  • Fresh water flush
    This is used to flush the plant with potable water when it is being used intermittently, keeping the system fresh for up to eight weeks without the need to preserve it. Any contaminants are removed, ensuring the maximum extension of membrane life.
  • Active carbon filters
    Removes dissolved gases (including chlorine), tastes and odours to improve the taste of the product water. This unit uses the same housing as the pre-filtration cartridges for compatibility and ease of replacement.
  • Air trap
    Separates air from sea water in the sea inlets, ensuring a constant flow to the desalinator pump. This avoids the damaging effects of water starvation on the equipment, particularly on craft with high speed hulls running on air/water emulsion.
  • Spares Kit
    The Standard Spares Kit includes pre-filter elements, plus a range of replacement consumable items including oil for the high pressure pump, various seals, disinfectant and preservative powder, plus a service kit for the primer pump. An Extended 2 Years Spares Kit is also available including all of the above, pluss a comprehensive range of electrical spares and items for mechanical servicing.
  • Heat Exchanger/Preheater
    A pre-heater is required when the sea water intake temperature is below 8 degrees Centigrade to ensure efficient running of the RO plant and avoid damage to the membranes. Various types are available, the most common being a heat exchanger utilising waste heat from the engines. The other main type involves an element which heats the feed water directly.
  • Ultraviolet Steriliser
    The unit sterilises the water to be completely free from bacteria, parasites and algae spores. This can be used as a pre-treatment when operating in dirty waters and as a post treatment if the water has been held in storage for long periods of time.
  • Feed Pumps
    The feed pump delivers water to the pre-filters which have elements of 50 microns and 5 microns before it passes to the high pressure pumps. A choice of models is available which can be run for AC or DC power supplies.
  • High Pressure Pumps
    These pumps operate at pressures of up to 800 psi and are designed to force the seawater through the reverse osmosis membranes where salt and other impurities are removed. Built for long lasting reliability, the pumps have triple plungers, a nickel aluminium bronze pump head and an oil bath crankshaft in an alloy crankcase. They are available in close coupled or belt driven types from a variety of input voltages
