Ceramic Heater has leakage current of less than 10 A .
January 30, 2008 -
Offered as component for medical devices, ULTRAMIC® 600 ceramic heater can operate up to 600°C with ramp rate of up to 150°C/sec, depending on application, heater design, and process parameters. Unit allows medical devices to pass 500 A, IEC 60601, total system requirement. Available in either rectangle or ring forms, it can be machined to meet specific design requirements including holes, vacuum grooves, or ultra-fine surface finishes.
Watlow Introduces ULTRAMIC® 600, an Advanced Ceramic Heater with Low Leakage Current with Ultimate Patient Safety in Mind
St. Louis, MO (October 23, 2007) - Watlow, a St. Louis-based provider of thermal solutions, introduces its ULTRAMIC® 600 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 600 heater to meet the low leakage requirements found in medical device equipment," said Dr. Hongy Lin, principal scientist. "Numerous hours of life testing and development of proprietary techniques and practices have made all of this possible."
With a leakage current of less than 10 A, the ULTRAMIC 600 heater makes it easier for medical devices to pass the 500 A, IEC 60601, total system requirement the first time. Plus, the ULTRAMIC 600 can often eliminate a low voltage AC or DC medical grade power supply. "With less heat and weight, your electronics package can be made smaller and lighter to the advantage of your customers," added Dr. Lin.
The construction technique of the ULTRAMIC 600 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, a leakage current of less than 10 A, uniform temperatures, high durability at low mass, a rapid ramp rate and an extremely low coefficient of thermal expansion.
Watlow's ULTRAMIC 600 heater can operate up to 600°C (1112°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 600 heater is available in either rectangle or ring forms and can be machined to meet specific design requirements including holes, vacuum grooves or ultra-fine surface finishes.
