I hunted for years for a Servel for my rural home. I finally found
one, not ready to pay thousand or so bucks for a new one.




A little OT, but when I was growing up in coastal New England, my parents
got a Servel. When we had bit storms or a hurricane, it was over loaded with
stuff from the neighbors that were without electricity. I lived for a time
in the Cleveland National Forrest, in southern Californian, and the little
cottage had one that was run off our propane tank.

I have to agree with Bruce. As one who has designed a number
of commercial and industrial electronic products, I'll be the first
to admit designing to minimum RFI is a pain...mostly the testing
to make sure it was done right...but the techniques are so well
known it isn't rocket science anymore. There's really no excuse for
electrical equipment to cause RFI, either conducted or radiated.

The yachties have been conditioned to accept RFI tearing everything up.
After all, their whole damned unshielded NMEA network with the screw
terminals, bare wires, unshielded cables and connectors are RADIATING LIKE
HELL into everything with a receiver......dammit all.

Look at the wires hanging out of your electronics....all of
them....balanced, unbalanced, unshielded.....damned NMEA cheapskates.

Jax,
I'm on the way to another job and going to take this time to respond
in-line (a method I personally do not choose)

I kind of hate to tell you this, but maintaining the liquid fill in the
generator (you called a burner pot?) is actually pretty simple.

yup, I think I said that right from the start, as long as the boat is rocking
around a bit, but NOT in an RV parked off level more than a few degrees.

In the prior note you said this would be tough to do. Our program
target was 1g latteral without blowing the seals and we quickly
discovered that if it did that the operation would be satisfactory at
any any acceptable for and RV. One of my pepole decide to see how far
out of verticle the last protoype could be fired and remain operational.
The rig he built could only do 27deg. He is still using that unit in
his RV.


it will function properly at latteral loads to 1g

more than 1 g actually. much more.

I was not aware that you were part of our team and setting our design goals.


Wouldn't that would be close to a 45 deg heel?

no. lateral loads and degree heel are not interchangeable terms in this issue.

Can you please tell us why not?


The last people that called me about this project a couple of years ago
bought consulting time

ah, THAT proves you are knowledgeable, doesn't it. someone paid you money to
hear you talk.

When was the last time someone paid you for your opinion?


They were looking at a system to include in powerboats.

then they were wasiting their time. powerboats have excess power available
compared to the power needs of a reefer system.

Many smaller powerboats do not have a ship's service generator. Many
also do not have very extensive DC as they are running the alternator
that cmae with the engine package.

Ventilation became a serious issue. That would still be an
issue in good boats.

nah, a propane reefer has such a tiny flame is hard to tell the unit is running
unless you hold your hand over the chimney for upwards of thirty seconds or
more.

If you are so sure, please close yourself in a boat cabin with a fire
going for a day. You might notice the moisture accumuation that is a
by-product of combustion before the oxygen depletion is apparent.

Nice talking to you, I have to go.
