Product Description
TVO-2-VC Vacuum Control Oven with Automation
The TVO-2-VC features an automation feature allows the operator to set a specific vacuum level (Atmosphere to 1 Torr) into the Watlow F4T controller manually or use profiles in the Watlow controller to ramp the vacuum level at a predetermined rate. This feature is helpful when removing moisture from samples that require lower temperature processing. The vacuum setpoint can be set to a level that will maximize the water vapor removal, without freezing the water in the product. As the moisture is removed, the vacuum level can be lowered gradually until the moisture is fully removed. At any point during the process, the oven can be set to go into full vacuum which will fully open the valve between the oven and vacuum pump. This is usually done at or near the end of the process to remove any residual moisture from the product. When the process is complete, the operator/recipe turns off the vacuum event and the oven will automatically backfill to 500 Torr. This backfill limit is controlled by a setpoint in the digital vacuum gauge controller and can be adjusted by the operator if a different level is desired. It can also be set to not auto backfill if desired. The oven can also be programmed to perform this function in a recipe in conjunction with a heating profile allowing multiple pump purge and heating cycles. These cycles help remove moisture from product without the need for the operator to be physically present to manually monitor and control the oven.
Includes upgraded Inficon (1000 Torr to 1mTorr) Full Range Digital Vacuum Gauge to allow for reading the full ultimate vacuum of the process/pump.
