I have three partly finished sheet metal sheds in between my garages that use to be for storage of fire wood, this year i'm switching my heating system and i have two empty sheds to configure and make them more useful. I need some advice for insulation and ventilation, now if i leave any rubber parts in they turn to dust because of the heat, also one,( the smallest) shed needs to house an decent size air compressor, and a small to medium sized gasoline generator. I'll run underground air lines and power cables to connect the sheds to both garages to have compressed air from one compressor and emergency power to both houses .
 
the generator is easy, pipe the a/cleaner and exhaust outside.

don't know anything about northern shed needs tho
 
Both the compressor and the generator are going to need a well ventilated space. They both breath air and are air cooled, yes?.

The compressor wants to be kept cool to allow the moisture in the hot compressed air to condense and precipitate.

If it freezes where you are, you'll want to insulate to protect the equipment from the low temps.

If the interior reaches 100°F or more in hot weather I would suggest a fan to draw exterior air in plus an adequate vent in the roof to let the hottest air out.

i thought you kept the lines cool. i run mine in a zig zag fashion, on the wall (like a 1" pipe radiator), after the compressor, with a drum drip before it enters the building. i have very little moisture inside. i'm in a humid area.

what up with the fan, is it totally enclosed?

I almost overlooked that they are air cooled, the shed will be completely enclosed to keep the weather out, here summer temperatures can reach 40 degrees centigrade and winters as low as -20 centigrade. So i'll be definitely looking for some vents and fan or two, i'm also concerned about the noise i'm in a suburban neighborhood very tightly populated, and having an sheet metal shed acting like a megaphone is a big worry.
 
wire it so the fan comes on when the equipment is turned on

Please describe the compressor and the generator so we know if we're talking about Chihuahuas or Wolves.

The 40C isn't a big problem but, the -20C is a killer if you don't prepare properly.
Do you have access to rigid foam insulation panels (RFIP) in your part of the world?

Rigid Foam Insulation Panel Examples

Covering the interior with panels will greatly attenuate the noise also.
The biggest noisemaker on a reciprocating compressor is usually the air intake. You might try plumbing the intake filter into an insulated box, inside the shed, but vented to the exterior with insulated flexible duct.

I suspect that the thickness of RFIP youl'd need to protect from -20C (do your research) will be impractical.
A low wattage heater replacing the oil drain plug in the compressor can keep the pump safe.
 
The compressor is been modified so many times over the years that is considered DIY by now it uses truck air pump three phase motor and i have three 60 liter propane high pressure cylinders that i plan adding to the system for extra capacity, as for the generator for now i have small 2kw bosch unit, but i plan getting an 10-20kw diesel generator. We have rigid foam insulation panels (RFIP) here, which is the obvious choice but the sheet metal in corrugated which will leave me gaps, other thing i'm thinking about is maybe digging down in the ground, i need to concrete the floor eventually i may increase the ceiling height and being underground even slightly should help in the winters.
 
Digging down won't help unless you protect the space from the ambient temperature. That's what the shed is for, no?
180 Liters is about 48 Gallons. You'll need to orient and plumb the propane cylinders so that the water condensate can be drained.

spray foam, there are different size disposable kits so you can diy
