Watlow Introduces ULTRAMIC® 600 Advanced Ceramic Heater with an Exceptionally Fast Ramp Rate in a Small Durable Package
July 17, 2007
St. Louis - Watlow, a St. Louis-based provider of thermal solutions, introduces its ULTRAMIC® advanced ceramic heater. The high thermal conductivity aluminum nitride (AIN) ceramic composition is paired with a proprietary, thermally matched, heating element to enable a fast responding heater configured in a low mass package.
"Watlow's R&D team developed the ULTRAMIC heater to meet the requirements found in challenging industrial applications," said Dr. Hongy Lin, principal scientist. "Numerous hours of life testing and development of proprietary techniques and practices made all of this possible."
The construction technique of the ULTRAMIC heater is to sinter the ceramic at elevated temperatures to create a monolithic, geometrically stable structure. The result is a very low porosity, homogeneous, robust heater assembly that provides the necessary heat transfer for high temperature and long heater life.
Constructing an electric heater using sintered ceramic materials provides many benefits including high dielectric strength, low leakage current, uniform temperatures, high durability at low mass, a rapid ramp rate and an extremely low coefficient of thermal expansion.
Watlow's ULTRAMIC heater can be operated up to 400°C (752°F) with a ramp rate of up to 150°C (270°F) per second depending on the application, heater design and process parameters. This heater also contains a unique (patent pending) integrated thermocouple configuration that improves the reliability of the sensor/heater interface to ensure fast responsiveness during high ramp rate applications.
Watlow's ULTRAMIC heater can be designed and manufactured in two-dimensional flat or ring forms. Plus, the ULTRAMIC heater can be machined to meet specific design requirements including holes, vacuum grooves, fine surface finishing and other two-dimensional geometric features.
The ULTRAMIC heater can be used in semiconductor processing, wire and die bonding equipment, analytical instrumentation, aerospace and medical device applications.
