INTER SER presents Eolo

With the advent of digital printing, tile temperature during the printing operation has become an  important factor because in order to operate correctly an inkjet machine needs to print on a surface that is not excessively hot. This temperature varies according to the type of digital machine and the ink.

Inter Ser is now proposing a system based on compressed air that solves many of the problems that occur with the most widely used digital machines.

Eolo lowers the temperature of the tile surface by around 5-10°C (depending on working conditions) and completely eliminates water evaporation from the tile at the entrance to the digital machine. The system consists of a cooling machine with low electrical power consumption connected to the compressed air network. The machine transforms the incoming compressed air into cool, dry air at a temperature of 2-4°C and automatically discharges the condensation.

By means of four rows of diffusers, the flow of cool, dry air is directed onto the tile, reducing its surface temperature and most importantly temporarily eliminating evaporation from the surface, allowing the digital machine to operate in optimum conditions.  

This allows for a longer printhead lifetime and reduces cleaning cycles.

Another of Eolo's key strengths is its excellent energy consumption/benefit ratio.
In its standard configuration for applications on 600x600 mm size tiles (equipped with four 750 mm cooling bars set to a pressure of 2.8 bar), the system consumes the equivalent of 8.4 kW. This value is much lower than that of any other cooling system currently on the market. The heavy-duty configuration with six 750 mm cooling bars and a maximum operating pressure of 5 bar consumes the equivalent of 16 kW. This means that Eolo is not only the most cost-effective solution in terms of the initial investment but most importantly it is the solution with the lowest operating costs.

Eolo only operates when needed. It is equipped with an electrical panel that uses a sensor to detect the presence of a tile on the conveyor line and shuts down the airflow when tiles are absent in order to make further energy savings. The cool airflow automatically restarts as soon as required. Eolo is simple to use and highly versatile. It can be installed before any digital machine without the need to make alterations to the line and delivers good results even with a very high line speed (65 pieces per minute).

With more than 100 installations up and running worldwide, Eolo is currently the most widely used and tested machine in the sector.
