The first domestic CTA crystallizer was born in Dalian Hitachi Machinery Co., Ltd.

The first domestic CTA crystallizer, which was carefully developed in 14 months, was successfully filled in the domestic manufacturing of refined terephthalic acid chemical equipment in Dalian Hitachi Machinery Equipment Co., Ltd., ending the long-term dependence on imports.

CTA crystallizer is the key equipment for the production of purified terephthalic acid, which is an important raw material for the production of chemical fiber and plastic products. Previously, CTA crystallizers were only manufactured in Belgium, Korea, and Japan.

Dalian Hitachi Machinery Equipment Co., Ltd. was established in July 1997 and has become the overseas power, petrochemical and foundry production base of Hitachi.
