PALL Water Units

Early in 2005 DMG was approached by PALL, a company specialising in filtration systems, particularly for the military, producing oil and fuel filters for tanks, helicopters, aircraft and ships. They have also started construction of mobile water purification systems for the Army, such as those used recently in Indonesia during the Tsunami crisis.

This new system in made in three modules which are the size of standard 10 x 8 foot ISO containers for ease of transport. PALL wanted us to produce a model which would depict the modules set up and in use. With the modules being open sided we needed to show a lot of detail of the piping, filters and power systems used to drive the filtering system.

We came up with several ideas which were put forward to PALL executives and a decision was made to have the units sitting in a display case diorama showing the water being taken by pump from a dirty creek and passed through the filter system and coming out clean into the storage “Donut” at the other end.

The model was constructed in a scale of 1:16 which gave a suitable size to the model, but not too big to be able to transport overseas as luggage on commercial aircraft. The entire model was constructed from “Evergreen” and “Plastruct” styrene shapes. “Plastruct” has a great range of tubes and fittings, such as valves and elbows suitable for this type of modelling.

The display case was constructed by City West Plastics in Sydney and was not the usual type they do for us. This case had to have a hinged top with a slot fitted into the back of the case to allow photo backgrounds to be slipped in and out. The base was cut to fit inside the case and screwed through the case. This allowed us to landscape the base and work out the best location for the models before being permanently fitted in place. The hinged top allows the modules to be “Unplugged” from each other and removed from the display case to show more of the features of each unit. The roof of each module also detaches to allow more of the detail inside to be seen.

With a photo of our local bushland, enlarged and laminated, slipped into the background, the overall effect is very good, allowing viewers to be part of the set up units in the camp.

The models first showing was in April at a UN conference in Jordan and will be used for many other trade exhibitions in the coming years.
