Adiabatic humidification system applied to a manufactory producing aluminium packaging
To prove the remarkable flexibility of the humiFog system, we illustrate an application realised for Tsimis Printing, a well-known Greek company headquartered one hour drive from Athens, which produces coloured quality packaging (for cosmetics, frozen food, ice creams, snacks etc.) made of aluminium foil for provision products.
The company has always been a pioneer in its particular business segment and was among others the first Greek company to introduce the ISO9002 quality standard several years ago.
The rollers of the printing machinery are working at high temperature to obtain correct treatment of the aluminium which causes a high heat emission in the production area. Consequently, the temperatures reach 40 °C in the summer period causing inadequate working conditions.
This problem is of course increased because of the outside summer temperature that can reach up to 45 °C in the valley, where the factory is located.
To cool the air in the production area is was decided to make two new AHUs for adiabatic cooling and to connect these to the existing duct work.
In each AHU a customised rack with special high pressure nozzles is installed to produce a uniform mist across the entire duct section measuring 2,5m x 2,5m. One 250 kg/h humiFog water supply cabinet is installed outside each AHU.
The two humiFog systems are similar apart from that on AHU is located in the production area while the other one is located outside.
In this way adiabatic cooling replaces a traditional cooling coil, reducing the energy consumption to a minimum. At full capacity the two humiFog systems atomise 500 kg of water in total per hour. For each litre of water absorbed into the air, the energy consumption is no less than 700 W creating a total cooling effect at 350 kW.
After one year of operation the client still expresses entire satisfaction with the two humiFog systems installed. The demineralised water has reduced maintenance to a minimum and still no abnormal operation has been observed.
