  • Programmable closed-loop temperature/pressure control. This system will consist of a Yokogawa UP750 two-loop programmable temperature controller with 300 programs and 3,000 segments. The UP750 will control the temperature and the pressure on the hydraulic ram on the same timeline.
  • Mechanical vacuum pump.
  • High vacuum operation. Includes 6” high-speed diffusion pump, high-vacuum gate valve, foreline valve, and all necessary vacuum plumbing and automation to enable the system to operate in high vacuum.
  • Liquid nitrogen cold trap with digital temperature controller to minimize liquid nitrogen consumption.
  • Digital ram movement indicator with resolution to the nearest .001”.
  • Digital vacuum gauge with a range of atmosphere to 1 x 10(-5) Torr.
  • Digital high-limit safety controller with Type “C” thermocouple.
  • We provide written operating procedures, complete detailed electrical schematics, and manuals for all instrumentation and controls on the hot press.
  • Includes one day of test fire and operator training at our plant in Terryville, Connecticut, USA.


  • 2200o C operation (3992o F). Includes automatic thermocouple retractor and optical pyrometer.
  • Roots blower.
  • Remote diagnostics via a modem, enabling us to remotely aid in troubleshooting the hot press and guide your maintenance people directly. This should virtually eliminate the need for field service.
  • 6-channel Yokogawa paperless datalogging chart recorder with digital communications. Network compatible – can appear as a node on a network, making remote data gathering fast and easy. Includes built-in memory card for storage.
  • Yokogawa Light Loader to facilitate uploading and downloading programs, configuration files, and auto-tuning parameters. This device clips on the face of the Yokogawa UP750 instrument and plugs into a USB port on a PC-based laptop or desktop computer, greatly facilitating and simplifying instrument configuration, program storage, and auto-tuning. Can be used for writing programs and storing detailed configuration data.
