Your advantages

1. INDEPENDENCE FROM EXTERNAL EXPERTS

We instruct and train your technical staff to complete the entire installation themselves without any external support.

3. ONE-STOP SHOP

EPI has all you need in one place for your convenience, ranging from sensor paths to "bits" at the data centre.

 

2. PHS CAN BE CUSTOMISED ON SITE

Our system is able to cope with deviations from the installation scheme and adapts to any specific situation.

4. FLEXIBLY USED AND MAINTENANCE-FREE

PHS may be used in a variety of applications (roofs, walls, floorings) and, once installed, is 100% maintenance-free.

Application areas

Flat roof

For all types of flat roofs (warm roofs, cold roofs, green roofs):

Depending on where the PHS is installed within the roofing system, it generates specific data relating to the tightness of the roof sealant, to the water saturation limits of the insulation system, or to the diffusion resistance of the vapour barrier.

Wooden structures

Pre-fabricated solid hardwood or timber-framed houses:

The PHS detects and signalises water leaks and humidity on roofs, walls, floor heating systems etc. and also identifies condensation.

Wet rooms

In wet rooms, such as bathrooms, it is essential to identify leaky drains, supply lines etc. immediately.

Windows and doors

Indoor condensation on windows and doors resulting from thermal bridges can be detected easily.

Tested quality

"EPI GmbH turned to OFI to have the durability of their roof sensor system tested. As an accredited testing agency, we performed environmental simulation tests to check sensor functionality, conducted a chemical analysis to evaluate the migration potential of flat roof component chemicals and assessed the corrosion resistance of the connector contacts. In conclusion, the tests performed by OFI have verified the functionality of the roof sensor and its applicability on a variety of insulation materials."

"The printed EPI sensors were tested by Holzforschung Austria in climatic chambers to verify the validity of their humidity measurement. The sensors were exposed to different temperature and humidity extremes. Relative humidity readings of the PHS were found to correlate well with those of reference sensors of Holzforschung Austria."

DI Dr. Julia Bachinger, expert of Holzforschung Austria - Österreichische Gesellschaft für Holzforschung (HFA-ÖGH), www.holzforschung.at
 


"A number of mould-resistant substrates were preselected and subjected to various tests (e.g. Hemmhof test according to EN 1104). Additionally, aging/weathering tests (to evaluate service life classes), print tests and climate chamber measurements (to check sensor functionality) were conducted to select the appropriate printing substrate. The PHS is resistant to moulding, weathering and aging, pressure and shear loads, and can be used in any climate.“
