Model 2000

DVI Model 2000 - Front View

The Model 2000 combines an accessible work space and a 5 cubic foot, 20" diameter chamber in a bench top model that has all the features of our larger systems. The magnetically levitated turbomolecular pump is capable of evacuating the chamber from complete shutdown (atmosphere) to high vacuum in 10 minutes, saving valuable lab time.

Vacuum Chamber

Inner Diameter 20" (50.8 cm)
Depth 22" (55.88 cm)
Shape cylinder
Orientation horizontal
Material Stainless Steel 304

Access Ports

Number of Ports 4 (2 on each side)
Inner Diameter 6" (15.24 cm)
Type ASA/ANSI flanges
Material Stainless Steel 304
  • Each access port is fitted with an o-ring grooved ASA/ANSI flange, enhanced for safety and convenience with tapped bolt holes.
  • Flanges are covered with a fixed, flat (smooth-faced) blank, sealed with a Viton o-ring, and compressed with stainless steel, hex-head bolts, nuts and washers.
  • Other flange configurations are available, including view ports.

Thermal Platen

Width 17" (43.18 cm)
Length 20" (50.8 cm)
Material Aluminum, anodized black
  • The thermal platen is embedded with electric heating elements and copper passages for LN2 cooling, providing a temperature range of -150°C to 200°C.


  • Edwards magnetically levitated turbopump capable of pumping N2 at 450 l/s.
  • Adixen / Alcatel 2021 rotary vane roughing / backing pump.


  • A microprocessor-based PLC provides push-button selection of pumpdown and venting cycles, while providing preset pressure interlocks.
    • Manual mode allows control of the pumps and valves for troubleshooting or non-standard operation.
    • Automatic mode allows unattended pumpdown from atmosphere to high vacuum and initiation of thermal test cycle (if enabled).
    • Automatic cycles are designed with time, pressure, and temperature interlocks affording maximum protection to the hardware under test as well as the components of the system.
  • The thermal test cycle is controlled by a Eurotherm model 2404 temperature controller/programmer with digital temperature display.
    • The programmer maintains constant PID control of the temperature and has the capability of setting time and temperature through a 4 or 20 program, 16 segment ramp and soak capability.
    • 4 programs come standard with an option for 20.
  • The operator interface includes an 8.4" color touch screen for easy on-screen control and display of vacuum system status.
