Dosatex - Liquid Dispensing And Total Dyehouse Control

DOSATEX is a single piece of equipment composed of a software core and a
liquid dosing unit, that manages all dyehouse needs, from dyeing recipes to
online supervision and to metering of the distribution of chemicals. The dosing
unit is composed of a product selection and metering block, which are designed
to include the best performing metering technology avaiable on the market,
together with the

maximum ease of maintenance and low footprint. DOSATEX emplyos a Coriolis effect
mass meter and mono pipe distribution system. The meter measures actual mass of
the products being dosed and it is thus completely unaffected by issues of elder
technologies of volume metering such as density variations, thermal expansion
and high speed related inaccuracies.

The exclusive cluster disposition of the product selection valves drammatically
simplifies maintenance while creating the highest possible safety condition even
when incompatible chemicals are used. In fact, safety in a dispensing system is
an absolute must, and the multi-wall design of the product selection block is
the best guarantee for no contamination of fluids.



Principle of operation: the following animation describes the main 8 phases of a
dispensing operation

Open flush valve and set product valve open.

Pump product trough metering head until it reaches delivery valve.

Switch flush and delivery valves position.

Pump product till correct amount is metered.

Close product and open water valve.

Pump water to push all product towards delivery valve.

Close delivery valve and open flush valve to clean out pipe.

Reset all valves to closed waiting for next dispensing.
