Ostendorf HT Sewer Inspection Chamber D75 (173600-05)

Thanks to the modified composition of raw materials, the HT system provides reliable protection against noise. This hot water resistant system is suitable for all sewer lines according to DIN EN 12056 and DIN 1986-100.
Institute of Construction Physics. Fraunhofer in Stuttgart tested the sound insulation properties of the new HT system according to DIN EN 14366 and obtained a value of 26 dB (A), which corresponds to sound insulation level II. In the experiments, which were close to real conditions, conventional mounting clamps were used. Tests were performed with a fluid flow in the pipeline of 4 l/s.
