Choosing the right marine system
If you've visited our Buy Now page you might have been overwhelmed by the number of systems we have on offer so let's break it down to help you with your decision. Don't forget we are only an email or phone call away so don't hesitate to reach out and we'll ensure you don't spend more than you need.
First Decision - How many litres per hour?
There are a number of items to take into account here:
How long do I run my genset each day?
How many people do I have on board?
How large is my water tank?
All of these impact upon whether you need an 80 litre per hour solution, a 160 or a 240. If you only wish to run the genset for the shortest time possible you may wish to consider a 160 or 240 litre (per hour) solution. The pumps use a similar amount of power to run per hour regardless of litres produced. If you run your genset for more than 1-2 hours per day an 80 system may suffice. An average person uses 60 litres per day on a boat. This obviously can fluctuate if you have family that love washing their hair or shower often. The goal is to replenish whatever size tank you have each day or two with the water used. So, if you have 4 people on board you may use 240 litres in a day. Our 80 system will need to run for 3 hours, our 160 system for 1.5 and our 240 litre per hour system for only an hour. p.s Our most popular systems are the 160 litres per hour ones.
Second Decision - Which high-pressure pump?
* Basic Karcher K2 pump?
* Karcher K5 water-cooled pump?
* Premium Italian Ceramic Piston Stainless Valve Triplex pump?
The K2 is supplied with our lowest price solutions and happily runs an 80 system. It's designed to last for only a few years but is covered by our initial 24 month warranty. If it fails after those 2 years it's only $99 to replace so it will take you 30-40 years to spend the same money on the K2 as you would have spent on the Italian Triplex one. Our automated fresh water flush that comes with every system also helps the Karchers last longer as well as protecting the expensive RO membrane. Other companies charge over $500 for a similar 'add-on'. It's essential. The K2 is only suitable for spaces away from the hot engine room. The K5 Compact is the affordable workhorse of our solutions. It's water-cooled (so great for those hot spaces) and this also reduces the pump noise. It's powerful enough to happily power the 80 and 160 systems. Once again, if you replace this pump every 3 years you will take 15 years before you have spent the same amount as the Italian Triplex pump. Speaking of the Italian Triplex pump - the flagship of our fleet! Stainless steel valves. Ceramic pistons. IP56 rated motor (protected from water spray). If you are looking for many years of zero worries - this is the one for you and the best pump for all our systems - 80, 160 and 240.
Third Decision - What Voltage - 12v or 240v?
* 12v system?
* 240v system?
All of our high pressure pumps are 240v. We've considered 12v motors and have not selected them for two reasons - 1) they are very expensive and 2) they must be located next to the batteries thus limiting where you install the system. For this reason our 12v total systems come with a 12v boost pump and an inverter for the 240v high pressure pump. That way the inverter can be located next to the batteries and a 240v cable can be run to any part of the boat where you have chosen to place the pump. Each litre of water required the same amount of energy to produce whether you use 12, 24, 110 or 240v so it makes no difference. Our systems will also run using a Honda 2.2i small generator. Most of our clients choose a 240v system. It's your decision. Please note that the K2 will only run a 12v 80 litres per hour system whilst the Premium pump will run all systems on 12v.
Forth Decision - Remote Panel?
We have developed a remote control panel that measures 300mm x 300mm that will bring together all the switches, gauges, meters and controls to a central location. This allows you to have a stylish panel to run the system without having to open a hatch or having to enter a lazarette to turn the system on and off. They come in 3 colours - black, white or timber grain. Of course the systems work perfectly without this option.
Please note that each panel comes with an extra high-pressure hose to join the membranes with the panel. We will need to know the length of that hose in metres. The panel comes fully assembled.
Fifth Decision - Where will I put it?
That requires consideration but all of our systems are modular and connected by John Guest PEX hoses. This means that you can place the boost pump near the seacock - you can place the pre-filters anywhere convenient and run hose to them and you can place the high pressure pump and tubes also wherever you find best. We sometimes think that we have made it too difficult for our clients as they have too many options! Seriously though, we have yet to find a boat where our solutions just couldn't be squeezed in.
Some dimensions for you of the major items (approximate):
* High Pressure Tube - 1500x200x200 (mm) required (we can get it down to 1200 with 90 degree end fittings - just specifiy in the note of your purchase)
* High Pressure Pumps - 600x400x400
* Filter Assembly - 1000x400x200 (you can separate it as required)
Once again, we are only a phone call or email away to assist you with your decision. We want to ensure you pick the best solution for your needs and don't spend any more than you have to on your boating lifestyle.
