Is InTex suited for all applications?
InTex is best suited for laboratories, offices, industry, and the
food industry. The product does not apply to aggressive
environments (below pH4) such as dairies, equalising rooms (batch

textile ducts are washed. The sensor MUST be removed before
washing. Battery type is 1.5V AAA alkaline.

the master via a radio signal (868 MHz).

Yes, the requirements are as follows:
Ethernet 10 or 100 Mbit/s

What does "lifetime warranty" of my TBV system
Provided that an InTex service agreement is entered into
within 12 months from date of delivery KE Fibertec offers a
"lifetime warranty" of 15 years on your TBV system. This extended
warranty only applies in connection with a service agreement with
an authorized KE partner for the entire warranty period.
The highlight of this warranty is that it does not only cover the
textile material but the entire product, i.e. components such as
zippers, nozzles, suspension, etc.
Further, our documentation requirement regarding maintenance
intervals and documentation for proper cleaning will not be
necessary - a requirement that is almost impossible for a customer
to meet in practise. A TBV system with InTex
allows all data from initial start to be downloaded anytime and
