In May 2025, a mission against time and technology unfolded across Europe. A Jiarong Technology team—comprising Overseas Sales Manager Zhang Tao, Project Manager & Technician Jiang Junjie, and Electrical Engineer Chen Weiqing—embarked on a critical equipment commissioning journey across project sites in Romania and Germany. Through exceptional teamwork, unwavering dedication, technical mastery, and customer-centric service, they triumphed over adversity, earning widespread acclaim.

First Stop: Romania

Forging Trust Through Expertise

1. The Spare Parts Challenge

Faced with incompatible 240mm² hard cables (customer-supplied) and 95mm² equipment interfaces, the team collaborated with our German partner company's technical director and customer to devise a solution. They pulled cables, sourced supplementary parts, and collectively tackled the challenge—ensuring system integrity. Yet another crisis emerged: some components failed due to environmental factors and operational errors and there is no spare parts available in stock locally. Through resourceful problem-solving—repurposing spare parts, reprogramming, and parameter adjustments—the team overcame the odds and started the system.

2. Breaking the Ice with Custom Programming

During thecommissioning, the team identified unstable performance due to insufficient rinse water (no external water source at site). Jiang Junjie led testing and hardware adjustments while Zhang Tao monitored operations. They pinpointed the optimal setpoints for minimum water level and top-up timing, enabling sufficient flushing and stable chemical cleaning. Chen Weiqing then optimized the program, delivering bespoke automation features:

· Post-shutdown auto-flushing

· Auto-backwash upon sand filter pressure difference high

· Operational status logging

These actions and technical innovation transformed into customer satisfaction and trust.

3. Deep Empowerment: Onsite Training

As commissioning concluded, the team took initiative to conduct training for the customer. With language barriers limiting Jiang and Chen, Zhang Tao stepped in as instructor. Leveraging his expertise and real-time insights, he explained to the client on operation, testing, inspection, and maintenance. This embodied Jiarong's promise:

We deliver not just equipment, but mastery over it.

We solve problems and prevent future ones.

Second Stop: Germany

Serving Customers Through Technical Innovation

1. Breakthrough in Communication Protocols

With visas expiring in less than 10 days at the Berlin site, the client unexpectedly requested ProfiNet PLC integration (unconventional for Jiarong) over originally mentioned standard control cabinets. The team pivoted instantly:

· Jiang Junjie: Hardware inspection/troubleshooting

· Chen Weiqing: Program rewriting

· Zhang Tao: Technical research, client liaison & logistics

Through sleepless nights, days of over-time working at the , remote work site, they achieved the ProfiNet control programming—setting a new company standard for cost efficiency and design flexibility.

2. Pursuing Perfection: Process Optimization

At the site, the team identified inefficiencies in the client's self-designed wastewater process. They launched a "Lean Initiative" and provided insights and advices to client for improvement:

· Corrected pipeline installation errors per flow diagrams.

· Updated valve specifications/control logic in client schematics.

· Proposed critical improvements: manual isolation valves for pipe maintenance,anti-siphon valves at pipeline high points,optimized permeate piping to reduce backpressure risk.

· Clarified control points and logics via detailed review.

· Enabled real-time central control room monitoring despite IT constraints, using onsite networking solutions.

3. Cross-Continental Collaboration

With incomplete piping till the last day at site, wet testing was impossible. Zhang Tao proposed to customer remote testing via a communication box after leaving the site. However, the box failed to connect in the beginning. Chen Weiqing mobilized electrical colleagues in China  for joint diagnostics despite the time difference. Through synchronized efforts—patching program (in China), manufacturer guidance, and onsite execution (Europe)—they resolved a hardware bug and get the communication box online. This paved the way for seamless post-departure remote support, to ensure project delivery.

Beyond Borders: The Jiarong Ethos

After returning, all three dove back into work:

· Jiang Junjie: Onsite at Shaanxi Yulin Project

· Zhang Tao & Chen Weiqing: Remote testing for site equipment/parameter optimization

Night after night, they sustained their commitment—ensuring zero vacuum in customer operations.

Visa limits could not constrain Jiarong's service promises. From frontline battles to remote assistance, Jiarong engineers rewrote programs, added value, and guaranteed customer success.
