1. That is a part for keeping temperature in the pumping line, gas line and exhaust line which are used in the semiconductor industry.
2. When the temperature is kept in a suitable range, it will reduce the process powder condensing in the piping. And the user could enhance the PM cycle, so the pump and other equipment will have a longer life time.
3. Heating Jacket is an important part in the semiconductor industry , especially in the WCVD Process , Metal Etch process and LP-CVD Nitride Process . Heating jackets could solve the power condense problem easily.
