With its wide range of formats, the eSILENT PRISMA is suitable for various devices such as heat pumps, air conditioning and refrigeration systems, and pool heat pumps. It reduces their noise by 12–20 dB(A), enabling compliance with the relevant guidelines even in limited installation spaces. At the same time, it protects against weather, vandalism, and theft, and is eligible for funding under the BEG.
With its modern look, the designer soundproofing hood blends attractively into the garden or cityscape. Attenuation levels of 12/14/18/20 dB(A) are available as standard. Specific airflow variants are available here, which are suitable for different systems and installation situations: The 12/14/18 models are available as HV with rear air intake and SV with side air intake. For units with side air intake and vertical air outlet, the PRISMA Type 20SO sound insulation hood is available in various sizes. This reduces noise by up to 20 dB(A) and at the same time directs the air outlet upwards. The PRISMA 12 reduces noise through 200 mm thick sound grilles with 50 mm sound insulation material in the walls, while the PRISMA 14 has 300 mm thick sound grilles. Finally, the PRISMA 18 is equipped with 300 mm thick sound grilles and 100 mm insulation material in the walls.
