Okay, last one (I promise)..... C4 versus DCH538

[Red Green]

Okay maybe I won't promise but if I ask another one of these types of Q's you can kick the crap out of me in the alley behind the nudie bar.

Seriously, C4 vs DCH538 and specifically why/why not....

 

[Desk Jockey]

DCH538

What is that?

If you buy from a company with no distribution network you'd better ask more questions about the COMPANY than the machine.

Butler has that model, but they have a 40 year track record and they make it work well.

 

[Mikey P]

Pretty much the same thing.

What heat source do you want and is ten years of of your tank enough for you if you go with the Cobbjob

I'm tickled pink. Finally something that Richard hasn't heard of.
There's still hope for me.

I was serious. I'm not that familiar with his units and had no idea what it was. I googled it and nothing came up.


I'd say they are the same, I've not owned either but have read from members posts that like each brand. Neither have a distributor network so get the one that gives you the most bang for the buck.

 

[Mikey P]

Jeese Outofcharactor Enos from Vegas is getting one of those with a R/O unit real soon and if all works out the Cobbjobb should be at the MFE in September


Both units are ugly as can be so that should make your choice easier.

it will mainly come down to if you want heat exchange or a propane fired heater.

wich do you have experience with?

Hey Larry that was me this afternoon, we talked about dimensions and how your heat exchanger works/diverts, the connection was bad because I was on the road in the mountains (long day).

Anyway I am a bit stumped about the measurements we talked about height wise of 55". On the page with the 538 you show an install in a customers GM van and there appears to be about 3-4 inches of clearance, yet the GM only has a max height of 52". I thought maybe I had written the numbers down wrong so I called the sales gal back and she checked what she had written and it was 55"?

Did you use a lower air cleaner on that GM install or am I missing something? I ask because I picked up an NV which is about 3" taller than the GM & Econoline. And when I did call back to check what I had written she did state that you had done 538 installs in both the GM's and Fords.

I'm scratching my head here.....

The height that GM uses is the door vertical distance.

The H.D. Air Filter we use (200 hr maintenance) is taller.

We loosen it on the install, to clear the door.

There is plenty of room inside the van.

HX only, and they were all used second hand units, so maybe my opinion of them is a bit too bias based on my lousy experiences with high hour stuff. One of my first TMs had some decent heat and customers always got jazzed by the show of steam at the wand (theater at its finest), but most were shower hot and a few I simply bypassed the HX because they didn't work. Now that I'm prying my cheapskate wallet open on a new one finally, I want some HEAT.

 

[Mikey P]

This unit was VERY hot.

[Red Green]

I'm still confused, I just went over and measured my neighbors Express and side door height was 48", the highest clearance on the roof was 52.5. In your 538 picture it sure looks like there are at least a few inches between the AC and the ribs. Something on this isn't adding up as the NV has the GM beat by several inches yet I would have to cut a skylight if your measurement really is 55"

Actually larry, the Briggs has a 3 year commercial warranty.
my Tri-lobe is 550 CFM
Stainless steel tank VS. cheap steal?

 

[Larry Cobb]

Mike;

A 4" gear tri-lobe blower MUST be turned faster to deliver the same CFM.

The Judson reference video above says 2 years.

We don't use any steel in construction of our tanks.

I'll double check the height tomorrow.

Larry

 

[dealtimeman]

larrys tank are aluminum, but i believe if you forked over a couple grand extra he could have them made in stainless. actually i believe he has made some in stainless for some of his customers.

i have seen a couple of the #5 blower machines in chevy vans and they fit fine.

 

[Red Green]

Sounds good, did you guys maybe include the pallet it was sitting on?

Yea if the big 538 fits in a Chevy I'll have even more clearance in the NV as it's taller.
A stainless option would be something I would consider paying extra for if the price was right.

Between the two I like the overall layout, the stainless, and potential heat of the C4 better, but I've never dealt with such a heater so that worries me a bit.

On the 538 I like the bigger blower/motor combo better, along with the lighter combo-tank and the idea of simpler heat production. Honestly about the only thing I don't like about it is the PVC blower pipe, I'm sure it's fine, but every time I see it I cringe.

What type of work do you do? There are certainly pro's and con's for propane. It your work demands extremely high heat I'd lean more towards propane. If you do more moderately soiled and you heat demands are less you'll save both the cost of the secondary fuel source and the hassle of dealing with it. Propane heaters are easy to operate, buy the second time you light her up, you're an old pro.

The DC538 has metal plumbing on the blower:
View attachment 5030

The DC534 has a couple of NYLON threaded fittings on the intake side and all metal on the outlet side.

We also offer the tanks in SS, but most of our well-braced aluminum tanks last over 20 years of heavy usage.

[Lee Stockwell]

Quite a reducer there...

 

[Desk Jockey]

Is that galvanized or aluminum? It looks like plain pipe?

If it is I think I'd pay what ever the extra would cost for aluminum and not have to worry about a chunk of corrosion falling into the blower.

 

[Mikey P]

no kidding, why choke it down asap?

 

[Lee Stockwell]

Some galvanized pipe distributor in TX has made a killing selling 2" elbows to the garage builders.

 

[Desk Jockey]

Lee wouldn't you consider that risky for very little savings.

 

[Lee Stockwell]

Yep
