FogScreen Holographic Illusion display
We had great fun learning all about this unique product whilst installing one into The South Florida Science Museum and Aquarium. It was a delight seeing the audience reaction to the technology. The unit creates a thin film of practically invisible water vapour that has enough physical presence to allow a projected image to resolve on its surface. The result is a cool Holographic style image that you can walk through.

Planning an Effective FogScreen solution.
Making an effective FogScreen install involves several critical steps.
Firstly and most importantly; select the right manufacturer of the vapor generating equipment. Choose the wrong one and you can end up with an unreliable and only partially effective solution. The unit must generate vapour of very small agglomeration. Do this right and then direct the stream of near invisible water particles so they fall between well balanced retaining air curtains and you are well on the way to an amazing install.
Understand the water supply. Pay attention to this; as it is a potential public health issue if you do this without consideration. You need a microbiologically pure source of water that is treated to ensure that supply does not cause calcium build up. Whilst the water vapour in a properly set up unit from a reliable source has been proved to be incapable of transporting a microbial load like for example legionnaires you still do not want to have a reservoir of untreated water in a public space. Hence the need for this paragraph and the establishment in your mind that you do need to be planning the install with a professional and experienced supplier. Surprisingly a well balanced and properly set up unit hardly produces any water condensate on the floor and these units can; counter to intuition be set up without fear of general public slipping on water condensed on the floor. it just does not work that way but as stated this is kind of counter intuitive until you understand that a properly manufactured unit produces only a very small amount of mass in vapour form and yet is optically very active.
Now you just need to install the unit square flat to ensure good operation. This will also entail ensuring the units 180kg weight can be secured safely above head height.
And of course you will need to have understood the projector set up relative to the vapour screen, including the angle of projection the brightness of the projector and the lens selection all being planned to work in the light levels of the audience.
Finally you will need to have great content to show of the system capabilities. We found that wire diagrams looked amazing compared to photos or full frame videos. We can help you with what works best on these systems.
We would be delighted to help you navigate these issues and deliver an amazing experience for your audience. Simply call us on 0044 1234 241021

Optimal installation conditions
Electrical Requirements
FogScreenprojection screen runs on 110V and a 15 amp circuit. There is only a single electrical connection required – and it is recommended to have an Edison input or adapter on hand.
Water Requirements
FogScreenprojection screen can draw water from a water tank or from a pressurized water line. It only requires 6 to 10 liters per hour of regular tap water with normal settings. In permanent installations it is advisable to add a reverse osmosis filter to take some of the mineral content out of the water, as this will reduce the maintenance cycle. Permanent installations will always be fixed to a pressurized waterline to ensure a continual water source. The screen is self-regulating and the magnetic valve will open whenever new water is required. It is recommended to use a water softener and possibly other means to filter the water before use if the water quality is low. There are two options for temporary events:
1.) Pressurized water line: Ensure that the venue has available plumbing. In tradeshows, this can normally be ordered to the booth. The connector will need to attach to a 6.5 mm (1/4”) fitting.
2.) Water tank: FogScreen projection screen ships in two cases – the screen case, and a smaller Peli-case that contains the CU, hoses, cables, pump and chain lifters. Once the screen is set up, the Peli-case is empty and can be used to store water. This case will store about 120 - 130 liters of water – enough to last about 2 days of 8 hour use. The case can be set on the ground up to 10 m away from the FogScreenTM. The case dimensions are 0.8 m wide x 0.5 m tall x 0.6 m deep.
Floor Requirements
The fog generated by FogScreen projection screen is perfectly dry because of the small particle size. However, FogScreen projection screen is a water-based display so there will be some condensation drops that build up in the generator that will fall to the floor below the screen. Under normal operating conditions this is not more than 1 or 2 drops per minute. It does not create a significant water problem on the floor, but any amount of water can lead to a slip hazard. For installations over hard surfaces (tile, wood, concrete etc…), an absorbent or tufted mat is recommended. The mat size should be approximately 2.3 m x 1 m to catch all the condensation. Over the course of a regular operating day, the mat will get damp to the touch, but will dry before the next use the following day.
