PROJECT SUMMARY
Location: The new parliament building in Bangkok Dusit District, Thailand
Installed Equipment: Open skid industrial gensets @ 400V, 3-Phase, 50Hz, with CEA7 Controller
Special Configuration: Remote radiators with heat exchangers
Sector: Government
ABOUT THE PROJECT
Sappaya-Sapasathan, known as Thailand's new parliament building, serves as the meeting place for the Thailand National Assembly. It is located in the Dusit District in Bangkok, on the east bank of the Chao Phraya River, and spans approximately 424,000m², making it the world's largest parliament building.
The building houses two main chambers, one for the House of Representatives, and the other for the Senate. It also includes various facilities such as museums, seminar rooms, banquet halls and a convention centre. Hence, ensuring reliable power supply is extremely important considering its importance in the national legislative processes.

POWER SOLUTIONS
HIMOINSA generators powered by Mitsubishi engines, packed with Stamford alternator and CEA7 controller, in total of 5.5MW of HIMOINSA power, are installed in the new parliament building, to provide reliable and high-efficiency emergency back-up power supply.
With advanced technology that allows integration with domestic power grids, in case of grid failure, the gensets can operate automatically within seconds to guarantee a swift recovery of all essential services, provide sufficient and efficient power to support the daily operation of the parliament building.
Remote radiators were installed, providing a more flexible and controlled way to manage heat generation of the gensets, and to achieve the following benefits:
Space Optimization
The heat source is diverted to the roof of the building, away from the genset room, allowing for better layout design and utilization of space.
Noise Reduction
By separating the heat source, noise generated by the cooling process can be minimized and directed away from occupied areas.
Improved Efficiency
Dedicated radiator design is optimized for cooling needs, leading to better heat dissipation and overall system efficiency.
Targeted Heat Control
Allows for focused heat management in specific areas where it is most needed.
Maintenance Accessibility
Easier access to the radiator for cleaning and maintenance due to its separate location.
To facilitate the remote radiator, heat exchangers are installed to transfer excess heat from the engine coolant to the water-cooling system. The process is crucial for managing the engine's temperature, which regulates the heat produced during the engine's operation, ensures safe and efficient operation, prevents overheating and maintains optimal performance.
The weather in Bangkok can be extremely hot, especially during its dry season with daytime temperature reaching exceeding 38°C or so.
Also, due to the city’s dense urban environment and limited green spaces, Bangkok is experiencing ‘urban heat island’ effect. The new parliament building is seated in the city center, where temperatures are even higher compared to surrounding rural areas. To prevent overheating issues that could lead to generator failure or shutdowns, the gensets are packed with high-powered fans and electronic control panels, allowing the gensets to perform optimally even at high temperatures.
“The new parliament building is an outstanding landmark in Bangkok, reflecting Thailand's cultural heritage and the importance of its legislative processes, we are proud that HIMOINSA gensets can be part of this significant project”, said Panchanok Temiyasen, Managing Director of Gateway Intertrade Co. Ltd., HIMOINSA’s authorized distributor in Thailand since Y1999. “During the past two decades, HIMOINSA generators have been successfully applied in hundreds of commercial, residential, government and industrial projects across the country. Customers trust us to provide one-stop power solutions from the installation to aftersales.”
