Rail-mounted vacuum regulator VACUU·SELECT

Overview

• Complete, ready-to-use vacuum controller for scaffold mounting with integrated solenoid isolation valve and standard hose connections
• Predefined vacuum applications and automatic boiling point detection for solvent evaporation
• Inline installation between pump and vacuum application; integrated venting valve supports inert gas connection
• Integrated check valve minimizes interaction with other applications on the same vacuum supply
• Ceramic diaphragm sensor with two-point control maintains stable process pressure

Product details
The VACUU·SELECT complete controller increases process efficiency for applications served by a vacuum source such as a standalone pump or a vacuum network. Operate with manual set-point control for straightforward tasks, run predefined applications at the touch of a button, or create and edit custom applications via drag-and-drop. The unit is available as a benchtop model, a scaffold-mounted version or an inset version for lab casework. The integrated compact assembly includes the VACUU·SELECT vacuum controller, a chemical-resistant solenoid isolation valve, an integrated check (non-return) valve and a ceramic diaphragm vacuum sensor with venting valve. Compact and easy to install, VACUU·SELECT provides an intuitive, application-based user interface. For solvent evaporation it detects boiling pressure and holds the pressure stable using two-point control.
