Circular water printer for rent
Other names: Circular Digital Water Curtain, Round Interactive Water Wall, Round Water Display, Curved Digital Waterfall, Round Graphical Waterfall
How does the machine work?
The water printer consists of a water tank and a frame made of an aluminium stage truss.
A water printer with a large number of nozzles is built into the upper beam of the frame. Water flow through the nozzles is electronically controlled. The drops formed this way create falling images.
Water circulates in a closed system. It falls into the tank below. Then, it is filtered and pumped back up.
The tank is enclosed in stainless steel plates. The vertical plates are additionally covered with black or white adhesive foil.
The frame is covered with aesthetic sleeves made of white or black lycra
What can be displayed?
The water printer can print any graphics, logos or texts prepared in black and white graphic files. Shades of grey cannot be displayed.

The complete machine is at least 1.4m wider and longer than the diameter of the water circle
It allows viewers to draw any black and white images with their fingers in the android application.
After pressing the start button, the water printer immediately stops printing the default program to display the shapes drawn by the viewer three times. Then the machine returns to printing the default program.
Data transmission via bluetooth with a range of about 15m.
The client can place it on a stand or hand it to service personnel.
Installation site requirements
The best water visibility is obtained against a dark background.
Under normal conditions, the falling water will not spray out of the tank noticeably. However, it cannot be ruled out that water will wet the floor as a result of: wind, viewers touching streams of water, during assembly and disassembly.
The machine is rainproof but it cannot work during a storm.
Winds over 7 knots (3 on the Beaufort scale) can deform falling images and cause water to fall outside the tank or wet people nearby. To reduce the risk of wind it is worth to: place the water printer in front of a wall or artificial background, protected against the wind, put the machine sideways to the wind, not to place the machine in constrictions, e.g. between buildings, where the wind increases.
Flat, even surface, free of holes and sharp elements.
Ground inclination not greater than 2.5 degrees. The measurement can be made using a mobile phone. Download a sample Android application

Enclosure and branding
The vertical walls of the water printer's tank can be stuck with self-adhesive foil. The service of printing such foil is priced individually.
The customer can enclose the structure of aluminium trusses according to their own requirements. The assembly method using the assembly elements supplied by us is shown in the technical drawings.
The water tank has no load-bearing properties. The enclosure provided by the customer should not be based on it.
Water is poured only once during machine installation. However, in windy weather it may be necessary to top up the water during a several-day show.
Amount of water in the system: <250 liters for each square meter of floor surface occupied by the machine.
Water availability on installation day - Fire hydrant/fire hose, tap for connecting a garden hose at a distance of less than 50m.
