RINCON furnaces are designed for reliable, continuous operation at 2050 °C in production or process development environments. The Rincon furnaces process work loads from 50 lbs to 1000 lbs in hydrogen, nitrogen or inert gas. In addition, optional high vacuum systems provide ultimate pressures in the 10^-8 torr vacuum range.

The proprietary tungsten and molybdenum (or tantalum) hot zones have low thermal mass allowing rapid heating and cooling and provide exceptional temperature uniformity. The construction is rugged, clean, non-particulate, and minimizes absorption of water or volatile species evolved from the work load.

The RINCON series utilizes the time tested "bell" configuration in which the work is placed on a hearth and the heating element, radiation shields and chamber are lowered over the work. A microprocessor-based temperature programmer and programmable logic controller (PLC) provide completely automatic, unattended control with precise, repeatable results. Programs can be quickly and accurately changed from one run to the next using optional memory cartridges. These capabilities allow a variety of products to be processed with confidence.

A key feature of the Rincon Series is its ability to attain very low dewpoints. Stainless steel welded manifolds, dewpoint sensors, mass flow controlled gas streams, and -120 °C dewpoint gas dryers are available to ensure precise, predictable atmosphere control. The RINCON series furnaces are designed with the user in mind emphasizing ease of installation, maintenance, programming and operation.
