The Series 3300 vacuum furnace design is Centorr Vacuum Industries production oriented offering for a variety of heat treatment and annealing applications. The basic design comprises a multi‐zone working hot zone available in lengths from 3‐10 meters, rated to 900°C max temperatures. A long list of optional equipment makes this one of the most versatile custom‐designed furnaces available today. The single or double‐ended varieties of this furnace offer semicontinuous operation in a high‐vacuum environment, with loads up to 1000kgs in size, and offers faster turnaround time and throughput.
The Series 3300 furnace line contains features only found on high‐end heat treat furnaces, such as a stainless steel or Inconel hot wall retort liner, heavy duty Nichrome ribbon heating elements in a refractory brick hot wall furnace; and multiple high‐vacuum systems for each processing zone. This design offers resistance to oxidation, fast heating and cooling, and excellent process cleanliness.
Standard Furnace instrumentation includes a programmable controller with PLC for process control. Name brand vacuum sensors and gauges are available on all systems as well as analog/ digital chart recorders. A full complement of program interlocks and safeties ensures safe and efficient furnace operation and reduces the chance of operator vacuum pumping errors.
The Series 3300 furnace line is available with high‐vacuum pumping systems utilizing primarily Diffusion pumping systems, with or without cold traps and refrigerated baffles. With several units in the field operating since the 1960’s, the Series 3300 design is one of the most proven production designs for Nuclear heat treating and annealing furnaces worldwide.
