The Model 5400 is the largest thermal vacuum test system in our standard lineup, featuring a 54" diameter chamber.

Vacuum Chamber

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.

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.

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.
The adjustable control panel can be lowered for full access to the vacuum chamber.
