The soundproof drainage pipe system
PHONEX AS PLUS: Living comfort without disturbing noise
In wide frequency ranges, a conventional drainage system can be excited by resonances to natural vibrations and thereby becomes a sound amplifier. The KE KELIT solution for this problem is very simple: the noise insulating system PHONEX. The homogeneous one-layer technology prevents sound from being transmitted and transforms it into heat.
Sound-insulating drainage system: The unique material composition for improved noise behavior ensures a first-class reduction of unwanted noise from the drainage system inside the building. The high material density guarantees optimum sound insulation. PHONEX AS-PLUS is durable, corrosion-resistant and the material mixture has a high chemical resistance to loads in waste water.
Field of application: | For waste water in the house sewer |
Sound insulation: | Sound insulation measurements behind an installation wall of 220 kg/m2 and a water flow rate of 2 l/sec with the dimension DN 100 resulted in a value of < 10 db(A) |
Tests: | according to ÖNORM EN 1451 Dimensions: according to ÖNORM EN 12056 Fire behavior: ÖNORM EN 13501 Determination of the sound level in accordance with DIN 52219 |
Dimension range: | DN 50; 70; 90; 100; 125; 150 |
Colour: | Light gray RAL7035 |
Special parts: | Standard push-on sleeve This is equipped with structure-borne sound decoupling and an integrated expansion compensator. |
The PHONEX AS PLUS pipe uses an innovative push-fit socket connection with a patented seal that requires no lubricant. This technology enables simple, quick and tight installation.
PHONEX ST: three-layer technology
PHONEX ST pipes are co-extruded from polypropylene using innovative three-layer technology. The outer layer is particularly impact-resistant and protects against damage. The middle layer reliably insulates sound. This means that PHONEX ST can be used safely in buildings with sound insulation requirements based on DIN 4109. The smooth inner layer protects against corrosion caused by aggressive household chemicals. As the impact and deflection noise of waste water is greatest in bends and branches, PHONEX ST fittings are made entirely of sound-insulating material.
Sound insulation
In tests at the Fraunhofer Institute for Building Physics in Stuttgart, PHONEX ST has demonstrated its good sound insulation properties in a practical installation situation. PHONEX ST complies with all applicable regulations for drainage systems, including noise reduction and fire behavior (DIN 4102). The noise level emitted by the system was determined by the Fraunhofer Institute for Building Physics in Stuttgart (based on DIN 4109). The drainage pipe system proved its excellent properties here. A very good 21 dB(A) at 2 l/s was achieved with our system clamp for the UG rear room requiring protection (P-BA 62/2019).
The innovative three-layer technology of the drainage system:
- The outer layer is particularly impact-resistant and protects against damage
- The middle layer reliably insulates sound
- The smooth inner layer protects against corrosion caused by aggressive household chemicals
The high material density guarantees optimum sound insulation. PHONEX ST is durable, corrosion-resistant and the material mixture has a high chemical resistance to pollution in waste water.
