Hi guys,
When I was on the road I`d often be parked up next to a fridge truck with the unit banging away for all it was worth. Now here`s my question: just why are they so noisy, I`ve worked on large diesel compressors that you can hardly hear running. I imagine the engines for the fridge units aren`t overly large but you can hear them across a large factory yard in fact they seem noisier than the truck itself. Is it all down to cost ie the makers don`t want to put a quiet exhaust and decent sound antenuation in them? after all noise pollution is a big problem these days.
