FAQ

Why should I use InTex?

To maintain a healthy indoor climate and obtain an energy-efficient ventilation system. 

What are the temperature requirements in the room?
0-40°C.

What are the humidity requirements in the room?
0-90% RH.

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 chilling), and in slaughterhouses. However, InTex is very well suited for swimming pool areas as it will remain dry when installed in the duct.

Where in the building is the best place for the Master unit
Preferably centrally in the building, e.g. in a plant room, the works manager's office etc. By placing it as visible as possible you can see on the indicator if there is a connection to the server. In this case you will have a green light.

How long is the battery life?
One battery is capable of approx. 50,000 loggings at 20°C. The number of loggings depends on how often the sensor sends information on pressure and temperature back to the master. We recommend battery replacement every time the textile ducts are washed. The sensor MUST be removed before washing. Battery type is 1.5V AAA alkaline.

How does the sensor communicate with the master?
The sensor contains a radio device which connects to the master via a radio signal (868 MHz). 

How much power does a master use?
The master uses less than 3 Watts. 

Does InTex require network access?
Yes, the requirements are as follows:
Ethernet 10 or 100 Mbit/s
DHCP server for distribution of IP addresses
Data transmission on port 12883 (TCP).
In most cases the master will work as a plug & play device without any network alterations necessary.

What is the maximum distance between the sensor and the master?
Max. 30 metres in heavyweight buildings and 75 metres in lightweight buildings.

What does a blinking red light on the master mean?
There is no connection to the InTex web service.

How many sensors can each master cover?
Maximum 10

How is the InTex sensor installed?
See mounting instruction

Do we need InTex sensors on all our ducts?
Not if they are all the same type or similar. Then you only need to install one sensor that will represent similar ducts.

Should I use a soft starter?
Yes once the Intex solution has been installed, a soft starter is required for start-up of the ventilation system in order to avoid stress on the product.

How do I get access to intex.ke-fibertec.com?
Contact KE Fibertec's sales department for further information.

How soon can I have the InTex device?
Same terms of delivery apply for all our products. The InTex sensor and master are stock items.


What does "lifetime warranty" of my TBV system mean?

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 anywhere.

Is there any minimum duct dimensions with InTex?
Yes Ø-150, D-300/150 and Q-180/180 (if symmetric)

Is InTex suitable for retrofitting to existing textile ducts?
Yes. Please, contact KE Fibertec's sales department for further information.
