Title: Need Alternative to Stock Defroster
Post by: sparkplug188 on October 10, 2014, 10:08:18 AM
I need to come up with a working defroster for my Eagle.  The existing unit and lines were in bad shape, so I removed them and caped the lines back at the engine.  Does anybody know of a 12 volt (or 120 volt) defroster?  Heat and air conditioning is already taken care of by 48,000 BTUs total from mini-splits.  I just need something to satisfy the DOT requirement of a working defroster.

Just tossing it out there.....

How about a 120 volt electric hair blowdryer? It can be ducted easily, most have lower heat settings,
120 volt is no problem you say.

Check out the DC Thermal site they make a lot of 12 v heaters but low watt and high amp draw I have one in a 05 but never used it so I don't if they work or not

I've seen electric defrosters advertised for kit cars and stuff - whether they'd be any good on something as big as a bus windscreen though....

It's also worth just trying to blow cold air at your windscreen as that will often go a long way towards defrosting it (depending on your climate and how dry the air is)

Thanks guys!  By this time next week, my bus will have a DC Thermal defroster installed.   ;D

   Go to Red Dot company; They have many solutions for heat, AC, and/ or defrost that are used in commercial vehicles

I put a DC Thermal unit in my Silverside, up where the destination sign scroll used to be.  The PD3751 had factory heat duct slots cut in above the windshield so it was a slam dunk.

Boomer-- I am glad you mentioned that.  Are you satisfied with the DC Thermal unit blowing from the top of the windshield?  I have about 3 cu.ft. of unplanned space above my windshield... more than enough room for the DC Thermal unit.

To be perfectly honest I have never used it.  Don't drive in conditions that would need it.  I went with the lowest CFM unit and it does not seem to blow at much velocity but may be enough if you needed them.  Have a fan mid point above the windshields, the combination of the two are probably good enough.
