Description
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, supply / isolation amplifier and ATEX vacuum sensor - from one source

All wetted parts of the pumps have excellent chemical resistance and are mainly made of antistatic materials. Included in delivery is a separate gas ballast connection part for use of inert gas.
Performance features
• outstanding chemical resistance and superior vapor tolerance
• flame proof motor with integrated, self-locking overload and excess temperature protection for direct 230V / 50Hz single phase power supply. No need for any additional and specific overcurrent protection device
• overpressure safety relief valves internally and at outlet
• safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage

Description
ATEX chemistry vacuum systems are ready for use for applications with large amounts of condensable vapors due to optimally configured accessories.
