Re: [Amel Yacht Owners] Capacitors for 160 AC Dessalator

When we first got on board that is what we did. We dialed back the pressure to remain at 150l/hr or less. However, when we had to replace the black box controller on the HP pump, I had several in depth discussions with Martin at Dessalator to better understand the process and the systems. Martin stated that it is perfectly safe to run the HP pump on the high side of the green of the HP pressure gauge just shy of the redline. He said you could run the system in this configuration 24x7x365 without any issues or harm to the system.
 
So we have been doing this for the past 2 years. The output of the water maker will depend, to a large extent, on the water temperature. The higher the temperature the higher the output. Ours ranges between 145 to 175 l/hr. Martin mentioned that the rating of 150l/hr was placed on the system to make sure that it would produce that amount in the most adverse conditions.
 
Most of my information is from Martin and have not done much research on the matter. However, I have found Martin to be very knowledgeable.

Gary & Mohammad,

The Dessalator D150, later named the D160 went through lots of changes, with the membranes being about the only part that remainded the about the same in all models. I said about the same because when Dessalator made the D150, each of the two 25x40 membranes was rated at 75 liters per hour at pressure. Filmtech changed manufacturing of this membrane, increasing output to 80 liters and Dessalator renamed the D150 to D160. 

BTW, some owners produce more than the rated numbers. You should not. Dial back the pressure knob so that output is correct for your membranes. Too much output and/or too much pressure will shorten membrane life.

How to flush Volvo D3-110i-C

ya_fohi
 

Hi,

I'm looking for some advice on how to flush the raw water system on my Volvo D3-110i-C. I know it has debris/salt etc. build up because I can feel it crunching in the rubber hose when I squeeze it, and also the engine which normally runs a 78°C at 1250rpm is now running at 83°C or higher.

Any advice would be much appreciated.

There are no "partial failures" of diodes.  As solid state devices they either work--or not.  When they fail they fail "open" and block current flow in both directions.

It is possible, I guess, you could have a short circuit inside the alternator somewhere, but the chances of it working at all would then be pretty close to zero.

Hello fellow Amelians,


I have had a great passage to the Azores from Antigua (14.5 days). 


Some months ago I asked  the forum about exciting the 24v alternator and was advised by Bill to check the relay and excitation circuit  which I did. However I still have the same problem that the alternator needs 1500 rpm to "kick in". Once kicked in I can throttle back idle and still charge.


No big deal right.....well yes and no I am beginning to think that maybe one of the diodes is defective and that I might have a small current drain through the alternator. Does anyone know if a diode failure is compatible with the general history I have described?

Unfortunately I had to catch my plane so I only turned off the master red handles for the batteries. Thinking that the batteries would be isolated.


Now back in the UK, unable to check the boat I am worrying. If I am correct, the red handles do not isolate the chargers or the 24v alternator from the battery bank. Thus if there is a diode failure on the 24v alternator the batteries could be leaking despite the red handles being turned off. This could be bad for my anodes and prop for example not to mention the battery bank. Does anyone know if the red handles isolate the 24v Alternator or not.

Shore Side Circuit Breaker Tripping When Plugging in Boat

pacificcool@...
 

I have a 220 volt Super Maramu from 1995 (#141) which is currently in Fort Lauderdale waiting to be sold.  I moved to a new dock yesterday and when I plugged into the 50 Amp shore power outlet, the circuit breaker in the house tripped.  At the previous dock (where i had stayed only two days), there was only 115volts with a 15 Amp circuit breaker.  Before plugging in to the first house, I turned off all 220 volt circuit breakers in the boat except the battery charger which can accept any voltage per the manual (it's a Victron 80 Amp charger).  The GFI tripped and would not reset.  I suspect  something happened there that affected my boat.  Maybe a fuse blew or a hidden breaker tripped, but I cannot find it.  


Does anyone know if there is a fuse or hidden breaker that could be tripped?  Or can anyone suggest a fix?

Re: Alternator and Masse leak detector

Alan Leslie
 

Hi Nick,
Have you checked the alternator belt tension? If the belts aren't tight enough they could slip at low revs and therefore the alt won't charge.
It could also be a blown rectifier in the alternator...you need an auto electrician to check that.
The red handles only disconnect the batteries from the users on the boat. The alternator output is wired directly to the batteries.
If you have a rectifier failure in the alternator it is very unlikely that would lead to the Masse -ve light being activated. 
Diodes generally fail open circuit not short circuit.
The -ve masse light indicates that you have a connection somewhere between house bank -ve and the bonding system (ground). The most likely cause of that is something that is 24VDC powered and also has metal parts in touch with saltwater. The macerator pumps in the heads are the usual culprit, but beware of AC devices such as laptop chargers which may internally have -ve connected to ground and that will feed back through the system if you have the original Calpeda A/C pump...that is where the AC ground is connected to the bonding system.
In summary i don't think your alternator issues are associated with your -ve masse issue.
Good luck
Cheers

Re: [Amel Yacht Owners] Capacitors for 160 AC Dessalator

Mohammad Shirloo
 

Hi Gary;
 
I do not believe that the reason for the two capacitors is to achieve a different capacitance level by wiring in series or parallel. I believe they serve different functions. One is a start capacitor which provides the initial large instantaneous current required to start the motor and the other is a run capacitor which dictates the direction of rotation.
 
If any one goes out, the motor will not function correctly. The capacitors on our HP pump are connected to a black box controller by Lafert. My information comes directly from the main technical support person at Dessalator Martin Dee Jong. He is extremely knowledgeable with Dessalator products and am sure can help you further if you need it. His number is             +33 607346511. He is typically in France and is very good at responding to calls.

Thanks Gary!  Great source for the part.  After posting I had done a bit of examination to see that the stud was just for mounting.  This may explain why our Dessalator seems to still be working OK. I don't have an IR gun but it is high on my list!  If we can, we will make the temp measurements.

Re: [Amel Yacht Owners] Capacitors for 160 AC Dessalator

Hello Bob;
 
We have the 150 l/h dessalator. The HP pump motor is the LAFERT AMME 100L BA4 50HZ 230V 3.0HP 220-240V.
 
The two capacitors are:
 
  1. 70 microF +/-5%, AC 400V AC 450V 50-60 Hz. Ours is made by ICAR Italy
  2. 180 microF -0+20% 220 Vac 40-60 HZ made by FACON Italy.
If you have the same motor, this information may be of use. Of course the brand of the capacitor would be irrelevant. One important item to keep in mind, is the resistor that connects the two poles of the capacitor, I believe for discharge after power down. When we changed ours, we unsoldered the resistor from the existing capacitor and re-soldered to the new.
 
Hope this helps. Let me know if you need any additional information. We are not on board but have detailed pictures to reference.

Does anyone have a part number or source for the 2 large black capacitors on the high pressure pump for the Dessalator 160?  They both have a stud for a nut on one end to fasten (and provide electrical contact) to the pump bracket. Ours still work but are falling apart physically-- I've got them held together with cable ties and need to replace them at some point.

Re: 2001 Amel SM (Norfolk) HIN 1045353

Brent Cameron
 

This is going back a bit but I've been looking at all of the old posts trying to gather information on the SM's to help with my search and help me narrow down what I actually want.  From what I've been able to tell Bill, the Amel 12 Letter serial number system for the Super Maramu's works like this:

First three letters are the company (AML)
Letters 4&5 are the Model (SM for Super Maramu)
Letters 6,7 & 8 are the Hull Number (387 in your case)
Letter 9 is the Month as you say (where A=January, B=February.... L=December)
Letter 10 is the last digit of the year it was built (in your case 2002)
and then the last two letters (are the model year - in your case 2003)

I've looked at dozens of SM's and they all fit that pattern excepting two very early ones (a 1992 and a 1990 Annie) where the patterns make no sense at all (and aren't 12 digits) which make me think that there might be a transcription error like the HIN above in this post which doesn't make sense either as you suggest.  Those boats are early enough that it is possible they didn't use this scheme (I don't have an earlier data point that would suggest they didn't) but in 2001, the scheme you pointed out was definitely in effect. 

I've also noticed that the point the model year jumps ahead of the build year is somewhere between April and September (with September  being the most prevalent but a few examples of July/April thrown in to confuse things).  Anyway, the more I dig, the more I discover that they are all great boats (with a few notorious examples) and it's just a bit of trivia that maybe Olivier can explain to us.

Bill, I decided not to flush it ,other than with water. For one thing its impossible to get to the engine block drain, without removing things that have not been moved in 24 years, better to leave sleeping dogs lie. That sleeve I emailed you about on the heat exchanger plays an important role , it forces the water (antifreeze) to go through the first two openings in the tube and then out the other end which insures the heat transfer . Not having a sleeve allowed some of my water to bypass the H/E thus the overheating. We just came in from running the snot out the boat , like 2800 rpm for twenty minute and it never went above 190 ,problem solved. So if you have a Volvo TMD22  and have persistent overheating , check to see if you have this small rubber sleeve that slides over the H/E tube , mine had fallen apart over time. Also I bought parts that were $288 for a Volvo here (end caps), for $48 through Parts4Engines  in the UK , but for a Perkins M80T, so buy Perkins not Volvo parts,tip of the day!

Re: Capacitors for 160 AC Dessalator

amelliahona <no_reply@...>
 

Bob & Suzzane:

These capacitors should be 30 uf (micro farad) 450 volt AC capacitors with a stud at the top for mounting and wiring via pigtails.  You can purchase them here:  http://store.eurtonelectric.com/capacitorcbb60-d111uf450vac-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1-1.aspx

Very reasonable price.  Capacitors are usually specified at twice the operating voltage as the device, hence the 450 VAC rating. 

The stud is for mounting only and is not part of the electrical connection.  Only the pig-tail wiring is part of the electrical connection.  

As capacitors fail the motor doesn't run as efficiently and runs at a higher temperature.  Bill Rouse told me his high pressure pump would run at 235 def F under load while mine ran at 197 deg F right after I replaced the capacitors.  I wish I would have measured the temp with the IR thermometer prior to changing the capacitors to see what effect it had.  Perhaps you could do that for the group and measure the operating temp of the motor (just point your IR thermometer at the cooling fin area of the motor) before and after you change your capacitors. 

All the best,

Capacitors for 160 AC Dessalator

Does anyone have a part number or source for the 2 large black capacitors on the high pressure pump for the Dessalator 160?  They both have a stud for a nut on one end to fasten (and provide electrical contact) to the pump bracket. Ours still work but are falling apart physically-- I've got them held together with cable ties and need to replace them at some point.


We've searched the site, but couldn't really find the answer.
