I assume that you also have the 220v compressor, otherwise why would you keep the original plates.

Unless you are planning to put in a 24v compressor to drive the old plates, I did not think that was an option.

To be honest, I have only used the 220v compressor once since I had the 2 24v systems installed, but its a reassuring backup.

My old system (220v and Engine Driven) was switched to R502 a long time ago, and as far as I know is still the same.

I have enclosed photos of the combined plates in the fridge and freezer.

So my original plates are running withR502.

You are right the original plates can be used, but I do not have an answer to new refrigerants.

Each plate has 2 coils, and by adapting the connection they should work.

Evidently we left them in place to use with the shore power, but did not go to the expense of modifying the connection to use the old plates as the refrigeration kits came with cooling plates and it was cheaper and quicker to install them.

Here are the photos:

I decided to move to electric refrigeration

The main advantage was that I could have 2 so that if one stopped working, I could use the other and always have some refrigeration

second they keep the content at a constant temperature, whereas the engine driven fridge went to extreme variations, and required the engine to be run at least every 12 hours.

Also, I was having constant problems with the engine mounted fluid pipes, due to vibration.

I have been very pleased with the results, I can run it all the time in port and keep food on board (Battery charger)

They use very little power, surprisingly.

I have a sea water pump for the freezer and air exchange for the fridge

But its not cheap and the manual labour costs more than the units as always:

 Fridge installation (done in april/mai 2012)

–       Dismounting the old frigo boat installation (belt driven part in the engine room and heat exchanger part behind the port side settee)

–       Modifying the freezer volume with an increase of insulation foam thickness in the “against the hull” part

–       Creating an adapted shelf for the new compressors

–       Installing a new sea water filter for the freezer compressor cooling part

–       Installing a new Frigomatic fridge set behind the port side settee

o   Air cooled compressor FM200

o   Evaporator 130H

o   thermostat 

–       Installing a new Frigomatic freezer set behind the port side settee

o   Water cooled compressor W50F

o   Water pump in 12V with its tension reductor

o   Evaporator 400H

·      thermostat 

Manual labour  3 600,00 € (ex VAT)

Refridgeration, Parts and materials 2 900,00 € (ex VAT)

Do you have any experience with replacement of the compressor and condensor of the fridge on board ?  After 20 years of excellent service,  I see the compressor started leaking oil and it might be better to replace the installation especially as the actual condensor is still operating with R 22 which will be difficult to obtain in the future.

I have a quotation from the yard for a Frigomar replacement of around 5400€ not including installation and find this quite expensive. What is your experience ?
