Enclosures for use in hazardous areas include heat exchangers for active thermal management. The enclosures are coupled to a device having heat transfer capabilities. Equipment within the enclosures produces heat within the enclosure. The heat exchanger removes heat produced from the equipment and manages the internal temperature of the enclosures to a level suitable for hazardous locations. The enclosures can be actively cooled or heated using the device.

The present invention provides systems, methods, and articles for temperature conditioning a surface. An article is formed from a first layer having a plurality of openings and a second layer having a corresponding plurality of openings. At least one interior chamber constructed and configured to retain a fluid without leaking is defined between an interior surface of the first layer and an interior surface of the second layer. At least one flexible fluid supply line delivers the fluid to the at least one interior chamber. At least one flexible fluid return line removes the fluid from the at least one interior chamber. At least one control unit that is operable to selectively cool or heat the fluid is attached to the at least one flexible fluid supply line and the at least one flexible fluid return line.

In addition, the present invention relates to a method of adjusting the temperature (60) of a vacuum chamber (102) of said vacuum system (100).

Disclosed is a jacketed, tiered baffle, bioreactor tank comprising an outer cylindrical-shaped jacket and a cylindrical tank having an inner tank surface defining a chamber configured for supporting a flexible bag disposed within the chamber, and an outer tank surface having tiered baffles configured for routing a heat exchange fluid around the entirety of the outer tank surface, the cylindrical tank disposed axially within the outer cylindrical-shaped jacket. The outer cylindrical-shaped jacket is sealed to the cylindrical tank in a manner sufficient to prevent or minimize loss of the heat exchange fluid.

A device is provided for the early detection of crack formations in work pieces or in components that are subjected to mechanical loading. Wherein in the region of at least one surface at risk of cracking there is arranged at least one testing chamber that is formed by a generative process of manufacturing the work piece or a portion of a work piece and to which a testing medium under pressure is admitted. Either a pressure sensor for determining a drop in pressure resulting from a crack formation of the work piece is connected to the testing chamber or a gas sensor that can also react to a testing medium escaping from the testing chamber in the event of crack formation is arranged in the vicinity of the testing chamber.

Disclosed is a heat exchange module for use in a chemical, pharmaceutical or biological reactor system, the module configured to be disposed in the reactor system having a flexible single use container, and including at least one thermally conductive surface adapted to contact the flexible single use container to facilitate heat transfer, and a fluid circulation path through which a heat exchange fluid can be circulated.

A microlithographic system, comprising: a climate chamber enclosing an atmosphere; a printing device for projection of an optical beam onto a photo-sensitive resist, the printing device being arranged in the climate chamber; a fluid reservoir arranged to accommodate a thermally conductive fluid and arranged to be in thermal connection with the atmosphere to transfer heat between the atmosphere and the thermally conductive fluid; a first heat exchanging means arranged outside the climate chamber; a means for transporting the thermally conductive fluid between the fluid reservoir and the first heat exchanging means; and a means for supplying a gas from outside the climate chamber to the enclosed atmosphere; wherein the first heat exchanging means is configured to transfer heat between the thermally conductive fluid and the gas before the gas is supplied to the enclosed atmosphere.
