Vacuum Annealing High-Vacuum Furnace
The Series 3500 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 standard hot zone sizes available in lengths from 9-28 meters, rated to 900°C, max temperature. A long list of optional equipment makes this one of the most versatile custom-designed furnaces available today. The furnace chamber is mounted on wheels for servicing and maintenance. The "front-loading" design uses electric winches to drive in load cars with customer loads from 1000 - 7000kgs in size, and offers better ergonomics and temperature uniformity compared with vertical top/bottom loaders or round hot zone designs.
The Series 3500 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 3500 furnace line is available with high-vacuum pumping systems utilizing primarily Diffusion pumping systems, with or without cold traps and refrigerated baffles.
The loading station has two (2) bays, each storing one car length fabricated from Stainless Steel. The winch design allows loading of 9-28m long loads into the furnace. The load station's hydraulic or electric drive motors provide lateral movement in front of the furnace opening to facilitate loading.
With over 20 units in the field, the Series 3500 design is one of the most proven production designs for heat treating and annealing furnaces worldwide.
