The 360 degree Weir design makes these baths the most advanced heated baths available today, offering unique advantages over other solutions on the market. TTF tanks have a 45 degree chamfered scalloped weir pattern to create a uniform flow pattern that helps remove particles from the liquid surface of the process area.

The TTF series of baths delivers unequaled performance, stability, reliability, and safety. They are available in seven standard sizes and are compatible with existing standard bath controllers. Custom-size units are available on request. The combination of a time-proven heating system and improved design and manufacturing techniques makes TTF baths the longest-life unit available today.

Tiger Tanks™ Constant Temperature Baths

Designed for today’s advanced deep-submicron wafer processing, PCT’s Tiger Tank Constant Temperature Bath construction exceeds the most stringent demands of today’s wafer fabrication facilities. Tiger Tanks deliver unequaled performance, stability, reliability, longer life, and incorporate improved safety features.

• A time-proven, rugged, high efficiency heater features low watt densities for extended life. The Tiger Tank heater is intimately contacted to the vessel and covers a larger area of the vessels external surface for greater heat transfer efficiency and temperature uniformity.
• The superior insulation used in Tiger Tanks further enhances the overall thermal efficiencies of the unit, reducing external heat generated in operation and reducing electricity consumption.
• Standard fire-retardant polypropylene housing construction, FM 4910 enclosures available
• An improved and proprietary flange / seal design further extends bath life and protects against capillary action induced leakage that would normally cause corrosive heater failure, optional Hydro-seal washer further extends the life of the flange seal by adding a protective liquid barrier to eliminate acid build up around the RTV seal
• Tiger Tanks include dual redundant over temperature sensor protection; a thermocouple and thermal switch bonded to the outer wall of the vessel for optimal safety
