Annual Maintenance Service
The "Annual Maintenance Service" offered by Xi'an Tianyu Xingchen adopts the third-party maintenance concept. Different from in-house maintenance by users and after-sales maintenance provided by system vendors, it is an innovative service delivered by a professional automation enterprise. We provide full-package maintenance for DCS, PLC and other systems of all brands across the entire plant, alongside spare parts stocking services.
From the customer’s perspective, we help improve the return on assets of automatic control systems, relieve various pressures arising from safe production, and resolve direct conflicts between customers and original system suppliers.
This third-party maintenance service excludes all procurement-related fees. Its core objective is to assist customers in analyzing and resolving faults, and guarantee a high return on assets of automatic control systems by delivering optimized system maintenance solutions.
