CLIMLINER Slab CLEANTEC
The CLIMLINER Slab CLEANTEC system will therefore be able to reduce silencers’ size, and it is specially indicated for cases where the duct is placed close to a wall or where its length should be limited.
CLIMLINER Slab CLEANTEC system can also be used inside ventilation units or for plenum boxes.
CLIMLINER Slab CLEANTEC system is composed of CLEANTEC Slabs: glass wool slabs faced with tight and high quality glass fabric. This fabric will be installed in contact with the airstream, providing:
- High acoustic absorption: The inside facing ensures a high acoustic absorption
- The inside facing constitutes a smooth surface, with high resistance to tearing (cleanable by brushing)
CLIMLINER Slab CLEANTEC profiles, to be installed on the internal joints of the metal duct to provide a mechanical fixation of the insulation to the duct (see installation details, available on demand).

Fire protection
CLIMLINER Slab CLEANTEC provides the best fire classification for insulation of metal ducts : Euroclass A2-s1,d0
This classification means :
-
Fire safety
-
No opaque smoke emission
-
No flamming droplets / particles burning
-
Minimum firegrowth rate
-
Minimum total heat released
Acoustic insulation
The glass fabric, combined with the glass wool, provides optimum levels for noise reduction through the duct. High acoustic absorption by the glass wool allows noise reduction of the noise generated in the air fan; but also noise reduction due to the air movement inside the duct.
The alfa Sabine coefficient α of the CLEANTEC slabs allow calculation of the sound attenuation inside a duct: Sabine equation provides an approximation of the linear noise reduction inside the duct:
-
Reduction in dB/m = 1,05 α × 1,4 (P/S)
Being P the perimeter of the inside duct cross section 2 (a+b) and S the section of airflow inside the duct (a x b)

The linear noise reduction in a duct by CLIMLINER Slab CLEANTEC system have been evaluated in CAP HORN solutions Lab as a comparison with the Sabine algorithm to on-site real measures. The results are available in the document « Rapport d’essai sur le SYSTEME CLEANTEC » on demand.
