ARP Refrigerator Protection

How bout just installing a small button fan and run it while traveling down the road, would this work as well without dishing out 195 bucks ?

No what the ARP system does is to basically not allow the liquid in the boiler tube to get too hot due to lack of circulation and or volumetic flow which causes the liquid to get hot enough that the Al Chromate (I think that's the coolant/heat transfer liquid) crystallizes out and is deposited on the interior of the boiler tube. What this does is reduce the concentration of that chemical in the ammonia mix and also restricts the flow of the liquid thru the boiler tube where the heating occurs. This is somewhat analgous to Plaque and hardening of the arties in a human, it's cumulative and when has restricted flow enough your refer dies or the human has a heart attack. This boiler tube temp issue have very, very little to do with the ambient temps or external fans. The external fans and ambient temps mainly are an issue in reducing the temp of the fluid/gas mix after it has gone tru the evap coils at the top of the refer so that the mix entering the boiler area at the bottom of the frig is all liquid and not a mix of liquid and gas.

DISCLAIMER: I think I have all the above correct, but not being an actual refer expert I claim the 5th if I got anything too far wrong in the above info. Some might not be 100% technically correct, but I think the general "GIST" is there and fairly accurate.
