We have developed a multi-tube heat exchanger with NFX-7970 baked lining construction.
Nippon Fluorine Industry has developed a heat exchanger with a fluororesin baked lining "NFX-7970" applied to all liquid and gas contact parts. Heat exchangers used in manufacturing equipment that require corrosion resistance and high purity have traditionally utilized fluororesin molded products that cannot withstand pressure or vacuum. The "NFX-7970" baked lining features a special specification that allows for the inner surface of narrow heat transfer tubes to be lined with high-purity fluororesin, capable of withstanding both positive and negative pressure. The main body of the heat exchanger is manufactured by Kimura Chemical Machinery Co., Ltd. 【Features】 ○ Excellent high purity ○ Does not crack under impact ○ Difficult for scale to adhere ○ Usable under positive and negative pressure ○ Excellent acid and alkali resistance, allowing for versatile use For more details, please contact us or download the catalog.
