Devices, apparatus, systems and methods of using a portable heater that does not use a separate compressor or blower or vacuum. The heater can be attached to a piping system to dry interior walls and/or heat coatings in the piping system. The heater can be attached to a manifold having alternative inlet end and two outlet ends. The manifold ends can have quick connect fittings with similar fittings to be easily mateably attached by rotating fittings with one another. A quick connect/disconnect air pressure regulator with quick connect fitting can be attached to the manifold ends. A quick connect/disconnect plug with similar quick connect fitting can close the manifold ends.

Devices, apparatus, systems and methods of using a portable heating unit that does not use a separate compressor or blower or vacuum. The unit can be attached to an inlet of a piping system or section and be used to dry the interior walls of the piping system or section, and/or heat coatings passing through the piping system or section, etc. The portable heating unit includes a heater attached to an inlet end of a manifold, where the manifold can include alternative inlet end and two outlet ends. The inlet and outlet ends of the manifold can have quick connect fittings that allow similar fittings to be easily mateably attached thereto by rotating the fittings with one another. A quick connect/disconnect air pressure regulator with similar quick connect fitting can be attached to anyone of the inlet and outlet ends of the manifold. A quick connect/disconnect plug or plugs with similar quick connect fitting can close off any of the inlet and outlet ends of the manifold. The portable heating unit can be used with both a separate compressor and blower/filter having vacuum generator. The portable heating unit can also be used with only a compressor. The portable heating unit can also be used with only a vacuum generator.
摘要:
A system for fluid transport at elevated temperatures having a conduit having a fluid inlet end and a fluid outlet end and at least one heating element disposed within the conduit providing direct heating of a fluid flowing through the conduit. The system is particularly suited for preventing condensable constituents of a high temperature fluid from condensing out of the fluid prior to analysis of the fluid. In addition, operation of the system so as to prevent the condensable constituents from condensing out of the fluid surprisingly does not alter the composition of the fluid.

A heater apparatus includes a main body, a detecting unit, and a control part. The main body has a power supply part to which electric power is supplied and a heating portion connected to the power supply part to generate heat by electric power supplied from the power supply part. The detecting unit detects an object around the main body. The control part controls supply amount of the electric power to the power supply part. The control part controls the supply amount of electric power to the power supply part to be reduced compared with a normal state when the detecting unit detects that the object is within a predetermined range of the main body.

An electric heating apparatus includes a power module, an electric heating unit, and a switching unit. The power module is adapted to be electrically connected to a battery for outputting electric energy. The electric heating unit includes multiple electric heating components electrically connected to the power module tor receiving and converting the electric energy into thermal energy. The switching unit is electrically connected between the power module and the electric heating unit, and is operable to control electrical connection between the power module and each of the electric heating components. Accordingly, the electric heating unit generates the thermal energy with a constant output power.
摘要:
A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.
