Semiconductor Manufacturing Process
A hot water supply system for ultra-pure water that is ideally suited for point-of-use for rinsing of silicon wafers and glass substrates of liquid crystal displays.
Features
- Clean
Heating vessels through which water-flow and all plumbing pipes are respectively made of high-purity quartz glass and fluorocarbon polymer. - Compact
Slim and compact unit requires minimal foot print for installation at the point of use. - Excellent temperature control
High power of halogen lamps quickly raise the temperature and adjust it in response to variations in the water flow rate. - High efficiency
Efficiency with than 95%. - Safety
Optimum operational safety is provided through displays and sound alarms against abnormal conditions such as overheating, uncharged heating, excessive pressure and leakage of water.
