I will be replacing my old generator at my house. It is all of 6yrs old and the sheet metal housing is rusting. I have the old one sold and will replace it with with a a 20 kw unit. Now here is the reason for the post the new unit has an aluminum housing but the the frame that the engine sits on is steel, and the housing sits on the frame. how does one insulate the frame from the housing so as not to start the rusting process again.I'm a 100ft from the canal and 1600ft from the ocean,lots of salt in the air...thanks for any help..Russ

Rubber vibration dampeners?

Remove all the fasteners on the enclosure and coat them with TefGel before reinstalling them. I did that to the fasteners on the steel enclosure of my 21 KW many years ago and I can remove the screws today with a small screwdriver. Magic stuff.

About the only way to keep the frame from rusting is to seal it usually done with an epoxy paint but this usually requires some disassembly.
The other issue is setting the frame directly on a concrete slab.
Either use isolators or building frame insulation.

What I've also done on standby units by the ocean is replace the frame with aluminum or stainless.

It depends on how crazy you want to get. For a couple hundred bucks you could have the frame cad plated or electroless nickle plated and it will last forever, especially if you paint over those platings.'

But probably the easiest thing to do is to paint that steel frame with POR-15

Isn't por just like ospho in that rust or oxidation has to be present to really work.

I know ospho on new stuff doesn't really do anything.

Yes they are very similar. POR sells a primer for new non-oxidized metals.

POR 15 is a single part urethane that can be painted over tight rust to seal it from further moisture.
