Silencer 7

Sound suppression for cooling containers

Silencer7 makes it possible to reduce noise nuisance from refrigerated containers by up to 60% and is therefore ideal for containers located in denser built-up areas and areas with noise limits.

About Silencer 7

Silencer 7 was developed and designed in close collaboration between Aarhus Container Depot and Bardraam Air Technology, with the aim of reducing noise nuisances from refrigerated containers.

Bardram has its roots all the way back in 1952 and especially the firm’s essentials solutions have got the Danish food industry’s positive attention over the years.

Silencer 7 is therefore ideal for containers that must comply with noise limits, for example containers placed in densely built-up areas.
Silencer7 has got its name from the 7 dB sound attenuation that is possible with this unique product.

Silencer7 has been developed in Denmark, partly based on more than 25 years of experience with containers on all levels, and more than 30 years of experience with external sound insulation in connection with ventilation systems.
