Dash Air
« on: August 18, 2007, 01:21:06 PM »
There have been threads on this several times, but I thought I would start a new one and tell you what I used.  You can see the unit I chose at:  http://www.thermokingnw.com/Products/RedDot/R5045.asp.  For some reason the Red Dot site does not seem to be up, or my link is not good, but the one I just sited will give you a lot of details.

This unit is rated at 33,000 BTU cooling and 46,000 heating!   

I have the heating hooked to one zone of my Aqua-hot and it really does the job!  Nice part about it is that it will defrost the windshield before you even start the engine ;D

The Cooling is fabulous.  I hooked it to the truck compressor that was on the Series 60 engine.  The compressor is Climate Control ET-210L-25150. 

The unit can be made to fit in the dash area. 

The BEST part of the evaporator is that there is a control to divert the air from the front outlets you see in the picture to a rear opening.  That opening in an ambulance or armored car diverts the output from the front to the back (or through wall).  For our application, you can make a manifold with tubes to hook to the existing defroster hoses.  Viola, you have defrosters AND heat/AC. 

The controls are such that they do not allow running of the AC when you are defrosting, but a simple push button switch would allow you to activate the compressor for short periods of time to defrost the windows.

For our application this is a SUPER system!  It is a bit expensive (I was able to find an old stock slightly damaged unit for quite a bargain), but it is simple and really works!

Jim,did you use copper or rubber for the lines and is your condenser a remote mount with the fans, one more question where did you run the lines in the tunnel or some other place.the reason i am asking is because this friend of mine doesn't want his in the tunnel and i don't know any place to put them but the tunnel

I used rubber hose (barrier for R134) all of the way.  It was pricey, but I got a good deal from a local firm that wanted out of the business.

My Eagle is a 10 with the AC evaporators (? I forgot what was in there) in the compartments on either side of the fuel tank.  I had emptied those areas out.  On the driver side, my shower drain is taking up part of the area.  I ran 2 inch PVC tubing through both compartments (3 each compartment).  I did this since my tunnel is pretty full.  I ran each of the two hosees in separate tubes along with some other utilities in the driver side tubes.  The passenger side tubes will have hydraulic hoses for the front jacks and room for more utilities.

Hi Jim,

I have to admit I have not seen this unit before.. I have worked on alot of Thermoking Reefer units and diddn't know they had them available.

By the specs. it sounds great and with really good cfm's.

Good Luck

Nick, the evaporator is made by Red Dot.  Tonight their site is up and running:

http://www.rdac.com/Pages/product_pages/units_pages/5045_unit.html

Clifford, the compressor was a Climate Control piston type unit that is used on many trucks.  Mine was a 210 model.  You can download the service manual from:

http://ccicompressor.com/SrvcManl.aspx

The service manual says that it comes new with 14 fl. oz.  I bought a new one, since I did not know the history of the one on the engine.  The manual tells how to check the oil.  I don't think that mine had the full 14 fl. oz.  I made sure it had a bit more because of my fear that the oil would get dispersed in all of the new hose and equipment.  After the system is charged, you can't check the oil level.  However, I managed to let the hose get into the new house alternator I was installing (don't ask >:().   Obviously I lost my charge and I then took the opportunity to check the oil level after my first trip to OR.  The oil level had really not dropped much (was still at the 14 fl oz level as I recall).

BTW, for the long hoses I used the Aeroquip GH134 hose with their new E-Z Clip system:

http://www.eatonhydraulics.com/products/pdfs/fc/A-HOAC-MS002-E.pdf

That made the repair of my hose very quick and easy.  It was the suction hose I messed up.  I simply cut the clips off, cut the bad end of the hose off and reinstalled the coupling using small worm type hose clamps.  If you want to crack out for the pliers that install the clips, you could couple all of the hoses yourself very easily.

Jim,thanks i found the book on my Denso compressor and it takes 17.4 fl.oz. and 1/3 of a oz. for every 20ft.  the compressor he has looks likes a Chrysler from the 70s and it has no numbers any place on it he should buy a new 1 made in this century but he is real conservative(cheap).anyway tell Pat hi and we will see you in CO.Springs next month
