The Energy Complex in Thailand, the first office complex in Southeast Asia to receive LEED Platinum certification, installed Vulcan S250 and X-PRO 1 units on their condenser water system. Within 4 months, they eliminated 330 lbs of monthly scale buildup, reduced chiller approach temperatures, and improved overall energy performance.
The Energy Complex (EnCo) in Thailand was initiated by PTT Public Company Limited (PTT) and PTT Exploration and Production Public Company Limited (PTTEP) as a project to consolidate office buildings for PTT affiliates, energy-related companies, and the Ministry of Energy. The goal: save time in business communication and boost operating efficiency.
This landmark complex has been awarded the highest level of Platinum Green Building Certification from LEED (Leadership of Energy and Environmental Design)—making it the first office complex in Thailand and all of Southeast Asia to achieve this prestigious certification. The Energy Complex serves as the prototypical building in Thailand for energy conservation, harmonious coexistence of industry and the environment, and optimal utilization of resources.

Months to Results
Even with LEED Platinum certification and advanced water treatment, the Energy Complex faced a persistent problem:
Ozone System Ineffective: Before installing Vulcan, the building used an ozone water system to treat the condenser. It could not effectively treat or manage scaling.
Massive Scale Accumulation: Maintenance crews observed massive scale particles in the basin of the cooling towers.
Every month, scale was collected from the basin and consistently weighed about 330 Lbs (150 kg).
For a building designed to be the prototype of energy efficiency, this scale buildup was directly impacting chiller performance and energy consumption—undermining their LEED Platinum mission.
Building: Energy Complex (EnCo)
Country: Thailand
Region: Southeast Asia
Models: Vulcan S250 & X-PRO 1
Location: Main return pipes of the condenser
Scope: Treats all 7 cooling towers
Integration: Added as energy efficiency support alongside existing ozone system
Vulcan S250 and X-PRO 1 installed on main return pipes of the condenser
All 7 cooling towers were treated with Vulcan
Ozone system ineffective against scale
330 lbs (150 kg) of scale removed from basins monthly
Higher approach temperatures on chillers
Increased energy consumption
Significant mineral scale reduction in cooling tower basins
Approach temperatures of chillers reduced
Lower energy consumption
Improved overall chiller performance
The Energy Complex is the first office complex in Thailand and Southeast Asia to be awarded the highest level of Platinum Green Building Certification from LEED. This prestigious recognition honors their commitment to energy conservation, harmonious coexistence of industry and the environment, and optimal utilization of resources. Vulcan technology now supports that mission by ensuring their cooling systems operate at peak efficiency.
Reduced chiller approach temperatures = lower energy use

The Energy Complex represents the highest standard of sustainable building design in Southeast Asia. When their advanced ozone treatment system couldn't stop 330 lbs of monthly scale from undermining their efficiency, Vulcan delivered the missing piece. Within 4 months, scale was significantly reduced, chiller performance improved, and energy consumption dropped—proving that even the greenest buildings need comprehensive scale prevention.
Join the Energy Complex and other sustainability leaders in choosing Vulcan for chemical-free scale prevention.
