VARIO® chemistry vacuum system in action

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 VACUU·SELECT with ATEX vacuum sensor and Connection Box 100 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 the Connection Box 100 are installed in a non-hazardous area.
