Presented is a simple, but highly energy efficient industrial heating device and method for rapid heating and high temperature gradient production whereby fermions and bosons are introduced into an adjoining fluid which may be boundary layered and consequently produce an amplifiable activated condition even at room pressure and high temperature. This heating device uses a comparatively long current carrying member which may have some curvature with penetration of the current carrying members into spaces that could have any cross-sectional geometry in a high temperature resistant stable material.

The description relates to a vehicle heating system having at least one heat transfer device through which air can flow to be heated and at least one heating device which is attached to the heat transfer device and which each involves at least one heating element arranged between two contact plates, said heating element being held by a positioning frame which is attached to one of the contact plates. The contact plates of the heating devices are each held in a positioning frame to which they are attached.

The present document describes a centrifugal ceiling fan. The fan comprises a casing, a motor and a centrifugal propeller. The casing comprises an upper surface comprising an air inlet and a lower surface comprising an air outlet. In an embodiment, the lower surface has a round bowl-like shape including a plurality of openings defining the air outlet. The propeller comprises a shaft and a plurality of blades provided around the shaft. The blades may be curved to push the air in all directions between a first direction substantially perpendicular to the rotation shaft and a second direction substantially parallel to the rotation shaft in order to evenly ventilate the room. The fan may include a heating element for heating the air as it exits from the fan.

An electric heating device for emitting a heated air flow, in particular for a sanitary room or washroom in a rail-borne vehicle, includes an air duct, a fan generating the air flow, a heating element heating the air flow and a first over-temperature switch. The first over-temperature switch can reversibly switch off the heating element when a first over-temperature is exceeded. A second over-temperature switch can irreversibly switch off the heating element when a second over-temperature is exceeded. The second over-temperature switch is disposed in a recess, depression or opening formed in the air duct. The second over-temperature switch has a disconnect or isolating switch to be thermally triggered for switching off the heating element. The thermally triggered disconnect or isolating switch can be triggered by a glass sphere or bead that breaks when the second over-temperature is exceeded.

A system and apparatus for precision temperature control of thermal bead baths used in biological laboratories to heat biological samples is disclosed. The system has an insulated outer shell and an inner shell sealed together to form a recirculation pathway. The inner shell has an air extraction port opening into the recirculation pathway and at least one air injection port opening into the recirculation pathway. A fan is in the recirculation pathway and is positioned to draw air through the air extraction port. At least one thermal sensor is connected to a control and is disposed in close proximity to one of the air injection ports. Beads used in thermal bead baths are placed in a mesh basket inside the inner shell. The fan draws air from the inner shell through the beads and into the recirculation pathway, where the air is heated by a thermal element. The air flows past the thermal element and through the air injection ports back into the inner shell.
