Rotary Table

Air-to-air processing advantages are combined with high throughput In this convenient to operate, space conserving design. A rotary table in the main vacuum chamber indexes each successive load from loading position to heating position and on to six (6) vacuum cooling positions - then back to the starting position for gas cooling and unloading. A remotely operated vertical ram located below the rotary table lowers (and raises) loads from (and into) the load/unload tower. A similar ram raises (lowers) loads into (from) the furnace heat zone tower. The furnace heat zone operates continuously and is always charged except during the short time when all loads are lowered to the rotary table for indexing.

Each load is cooled in vacuum on the rotary table through six (6) stations. Cooling in inert gas is possible when the load is returned to the load/unload tower just before unloading. The forced draft cooling system includes a high speed blower and a water-cooled heat exchanger to extract heat from the load, thus ensuring a safe exit temperature. The complete system is fully interlocked for automatic fall-safe control with manual override capability for maximum versatility.
