ARJA Refurbishment: Certified Quality Backed by Over 40 Years of Experience
With more than 40 years of experience in the design and manufacture of impact crushers and in the development of turnkey projects for complete plants, ARJA continues to evolve to meet the real needs of the market.
The growing demand for refurbished equipment has led us to expand our service, offering not only the complete refurbishment of ARJA machines, but also of equipment from other well-known manufacturers in the sector.
Refurbished Equipment with an Official 1-Year Warranty
Both new equipment and ARJA-certified refurbished machines come with the same official one-year warranty, maintaining the quality, robustness, and durability that define our company.
At ARJA, the age of a machine does not determine its value: every refurbished unit is updated with the latest technological and design versions, ensuring maximum performance.
A Process That Adds Value for the Customer and the Local Environment
Our strategy includes recovering used machines from local customers, integrating them into a complete refurbishment process, and certifying them under ARJA standards.
This system makes it possible to offer equipment in excellent condition, with an official warranty and approximately 25% cost savings compared to new equipment, while maintaining exactly the same operating conditions.
