This FAQ contains frequently asked questions about the CDS extractor tube
that is installed in the VARIBOX FC. This FAQ is divided into four parts: the
characteristics of the CDS extractor tube, the availability, the CDS counter
coupler and the connection of the CDS counter coupler to the CDS extractor
tube.
A CDS extractor tube is a tube in the VARIBOX FC that reaches the lowest
point of the inner container. A counter coupler can be connected to the top of
the CDS extractor tube. The CDS extractor tube is an option on the VARIBOX
FC that allows product to be pumped out of the VARIBOX without opening the
VARIBOX FC. This makes safe working with chemicals possible, and fumes and
product cannot be escape from the VARIBOX FC.
A leak-tight connection is established when connecting the CDS counter
coupler. At the same time, the CDS extractor tube and the CDS counter coupler
are opened. Product can now flow, and air can enter. Fumes and product
cannot escape.
To connect the VARIBOX FC with a CDS extractor tube, a CDS counter coupler
with a hose attached to an installation will be used. Both the CDS extractor
tube and the CDS counter coupler automatically close when disconnecting. By
this way you cannot forget to close the VARIBOX FC and no product can flow
back from the pump installation.
No, the VARIBOX FC with a CDS extractor tube forms a closed system. When
disconnecting, the CDS counter coupler as well as the CDS extractor tube
automatically close. After disconnection there can be still some moist on the
CDS extractor tube and CDS counter coupler, avoid contact with these parts.
No, the CDS extractor tube has an automatic aeration. This is advantageous
because the screwcap remains closed and fumes cannot escape.
Normally it will take approximately 50 minutes to empty a VARIBOX FC with
1000 litres of product with a CDS extractor tube. This depends on the viscosity
of the product and the capacity of the pump installation.
