The Alfaidro NOFIRE system includes a FASER pipe made of PP-RCT with flame-retardant additive and reinforced by an intermediate layer of special fibers, and PP-RCT fittings; it meets high standards of mechanical and aging resistance and it is classified to fire reaction – in accordance to the UNI EN 13501-1 – as B-s1-d0.

Its use is approved in environments where the fire risk class is:

– Low Hazard (LH) or Ordinary Hazard (OH) as defined by UNI EN 12845

– Light Hazard (LH) according to NFPA 13, 13R and 13D standards

– HC-1 according to the FM 1635 standard.

It can be installed both in new and pre-existing systems and, by using the weld saddles, it is possible to realize end-center and end-side arrays typical of sprinkler systems in a simple and fast way.

The Alfaidro NOFIRE range has passed rigorous fire resistance tests carried out by national and international laboratories and it is classified:

– Class B, s1, d0 according to EN 13501-1 (equivalent to a class 1 according to DM 15/03/2005);

– Class B1 according to DIN 4102-1.

In addition, it is approved for the fire-fighting systems:


According to the UNI EN 12845 (design, installation and maintenance reference regulation for the fire sprinkler systems) “An automatic sprinkler system is designed to detect a fire and extinguish it with water in its early stages or hold the fire in check so that extinguishment can be completed by other means”.

The sprinklers to use with the ALFAIDRO NOFIRE system are the ones with red glass bulb and they have to be certified: normal activation is at 155 °F (rapid response). When the hot smoke flow reaches the sprinkler head and the activation temperature, it opens and starts sprinkling water to the underneath area.

The ALFAIDRO NOFIRE system guarantees the water supply to the sprinkler at the pressure and flow conditions required by the plant and for the minimum duration prescribed by the reference standards, according to UNI EN 12845:

– 30 minutes for LH activities

– 60 minutes for OH activity

Alfaidro NOFIRE pipes are manufactured with the innovative composite FASER technology: the internal and external layers are made of PP-RCT, a 3rd-generation polymer that provides high mechanical and aging resistance; the intermediate layer in PPFV provides dimensional stability, which allows the use of a reduced number of clamping elements during the installation.
