Key High ACP-4000Key High Vacuum Products recently released its ACP-4000 automatic valve controller to provide safe and reliable automation for cryo-pumped vacuum systems. The company says that these controllers additionally grant:

  • The power to automatically control and monitor all valves and pumps associated with a typical cryo-pumped vacuum system.
  • The capacity to monitor all key functions in the system, such as cryo-pump temperature, vacuum pressure, valve status, and if a fault is found, the ability to safely make the vacuum system go into a standby mode.
  • Pre-programmed standard operating modes, which include automatic, protected manual, venting and password-protected, non-protected manual, to ensure reliable and safe cryo-pumping system operation.
  • Startup, regeneration, pump down and venting as simple as pressing a button.
  • An affordable price — less than 25 percent of the cost of setting up a computer-controlled cryo-pumped vacuum system.
  • An easy-to-read, well-lit display, in addition to dual thermocouple gauges and a cryo-pump temperature indicator.
  • A stand-alone unit designed for use with most cryo-pumped vacuum systems. 
  • No need to write any software.
  • A variety of output voltages.
