TH EN JP CNTechnical System Engineering Co., Ltd. is a specialist in designing and installing electrical systems, as well as providing comprehensive engineering projects for industrial plants, office buildings, and various agencies—especially within Chonburi and Rayong, which are major industrial hubs. The company offers services ranging from contracting low- and high-voltage transformer installation to internal factory electrical systems, HVAC, cleanrooms, and chilled water piping systems. Covering all client requirements, the team of engineers has the knowledge, expertise, and real-world experience to ensure work quality meets international standards. Whether for electrical systems, HVAC, or machinery maintenance, customers can have confidence in safety, cost-effectiveness, and reliability.
One of the company’s core specialties is transformer installation contracting, both high- and low-voltage. Transformers are essential for all factories and buildings. Installing high-quality, standard-compliant transformers ensures stable power supply, reduces voltage dips and outages, and prolongs the lifespan of machinery. The company also offers full factory electrical system design and upgrades—from switchboard installation (Switchboard), MDB load centers, control panels, to system improvements such as power factor correction and CAP BANK inspection, enhancing electrical system stability in industrial plants.
In order to keep production and business operations uninterrupted, the company provides installation of generators and power backup systems like UPS, as well as voltage stabilizers. These systems protect against damage from power outages or voltage drops that could halt machinery or degrade product quality. The team also offers inspection, upgrade, and maintenance services for existing backup power systems, to extend lifespan and enhance safety of the factory’s electrical system.
Safety is another cornerstone. The company installs fire alarm systems and fire protection systems, including automatic fire suppression for buildings and factories in Chonburi and Rayong. Having these systems in place helps reduce fire risks and protects both lives and property.
Besides electrical works, Technical System Engineering Co., Ltd. is also skilled in designing and installing air conditioning and ventilation systems (Ventilation, AHU, Ducting System)—including supply air ducts, return air ducts, exhaust ducts, and fresh air ducts. The design is tailored to the building or factory’s specific characteristics.
Another important service is installation of clean rooms (Clean Room), sterile rooms used in food, pharmaceutical, and electronics manufacturing, as well as medical laboratories. The company can provide full integration of HVAC, air showers, and humidity control rooms.
For large buildings and industrial plants, the chilled water piping system (Chilled Water Piping System) is central to temperature control. The company designs and installs chilled water piping, cooling systems, and chillers, and also provides maintenance for existing systems. A high-quality chilled water system helps make air conditioning stable, energy efficient, and prolongs the lifespan of machinery.
To keep electrical systems and machinery running continuously, the company provides Preventive Maintenance (PM) services—checking and maintaining electrical control panels, ACB capacitor panels, MDB cabinets, performing Function Tests and CAP BANK checks to ensure electrical system readiness. Additionally, services include maintenance of industrial machinery systems such as PLCs, process upgrades, machine relocation, and installation of machinery of all sizes: large, medium, and small.
With extensive experience and expertise in full-scope electrical and engineering systems, Technical System Engineering Co., Ltd. has gained the trust of large factories and buildings in Chonburi and Rayong. Whether it’s transformer installation, high- & low-voltage electrical systems, factory electrical systems, HVAC, clean rooms, or chilled water piping, every job is performed by specialist engineers who uphold safety and quality standards.
