Clean Gas and Liquid Stream Heating

(BCE Mini Clean Flow)
As demand for purity increases throughout the medical, analytical, and semiconductor industries, equipment manufacturers continuously require new tools to reach the next technology threshold. In these industries electric heating applications for clean gases and liquids abound. Just a few examples are; clean air circulation, nitrogen heating, product drying, dehumidification, analytical instrument sample prep, incubation, DI water heating, solvent removal, wafer drying and processing.

High purity gas and liquid heating is challenging. Heater designs have to address problems and concerns involving contamination, thermal efficiency, electrical isolation, controllability, size, and packaging. Gas and liquid heating applications can vary dramatically. Some applications are very difficult to control and size is always a concern. One of the toughest issues to overcome is the seemingly mutually exclusive requirement for smaller size and higher power.

Driven by innovation and competition, the need for hotter, cleaner, smaller and more efficient electric heaters is unceasing. One type of heater known as the "clean flow" has broad adaptability to many clean gas and liquid heating needs. It utilizes an internal heating element isolated from the process flow chamber, both electrically and physically. Best described as a "mini circulation heater", the heater's flow chamber, with inlet and outlet connections, completely protects the clean gas or liquid from external exposure and contamination.  The internal heating element can run at fairly high watt densities to accommodate fast changing flow rates, while still maintaining a compact and efficient package.  Internal RTDs or thermocouples can be incorporated to monitor temperature closely, or to protect the heater from over-temperature.
