CENTORR VACUUM INDUSTRIES LLC. OFFERS
VACUUM FURNACE UPGRADES FOR
IMPROVED PERFORMANCE AND LESS DOWNTIME!
THESE UPGRADES WILL SAVE YOU TIME AND MONEY!
 WATER SYSTEM:
  1. The old water system has a paddle flow switch and flow indicator that sticks in the open position, which is a safety issue.
  2. New System - Advantages of Digital Flow Systems:
    • Longer life of flow sensor compared with Flotek brand sensors.
    • No moving parts in flow sensor, therefore less sensitive to Calcium Oxide and other mineral buildup typical in "flapper" style flow sensors.
    • Provides for direct visual feedback of water flow with "red light/green light" indicator lights on each individual sensor - greatly helps with troubleshooting water flow problems.
    • No glass site windows that get clogged, or discolored after 1-2 years.
 HOT-ZONE GRAPHITE:
  1. Old design, hot zone graphite felt with graphite yarn sewn to stainless steel body, doors, etc.
  2. New design single or multi layered rigid graphite board fastened with CFC threaded rod and HLM nuts. For a harsh environment, add CFC plate on the hot-face to protect the rigid graphite board.
 PNEUMATIC SYSTEM:
  1. Old design, Humphrey air valves on manifold.
  2. New design, SMC air valve on air manifold for half the cost and less downtime.
 PYROMETER TEMPERATURE SENSING SYSTEM:
  1. Old design, one (1) color and two (2) color pyrometer temperature sensing system with gray box, etc. that are not as accurate as the new style pyrometer.
  2. New design, two (2) color pyrometer temperature sensing system which is more reliable, and accurately reads temperature directly on the controller. C/VI will also offer an auto T/C cross-over combination T/C to the OP.
 VACUUM INERT GAS FAN COOLING SYSTEM:
  1. C/VI offers several sizes, 2Hp, 5Hp, 10Hp, and 25Hp Vacuum Inert Gas Cooling Fans.
  2. Reduce Thermal Cycle that would allow Customer to run more cycles per week.
  3. Options to add Heat Exchanger, Variable Speed Control, Front and Rear Shutter Actuators.
