Ten fully configurable programs can also be easily edited and stored. Each program can include up to ten time and pressure steps, with control functions such as venting, pumping and vacuum ramp. External valves and gauge heads connect simply and are recognized automatically via the VACUU·BUSTM control system.

Performance features:

• automatic adjustment of the vacuum level throughout the process for high process reliability and unattended operation (with NT VARIO pumps)
• controls process vacuum, cooling water, and venting to demand
• intuitive operation with turn-and-tap jog wheel and clear text menus, with integrated venting valve
• interactive communication (PC) through RS232C serial interface
• self-configuring by recognizing any VACUU·BUSTM appliance:

NT VARIO pumps, valves, external gauge heads

Applications

Many vacuum processes, such as evaporation or concentration, benefit from automated electronic vacuum control to achieve the most efficient, but also gentle, conditions. The CVC 3000 provides two-point vacuum control by operating

a solenoid valve, as well as providing continuous vacuum control and even fully automatic process control with NT VARIO pumps. In case of valve control, a hysteresis value is suggested automatically. Any parameter can be adjusted, even during vacuum control. Pressure and time settings, as well as run-on time for pump and valves after application is complete, can be adjusted.
