CCM - Concentration Control Module

In filter testing a well defined and constant dust concentration in the dirty gas upstream of the filter sample is essential

Our NEW

CCM - Concentration Control Module

In connection with our laser-photometer the new device is made to compensate for the changes in volumetric feeding and/or 
for deposition of dust crusts within the screw and stabilize the dust concentration on the dirty-gas side of the filter test rig

Supply and Control Units with Data Acquisition

Supply and Control Units with Data Acquisition

The use of our Supply and Control Units (SCUs) are not limited to our filter tester but can be applied to operate a large variety of installation, e.g. laboratory test rigs of all kind, industrial installations, etc. 

Our software MeLab is a multifunctional tool which allows to operate these installation and also provides complete Data Acquisition and storage.

MeLab is operated with out specific knowledge of programming but by using Protocols and Scripts which require very simple commands only.

Absolute Filter ISO 5011

• multiple use of the analytical filter
• immense time saving compared to the widely used round flat filters
• no dismounting of test installation for weighing

Fast Pressure Measurements

Fast operating differential pressure transducers

• for the measurement of pressure pulses in filter elements (e. g. bags, candles) during cleaning or
• to analyse the cleaning system including pressure tank and air ducts
