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. 

High-Pressure Hoses
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.

Flush Timer
Battery-operated timer to time-limit manual flash or automatically repeat flash at the operator’s selected interval and duration.

What Kinds of Boats Need Watermakers for Fishing? 

As one of the most experienced manufacturers of engine-driven watermakers, we have much experience when it comes to boating and the different activities done on them. One of the most popular experiences you could have on boats is fishing. Fishing, like most other hobbies, has many different applications. Perhaps the fishermen that most need watermakers are those on deep-sea and commercial fishing boats. 

Watermakers have become an indispensable asset for a variety of fishing vessels, offering a consistent and reliable source of fresh water, crucial for the needs of the crew and the success of the fishing operation. Long offshore trips and extended stays at sea, common among deep-sea and commercial fishing boats, necessitate a dependable supply of clean water for drinking, cooking, and cleaning. 

In addition, sportfishing and charter boats that cater to anglers on multi-day excursions also find watermakers invaluable, ensuring passengers have access to fresh water and maintaining their comfort throughout the trip. 

Do Watermakers Work in Freshwater? 

Watermakers, in their core function, are designed to make impure or undrinkable water into fresh, potable water by removing salts and impurities through a process known as reverse osmosis. With the proper care, our modular 12V watermakers for sale will provide you with the resources to create ample amounts of drinking water wherever your adventures take you.

How Long Do Watermakers Last? 

The lifespan of a watermaker is a key consideration for any potential user. While the longevity of a watermaker can vary depending on factors like maintenance, usage, and the quality of components, a well-maintained and high-quality watermaker can last for many years. With regular servicing and proper care, a typical watermaker can endure anywhere from 5 to 15 years or even longer. Routine maintenance – such as cleaning filters, flushing the system, and replacing consumable parts – is essential to prolong its life and maintain peak performance. The durability of each watermaker will vary, but with good maintenance, they are sure to last.
