The heat exchanger or steam coil is used to heat air for drying purposes with the heat energy supplied as steam.
The profiled plate fin with zigzag tubes is designed to accomplish effective and economical heat transfer between the internal medium of steam and the drying air.
The plate fin body of the heat exchanger consists of tubes of copper or copper-nickel that have been expanded mechanically against plate fins of aluminium. Each heat exchanger plate fin is in one piece, without slits or joints, to prevent dust particles and fibres from sticking to the plate body.
The casing or frame is made of hot-dip galvanized steel sheet and is provided with lifting eyes in each corner and attachments for a mesh filter. The manifold pipes of the heat exchanger are exposed inside the frame to enable the removal of fibres. The manifold pipe on the entry side (steam) is made of steel and coated with a corrosion protective paint. The manifold pipe on the exit side (condensate) is made of copper-nickel, and the condensate coupling is made of boiler steel coated with a corrosion protective paint.
热交换器或蒸汽盘管用于加热空气以蒸汽形式提供热能进行干燥。带有锯齿形管的异形板翅片设计用于实现有效且经济的热传递蒸汽和干燥空气的内部介质。热交换器的板翅体由管子组成已膨胀的铜或铜镍以机械方式抵靠铝散热片。每次加热换热器板翅片为一体式，无缝隙或接头，防止灰尘颗粒和纤维粘附在板体。
外壳或框架由热浸镀锌钢制成并在每个角落配备吊耳和网状过滤器的附件。热交换器暴露在框架内去除纤维物。入口侧的歧管（蒸汽）由钢制成并涂有防腐漆。出口侧的歧管（冷凝物）由铜镍制成，冷凝联接器由涂有防腐涂料的锅炉钢制成。
