Series 3400 Vacuum Furnace Description

The Series 3400 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 from 900°C to 1315°C max temperatures. A long list of optional equipment makes this one of the most versatile custom designed furnaces available today. The "top‐loading" design uses electric loading cranes to lower customer loads up to 2000kgs in size, and offers better ergonomics for materials that must be fired in an upright orientation.

The Series 3400 furnace line contains features only found on high-end heat treat furnaces, such as a stainless steel interior vacuum chamber, heavy duty Nichrome ribbon heating elements; and all‐metal SS radiation shields for high‐vacuum and low contamination, resistance to oxidation, fast heating and cooling, and excellent process cleanliness. You won't find any refractory ceramic insulation or graphite felt/board in this hot zone.

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 3400 furnace line is available with high‐vacuum pumping systems utilizing primarily Diffusion pumping systems, with or without cold traps and refrigerated baffles. With over 20 units in the field, the Series 3400 design is one of the most proven production designs for heat treating and annealing furnaces worldwide.
