A screen with good quality can play colorful videos smoothly and unobstructedly, giving a visual enjoyment.
A series of thin metal plates parallel to each other and pressed with a distance column are stacked to form a plate air-Air Heat Exchanger. The main components are heat transfer plates, outer frame sealing plates, compression device and so on.
The plate adopts full welding seal, flue gas and air cross flow between the plate for heat exchange. It`s suitable for air preheating and waste heat recovery in steel, chemical, electric power, battery and other industries, especially suitable for ultra-high temperature air to air heat exchange field.
Tranp`s Plate Air-Air Heat Exchanger is especially suitable for heat exchange between gas medium with high corrosion, high dust and high humidity.
The surface of the heat exchange plate is smooth with strong self-cleaning ability, so it is easy to clean. And multiple process is available, which is customized for different working conditions. Besides, the processing capacity can be as low as ten, but also as high as thousand CBM, therefore it`s widely used in waste heat recovery. What is more, the plate adopts advanced welding equipment and technology, combined use of resistance welding and manual welding between plates ensures that the weld joint is not easy to burst.
