Units Varian no longer supports

We repair units their manufacturers no longer support. The Varian U81AG is one of them.

We still take the V-60, V-70, V-80, V-200, V-250, V-300HT, V-450, V-550, V-1800 and U301AG.

What usually goes wrong

  • It will not turn on, or it blows its fuse.
  • The pump will not spin up, or will not come up to speed.
  • A pump connection error.
  • A boot loop, or a dead display or buttons.
  • A dead fan.

Behind most of these sits the power supply, the motor driving circuit, or the control and communication circuits.
