In Hungary alone, a total of about 3.000.000 m2 suitable roof surface
”Wherever there is a sufficient supply of industrial water available, roof cooling spray systems have proved to be the most effective and economic way of heat protection.
”Payback is expected in the first summer for large industrial halls with significant internal thermal expansion
”Although the technology uses industrial water, the total water footprint of the technology is still 25-90% lower than the energy required for the cooling power generated by Roof Cooling (depending on the type of power plant).
”With a self-learning, smart control system, we spray just the right amount of water at every point on the roof, at every moment, for maximum evaporation. No dry surfaces, no puddles.
Industrial water demand on the order of 0.65m3 / m2 per season
| Outside roof temperature | Inside air temperature | Inside ceiling temperature | |
| Without WaterFilm Technology | 62-78 °C | 32-43 °C | 46-51 °C |
| With WaterFilm Technology | 30-32 °C | 26-28 °C | 30-34 °C |
WaterFilm Technology®, an EU SME Innovation, offers solution for all of them:
Eliminates technical and labour-protection emergency shutdowns related to summer overheating and reduces the amount of waste.
Prevents the dilatation of the roof – eliminating leakage.
Prevents automatic shut-downs of overheated air conditioners, and reduces their energy consumption by as much as 80 percent.
In Hungary: as from 2017, 30-50% tax allowance on energy efficiency investments.
Validation, efficiency measurements, calculations:
“There should be focus on measures which avoid overheating, … and further development and application of passive cooling techniques, primarily those that improve indoor climatic conditions and the micro-climate around buildings.” — PARAGRAPH (25) - 2010/31/EU Directive

ENVIRONMENT PROTECTION AND SUSTAINABILITY:
WaterFilm Technology® meets the most stringent criteria:
LABOUR PROTECTION:
According to customer’s information, since WaterFilm Technology® was experimentally introduced in the plants of GM (Opel) Szentgotthárd and Dunapack Zrt. (in 2008 and in 2006 respectively),
The payback depends largely on how much of a problem the heat is at the moment: typically between 2-3 months and 2 years. The quickest payback is expected when:
For a 10.000 m2 hall, the installation of the system costs in the order of 100 million HUF, which in many cases is paid back in the first season.
The annual cost of operation, remote monitoring and maintenance is in the order of 5-10 million HUF. The industrial water demand of the system is about 0.65m3/1m2/year.
Our gap-filling innovation has won European Seal of Excellence from the European Commission and has been mentioned in several articles.
