Clean Gas and Liquid Stream Heating

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.

In advanced technologies such as analytical, biomedical, pharmaceutical, aerospace, electronics and laboratory applications, special purpose electric heating elements are required for heating high purity fluids and gases. These applications require rugged design, fast heat-up, tight control, high temperatures and the ability to withstand exposure to harsh solvents and corrosive gases. They also must be constructed in a way to prevent contamination of the process media.

The use of standard screw plug immersions heaters, screwed into a stainless steel welded vessels (known as circulation heaters) are almost always a misapplication for these unique requirements. Circulation heaters create more problems due to leaks, material compatibility, poor controllability, and bulky size.

BCE, a northern Californian manufacturer of custom heating elements offers it's Mini Clean Flow Heater specifically for these applications. These heaters are designed for heating "clean" liquids and gases normally found in fuel cell, bio-med, laboratory, food, semiconductor and pharmaceutical applications.

The Mini Clean Flow Heater operates in a liquid or gas stream providing very fast response times and accurate control capability.

The heating elements in the Mini Clean Flow Heater are isolated electrically from the process media, protecting them from contaminants and providing long life.

Summary:
  • Designed for heating of clean gases or liquids
