RAUTITAN Water Services System
Description

The RAUTITAN water services system was developed in collaboration with industry professionals to meet the needs of designer, developer, builder and installer.  Based on the advanced compression sleeve jointing technology the RAUTITAN system provides a robust, reliable and simple connection and the highest standards in hygiene, comfort and lifecycle costs.  

The strength and flexibility of cross-linked high-density polyethylene (PE-Xa) pipes used together with a complete range of RAUTITAN MX (DZR Brass) and RAUTITAN PX (polymer PPSU) fittings makes RAUTITAN a superior system for both residential and commercial applications.

Key Features
  • 100% leak-proof joint
  • Up to 60% faster installation than traditional copper systems
  • Reduction in workmanship fault
  • No welding hot work or electricity required
  • No scaling
  • Heat resistant up to 100°C
  • Corrosion resistant
  • Service life > 50 years
  • Up to 30% less hydraulic losses
  • Burst pressure up to 70bar.

Rehau's comprehensive range of pipe and fittings from sizes 16-63mm across all applications covers hot and cold drinking water (with a specifically red-coloured pipe for hot drinking water application) as well as pipes for rainwater and recycled water.

Other Performance Attributes

RAUTITAN PX FITTINGS

Made from robust, lightweight polymer (PPSU) the PX fitting weighs approximately 80% less than similar brass fittings.  The new easy-slide PX compression sleeve joint can be completed up to 20% faster with 30% less effort.  Tough and durable, PX fittings do not display the same corrosion effects as can be seen in metal fittings, do not tend to scale and are hygienically non- hazardous – the ideal fitting for drinking water installations with the additional peace of mind against scrap-value theft.
