All performance specifications stated, including but not limited to, pump-down rates and vacuum levels make the following assumptions:
- The Vacuum Chamber is empty.
- The Vacuum Chamber and other system components are clean and dry.
- The System is being operated at Sea Level
- The ambient temperature is 18°C +/- 2°C
- All system components, including those not supplied by Abbess, are appropriate for the system and are functioning properly.
- The specifications are not impacted by the properties of your product.
If you require performance specifications for conditions other than those listed above, it is vital that you make this known to Abbess Instruments in writing. Generally Abbess Instruments recommends choosing chamber and pumping system qualities capable of achieving a theoretical vacuum at least an order of magnitude better than the desired operational vacuum.
It is to be noted that a specification described as '10-5 Torr' is a range, and means the clean, empty, dry chamber system is capable of reaching some undetermined value between 1.0x10-5 and 9.9x10-5 Torr: The (clean, empty, dry) chamber is deemed compliant whether its As-Built base vacuum is 1.0x10-5 Torr or 9.9x10-5 Torr. It does not mean that the chamber is guaranteed to reach every level within that range.

Vacuum Oven Vacuum Storage System
Do you need to dry your products under vacuum? Heat/dry your medical, pharmaceutical, food, sculptures, electronics, and aerospace inventory with Abbess Instruments’ vacuum oven systems. Satisfy Quality Control requirements by automatically monitoring, data-logging, and displaying the storage environment.
As an option, prior to storage, other Abbess systems can take your product, in-situ, all the way from cleansing through to its degassed, dosed, and even thermal-cured, state. Abbess Instruments reduces your production failures and processing time by eliminating moisture issues, air bubbles, and air cavities … and by automation (through controlling your process variables).
Do you require manual or automatic operation? Abbess will work with you to customize the automation to your process, just as we will work with you to ensure the system configuration meets your production needs:
While the most basic system can be controlled manually (by starting/stopping the pump(s) and opening/closing valves), a Vacuum Cycle Controller (VCC) can be added to automate a) vacuum/hold/vent control functions, and b) vacuum and thermal monitoring. Control may be either via panel-mounted buttons and indicators or via a PC with user-specified Graphical User Interface (GUI). Emergency or non-automated vacuum venting can be always readily achieved with the manual vent valves.
The Vacuum Oven System consists of the following: |
V• acuum Chamber - A front loading Aluminum or Stainless Steel Cube (dependent on required operating vacuum) with a Stainless Steel Sheathing System over thermal insulation. Abbess chambers can be designed to reach 10-8 Torr or better. Most oven applications are in the 10-2/10-3 Torr range. |
| Process Control Enclosure – Contains components necessary for
controlling the system as well as logic and interfaces for the Vacuum
Cycle Controller. • Process Timer Control • Temperature Controller • Status Indicators – Provide visual indication of system status. • Vacuum Cycle Controller – Control ON/OFF buttons, main power switch. | |
| Pressure Gauge • Pressure Transducer/ Gauge Controller – Provides pressure display and set point valve control per integral Pressure Transducer data. Also provides pressure set-point relays that can be used for various system control functions. | |
| • Control Valves • Automatic Vent Valve – Automatic solenoid valve vents air or inert gas purge into chamber based on control input from Vacuum Cycle Controller. | |
Do you have limited Counter Space, or Large Batch Sizes? |
The entire system can integrated on a cart using identical or mixed-sized, front-loading cubes in a locker-type configuration. Cart-mounting provides full system mobility and thus flexibility of positioning on your production floor. Mixed-sized inventory? Add optional removable shelving to some, or all, of your cubes for optimal and versatile drying configurability. |
| Do you require any options? Vacuum Oven upgrade options include: | A Vacuum Cycle Controller (VCC) that can be used to automate some or all of the control functions via panel-mounted buttons and indicators (as illustrated here).
