A heater-integrated filter includes: a casing in which are formed an intake port for taking in a portion of process gas from a compressor and a discharge port for discharging the process gas; a filter body which is provided inside the casing and through which the process gas from the intake port passes; and rod-like heaters which are disposed inside the casing and along which the process gas that has passed through the filter body is capable of flowing toward the discharge port along the extension direction.

A heat emitting radiator for heating a space is provided that includes a radiator panel with tubing forming a fluid circuit or loop, wherein the loop includes at least one opening for inserting a heating element that can heat a fluid in the fluid circuit. The radiator may also include a heat absorbing material, such as stone, in thermal contact with the radiator panel. The radiator can be selectively de-activated when a certain temperature has been achieved in the space or in the fluid, allowing heat absorbed by a heat absorbing material positioned within the radiator to then be radiated into the space. The radiator can then be re-activated when a selected low temperature has been reached. The heating element may be a DC electrical heating element configured to be connected to an AC power source.

A series of metallic heating elements of large sizes are presented. A conventional metallic tubular heating element is positioned into a hollow metallic profile, wherein additional high temperature resistant components are used in different assemblies, as required. A coiled resistance conductor is positioned within the interstice of two metallic tubes fitted into one another, wherein an electrically insulating powder or grit is used within the interstice, and to embed the coiled resistance conductor, and wherein additional high temperature resistant components are used in different assemblies, as required. The assemblies provide methods to reduce the use of electrically insulating powders and/or thermally conductive powders for large size heating elements, and more particularly for radiant purposes; and components are also presented to improve the emissivity of the outer surface of the radiant heating elements with a colorful look, for surface temperatures operating around and up to 500 C. to 600 C.

An electric heating device in an exhaust gas system, the device having an outer circumferential, circular, housing, wherein a rib structure is arranged in the housing. The rib structure can be heated by applying an electric current. The rib structure is arranged with rib rows parallel to one another in the housing, wherein the parallel-arranged rib rows are arranged such that they are electrically connected to one another in series or in parallel.

A limit switch assembly including a shape memory member, a furnace system for incorporating the same, and a method for controlling a furnace are provided. The limit switch assembly includes a switch communicatively connected to a control board of a furnace. The switch is configured to send a signal to the control board when actuated. The shape memory member is configured to actuate the switch. The control board, in certain instances, shuts off the furnace and arrests the supply of combustible gas when receiving the signal from the switch. The shape memory member, in certain instances, actuates the switch as a result of being heated.
