The results were referenced to a high-quality brush system of a well-known manufacturer. The tests for air permeability included different setups with both Hanno® Clima-Tect® and den brush system
1. Without cable penetration (zero measurements)
2. With cable strand: hanging, horizontal and after moving the cable strand
In addition, the acoustic load was determined at a differential pressure of 30 Pa.
On average, 2.8 times higher efficiency of air flow reduction in comparison with the brush system
The results were very clear: For example, the test setup that simulated practical conditions most closely obtained a 2.7 times higher efficiency of Hanno® Clima-Tect® than the brush system at 30 PA. In this setup, the cable strands were moved slightly after installation in order to simulate the subsequent cable laying and/or the alignment of objects.
All other test layouts also confirmed the distinctly higher efficiency of Hanno® Clima-Tect®, which was better between factor 2.4 and 4 for all setups. The air flow was reduced by factor 2.8 on average. The TÜV writes
: „…From this, it can be concluded that the sealing element Clima-Tect® has a substantially better sealing performance than the reference object …“
Hanno® Clima-Tect® improves sound intensity reduction by approximately 75% compared with brush system
During the additional airborne sound measurements the sound pressure level was reduced by 19.1 dB. „…This corresponds to a reduction of the perceived volume by about 75%. …“, TÜV NORD says. This shows that Hanno® Clima-Tect® not only saves a substantial amount of energy because it reduces the amount of air lost, it can also distinctly attenuate the noise level in server rooms.
The final assessment of TÜV reads: “The results of the tests have shown that the sealing action obtained with the sealing element Hanno® Clima-Tect® is higher than that of the reference product …. It was also found that the interference due to airborne noise is lower in case of the sealing element Hanno® Clima-Tect® than with the reference object.“
