Performance Specifications

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.

Standard Features

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.
• Vacuum Pump- Provided with Inlet and Exhaust filters. Power and automatic control integrated in the VCC controller
• Thermal System –  Thermal pad heating elements mounted to each chamber surface controlled by a PID temperature Controller mounted in the Process Control Enclosure. This enables heating to 200C.  Extensive power demand of the thermal system necessitates sequencing the thermal process after pump down to set point pressure levels is complete.

 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).
A VCC controlled by a PC with a user-specified Graphical User Interface (GUI) operated through a touch-screen (as illustrated in the Vacuum Storage System).
Heavy-duty mobile cart.
FDA-approved internal coating.
Shelving (passive).
Thermal plates/shelving (for heating up to 150C, or 300C).
Inert gas purge.
Circulation fans.

 

Are you concerned about craftsmanship?

• Surfaces protected by Teflon coating for easy cleaning
• A full diameter clear window for viewing
• Heating systems consisting of an electric heater and temperature controller
• Brackets to support trays or racks
• Vacuum Sequencer and Cycle Timer with Vacuum Regulator
• Lights
• Electronic feed-thru
• Mixers

All chambers are vacuum tested to 29.92 inches of Hg or optional up to 10-8 ccHe/sec and should maintain this for its life dependent on seal condition and customer use.
