As Southeast Asia’s digital economy surges past $300 billion in 2025 . Thailand’s Rayong Province has emerged as a strategic hub for data center investments, anchored by the Eastern Economic Corridor (EEC) initiative. The Zhonglian Data Center Rayong, operated by a subsidiary of China Zhonglian Data, stands as a flagship project in this boom—boasting a total installed capacity of 203MW upon completion, it will serve as a benchmark for cross-border computing infrastructure in ASEAN.
To ensure uninterrupted operation of high-density computing equipment, the project required HVAC solutions that combine precision control, energy efficiency, and adaptability to tropical conditions. We secured the supply contract for 4 sets of roof-top fresh air HVAC units, marking its 8th million-dollar deal in 2026 and reinforcing its position as a trusted partner for overseas engineering projects.
Core Challenges & Customized Solutions
The Rayong data center faces unique operational demands shaped by ASEAN’s market characteristics:
- Extreme Environmental Stability: High-performance computing (HPC) and AI applications require temperature control accuracy of ±0.5℃ and humidity precision of ±5% RH .
- Tropical Climate Adaptation: Thailand’s high temperature (up to 38℃) and humidity (average 75%) demand corrosion-resistant, energy-efficient equipment.
- Space Optimization: As a large-scale data center in a premium industrial zone . Floor space is at a premium—roof-mounted units eliminate the need for dedicated machine rooms.
HOLTOP roof-top fresh air HVAC systems addressed these challenges through:
- Direct Expansion (DX) Cycle Technology: Reduces energy loss by 10-15% compared to traditional water-cooled systems, with a free cooling mode that cuts operational costs by over 40% during mild weather .
- Integrated Precision Control: Equipped with HEPA 14-grade filters (99.999% particle interception) and intelligent sensors to maintain clean, stable indoor environments .
- Tropicalized Design: Aluminum alloy frames with anti-corrosion coating and rainproof structures ensure reliable operation in harsh outdoor conditions . Rapid Deployment: Modular design enables roof installation without complex ductwork, shortening construction cycles by 30% .
Why HOLTOP Stands Out for Overseas Clients
- This successful partnership reflects the company’s alignment with global engineering procurement trends .
- International Standard Compliance: HOLTOP products hold CE certification and meet ISO environmental standards, satisfying cross-border project requirements.
- End-to-End Service Capability: From customized design to on-site technical support, the company delivers “HOLTOP product + professional service” integrated solutions—now a top priority for 60% of international engineering clients .
- Localization Adaptation: Deep understanding of ASEAN’s climate conditions, regulatory frameworks, and project management practices minimizes cross-cultural risks.
With Thailand approving 7 new data center projects totaling over 96 billion THB in early 2026 .And Southeast Asia’s data center market projected to reach $8 billion this year . The demand for reliable, efficient HVAC solutions is soaring. We are poised to capitalize on this growth, leveraging its technical expertise in HOLTOP systems and global service network to support more landmark projects in ASEAN and beyond.
