A week or so ago, I published Robs Fan which showed how clever people can make their European (or any fridge) perform better by simply expelling warm air from behind or in Mike’s case, circulating cool air as well.
Both are novel ways of getting much better performance and both work briliiantly.
Mike and I were at school together a hundred or so years ago and where I went on to be a newspaper photographer, Mike became a very able Gasfitter and Plumber and clever with it.
Mike recently purchased a very nice new A class Rapido from an elderly chap who imported it from Europe but due to a change in his circumstances, couldn’t keep it.
Fiona and I caught up with Mike and Wendy at Shakespeare Bay for a very nice lunch not long after they got their van. I published an article then and you can see that here.
The Rapido has a 90l Dometic fridge in it and since Mike picked it up has been very unimpressed with its performance and ability to keep things cold. After reading Robs Fan, Mike decided to sort it once and for all.

Here is what he did in Mikes words.
Hi Chris I've just finished installing three fans to to accommodate the cooling for a Dometic 8505 fridge freezer 90 l. All items were purchased from Jcar. There are two 120 x 120 x 25mm fans fitted in the cooling tower. The top fan is fitted 150mm below the cooling fins...connected via a 50degree temp thermostat. Duratech: YX-2574 Air flow: 37 (CFM) Current: 0.08A Fan Speed: 1000 rpm Noise: 20.2dBA The bottom fan is fitted 100mm above the top of the bottom air vent...connected via a 70degree temp switch. Duratech: YX-2584 Air flow: 64.3 (CFM) Current: 0.22A Fan Speed: 1500 rpm Noise: 25dBA The fridge fan: Duratech 90mm: YX-2572 Air flow: 31.32 (CFM) Current: 0.13A Fan Speed: 1500 rpm Noise level: 20dBA Each fan can be independently controlled by an on/off switch installed inside the motorhome. The results: Motorhome vents in full sun: Ambient temp 27.1 degrees: Fridge on setting three: 1) Even temperatures through out the fridge at 4degrees. 2) Freezer -10.7 3) On setting 5 the freezer got to -17degrees Before I had a shit fridge...now I have a master piece. Regards Mike.
