Many important research and industrial processes require vacuum in what is referred to as the “fine vacuum” range, which is between 0.1 and 0.001 Torr. Historically, process control at these vacuum levels has been problematic. Turning a pump on and off or using “false air” (a managed leak) to achieve approximate vacuum levels provides coarse control at best.
“Programmable vacuum control for critical processes.”
Fine vacuum control is available in two sizes: one with KF DN 16 tubing and flanges and another with KF DN 25 tubing and flanges to support larger pumps. The fine vacuum control packages can be used with any pump capable of fine vacuum depths, including VACUUBRAND’s rotary vane and ultra-low-maintenance Chemistry-HYBRID pumps.
VACUUBRAND’s fine vacuum control package can provide programmable control for critical vacuum processes, like molecular distillation for the purification of oils. A patented chemical- and shock-resistant vacuum sensor sends signals to a digital controller that operates a chemical-resistant solenoid valve. The controller can produce vacuum steps and ramps, and store up to 10 processes.
