Nofziger Marine - Your Pacific Dealer
We sell to our customers worldwide and all sales are shipped directly from the Trinidad factory to you, with technical support, parts and service provided by the full resources of both Echo Tec and Nofziger Marine.
ECHOTec manufactures the most rugged and easy to operate watermakers / desalinators or desalination systems for yachts, commercial vessels, offshore installations and for land-based applications such as small communities, hotels and beach houses.
Designed for customer installation and ultra-reliable performance, far from factory trained service centers. The wide product range covers modular AC, DC and belt driven watermakers from 8.4 GPH / 32 LPH to self-contained desalination systems with a production of 14.000 GPD or 53,000 LPD per unit.
More than 4,000 ECHOTec desalination systems operate dependably and cost-effective throughout the world, many of them on continuous duty. Only highest quality components, proven to withstand continuous operation in the harsh marine environment and comply to industry standards including: NEMA, ASTM, API, NSF and BSI are selected for safe operation and extended product life cycle.
ECHOTec Watermakers are globally available directly from the manufacturer and through a fast growing net of factory-trained distributors.
What Sets Us Apart?
Lifelong warranty on stainless steel high pressure pump head and the reverse osmosis pressure vessel. Both are manufactured for Echo Tec and to Echo Tec’s specifications.
Uses a triplex plunger pump for low revolution and pulsation free raw water flow – allows motor to run at a lower rpm, which means it’s quieter too!
Spring loaded pressure regulator for constant working pressure – increases the lifespan of your membrane.
Energy and water consumption conscious? So are we! The post treatment pH buffer re-mineralizes the water so it is not as hard… which means you’ll save hundreds of liters of product water over time when rinsing soap from dishes or hair. It’s also much better for stainless tanks.
No proprietary consumables – Membranes, filters, etc. may be obtained anywhere in the world
DC Watermakers for Yachts
12V, 24V, 36V, 48V, 90/96V, 144V and 180V (Modular)
from 8.5 GPH to 75 GPH/1800 GPD
With the release of the new 12 / 24 Volt Watermaker 200-DML-1, ECHOTec achieved a breakthrough in efficiency for watermakers, utilizing ultra-reliable triplex ceramic plunger pumps.
The ECHOTec. pump is a low revolution (570 RPM) stainless steel version, driven by a highly efficient permanent magnet motor, designed for continuous duty under tropical conditions.
No low reliable and service intensive energy recovery pumps or irreparable electronic circuits that can stall the entire system are used on any ECHOTec yacht watermaker.
These desalination systems are made without "bells and whistles" for live aboard offshore cruising and racing with peace of mind.
As for all other ECHOTec watermakers, only highest quality raw materials that have proven to withstand continuous duty in a harsh marine environment are selected for ultimate reliability and lifetime. Therefore, we fabricate all wetted components including the true regulating pressure valve and all high-pressure fittings from high-grade austenitic stainless steel.
Standard System Features - DC Series
CONVENTIONAL VS ENERGY RECOVERY
All watermakers available for yachts follow the same reverse osmosis principle, where highly pressurized seawater flows along a rolled up, semi permeable membrane, which allows a certain amount of freshwater to pass. This freshwater is collected and directed into the tanks, while the rest of the seawater flows back into the sea as brine.
The main difference is that on ‘energy recovery’ style systems, some of the energy that is still available in the pressurized brine reject water is ‘recovered’ and used to assist in driving the single cylinder high pressure pump.
Energy Recovery Watermakers
Use less-robust small pumps with a complex ‘intensifier’
Price is far higher due to complex nature of the recovery device and any electronic circuits
Single piston pump generates more heat
Draw less power
Make less water
Conventional Echo Tec Watermakers
Use heavy duty pumps and motors – specifically designed for the purpose
Lower cost AND higher reliability
Push large quantities of water at stable high pressure so membrane lifespan is maximized
Draw more power
Make more water
The Irony of Energy Recovery
As cruisers, we strive toward an energy-neutral boat… but we still don’t choose ‘energy-recovery’ watermakers.
Set up your boat with a decent battery bank and charging system – solar panels, a hydrogenerator, a fuel cell… there are many ways to go. The difference in power needs between an Echo Tec and an ‘energy-recovery’ system is a 50W solar panel (20 Amps per day).
Whether you have a DC, AC, or engine-driven Echo Tec system, also take advantage of that extra power during times when you’re motoring, and make lots of water! Chances are you’ll be motoring at least once a week in light air or in and out of anchorages. If you have a generator, you can run a watermaker off that too.
The idea of run it less and make more water – faster, is what drives us to believe that ‘conventional’ is the way to go.
Energy recovery just doesn’t add up: the considerable extra cost, complexity (reduced reliability), and longer running time – which means more heat and noise.
