1 Challenges and Goals of Production Expansion

Canon Thang Long MOLT2 Factory, part of a large manufacturing complex, needed to expand and improve cooling performance for new production areas. This expansion required a flexible energy solution that could be deployed quickly in the outdoor area and was economical, following the success of the previous TES project.

Main project requirements:

1. Provides additional, stable cooling capacity for extended areas.

2. Continue to optimize electricity costs during peak hours.

3. Ensure the solution is durable and can withstand outdoor environmental conditions.

2 ESS Vietnam's Outdoor Cold Storage Tank Solution

ESS Vietnam has deployed an outdoor concrete Cold Storage Tank (TES) solution with a capacity of 4,000 kWh , suitable for the expansion needs of Canon Thang Long MOLT2 Factory.

• Operating Principle: The TES system operates by charging (freezing) at night (low-peak hours) and discharging (defrosting) during the day (peak hours), helping the main Chiller system reduce operating load.

• 4,000 kWh Capacity: This stored cooling capacity ensures a stable and efficient cooling supply, effectively supporting the factory's production process.

• Outdoor Location: Placing the tank outdoors takes advantage of available space, while the reinforced concrete structure ensures durability and long life for the system.

3 Investment Efficiency and Field Implementation Process

This project is a testament to the trust of major partners like Canon in the ability to optimize operating costs that the TES solution brings.

• Stable Economic Efficiency: With the ability to save electricity costs during peak hours, the project achieves a payback period (ROI) of 4 years , a reliable financial result in the industrial sector.

• Delivery Time: The project was completed and handed over for installation in November 2018 , ensuring the factory's production expansion schedule.

3.1 Detailed Installation Procedure

The construction process of outdoor Cold Storage Tanks at MOLT2 is carried out according to high standards, ensuring quality and durability:

1. Concrete ice storage tank at Canon Thang Long Molt 2 factory: Completed solid concrete tank structure, ready for internal equipment installation.

2. Waterproofing membrane and metal support frame: Install a specialized waterproofing membrane to optimize insulation, and install a support frame to secure the heat exchanger.

3. Heat exchanger inside the tank: Install the heat exchangers in the designated position, this is the core part of the cold charging/discharging process.

4. Connect to main manifold: Complete the connection of the heat exchangers to the main manifold, preparing for connection to the factory's Chiller system.

5. Canon Vietnam factory engineers inspect the construction site: The construction process is always closely monitored, ensuring compliance with all technical and safety standards.
