FEATURED PROJECTS: ENHANCING SIGNAL SAFETY AT VIETNAM'S LEADING OIL REFINERIES

Viet Thang Loi is proud to be a specialized solution provider, contributing to the safe and continuous operation of national key petrochemical plants, where Ex (Explosion Protection) safety is the highest priority.

1. PROJECT: COMPREHENSIVE CONTROL SIGNAL PROTECTION – DUNG QUAT OIL REFINERY

Client: Binh Son Refining and Petrochemical Joint Stock Company (BSR) – Dung Quat Refinery

Industry: Oil & Gas / Petrochemical (Capacity: 6.5 million tons of crude oil/year)

Core Solution: Surge and overvoltage protection for control signals

Featured Brand: Eaton MTL (MTL Instruments)

Challenge: The harsh refining environment presents high risks of overvoltage, lightning surges, and electromagnetic interference. The Control (DCS/ESD) systems in Hazardous Areas require absolute protection to ensure signal accuracy and continuity, preventing catastrophic incidents.

Solution: We supplied and integrated **Surge Protection Devices (SPD)** and **Safety Barriers** from **MTL** (Eaton MTL Instruments) for thousands of analog and digital signal points. The MTL solution ensures signals from the hazardous area are safely isolated and protected against overvoltage events that can damage equipment.

Value Delivered: Significantly **reduced risk** of damage to control and measurement equipment (PLC/DCS). **Ensured signal integrity and accuracy**, allowing for continuous and stable plant operation at high capacity.

2. PROJECT: SAFE COMMUNICATION AND PROTECTION SYSTEM UPGRADE – NGHI SON REFINERY

Client: Nghi Son Refinery and Petrochemical LLC

Industry: Oil & Gas / Petrochemical (Capacity: 10 million tons of crude oil/year)

Core Solution: Intrinsically Safe Signal Communication and Loop Protection

Featured Brand: Eaton MTL (MTL Instruments)

Challenge: As Vietnam's largest refinery, Nghi Son required dedicated **Intrinsically Safe (IS)** communication solutions to connect Field Instruments with the control room. The system needed to maintain the highest level of Ex safety while allowing for easy maintenance.

Solution: Viet Thang Loi supplied **MTL Safety Barriers** and **Signal Isolators** certified for **Intrinsically Safe** operation. We deployed MTL's industrial communication solutions to ensure secure and noise-free data transmission in Ex Zone 1/Zone 2 environments, meeting the plant's stringent operational demands.

Value Delivered: **Provided a reliable Intrinsically Safe protection solution**, preventing the risk of explosion from electrical sparks. **Optimized communication capabilities** between field devices and the control system, paving the way for future capacity expansion.

OUR COMMITMENT: The successful execution of key projects at Dung Quat and Nghi Son affirms our deep technical expertise in Ex safety solutions and signal protection, leveraging world-leading technology from MTL.
