Generally, all industries where solvents are used or generated.The following stand out:• Printing and flexography industry.• Metal coating.• Chemical industry.• Cars manufacturing.When a low concentration brings up a high consumption, a zeolite rotary concentrator allows a reduction of volume, so increasing concentration up to auto-thermal or nearly auto-thermal levels.There are processes where polluted gases concentration is over 100% of LEL (Lower Explosion Level). In these cases, it is also possible to clean according to security precautions appropriate to avoid risks.• Preheating of polluted gases.• Water and thermal oil heating.• Water steam generation.• Heating process air.RECUPERATIVE THERMAL OXIDATIONRecuperative thermal oxidation consists of recovering gases heat once the cleaning operation is complete. This profit has several ways, including:(0,8 – 2 s) and in presence of oxygen. In these conditions, a destruction efficiency over 99% is achieved.Kalfrisa develops regenerative and recuperative thermal oxidation installations.Environmental protection concern in our society has led to develop a specific legislation on VOC’s Volatile Organic Compounds, which will affect a wide number of industries.Thermal oxidation is one of the Best Available Techniques for VOC’s elimination, which basically consists of submitting polluted gases to an appropriate temperature (750 – 1200 ºC), for a specific time THERMAL OXIDATIONVolatile Organic Compounds (VOC’s)cleaningINTEGRAL SERVICEA wide multi-disciplinary team develops each cleaning project globally. • Status analysis • Optimum proposals • Design and manufacturing• Assembly and starting-up • MaintenanceOWN MANUFACTURINGKalfrisa has its own workshop, what permits to adapt design and manufacturing to specific needs of each client. Each constructive phase is controlled with the aim of assuring an optimum answer.QUALITY- PRICEMore than 40 years of experience, the acquired know-how, the capacity of our human team and customer service result in an excellent value for money.Q
