Waeco/Dometic Coolmatic CD30 drawer fridge

I’m installing a kitchen under the bed. A CD30 drawer fridge is perfect for this. It’s only 25cm high but holds 30 liters. Downside off course is the fact that you can’t store taller items standing up.

Energy efficiency

It’s a compressor fridge and energy efficient. The manual claims it uses 40 watts but some testing shows it only uses 2.2 amps @ 13,9V (about 30 watts) when the compressor and cooling fan are running with a small spike to 3 amps when the compressor kicks in. The requested temperature and the ambient temperature will determine how often the compressor and fan will run. The 110 watts solar panel and 110Ah AGM battery should provide enough power to run the fridge for 24 hours.

Ventilation and insulation

The unit doesn’t make much noise and most of it is coming from the fan. Considering the fridge will be under the bed, I expect it will be muffled to enough to not be a nuisance during the night. The ventilation is following a kind of “maze”. This will probably help with keeping the noise down. The fan will take air at floor level behind the water tanks. The warm air will be expelled underneath the sink.

    Is it difficult to move the compressor to the side of the unit?

      Hi Dave, the compressor and electronics are mounted on a tray which you can unbolt from the back. The copper pipes between the compressor and the drawer are flexible but would require you to bend them carefully.That would be a but scary. Both the pipe and the wiring are long enough to relocate the tray. Mounting the tray to a wall would be the most convenient way to secure the compressor. The Waeco is designed to offer this flexibility. You can check the manual using the link in the article. Please let me know if you successfully moved the compressor. I will keep it in the stock location.
