ACOUSTIC ENCLOSURE FOR A “MAXA HWA1A 0260” CHILLER

lanning principles
The planning of our sound hood is based on the following principles:

1. The smallest possible size of the sound hood
2. Modular expandability
3. Highest possible sound insulation
4. Avoidance of system performance losses
5. Unhindered access for service and maintenance
6. Relocation of the air inlet to the shady side of the system
lower delta T)

Outlet refrigeration system
The system has a maximum cooling capacity of 59.7 kW and uses an axial fan to move an air volume of 19,584 m3/h at maximum capacity.

The system has 2 scroll compressors with 1 refrigeration circuit. R410A is used as refrigerant.

System sound pressure level
The sound pressure level at a distance of 10 meters from the system is 50.3 dB(A) according to ISO3744:210, with a sound power level of 81 dB according to UIN EN ISO 9614.

Sound hood concept
Aluminum frame construction to accommodate soundproof aluminum service doors for air outlet and air inlet and integration around the system.

The acoustic hood is designed for an air volume of 20,100 m3/h, the system can be operated in the acoustic hood without pressure loss.

The basic construction has the following dimensions: 1'700 x 1'700 x 2'635 mm (L x W x H)

Service doors with internal 40 mm thick sound insulation are integrated around the systems.

These service doors are equipped with quick-release fasteners that can be easily removed by one person. In this way we ensure unhindered access for service and maintenance work.
The insulation material offers high sound insulation over the entire frequency spectrum.

The insulation is also water and UV resistant and does not build up bacteria and fungi.

The insulation also corresponds to the highest fire safety class.

Advantages of the sound hood
All-round high sound reduction between 18 and 20 dB(A).

Protection of the systems against weather influences (direct sunlight, rain, hail, wind.

Unrestricted access to the facilities for service and maintenance work.

Material
All components of the acoustic hood are recyclable
