With the new ATEX VARIO® chemistry diaphragm pumps and vacuum systems, the vacuum can be precisely controlled by the motor speed. The VARIO® pump is driven by an additional control signal line. The optional vacuum controller CVC 3000 with system accessories (I/O-Module, supply / isolation amplifier) and ATEX vacuum sensor enable fully automatic evaporations without the need for parameter settings or user programming. With the adaptive control it finds the boiling pressure independently and adjusts the vacuum continuously and optimally according to the vapor pressure.
The vacuum controller and system accessories are installed in a non-hazardous area.

Performance features
• full advantage of ATEX chemistry diaphragm pumps with separator AK and emission condenser EK
• VARIO®: short process times due to hysteresis-free VARIO® vacuum control
• VARIO®: VARIO® pump operates on demand only as fast as necessary – minimal power consumption, extended maintenance intervals, silent operation
• VARIO®: vacuum controller CVC 3000 (optional) for precise vacuum control and fully automatic processes
• complete system accessories I/O module, isolation amplifier and ATEX vacuum sensor - from one source

ATEX chemistry vacuum systems are ready for use for applications with large amounts of condensable vapors due to optimally configured accessories. Typical applications are rotary evaporators and drying ovens with potentially explosive atmospheres. The separator at the inlet (AK) retains particles and liquid droplets. The waste vapor condenser at the outlet (EK) is highly efficient and compact. The condenser enables near-100-percent solvent recovery. Included in delivery is a separate gas ballast connection part for use with inert gas.

The PC 3001 VARIO select pumping unit precisely controls the vacuum level in order to achieve unparalleled process control. This pump is suitable for even high boiling point solvents.

The integrated VACUU•SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. The VACUU•SELECT controller has you covered. Use manual set-point-control for simple processes, run fully automated distillations, or create your own application with simple drag-and-drop editing. For solvent evaporation, the VACUU•SELECT controller detects solvent boiling and automatically adjusts the pump's motor speed to maintain process control.

The VARIO motor speed control also makes the pump whisper quiet and provides for exceptionally long maintenance intervals.

The inlet separator, made of glass with a robust protective coating, prevents particles and liquid droplets from entering the pump, preventing damage and extending pump life. And the exhaust vapor condenser allows for nearly complete recovery of solvents when used with a chilled water line or recirculating chiller for economical recycling and environmental protection.

Performance features
• simplify lab work with the VACUU•SELECT vacuum controller with graphic user interface and predefined applications
• automatic boiling point detection and continuous optimization of vacuum levels for quick process times
• compact and powerful; superior performance even with continuous condensate purge
• whisper quiet and ultra low vibration
• eco-friendly: extremely low power consumption and efficient solvent recover
