Only way to keep our Demonic (Dometic) fridge happy on hot sunny days is to deploy the street-side awning. Otherwise, the fridge control panel says internal temps climb into the low 40's - which makes me unhappy. Definitely interested in a Vitrifrigo once we get our battery situation addressed. Sadly, the battery upgrade is probably a ways off, but at least we have a nice long list of awesome upgrades we want to make.

My Dometic was struggling this past weekend out at Table Rock Lake this past weekend, 96F and high humidity and the trailer as in full sun. Had all my awnings deployed. The Airstream sat in the sun at home prepping for the trip without the A/C on and it was 100F in the trailer. With a thermometer in the fridge is was about 28F at 7:30am but by 5pm it was up to 40. By the time we got to the lake it as about 43F. With the A/C and overnight cooling back down near freezing. With the A/C and the awnings out it kept below 40f. Kept the beer in an ice chest inside the trailer. Still had a fun time swimming, biking and taking a 5 mile walk. Why do I have to come home

Those are respectable temps. Freezer should be around zero or a bit above and fridge around 40. Safe temps for food preservation.

So I went ahead and did the conversion. I ordered the Nova Kool LT201F three plate kit from Binnacle.com. This came with the Secop compressor which is the same as the Danfoss, but newer since Secop bought it out or whatever happened. Still 12v, highly efficient and able to operate on an angle up to 30 degrees, permanently.

What I did was to pull the OEM cooling unit entirely off. The only wires left on the box were for the fridge light. From there I cut a slot in the freezer compartment that was wide and thick enough for the double plate, and the refrigerator cooling fins left a nice big hole in the fridge compartment that was perfect for the single cooling plate in the fridge - just had to notch for the tubes.

I mounted the freezer plate to the back, directly against the metal box, just like the OEM way. This will help the entire freezer box freeze, as OEM.

I mounted the refrigerator plate to the top of the refrigerator box since cold air drops. I may need to figure out a drip tray under it, but that will be simple to do. I left the OEM drain hose and associated pieces as-is just in case.

Some 8" wide aluminum flashing from home depot, and I mounted that with double sided tape to cover the old fin box hole. I caulked with pure silicone front and back.

I used 2" thick 13r foil sided rigid foam board to fill in the approximately 4" deep cavity left by the old cooling unit. This stuff cuts like butter with a Japanese pull saw!

We are very happy to have gone this route. I think I saved at least 50-60 pounds as well. That old evaporative cooling unit is heavy. I cannot believe those are apparently cheaper to make than an efficient compressor.

Pictures showing the progression below. I had to run to the airport as soon as I got it turned on and verified, so I'll get pictures of the compressor too later next week. I also created a custom 'cap' to the propane out of some hardware copper. I also closed up the fridge vent since that is no longer required with this setup.

Brilliant conversion. I am surprised more people or pro RV fridge techs do not do this. Looking forward to your follow up report and photos.

Is there a new control panel that comes with the kit. Is it mounted inside the fridge and the external Dometic control panel is now not used?

A traditional control panel is no longer used.
Good reading here,

Here are a couple pictures showing the compressor and how I capped the propane. I ran the unit at setting 7, out of 7, since I left on Saturday and it started to freeze the refrigerator, so thats great. I put it on 3 overnight and that seems to be the ideal. I rarely hear the compressor running.

So far, so good - we are going on a 3-day trip this weekend and will not have hookups, and will likely use the furnace at night. I will have generator for daily recharging though. I'll let the group know how we fare!

I think you will be pleasantly surprised how little you need to recharge the batteries - at least for the fridge

No battery issues with our last trip. Usage was typical for that area, with cold nights requiring the heater at night. Fridge kept properly cold, and we are happy with the decision!

Love this project. I'm probably not brave enough to make the conversion, but this also argues well for swapping out the Demonic fridge for a Vitrifrigo or other danfoss-based fridge. Thanks!

You will find that the Vitrifrigo DP-2600i (available own both black finish and stainless) will be almost the perfect fit for the Dometic unit that comes with a 27. A 3/4" spacer on one vertical side and a 1"+ shim at the top and it's a prefect fit! Quick and easy.

Just did another one today! Stainless (Inox) version...........

Sorry, shot went horizontal on me. Perhaps one of the Mods can straighten it out. It still has the plastic wrap on the stainless doors.

Nice, thanks! Can't wait, but have to wait...until we do the big Lithium / Solar upgrade on Rocinante in a year or two so we have sufficient amp hours. Until then, we'll keep feeding the demon behind our fridge , bribing him with propane and electricity to keep the food cold.

Lewster - or anyone else who has worked with the Vitrifrigo. . .

I am looking at the DP150IBD4-S model from Vitrifrigo as its dimensions are nearly identical to the Dometic RM2551 from what Iíve been able to research.

The low resolution pictures of the Vitrifrigo I see on the web make it appear that there isnít a trim piece along the bottom of the unit. Looks like there are a couple of metal rails that the unit sits on. With an LP gas refrigerator, I can certainly see why there is a need for no air penetration from the rear compartment area into the living quarters. With an all electric refrigerator, this seems irrelevant ó but gotta make sure that LP gas line is capped good and not leaking.

Can anyone confirm if my observations are correct? Will there be a bit of an exposed gap at the bottom of the refrigerator giving access for ants and other critters to get into the living space? Thatís where my concern lies more so than cosmetics.

I have wire screen across the two vent doors presently which is good enough to prevent mud daubers from causing problems. But the holes in the screen would not prevent ants or small roaches from entering. With a Vitrifrigo, I assume the vent doors can be more thoroughly (but not permanently) sealed.

Thanks for any thoughts/observations on this.
