LTG AIR TECH SYSTEMS

Surface technology

Whatever method of surface treatment you use – painting, powder coating, galvanising or sand blasting – optimum air technology will improve the quality of your products and make your system more cost-effective.
Printed or painted parts such as plastic bottles, metal strips or metal packaging must be dried and then cooled for further processing. To ensure drying results of consistent quality, the temperature distribution and air flow must be uniform over the whole surface. LTG tangential fans ensure perfectly even air distribution. Thanks to their small dimensions and special flow principle with 90° or 180° deflection, the external dimensions of such installations can be reduced while maintaining the same process space. In addition, the discharge length of the fans can be matched exactly to the width of the conveyor or batch. That means the air flow conditions are the same in wider machines. This considerably simplifies the design and development of model series.
Before a coating is applied in the form of a granulate, it is essential to preheat the surface correctly. The air flow must be exactly controlled to ensure that the right amount of heat is applied to the granulate fill. An uneven air distribution would impair the quality of the finished product. LTG tangential fans allow you to meet these and similar requirements at reasonable cost.
It is also often necessary to clean surfaces or remove foreign particles. LTG tangential fans can assist by applying a gentle air jet to the entire width of the surface being processed. Thanks to their through-flow principle, they can be integrated easily and economically into your facility. Moreover, their low pressure buildup reduces the system’s energy consumption and increases its efficiency.

LTG tangential fans are particularly useful for surface treatment. This is because of their ability to distribute air very evenly over large areas. They allow you to set up efficient and high-quality thermal processes at low cost. Thanks to their flow principle with 90° or 180° deflection, you can do without expensive baffles and nozzle boxes and enjoy the benefits of an elegant, space-saving and economical design. Our LTG fans are available in a wide range of sizes and ratings, including easy-to-clean stainless steel versions. For high pressures we offer high-quality and versatile LTG centrifugal fans. Like our tangential fans, they are available in versions that are resistant to high temperatures and corrosion. Finally, LTG's fan range includes highly efficient LTG axial-flow fans. These are ideal for large air quantities.

Our engineering services are available if you need help in designing air and heating systems and have to select exact values of parameters that are important for your processes, such as air temperature, heating and cooling capacities, and humidity. We'll work with you to develop an optimum design and verify it using state-of-the-art aids such as computational fluid dynamics (CFD) and tests at our technical centre.
