Great bit of kit

Posted by Rob (Weston Marine Life) on 3rd Jul 2011

We got our Merlin RO System back in April from Osmotics. After some good advice from they guys at Osmotics, we chose the Merlin, it's an easy bit of kit to use and not much biger than a normal 6 stage RO unit. Up and running in a few mins with very good water production from mains pressure. No Booster pump is needed (for most).

Just a few small points with these.

Make sure you get a 1/2" tap connector to go with this - ie: John Guest 1/2" BSP Tap Connector for 1/2" Tube or John Guest 3/4" BSP Tap Connector for 1/2" Tube otherwise you will scratch your head trying to connect to your mains feed.

I have also opted to put an extra 2x20" filters before the Merlin with a 5 micron pre-filter and a carbon gran (note Merlin has a 20" carbon block filter already). I am considdering putting a third 20" filter on for Softener Resin at the start.

We also put another 2x 20" filters after for DI resin.

Apart from me fiddling the unit has worked really well and would recommend these to anyone.

We can easily fill our 1000ltr IBC in under a day, even in winter. Our 2 old triple 150gpd membrane units (max in theory of 900gpd) with boosters would take 2-3 days before.

The flow rates will suprise you if you are only used to smaller RO units.
