Roxia PP Plate Pack
Successful Commissioning of Advanced Roxia Plate Pack
Roxia is pleased to announce the successful commissioning of its advanced Plate Pack at Albemarle’s La Negra Plant in Chile. The Plate Pack, featuring polypropylene (PP) plates with duplex steel and hastelloy nserts, was installed in one of Albemarle’s three PF 28/38 filters, marking another important milestone in the collaboration between the two companies. Roxia faced some challenges during the initial delivery last year, resulting in the need for repairs and replacements. However, with strong collaboration between Roxia SPA, the headquarters delivery team, suppliers, and Albemarle, the issues were swiftly addressed. This concerted effort ensured that the final product fulfilled Albemarle’s expectations.
Key factors behind the success of this project include Roxia’s commitment to providing the highest quality products and services, a willingness to tackle challenges head-on, and a deep alignment with the company’s core values. This achievement demonstrates Roxia’s ability to overcome obstacles and deliver reliable solutions through teamwork and dedication.

Albemarle’s Technology manager and operation processes, Felipe Fierro, shared his appreciation for Roxia’s contribution:
“It is my pleasure to express my sincere appreciation for your
outstanding support in the execution of the RM 23018 LN Filter
capacity increase project. Your commitment has been critical to the
success of this first phase of the project.
While the expansion process was not without deviations, I
appreciate the commitment and accountability to respond and
resolve them. The first step has been successfully completed, and we count on
your support to continue with the next stages”, says Fierro.
Expansion Packages and On-Site Advisory Services

This achievement represents not only a technical accomplishment but also a testimony of trust between Roxia and Albemarle. By meeting customer expectations, Roxia continues to establish itself as a trusted provider of innovative filtration solutions across industries.
