluid which include a first tank and a second tank stackable atop of the first tank. A fluid connection device is affixed to the first and second tanks to fluidly connect the first and second tanks together. The stackable frac tanks may include a structural support frame interposed between the first and second tanks.

An insulating container comprises a container body and a container cover connected to the container body. The container both and the container cover each comprises a frame and a plate arranged on the frame. The plate comprises, from inside out, an external high strength sheet, an extruded polystyrene sheet, phase-change insulating sheets made of phase-change material, and an internal sheet. A phase-change process of the phase-change insulating sheets cooperates with a refrigeration system of the transportation device to precisely control the temperature of the insulating container and a refrigerator truck to be near a phase-change temperature. In the present disclosure, the phase-change insulating sheets made of the phase-change material remain to be in a solid state before or after occurrence of a phase change, so that the structure of the insulating container does not change with the phase change and a leakage problem of the phase-change material does not exist.

A container adapted to hold a power source, is described. The container includes a plurality of frame elements defining a plurality of corners and sides of the container. The plurality of frame elements define an interior adapted for receiving the power source and an exterior disposed of in an environment in which the container is placed. At least one power source is located in the interior and a plurality of electrical connections provided on the exterior. The electrical connections provide for connectivity to the power source. Interconnected containers are also described.

A thermal protection module includes a plurality of heat transfer elements and a medium. Each heat transfer element defines an element cavity. Each heat transfer element defines a gap with an adjacent heat transfer element. The medium is disposed within each element cavity such that the medium extends within each heat transfer element on either side of each gap. The thermal protection module has a heat flux per unit of mass in a range of 4 Watts per kilogram to 10 Watts per kilogram in free convection with a 4 degree Kelvin temperature differential.

An internal temperature adjusting device includes a heat pump, an internal heat exchanger, and an external heat exchanger. The internal heat exchanger is configured to function as one of an evaporator or a condenser of the heat pump, and exchange heat between a heat medium and air inside the container. The external heat exchanger is configured to function as the other one of the evaporator or the condenser, and exchange heat between the heat medium and air outside the container. The external heat exchanger includes a plurality of heat exchanging members separated from each other. According to the internal temperature adjusting device, drainage of the external heat exchanger as a whole can be secured.

A water supply and heating system that includes a flexible water tank, a flexible heating carpet and an electrical connection mechanism. The water tank includes a flexible outer layer and separable inflatable and collapsible water bag. The water bag is equipped with a water inlet and outlet hoses for receiving supplying water. The water bag is positioned inside the outer layer and is designed to remain collapsed when and to inflate when filled with water. The outer layer too is designed to inflate when the water bag is filled with the water and to deflate when the water is drained from the water bag. A dry space is defined between the outer layer and the water bag in which the heating carpet is positioned. The heating carpet includes flexible flat electrical heating strips that are connected to the electrical connection mechanism.
