Re: Dessalator 24v watermaker motor expected brush life? Anyone replace theirs?

Ian,

Maybe this helps. The 220v doesn't have brushes

Hi Scott,

 In 21 years since new we have done at least 2,000 hours on our 60 lph Dessalator--we may have done more than 3,000, but I am not on the boat at the moment. That would be a mixture of 220v and 24v.    I can't recall changing brushes on the 220v motor but have done so once on the 24v.

Subject: [AmelYachtOwners] Dessalator 24v watermaker motor expected brush life? Anyone replace theirs?
 
Have any of you had to replace the 24v brushes on your Dessalator 24v water maker pump motors? I am guessing the motors are similar across the range, but to be specific, the 24v motor on our Duo 100 is the Drive Systems V745.

A fellow A54 stated that they've had to replace theirs every 500 hours of use, which seems quite low. As a basis for comparison, my Flojet fridge water pump motor brushes averaged anywhere from 2000-3000 hours running 24/7 and the Marco engineers I spoke to told me to expect the same from their brushed motors.

We are now in the South Pacific with about 500 hours on the 24V motor and I am getting a bit nervous. Desslator stated that "We can’t tell you how many hours last the brushes, it is too random, there is no really “rules” for that."

And unfortunately, due to supply chain issues, it will take 2-3 months for Drive Systems to manufacture them and cost around 300 euros for two sets of them. The price is even higher from Dessalator.

Re: SM Main Furling and outhaul gearbox - Bonfiglioli substituted for Leroy Somer

michael winand
 

I have changed the main sail furling motor and gearbox from the leroy somer gearbox to the bonfiglioli. 
I had new mounts made for the gearbox to the mast, they are slightly different, this way I can change back. 
The inside diameter of the gearbox drive is smaller than the leroy somer gearbox, I had a new drive post made to suit, you could machine the gearbox to suit the existing post that drives the furling gearbox, this will allow you to use the bonfiglioli on the outhaul as well.

Re: Updating the Furuno GP-150

Scott SV Tengah
 

Arno, very happy to hear that you were able to update it yourself. You didn't have to jumper the flow control wires per the Furuno instructions and my conversation with Furuno Australia? I guess setting flow control "off" in device manager achieves the same?

That is what is stopping me.

The above install is on my Mango using a B&G Ram T2 linear drive and a B&G NAC 3 AP computer. I have the original AP still working well. Redundancy is good to have.

Dear all,
why not installing the drive unit next to the rudder shaft?
We did this on our Sharki two years ago and we are very pleased with the performance and mo noise to hear in the cockpit.
We used the Jefa DD1 drive unit together with the Raymarine 200 autopilot, installed in addition to the original Autohelm autopilot system installed by Amel.

Hi Alex

Would be great to have more info and pictures of your hydrovane installation. Something I am considering for my Maramu in the next year or so.

Thanks

Re: Maramu replacement autopilot drive motor

Hey Ben,

Here are a few pictures, the install was made by the previous owner, so I don't have much insight, we don't have anything to complain about, it behaved really well, The unit in the galley is noisier than we'd like though, not too much but definitely was a factor to order a hydrovane for our upcoming atlantic crossing, after 3 days of autopilot in the bay of biscay.

Good luck with the install and don't hesitate if you need more info.

That sounds very reasonable. It allows for DYI but requires a decent BMS with logging capabilities and presumably a well documented installation following best practices. That’s about as good as could’ve been hoped for. Which insurance company was that Mark?

Re: Introduction - and some help on fridges pls

Bill Kinney
 

Another reason not to sweat too much the efficiency of a front loading fridge:  Air is very easy to cool down.  Even if you managed to exchange ALL the cold air in the fridge for room temperature air the energy cost to cool down that warm air is a small fraction of the energy needed to cool ONE warm beer down to 4C.  And the energy needed to freeze water into ice is almost another order of magnitude higher again.

In short it is TECHNICALLY true that a top loading fridge is more efficient ALL OTHER THINGS BEING EQUAL, in the real world the loss of cold air when opening a door is a negligible part of the fridge’s energy budget.  This is especially so if you need to leave the top loader open longer because things as less accessible.

Far more important is better insulation, and especially more air tight door seals.

This: "...full records are to be kept. Ha! What is the definition of "full?" Probably something different from what you have.

If you have Lithium batteries, that policy, and probably any claim, look for a denial.

Bill,
I agree with you that a water cooled system for the freezer and fridges are the best solution. But I don’t agree on using sea water. It will cause a lot of trouble with barnacles in the water inlet and hoses.
It is much better to use the fresh water tank as the cooling source. Not only that you get rid of the barnacle problem, you can also run the fridges and freezer when on the hard. The additional warmth in the fresch water tank is so small that you can’t messure it. Meaning less than 0,5 degrees C.
We have had this system on S/Y Lady Annila since 2007 and have never had any problems with the cooling system or the quality of the water.

Tom,

It is true that top-loading fridges and freezers are more efficient because front opening doors suck more than half of the cold air out of a fridge when you open the door. I suggest that efficiency is NOT the only measure of what is best for you and your Amel. As an example using circulating seawater is more efficient than air to transfer heat in the refrigeration condensing process, but as everyone who has this will tell you, circulating seawater in the tropics is problematic. And with the power available on most Amels, following the efficiency rule, in this case, is NOT the right thing to do. 

Probably the number one factor will be what will fit correctly.

Thanks Ian - the Isotherm Cruise Drinks Fridge seems a very suitable as a direct replacement for the original fridge. I wanted to also explore whether there are other options out there as the previous owners of Saol Eile (who spent 6 years aboard circumnavigating) say that maybe a top loading fridge is best for tropical climes - they always felt that opening the door on the side hinged fridge lets all the cold out and is very hard on batteries. I guess I will take my time and do more research.
