Topas GmbH dilution systems have been designed for defined total flow rates and fixed dilution factors and have been developed for on-site filter testing. The dynamic dilution systems DDS and HDS can be used for different total volume flows, with the dilution factor being adjusted by the user.
Dilution is performed by all of these devices without any auxiliary pressurized air. The dilution factor is continuously monitored by an internal sensor unit and is automatically readjusted in the system HDS 561. All types of dilution instruments are designed for mobile use. The DIL554 can be operated from an internal battery.
