Protecting "shield" for evaporator in aggresive enviroment

[infoseaker]

Hallo,
we need to protect evaporator in aggresive enviroment. I know, there are special evaporators designed to survive in such enviroment, but those are too expensive.
Any ideas about suitable colour/varnish for evaporators?
Thanks

Hi there
What type of agressive enviroment.i live in a sulphur area in new zealand the enviroment here can be extremely agressive brand new units going down within a few week with porous coils or is this a different kind of agressive

Google "Blygold". Australian based (I think) company just recently set up here in NZ, they might be in your part of the world somewhere. Quoted us on some work, but for other reasons we didn't use them. Looks like a ok product.

It is production line with a lot of saltpetre in air.

I have sent email to Blygold... and waiting for response.

You could try powder coating the coils and then completely cover unwelded and welded loop ends on coil with a silicone this method is well tried and tested with my company
