Thread: The Precise Temperature of my Beer

I got this from Arb last year. sits on the dash of the 90 and the fridge is in the back. So as you drive along you can tell how cold your beer is (Ok Ok i know ok how warm my beer is )
Has the same thing as yours so just goes down into the fridge and then has about 4 m of cable so plenty to go to the front of the truck. Cost me $25

Well found one of them temp thingós at JAycar and installed it on the weekend, and it worked a treat, even has a voltage sensor which i hooked to the aux battery so am mighty pleased. Was a bit of a mission getting the wires to the back of the fender (its a dual cab) because i tied em up so tightly went i ran em for the fridge but the unit up the front looks pretty good.
some pics

wot?
no DVD screen??

not flying with this airline again

Ok after having ran my new gadget for a while it seems the fridge just can't handle the temperature out here (40-45C) Does anyone else operate a 40L engle in this sort of temparture and can you get it down to zero in the heat?? I have a bag for it and a twozone so these are a bit of a trade off but should i look at getting it serviced so that it will stay cold in all temparature's or should i be happy with the 6 degree's is stays at during the day?

how's the airflow to/from the condenser ??
Condenser airflow is critical in any refrigeration system in high ambients...

Must admit, even yesterday it was 42 Deg C here, and my little engle still kept Minus 2 Deg C on medium setting.

As Rick said, airflow to the condenser is critical, if fitted is the condenser fan running, is there alot of dust in there. If so blow it out with an air line.

before the transformer( or whatever the hell drives the 12v side of an engle) packed it in my engle used to pull down to lower than -5 (i used to leave one of those scout type themometers in there) on the hottest of days, the trick was to crack the 2 back windows and leave the vents open.

I'm in the process of fitting a fan to my old Engel. A couple of ex-colleagues from OTC have done some playing around and found that the fan really improves the efficiency of the Engel. They found that if the condesor coils get above about 43 deg C, the cooling efficiency of the Engel falls dramatically.

I've been given a circuit diagram for the older style which will help with the wiring in of the fan. It can't be connected across the compressor as that runs at 20VAC.

Another problem with the older Engels is that as the supply voltage falls, the output from the simple multivibrator power supply changes from a clean square wave to more sinusoidal. This impacts on the compressor operations as well.

My experience has been that using cigarette lighter sockets for the 12 volt supply is a good way to lose up to 2 volts in supply voltage across the socket. Unscrew the cigarette plug section of the Engel lead and get the genuine Engel 2-pin socket to suit.
