Ice-Box Conversion to Fridge

Last year, I posted a blog about my plans to install an Isotherm Self Pumping refrigerator conversion – and this year I have finally completed the job. It works!

The ice-box, now refrigerated, is to the left of the cooker, and the compressor gubbins is to the right, in what was the trash container (that I used as a dry food store). I fitted the compressor to the bottom half of the compartment, and put a clear Lexan cover over it, to protect the unit from spilled water from the taps. I will fit a drain, to take spilled water down under the sink.

The evaporator is fitter to the ice box, which had no insulation on the engine-side, where the fridge used to be. So I fitted some closed-cell insulating foam board – the purple stuff, an offcut of which I have used to act as extra insulation for the lid. I will seal this piece to make it more durable.

Now, I need to seal the windows, to stop rain and seawater from leaking in and draining into the icebox. The great news is that a couple of cooler blocks and some bags of ice in the bottom of the icebox stay frozen, and there is no compressor noise, nor is there any pump to consume battery power whilst under sail.
