PEX-A Pipes

MODUS PEX-A PIPE SYSTEM

Perfect Crosslinking with ENGEL RAM Technology – Perfect Flexibility

Modus PEX-A pipes are high-performance, superior-quality pipes manufactured exclusively with German ENGEL RAM extrusion technology. This system ensures 85% cross-linking of the polyethylene chains, providing optimal resistance to temperature fluctuations, high pressures, and mechanical stresses. Professional international authorities do not recognize pipes with a cross-linking ratio below 75% as Class A. Modus PEX-A pipes fully comply with DIN EN 4726 and are certified by the SKZ Germany certificate.

Advantages

- Excellent flexibility and shape memory: Even if bent, it returns to its original form with heat.
- High temperature and pressure resistance: Suitable for continuous operating conditions up to 95 °C.
- Smooth inner surface: Provides minimum pressure loss, silent flow and high flow rate.
- Tough and shiny outer surface: ENGEL RAM technology achieves a surface quality that is not possible with infrared systems.
- Thick oxygen barrier: Provides full protection against corrosion and long system life.
- Multi-layer structure: EVOH barrier or barrier-free version options.
- Wide color gamut: Specially produced colors for visual quality and system distinction.
- Sheathed version: Additional mechanical protection in underground and outdoor applications.

Areas of Use

- Underfloor heating and cooling systems
- Radiator connection systems
- Hot and cold water distribution systems
- Industrial installations and central heating applications
- Panel heating / cooling systems

Quality and Certification

All Modus PEX-A pipes undergo continuous laboratory checks throughout the production process. Cross-linking ratio, density, hydrostatic pressure, thermal stability, tensile strength, and oxygen permeability tests are performed regularly. The production system complies with the ISO 9001 quality management standard, the DIN EN ISO 15875 product standard, and SKZ (Germany) certification.

Conclusion

Modus PEX-A piping systems combine flexibility, durability, and aesthetic quality. Manufactured with German ENGEL RAM technology, these pipes offer long-lasting and safe solutions with a zero-complaint philosophy. Thanks to their thick barrier layer, smooth surface, and color saturation, Modus PEX-A truly embodies the slogan "A Flex World."
