PTFE Heat exchanger is an indispensable equipment to realize heat exchange and transfer in chemical production. There are often some corrosive and oxidizing materials in heat exchange, so the material of heat exchanger is required to have strong corrosion resistance. It can be used graphite, ceramics, PTFE Tetrafluoroethane Heat Exchanger glass and other non-metallic materials and stainless steel, titanium, tantalum, zirconium and other metal materials made. But with graphite, ceramics, glass and other materials made of fragile, large size, poor thermal conductivity, with the titanium, tantalum, zirconium and other rare metals made of heat exchangers are too expensive, PTFE Tetrafluoroethane Heat Exchanger stainless steel is intolerable many strong corrosive medium, and produce intergranular corrosion medium.

Characteristics of PTFE HEAT exchanger:

Good corrosion resistance

Because PTFE is a chemical inert material, in addition to the high-temperature elements of fluorine, the melting alkali metal, trichloroethylene, uranium hexafluoride, all fluorine kerosene, almost all of the media can work.

Good anti-fouling property

Because of the inertia, surface smoothness, PTFE Tetrafluoroethane Heat Exchanger curvature and high expansion coefficient of PTFE tube, it is difficult to scale the heat transfer surface, which greatly reduces the maintenance times of the equipment and ensures the relatively stable heat transfer coefficient and the long-term operation of the production.

Long life, low cost

Because of the absence of photosensitive gene in PTFE, PTFE Tetrafluoroethane Heat Exchanger it has excellent weathering resistance. In the strong corrosive medium its service life is 20 to 30 times times of stainless steel, plus eliminates the maintenance, the accident is caused by the loss, its comprehensive cost is definitely lower than other heat exchangers.

Good heat transfer performance

Because the heat exchanger uses the thin-walled tube, the wall thickness only has 0.5mm, 0.75mm, 1mm, so it overcomes the defects of low thermal conductivity of PTFE material, PTFE Tetrafluoroethane Heat Exchanger so that its total heat transfer coefficient can reach 150-300 (w/m²k).

Small lightweight compact structure

PTFE heat exchanger using thin-walled thin tube, resulting in heat exchanger unit volume of heat exchange area is particularly large, up to 600m²/m³ (Φ25*3 steel pipe production only 130m²/m³). In addition, the weight of plastic is very light, so in transport, installation, maintenance is very convenient.
