PT Angels Products has been actively engaged in the crystallized sugar refining industry since 2003. Now, PT Angels Products is one of the biggest companies in the field of crystal sugar refinery industrial in the province of Banten. In crystallized sugar refining, decolorization, evaporation, crystallization and drying are important processes, which need to consume a large number of steam. Moreover, food industry has high requirements for sanitation, a lot of steam needs to be used for disinfection and sterilization. Providing high quality and hygienic products is this company's core value. Therefore, they have strict requirements of the steam quantity and quality. After visiting and comparing, PT Angels Products chose ZOZEN DHL series coal-fired steam boilers, which are designed with stable combustion, sufficient output and high-quality steam. But field-assembled boilers have high requirements for on-site installation. Then, ZOZEN cooperated with local agent and succeeded in completing the installation of the boiler, which can meet the company's demand.
