In an oil storage tank having an interior oil storage chamber and a tank opening in one of the boundary walls, a heating assembly is supported to extend into the interior oil storage chamber from the tank opening. The assembly includes a casing of walls surrounding with a casing mounting flange mountable in sealing engagement relative to a tank mounting flange about the full perimeter of the tank opening such that the casing protrudes into the interior oil storage chamber of the oil storage tank. The heating chamber is suitable sized and configured to operably receive a catalytic heater therein. The heating chamber further accommodates entry of combustion air and combustion fuel into the heating chamber and exhaust of emissions therefrom.

A powder container (10) comprising a pressure vessel (12) for containing a quantity of powder (14) and a quantity of pressurised gas (32), an outlet through which, in use, the powder (14) can flow out of the pressure vessel (12), and an outlet valve (24) for selectively opening and closing the outlet, wherein the container (10) further comprises a data sensing and/or logging means (56, 58, 60, 62, 64) adapted to monitor and/or log various parameters of the powder (14) and/or the pressurised gas (32) and further comprising a control unit (54) adapted record and log the sensor readings either continuously, or at intervals, the control unit (54) comprising a communications module adapted to relay sensor readings, or log files, to a remote monitoring station.

A refrigerated cargo container includes a cargo container and a refrigeration unit. A plurality of refrigerant tubes are in fluid communication with the refrigeration unit and extend along a roof of the cargo container. The plurality of refrigeration tubes are configured to convey refrigerant there through and cool an interior of the cargo container via natural convection and thermal radiation. A method of cooling a cargo in a cargo container includes flowing a refrigerant through a plurality of refrigerant tubes disposed at a roof of the cargo container. Thermal energy is transferred from container air in the container to the refrigerant thereby cooling the container air. The container air is circulated via natural convection toward the cargo thereby cooling the cargo via thermal energy transfer to the container air. The container air is recirculated toward the plurality of refrigerant tubes.

A container refrigeration device aims to prevent low temperature damage to freight in a container. The container refrigeration device includes: a temperature controlling section (101) configured to perform, in a switchable manner, first temperature control under which a temperature inside the container (C) is controlled based on a blown air temperature (Tss) and second temperature control under which the temperature inside the container (C) is controlled based on a suction air temperature (Trs) during dehumidification operation; and a control switching section (103) configured to switch the first temperature control to the second temperature control when the blown air temperature (Tss) is higher than the suction air temperature (Trs) during the dehumidification operation in which part of a refrigerant discharged from a compressor (30) is allowed to flow into a reheat heat exchanger (83).

Vessel assemblies, heat transfer units for prefabricated vessels, and methods for heat transfer prefabricated vessel are provided. A heat transfer unit includes a central rod, and a plurality of peripheral rods surrounding the central rod and connected to the central rod. The plurality of peripheral rods are movable between a first collapsed position and a second bowed position, wherein in the second bowed position a midpoint of each of the plurality of peripheral rods is spaced from the central rod relative to in the first position. The heat transfer unit further includes a heat transfer element connected to one of the plurality of peripheral rods.

This invention is directed toward a self-contained heated portable vacuum slurry box which is manufactured from steel rated for cold temperatures. The slurry box generally includes a vacuum tank, a structure attached to the tank, a mechanical bay containing a power unit, and a tailgate, a The invention herein utilizes a selection of steel that allows for a vacuum slurry box to function in the cold environmental conditions.

A transportable refrigerated container has an interior chamber sub-divided into separate compartments by movable partitions that allow free air circulation to maintain the compartments at the same temperature and a plurality of security doors in at least one of the sides of the container, each door affording access only to a selected respective compartment or group of compartments. A method of distributing perishable goods from a supply depot to a plurality of customers utilizes such a container. At the supply depot, goods for different customers are loaded into separate compartments and the container is then transported to a location convenient to all the customers. There, delivery drivers who can each only open a door leading to a compartment containing goods intended for a specific customer, transfer the goods from the compartment onto a smaller vehicle and deliver them to their respective customer.

The invention relates to an apparatus for heat treatment of motor vehicles or motor vehicle parts, in particular for the purpose of killing pests, comprising art insulated sea freight container for temperature-controlled transport, the apparatus comprising at least one fan and at least one heat exchanger in addition to a cooling assembly which is possibly arranged in the container and is possibly capable of functioning.

Methods and systems for the production and delivery of lithium metal of high purity are provided. More particularly, methods and systems for lithium metal purification, delivery and deposition are provided. In at least one aspect, a liquid lithium delivery system is provided. The liquid lithium delivery system comprises a liquid lithium delivery module. The liquid lithium delivery system comprises a lithium storage region operable to store the liquid lithium, a pumping region operable to move liquid lithium through the lithium delivery, and a flow control region. The pumping region comprises an electromagnetic pump operable to move the liquid lithium using electromagnetism. The flow control region operable to control the flow of liquid lithium, comprising one or more valves operable to control the flow of the liquid lithium, wherein the pumping region is positioned downstream from the lithium storage region and upstream from the flow control region.

A method of connecting a heat exchanger, which is used primarily in oil and gas operations to heat tanks of liquids, such as drilling mud, water, heavy oil or other such fluids from freezing or becoming too viscous to pump, to a tank.
