Choosing A Desalinator



	How Much Water Do You Need? The formula is simple, filling in the detail is more difficult. How Much Can A Person Use In A Day? Anything from ten to twenty five litres! The average is about fifty litres per person per day. If you have an automatic dishwasher or clothes washer these count as persons. Engine/Generator Running Time This may be as little as two hours in twenty four, limited to battery charging, food preservation and desalinating so you would need to produce a day's supply of water in two hours. If of course you run longer generator hours for air conditioning then a smaller output desalinator will over a longer time still produce a day's supply. The H20 series with outputs from 36.25 litre/hour to 276 litre/hour, these are fully automatic machines with electronic water quality sensing and automatic divert valves and indication lights displaying plant status. The SH20 series with outputs from 36.25 litre/hour to 276 litre/hour, which are simplified machines which use instead "water taste" and a manual divert tap.		The OCEAN series with outputs from 27.5 litres/hour to 104 litre/hour which are ultra simple machines for use only in ocean water far away from coasts, and are similar in operation to the SH20 . The TON range producing from 10m³ per 24 hours upwards. Please apply to Seafresh for professional advice regarding this product. Drives Machines can be driven by various voltages of AC current and DC current, by belt drive from an engine power take off pulley or be self powered. The standard H20 and SH20can be driven by onboard AC generators of 4kW and have a run load of circa 8 amps at 230V. The LE (Low Energy) model which is available in a limited range of outputs has a run load of circa 5 amps, the LE model produces 15% less product water than the standard models. Most machines consist of four component parts which helps the installation particularly in smaller craft. Components suit a larger number of cases, however, the components can be mounted in a "space frame" sometimes called "A box without sides" this type is usually found in larger vessels and it should be remembered when planning an installation that access is required all round for maintenance.
