CENTORR VACUUM INDUSTRIES LLC. OFFERS
VACUUM FURNACE UPGRADES FOR
IMPROVED PERFORMANCE AND LESS DOWNTIME!
THESE UPGRADES WILL SAVE YOU TIME AND MONEY!
| WATER SYSTEM:
- The old water system has a paddle flow switch and flow indicator that sticks in the open position, which is a safety issue.
- 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:
- Old design, hot zone graphite felt with graphite yarn sewn to stainless steel body, doors, etc.
- 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:
- Old design, Humphrey air valves on manifold.
- New design, SMC air valve on air manifold for half the cost and less downtime.
| PYROMETER TEMPERATURE SENSING SYSTEM:
- 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.
- 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:
- C/VI offers several sizes, 2Hp, 5Hp, 10Hp, and 25Hp Vacuum Inert Gas Cooling Fans.
- Reduce Thermal Cycle that would allow Customer to run more cycles per week.
- Options to add Heat Exchanger, Variable Speed Control, Front and Rear Shutter Actuators.
