High-Pressure Pump Head
Corrosion-resistant Stainless steel AISI 316 pump head, ceramic pistons, and stainless valves versus Nickel plated brass head, ceramic pistons, and stainless valves. Increase warranty on pump head from 2 years to 5 years.

High-Pressure Pump (Low Noise Pump Upgrade)
Extremely silent pump design. Quietest pump on the market.
Only available in combination with the AISI 316 stainless steel pump head upgrade.
This pump comes with a lifelong warranty.

High-Pressure Hoses 
Standard: 2 pcs 5’ / 1.5m fixed length hoses (can be ordered in lengths to fit your installation) with AISI 316 compression fittings.
Upgrade: 15’ / 4.5m high-pressure hose with field attachable AISI 316 O-ring sealed fittings.

Fittings and Regulator
DUPLEX 1.4462 (similar to 2205) is more costly and 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 AML Series watermakers and is available as an option for the Economy Series.
The Duplex package comes with a lifetime warranty.

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 have 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).

Electrical Control Unit
Low voltage automatic breakers actuate waterproof enclosed heavy-duty 24 VAC double pole motor starters for feed pump and high-pressure pump. Prewired and ready to connect.

High-Pressure Gauge
Upgrade: All AISI 316 stainless steel with Monel bourdon tube
Standard: Plated brass connection with AISI 304 case 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.

Manual Product Diverter Valve
3-Way valve to switch from dumping (the first high salinity product) to fill 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.

Feed Pump, Centrifugal / Feed Pump, Diaphragm
While the magnetic drive seal-less centrifugal pump is more costly, it does not deplete as much as diaphragm pumps.
The centrifugal pump is recommended as it provides constant feed flow, without building unnecessary pressure that results in excessive power consumption and wear. A diaphragm pump is a positive displacement pump that will be feeding another positive displacement pump.
Cheaper but not a good combination.

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 storing 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.

How Do You Turn Salt Water Into Fresh Water on a Boat? 

No matter what kind of boat you are using or the kind of boating that you look to do, you are going to need fresh water. 

When you are navigating the high seas, we understand the indispensable need for a consistent supply of fresh water on boats. Desalination machines, without a doubt, emerge as the ultimate solution for transforming saltwater into fresh water right onboard. These machines work to give boaters convenient access to potable water. 

With an AC desalination system like the one offered by ECHOTec, you can power your desalination systems with the assistance of a generator. 

How Big of a Watermaker Do I Need? 

Selecting the right watermaker size is a critical decision for those seeking a reliable source of fresh water, whether it’s for marine, remote locations (where you will need home desalination machines), or even emergency situations. The first step is to consider your water consumption needs. A smaller watermaker is a suitable choice when space and energy constraints exist or when freshwater demands are minimal. Compact watermakers are particularly effective on smaller boats, where size and power are often at a premium.

Nevertheless, for those facing more substantial water demands or operating in remote, water-scarce regions, larger desalination units become the clear choice. Larger systems are capable of producing higher volumes of fresh water and are designed for more demanding conditions.

Are AC Systems the Best Watermakers for Small Boats?

When it comes to outfitting small boats with a watermaker, the choice between AC (alternating current) systems and other options largely depends on the specific needs and constraints of your vessel. AC systems can be a great choice for smaller boats with readily available shore power or onboard generators. On the other hand, engine-driven watermakers are best suited for boats that do not have readily available on-shore power. Small boats are generally not going to be out at sea too often, which means that they will have ample opportunity to use on-shore power to power their 12-volt marine water makers. 

Are You Interested in Small Marine Watermakers for Sale? ECHOTec is Here to Help!
