howdie kids..
after trying to sell my deisel genset i figured it would be easier to soundproof the bay it is in. I have the area boxed in, aprox 42x36 x 30 inches high, i have a cooling systen i put in to circulate the air so it dosnt get too hot in there...what have some of you used to soundproof your gensets?

You could look at "Roxul" Safe & Sound insulation.

I've had three tries to soundproof a baggage bay for use as a generator bay. All temperatures reported were gotten with a kitchen thermometer taped to the top of the baggage bay.
Try #1: put the generator in.
With the door closed and no openings, there's not enough air circulation to actually cool the generator. It could run for a couple of hours, but would overheat pretty soon. I'd see temperatures of 130 to 150 in the top of the compartment in 10 minutes or so, and they'd remain steady there until the generator overheated.
Noise wise, the noise out the side of the bus was less than the noise going up through the plywood floor of the bus. I was also concerned about the possibility of a burn-through of the plywood in case of fire in the generator compartment.
Attempt #2 was to construct a plywood barrier halfway into the baggage bay, cut a hole and install a ventilation fan into the bulkhead between the condensor compartment and the first baggage bay, and then cut a hole in the floor of the baggage bay aft of the generator.
The sonic barrier material did cut down the noise, and the ventilation cut down on the peak heat, but I wasn't really happy with it yet. still had the burnthrough possibility. I was still seeing high temperatures -- 130 to 150.
Attempt #3 was to remove #2 and reline the compartment with galvanized steel as a fire barrier, covering the soundproofing material, and put a second layer of soundproofing on top of the steal. I used 22 gauge galvanized steel.
I purchased a rigid brand ventilation fan at home depot. It's a 2500 cfm fan in a plastic housing, that runs off 110vac, and i wired a generator-only outlet that i plugged it into. so whenever the generator is running the big fan is runnng, and in times where I wanted a big fan somewhere else I could easily pull it out and use it. (various construction projects, drywall, etc.) This immediately reduced the peak temperature to 80 degrees at the top of the compartment.
This works pretty well, and in case of a generator fire, the steel lining hopefully will direct the flame into the openings in the side of the bus and not into the bus itself, allowing more response time. |
