Service Case Studies

Case 1: Emergency Stabilizer Repair for Semiconductor Factory

· Problem: Production line sudden shutdown, stabilizer output voltage zero

· Diagnosis: Main control board failure + output contactor burnout

· Solution: On-site within 4 hours, replaced control board and contactor, restored production in 2 hours

· Result: Prevented 24-hour production loss, saved customer hundreds of thousands

Case 2: Preventive Transformer Maintenance for Data Center

· Problem: High operating temperature, slight abnormal noise

· Diagnosis: Fan failure + loose connections

· Solution: Replaced cooling fans, fully tightened connections, cleaned insulation surface

· Result: Temperature reduced by 15°C, noise decreased, transformer life extended

Case 3: Chiller Efficiency Restoration for Plastic Plant

· Problem: Insufficient cooling capacity, extended mold cooling time

· Diagnosis: Severely scaled condenser + refrigerant shortage

· Solution: Chemically cleaned condenser, leak tested and recharged refrigerant

· Result: Cooling efficiency restored to 95%, production cycle back to normal

Frequently Asked Questions

Q1: How long do repairs usually take?

A: Simple faults typically resolved in 4-8 hours; complex repairs like transformer rewinding require 3-7 days. We offer emergency rapid service prioritizing production-stopping faults.

Q2: Do you provide warranty?

A: Yes. All repair services include 90-180 day warranty, depending on repair scope. Maintenance services also come with service guarantees.
