Fcubed solar water distiller

April 13, 2019 — BarryK

About five years ago, I mentioned to my daughter how cool these are, then, darn, she went and bought me one. For my birthday. Cool it is, but I did not have a circumstance to use it, so it has been in the shed ever since.

The manufacturer is F-Cubed, and here is their website:

In a nutshell, they manufacture a solar-powered water distiller:


They don't seem to make mine anymore. Mine is about 1.1 x 1.1 metres, very short. Much less efficient than the full-length ones. I can't find the water-output specs, but I do recall it is considerably less.

Fast forward to now, I have got it out of the shed and assembled it. There is now a potential use, for when I "go bush" for extended periods, where there is brakish/salty water available. Here it is:


The plan is to mount L-brackets to slide it under my car roof-rack. At the remote site, slide it out, attach the legs, and the water supply.

Curiously, the desalinator is made of aluminium and plastic, the legs of steel -- and the legs weigh as much as the desalinator. So, might just cut some marine ply for each side, something simple to sit it at the right angle.

An overhead water supply is required, but it will also handle pumped water. So, I could just bring brakish/salty water in a bucket, put a 12v pump into it. It would need a filter. Anyone reading this have experience, can recommend a product? Pumps used in fish tanks?

Ah ha, the F-Cubed Malaysian website mentions my panel, it is the "Carocell 1000", with these specs:

Temperature 20°C 5 Litres / DAY
Temperature 30°C 7 Litres / DAY
Dimensions: 1150 x 1150mm x 50mm
Surface Area: 1m2
Weight: 7kg

So, on a hot summer day here in AU, I should expect more than 7 litres. That's good. But, how much water would I have to put in?

I have decided against pumping, gravity feed is good enough, can easily put a water tank on the roof-rack of the car. Bunnings has a cheap 20 litre collapsible water holder. And, as 'scsijon' pointed out in an email, plywood sides is probably not a good idea, as it would restrict air flow -- so will rethink that.

My website now has a "nomad" section, and a webpage where I plan to document the water desalination project as it progresses:
