Thanasak Saichuay

I have extensive experience in engineering and utility systems within industrial manufacturing, covering both electrical and mechanical utilities. Regarding electrical systems, I am experienced with transformers, MV/LV switchgear, MDB/DB, MCC, motors, VFDs, and power distribution. My expertise includes monitoring parameters such as voltage, current, power factor, and load, as well as managing system alarms and trips.

In terms of mechanical and utility systems, I have managed chillers, cooling towers, pumps, air compressors, air dryers, vacuum systems, hot water systems, and hot oil boilers. I also have experience with HVAC systems, including MAU/AHU units and cleanroom environments. I prioritize safety and system reliability in my work.

When issues arise, I systematically analyze alarms and operating parameters—such as voltage, current, pressure, temperature, flow, and differential pressure—to pinpoint the root cause before proceeding with repairs and test runs. Additionally, I have experience coordinating with production, maintenance, contractors, and suppliers on installation, commissioning, preventive maintenance, and troubleshooting. I hold certifications for boilers, hot oil boilers, natural gas station operations, electrical system inspections, interior electrical work, and energy management (including "Responsible Person for Energy" certifications for both factory operations and thermal/electrical systems).

My goal is to ensure high system availability and reliability while minimizing unplanned downtime and controlling energy consumption, all without compromising safety or system quality.
