DIMENSIONS
The below table provides the length, width, height, and weight of the various reverse osmosis desalination modules. The listed dimensions represent the greatest size measurement to create a box that the module can be contained within. However, as can be seen in the module photo images, the desalination machines for boats modules could actually fit into a smaller space depending upon the installation orientation. These dimensions do not include the room needed for wires or hoses to enter or exit the equipment. All equipment comes with straight fittings. Optional 90-degree fittings are available.

* Please notify us if you plan a 220VAC installation so we can change the standard 120VAC electrical switch for the high-pressure pump motor in your remote panel.
*Please notify us if you plan a 24VDC installation so we can change the standard 12VDC electrical switch for your boost pump in your remote panel.
* Standard Boost pump is a 12VDC self-priming pump.
(Here is a link to a Video we made explaining why we like the 12V DC pump)
* A 120VAC Boost pump option available using 1.5Amp $200 Adder
* A 24VDC Boost pump is available using 6.5Amp $200 Adder
NOT PROVIDED
