Seabird Product

Yachty Product

The three 240 volt Dolphin products are shown in the images above and depicts what is included with your purchase.

There is no DV volt version available.

Dolphin Requirements:

• 240 volt operation only.
• Requires a minimum 6kva genset or shore power.
• Cannot be operated from an inverter.
• Diesel engine version available.

The Dolphin range of products marketed by Marine Direct include:

• SEAMAN: This series offers three models - a 30 litre/hr unit, a 60 litre/hr unit and a 110 litre/hr unit.  All are 240 volt only.  The SEAMAN is sold in modular format witht he user mounting the system as required. The SEAMAN is intended for intermittent operation on a pleasure boat only and not intended for continuous use. The SEAMAN are ideal for privately owned yacht and motor boat operations where self reliance for water is required.
  
  The Seaman could be considered the "economy" model of the range, however it is packed with features.  The main differences are its bronze pump and manual operation. (The more expensive Seabird Model has a stainless pump, mounting frame and some automated features.)
  
  With an approximate price of about A$5500 for a 60 litre per hour unit, the SEAMAN is definitely the best value 240 volt desalinator in Australia.  The Seaman can output up to 120 litres per hour with additional membranes.
   
• SEABIRD: The Seabird is available in  60 litre/hr, 110 litre/hr unit and 220 litre/hr configurations. This Seabird is housed in a compact frame as one complete assembled unit. The Seabird also offers a simplified all-in-one desalinator that is an economical and efficient solution to obtaining quality fresh water.  
  
  A newly engineered frame and mounting plates create a tidy appearance while allowing easy access to the systems internal components for regular maintenance. The range has proven successful to date working well in confined spaces.
   
• YACHTY: This series is by far the most popular range of Dolphin Desalinators, and is available with production capacities of 60 litre/hr, 110 litre/hr, 160 litre/hr and 210 litre/hr. These units are available in 240 volt single or 3 phase and are semi-automatic models. Available in either modular or compact format, they are supplied complete with feed pump.
  
  The YACHTY  is a step up from the SEAMAN and SEABIRD models and include flow meters and salinity monitors to check the operation of the unit. It will automatically shut down desalinator when the raw water feed pressure is either too high or too low and will measure the salinity of the permeate water. Start up of the feed pump and the desalinator, fresh water flush / backwashing and cleaning are all still required to be done manually. The option of adding an automatic flush system is available on these models.

OPERATION & MAINTENANCE:

All desalinators, regardless of the brand and the automation level require regular maintenance.  If a desalinator is not maintained, it will:

• Have reduce output
• Have reduce quality and purity of water

• Cease operation and may require the replacement of the expensive membranes.
   

To avoid these problems there are a few basic steps that are required to maintain the desalinator on a boat:
 

These are:

• Reverse fresh water flush using water made by the desalinator.  (You cannot use tap water for this process)

• Cleaning, more commonly known as "pickling" the system.  This involves bypassing the salt raw water intake line and drawing from a solution of purified water and special chemical.
  
   

Regardless of your brand of desalinator, you will have to both flush and "pickle" the system.  If the system is being used continuously while on an extended holiday, you could flush every day or every week.  Pickling should be done weekly, monthly or twice a year depending upon useage.

The longevity of the membranes is "directly related to the flushing and cleaning of the system."
