Centorr Vacuum Industries (CVI) announced it is completing the manufacture of a 92-foot-long precision vacuum annealing furnace for straight tubes and U-tubes for use in nuclear power stations. The furnace is based on proven designs previously sold worldwide by CVI for vacuum tube annealing and degassing. The current furnace was upgraded to include a new control system and improved high-vacuum pumping system. The unit is rated for operation at approximately 1300°F in high vacuum and has a 15,432-pound capability per load.

CVI, located in Nashua, N.H., has been providing this type of furnace to the nuclear industry since the 1970s. The company offers furnaces ranging from large commercial and production units to smaller laboratory furnaces for use at temperatures over 5400°F.
