Using of an extra silent-working cooling technic is recommended. The extra silent designed construction are configured in a closed, sound-proof, weather-compatible box with extra vibration protection.
Several times we experienced, that the owners of coldrooms changes air condensing units to extra silent working because they got complain from habitat by reason of loud gear. After the construction of extra silent design the competent authority and the habitat can calm down as well.
The difference in prices is significant compared to the original air condensing units, so before the construction it is recommended to think over what possibilities do we have to build in an original air condensing unit. So we suggest the extra silent design just as a final solution considering its overhead cost.
