Needed Webast0 .40 Atomizer Nozzle

bryanhes · November 22, 2009, 06:02:56 PM

Any suggestions where to pick up a .40 nozzle? I tried a couple local heat and air companies with no luck. Nick, have you got any?

Thanks,
Bryan

Bryan, call Kraft Tours in Tulsa ask them he had a few buses with the Webasto.
I see you live in Patti Pages home town.
I built a few banks and shopping centers for Frank Robinson (RCB)

good luck

I will check with them. Small world. I bank with them. Did you build here locally? I work for Pella only commercial projects. We have been here for a little over three years. Its a nice small town yet close enough to Tulsa to make it convenient and out of the crime rate.

Thanks,
Bryan

Hi Bryan,

I stock the .35 nozzles which will make your unit more efficient, and burn cleaner.

15 bucks + ship

Nick,

I spoke to Brian in the tech department at Webasto the other day. He said depending on whether I had an 8 or 10 bar something or other. He said I should have the 8 bar because the age of the unit and to run a .40. It is a 40,000BTU unit and not the 45. It is a pre- 1995 unit. Maybe mid to late 80's. I have not run it yet. Bought it off the Spare Tire board. Took the heat exchanger off and pulled the canister. Everythibg looks good and as it was not run a whole lot. Just thought I would go ahead and replace the tip since Webasto suggests it every year.

Thanks,
Bryan

I've had two Webasto DBW2010 units. Both take the .35 nozzle. Webasto has upped the pressure to increase net heat output to 45K BTU from 40K. however, the nozzle is still the same at .35 at 60 degrees.
BTW the cost of a new DBW2010 is now about $4K.

The 8 or 10 bar is a pressure rating. I think it is a European thing similar to our PSI Jack

BAR stands for barometer.
At sea level we have 14.7 PSI that equals 1 BAR
So to change BAR to PSI just multiply it by 14.7

BAR stands for barometer.

You have that backwards.

"Bar" means "pressure" -- defined by British meteorologist William Napier Shaw and derived from the Greek "baros" meaning weight.

A "barometer" is, therefore, a device for measuring pressure (think bar-o-meter).

One Bar is 100 kPa or 0.987 atmospheres, making it approximately 14.5 PSI (not 14.7 as you wrote).

FWIW.

Sean,

I have to tell you your posts are always very technical. You must look this up online before you answer or should be on Jeopardy!

Thanks for the info. I actually looked it up in my service manual and figured it meant pressure.

Busted!

Really, who can remember stuff like one bar is .987 atmospheres? I can't remember Avogadro's Number, either (but for some reason still know the value of pi out to nine decimal places).

When these sorts of things come up, what I remember are things like the fact that a bar is an even decimal fraction of a Pascal, and that an atmosphere is a weird fraction, and then I look up the details so I can provide a more complete answer. (Don't get me started on how frustrating it is to me, as I suspect most engineers, that we are not using SI units in this country.)

Neither did I remember that Sir Napier Shaw was the fellow who introduced the Bar as a unit of pressure. But I knew that the words bar and barometer had the same root, which I knew to be Greek, and that bar did not stand for barometer any more than volt stands for voltmeter. I looked up the specifics.

Now my secret is out....

Of course, looking things up is a bit easier if you know how to tell meaningful search results from red herrings, too.

And I thought Bar was a place o congregate for a cold drink

A little info on SI:
The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent.

Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units.

Have I taught anyone anything yet? Ok, I really do not understand it either but am glad there are people here who can when I really need to know!

Always appreciate the advice

Got it! Thanks

I found out last night after looking over my fuel pump that it is a 7 Bar. In talking with Webasto I would either need to stay with a .40 nozzle or upgrade the pump to a 10 Bar and can use the .35 nozzle. The tech said it would not work well if I tried to go to the .35 without upgrading the pump. And they are proud of the upgrade kit.

Nick do you have a .40 nozzle? And how much?

Thanks,
Bryan
