need a freezer - and only a freezer!

My Everkool Glacier has two compartments and both can freeze
edit All Glaciers are Fidge or freezers

I have an Engel 45MT which operates in three modes; as an all fridge, as a fridge/freezer (with separator in place) or as an all freezer. It works a treat in all modes.

Paul you'll find that most if not all brands of compressor fridges have freezing capabilities so it can be used either way you like. look at the single compartment ones just crank it up and use it as a freezer only to suit your needs. You'll find lots of people do the similar thing they will have 2 fridges one they use just for freezing goods
Alternatively you can also look at dual compartment fridges in other brands like primus etc etc so you can have 2 smaller freezer compartments and turn one side off to reduce power consumption if your not carrying much. There are so many options out there these days and so many brands that are just as good as Engel which are a lot cheaper.
My 2004 model Evakool is a fridge/freezer remove the centre divider and it becomes a whole fridge or freezer depending what I want to use it for it can freeze down to -23c

One important thing to remember is when used as a freezer most of them just keep running depending on the ambient conditions so they will use a lot of power no matter what brand you buy. Make sure your vehicle is capable of being able to supply enough power for overnight stops if required.

A freezer is an insulated box with insulated lid, compressor/condenser, evaporator and thermostat. Not much to it.

13 years ago I built a deep freeze for the OKA. It uses a Danfoss BD35 remote compressor and has 150mm of closed cell polyurethane foam, so its power consumption is minimal.
The gas lines are QC to the evaporator, and the flat plate evaporator can be bent to whatever shape you want, so it is an easy thing to build.
Works a treat.

Check out the Engel website. They have a 95L upright freezer only that might suit you.



Seems a bit heavy at 35kg, but holds a lot of Chiko Rolls & Dim Sims. Power draw up to 4.8amps.

We have an 80L Engel upright fridge and are really pleased with it. Uses about the same power as a 40L fridge and only weighs 5kg more.

hi
Manufacture anybody can do , you just cannot pressure test commission repair etc . Its is only a mechanical situation prior to commissioning .
Industry has been doing that way for years .
A restricted electrical is fine .

Just about any 12v compressor fridge will work as a freezer. It will be in the specs Most go down to -18 degrees but good ones such as National Luna will go down to -22 or even -24 but they are expensive as hell.

You don't have to make your own there are dozens of off the shelf units for $700 to $3000.

You should consider 2 things.

1)Make sure you get a good one with good insulation.Check the freezer current draw at 30 degrees. That rules out Engel and the cheaper Waecos which have lousy insulation ( Flame suit on).

2)No matter which one you get, a fridge being used as a freezer will draw about 3 times as much current as it will as a fridge. That means a 100 AH battery will last around 12 hours before being flat ( ie 50% of capacity).

To run a freezer for 24 hours you will need at least 200 AH of battery. If you want to camp up longer than that you will also need about 400 W of solar.

You should turn the freezer to its coldest setting when driving then back to about -10 when stopped to maximise your battery life. It gives you a few extra hours per day.

For a freezer that has quality, thick insulation and has a really good life expectancy the Trailblaza Australian made fridge is really good. I have had mine for 22 years without any hiccups.

We use one of the older style Engel car fridges as a freezer. At a lower setting we can use it as an extra fridge instead, depending on our needs at the time.

Hi Paul.Recently I asked Margaret from norcoast refrigeration (makers of trailblazer fridges) to make me a dedicated freezer . I already had two of her fridge freezers. So I was still able to use the unit as a fridge we included two thermostats .Freezer thermostat is set between -16 and minus 6. Its just a matter of selecting which thermostat you want to use. Unit has checker plate aluminuim build ,75mm insulation,bd50 compressor and holds 75 litres. On a recent trip to Broome in temperature's often over 37 degrees(how hot inside the canopy) the unit used around 60 amps per day .I have a watt meter in line that records amps in and out. There were people there using engels and waecos that would not stop running .Cost was $2300 which is good value because going by past experience the unit will outlive me . In cool weather for example last week camping down south the unit only started once during the night.
