Build your modular watermaker to your preferences.
ECHOTec Economy Watermakers come with everything you need to install onboard and produce freshwater from the sea.
If the high-pressure pump will be installed less than 40cm below the waterline, an optional seawater feed pump will be required.
Customize to your preferences with the options and upgrades in the below table.
The workhorse DML Yacht Series is entered for specification and cost comparison and as a benchmark for ultimate performance and reliability.

Optional Equipment and Upgrades
Fittings and Regulator
DUPLEX 1.4462 (similar to 2205) is more costly and more difficult to form and machine but achieves almost twice the corrosion resistance of AISI 316 stainless steel.
DUPLEX has been successfully used for all high-pressure fittings and pressure regulators of ECHOTec commercial desalination systems for the past 10 years. The Duplex package comes now with all DML Series watermakers and is available as an option for the Economy Series. The Duplex package comes with a lifetime warranty (If for any reason, a DUPLEX regulator or fitting ever fails, we replace it. Period).
High-Pressure Pump Head
Corrosion-resistant Stainless steel AISI 316 head, ceramic pistons, and stainless valves versus Nickel plated head, ceramic pistons, and stainless valves.
High-Pressure Pump (Low Noise Pump Upgrade)
Extremely silent operation. Quietest pump on the market.
Only available in combination with the AISI 316 stainless steel pump head upgrade.
Upgrade from2 pcs 5’ / 1.5m fixed length hoses (can be ordered to your length requirement) with AISI 316 compression fittings to 15’ / 4.5m high-pressure hose with field attachable AISI 316 O-ring sealed fittings.
Pump Motor Epoxy Sealed
Completely sealed and Epoxy plus Polyurethane coated wash-down motor versus standard motor.
Anti-Vibration Pump Mount
Anti-vibration motor/pump unit mount with specially engineered soft vibration dampers.
This feature dramatically reduces noise transfer into the hull.
Membrane Vessel Assembly
DUPLEX 1.4462 versus AISI 316 vessel components come with a lifelong warranty on the complete membrane vessel.
Filter Brackets 3pcs.
Extremely rigid brackets from AISI 316 versus painted standard brackets from aluminum.
Remote Control Panel
AISI 316 stainless steel control panel for remote operation (completely assembled).
1500 PSI Gauge
All AISI 316 stainless steel with Monel bourdon tube versus a plated Brass connection with AISI 304 dial and AISI 316 bourdon tube.
Braided Hose / AISI 316 hose clamps
40’ braided hose with 29 pcs AISI 316 hose clamps versus 15” Polypropylene tubing.
Feed Pump, Centrifugal / Feed Pump, Diaphragm
While the magnetic drive, seal-less centrifugal pump is more costly, it does not wear as much as diaphragm pumps.
Especially for DC systems, a centrifugal pump is recommended as it provides constant feed flow without building unnecessary pressure, resulting in unnecessary power consumption. A diaphragm pump is a positive displacement pump that will be feeding another positive displacement pump. Cheaper but not a good combination.
Manual Product Diverter Valve
Switch from dumping the first high-salinity product to filling the tank with potable product water.
Complete with AISI 316 mounting bracket.
Cleaning/Storage 3-Way Valve
Allows infusion of cleaning and storage solutions with the flick of a valve.
Complete with AISI 316 mounting bracket.
Hardener / pH neutralizer
Kit with mineral element and 2 pcs 3/8” compression fittings, stainless steel bracket with screws
Filter Condition Gauge AISI 316L / AISI 303
The low-pressure gauge indicates when the pre-filters have to be changed or the through-hull becomes clogged (barnacles etc.).
Low-pressure gauge (AISI 316 dial / Monel bourdon tube) -30 +60PSI, ¼” NPT threads direct into the 20-micron filter housing, AISI 316 filter bracket with cutout for gauge.
Low-pressure gauge (AISI 304 housing / AISI 316 bourdon tube) -30 +60PSI, ¼” NPT threads direct into the 20-micron filter housing.
TDS Meter, Real-Time
Fixed installed, indicates the product quality in real-time.
Freshwater Flush Kit
The freshwater flush kit enables storage of the watermaker for up to 10 days without the use of chemicals (biocide).
The freshwater flush storage can be repeated every 10 days.
Flash Kit (Valve) contains 1 Filter housing, 1 active carbon cartridge, Bracket (AISI 316SS), 8 screws, 1 shut-off valve, 2 hose barb connectors, 1 Nylon nipple, 1 Nylon tee, 10 ft. braided hose, 5 hose clamps (AISI 316SS).
Flush Kit (Basic) contains 1 Filter housing, a Non-return valve, 1 active carbon cartridge, an Aluminum bracket, and 2 tube connectors.
Battery-operated timer to time-limit manual flash or automatically repeat flash at the operator’s selected interval and duration.
