Used WATKINS-JOHNSON 6CR-55(H) #9021002 for sale

WATKINS-JOHNSON 6CR-55(H) is an electric resistance oven/furnace used for annealing, tempering, stress relieving, and brazing a variety of metals and alloys. It is capable of delivering up to 55 kW of power at 480 volts and a current of 60 Amps. The oven/furnace chamber is constructed of high temperature ceramics with a stainless steel exterior. This allows for rapid heating and cooling cycles and precise temperature control. The size of the oven/furnace chamber is 20" x 20" x 16" (WxDxH) with a capacity of 15.1 cu.ft., making it an ideal choice for high volume production runs. The 6CR-55(H) has an accurate digital PID temperature controller with a range of 150°F to 2400°F (-100°C to 1050°C). This ensures precise temperature control during the heating and cooling cycles. The temperature controller also has a thermocouple input/output to allow for better accuracy and stability. The user interface allows for easy program storage and recall which helps to maintain consistent results. The controller also has open/closed ramping functions for smoother and faster application. The oven/furnace has a series of dampers and fans to provide uniform airflow throughout the chamber. This helps to create the ideal environment for heat treatments such as hardening, tempering and stress relieving. The stainless steel interior and reinforced ceramic insulation ensures fast heating and cooling times, as well as energy efficiency. The heating element is a tubular Ni-Cr alloy type, providing uniform heat distribution throughout the chamber. The 6CR-55(H) also has safety features in place to protect both the operator and the oven/furnace. The over temperature limit switch will shut off the furnace in the event of an over temperature situation. It also has a door interlock switch that will prevent it from operating unless the chamber door is properly closed. In conclusion, WATKINS-JOHNSON 6CR-55(H) is an ideal choice for heat treaters and job shops looking for a reliable and accurate electric resistance oven/furnace. It's digital PID temperature controller and robust design make it ideal for high volume production runs, and its uniform heat distribution and energy efficiency make it an economical choice. Finally, its array of safety features ensure that it is a reliable and safe piece of equipment.
