Hi Monte. I met these guys through a friend who bought a distributed system from them. ie. One that can have the components spread out around the boat as apposed to a self contained unit.
I noticed that the translation in the English
manual was a bit confusing, so I offered to help with that. I also chatted at length with the owner and designer
of the systems and we swapped some ideas regarding some new plastics that would eliminate some of the 'O' rings in the Clark/Schenker energy recovery pump.
I have since installed 3 more of them.
wise competitive provided you have cheap delivery
Accurate energy use as advertised provided decent wire section is used, salinity and temperature of feed water are not way out of normal.
I like the auto shut-down, that feeds product water from the boats pressurized fresh water system.
I like the variable speed motor
with soft start.
The quality of everything is superb, but of course the filters and housings etc are all pretty standard as they are buy-ins.
The kit comes with clear instructions, ample tubing (there will be left overs) and nothing is missing.
Charcoal filter is provided standard for flush circuit.
The vane pump comes with a spare head
included in the price.
Less 'O' rings than the competition in their patented pump that gets away with less moving parts
in high wear areas.
I also like the accumulator that smooths out the whole system so it makes less of a clunk sound as the pistons change direction.
"Standard" 80mm membranes (IE other mfgrs will fit)
The vane pump MUST be installed well beneath the waterline for priming. It WILL cavitate if installed at WL. It can be prevented by providing a feed-pump but that will defeat the energy savings somewhat.
Vane pump will fail terminally if run dry for any short period.
pre-filter is not enough for dirty waters, and if you add an extra one there is a production drop. I modified one of the systems to have an extra 30 mic prefilter after the pump with a bypass circuit, so you can use it in bad water, or bypass it for normal use.
has a lot to do with how well it works and how long it remains trouble free. I always put the electrical
parts of the system in a dry area, even if it means drilling a bulkhead to lead the cables
The necessity of having the vane pump located as low as possible makes it vulnerable to flooding damage. It is a permanent magnet motor
, and will affect a fluxgate compass
etc. I mounted 2 of pumps on rubber mounts for less noise transmission
but those boats had a cabin
inches away from the engine
If I was to buy a watermaker
it would be this one.
All of the installations I did were tank-full on solar panels
only for 3 hours of mid-day sun almost daily.
The Euro: Dollar is favorable at the moment, so their smallest unit comes in at just over $3000.00 for 25 l an hour (about 7 gal/h)
Shoo, did not intend to type so much, hope it helped.
