From Power Generation and
Oil & Gas to Mining and HVAC,
PT. CCIT Group Indonesia leverages proprietary CFD technology to optimize performance and engineer reliability.
A few things we’re great at CFD Services
At PT. CCIT Group Indonesia, we don’t just run simulations; we decode the complex language of fluid behavior to solve real-world engineering bottlenecks. Our expertise is anchored by CFDSOF, our proprietary CFD code, giving us the unique ability to go beyond “out-of-the-box” software limitations.
Thermal Management & Combustion Optimization
In the Power and Energy sectors, heat is both the product and the enemy. We specialize in the high-fidelity modeling of utility boilers and furnaces. By simulating complex chemical reactions and heat transfer, we help plant operators reduce NOx emissions, eliminate tube-eroding hot spots, and transition to alternative fuels without risking structural integrity.
Complex Flow Assurance
For our Oil & Gas and Mining partners, we bridge the gap between theoretical flow and operational reality. We are experts at predicting transient phenomena such as liquid slugging in subsea pipelines and slurry transport in mining operations. Our simulations identify erosion-prone zones and pressure surges before they lead to costly downtime or environmental hazards.
Industrial Ventilation & Safety (HVAC/EPC)
Whether it’s a high-rise data center or a deep-underground mine, we ensure the air moves exactly where it needs to. We excel at modeling smoke extraction systems, contaminant dispersion, and thermal comfort. Our “Digital Twin” approach allows EPC firms to validate their designs against international standards (like ASHRAE or API) before a single piece of ductwork is installed.
Custom Solver Development
The “CCIT Advantage” is our ability to look under the hood. While others are limited by commercial software licenses, we own the source code. If your project involves a non-Newtonian fluid, a unique chemical reaction, or a specific boundary condition that doesn’t exist in standard libraries, we develop the physics for you within CFDSOF.
Data-Driven Design Optimization
We don’t just tell you what is happening; we tell you how to fix it. Our consultancy services provide actionable engineering recommendations. By comparing dozens of design iterations in a virtual environment, we help you find the “Goldilocks” zone—where performance is maximized and CAPEX/OPEX are minimized.
Our Promise: We turn turbulent data into clear, decisive engineering pathways.
The Secret of Success:
Beyond the Black Box
In the world of high-stakes engineering, “good enough” is a liability. For PT. CCIT Group Indonesia, the secret of our success isn’t found in a brochure or a standard software license. It is found in our refusal to accept the limitations of the “Black Box.”
1. The Power of Ownership: CFDSOF
Most consultancy firms are users of technology; we are creators of it. The heart of our success is CFDSOF. By developing our own proprietary CFD code, we have stripped away the barriers of commercial solvers. We don’t wait for a software update to solve a unique multiphase flow problem in a Natuna Sea pipeline or a combustion instability in a Java power plant—we write the physics ourselves.
2. Bridging the Academic-Industrial Divide
Our success stems from our roots. Born from a deep foundation in research and computational fluid dynamics, CCIT Group maintains the rigor of a laboratory with the speed of a Tier-1 EPC contractor. We don’t just provide “pretty pictures”; we provide validated numerical certainty that stands up to the most stringent international audits.
3. Precision in the “Grey Areas”
Where others see a “general fluid,” we see the nuance of non-Newtonian drilling muds, the chaotic turbulence of a cooling tower plume, or the delicate thermal balance of a green building. Our secret is specialization. We focus on the high-energy, high-risk sectors—Power, Oil & Gas, and Mining—where the cost of error is highest and the demand for precision is absolute.
4. The “Engineering First” Philosophy
The code is our tool, but engineering is our soul. We measure our success not by the complexity of our meshes, but by the measurable ROI of our clients. Whether it is a 2% increase in boiler efficiency or a 30% reduction in erosion-driven maintenance, our results are grounded in the physical reality of the plant floor.
5. Local Insight, Global Standard
As an Indonesian company competing on the global stage, our success is built on local accessibility and global capability. We understand the specific environmental, regulatory, and operational challenges of the Indonesian energy landscape, and we solve them with world-class computational power.
“Our secret is simple: We own the code, we master the physics, and we deliver the reliability that keeps the world’s most critical industries moving.”
Portfolio
While the following case studies highlight over 20 high-profile engagements with industry leaders like PT PLN (Persero), PT Pertamina, and PT Rekayasa Industri, they represent only a focused snapshot of our broader technical footprint. Since 1994, PT. CCIT Group Indonesia has conducted hundreds of specialized simulations, ranging from secret internal R&D for global energy firms to rapid-response failure analyses for local power plants. Our success is built on the flexibility of our proprietary CFDSOF solver, allowing us to pivot from modeling vast coastal thermal plumes in the Java Sea to the microscopic chemical reactions inside a CO2 stripper. Whatever your fluid challenge—regardless of scale or complexity—our legacy of completed projects is proof that we have the validated experience to engineer your solution.

Client Testimonials
Power Generation (Thermal Dispersion)
“The complexity of the North Jakarta reclamation project presented a significant risk to our cooling water systems. CCIT Group’s thermal dispersion study was instrumental in helping us visualize the long-term impact on PLTGU Muara Karang. Their proprietary CFDSOF solver provided a level of detail that gave our engineering team the confidence to proceed with critical infrastructure adjustments.”
Senior Engineer, PT PLN (Persero)
Petrochemical & Process (Equipment Redesign)
“We faced persistent efficiency drops in our CO2 Stripper Reboiler that standard maintenance couldn’t solve. The CCIT team performed a ‘digital autopsy’ using CFD that revealed internal flow stagnation we hadn’t considered. Their subsequent redesign didn’t just fix the problem—it optimized our steam consumption and stabilized the entire process string.”
Plant Manager, PT Pupuk Iskandar Muda (PIM)
Oil & Gas (Flow Assurance)
“In offshore operations, vibration and erosion are constant threats to asset integrity. CCIT Group analyzed our compressor piping headers with extreme precision. By identifying the specific turbulence kinetic energy nodes, they provided a mitigation strategy that reduced pipe vibration by 40%, significantly extending our maintenance cycles.”
Lead Specialist, PT Pertamina
EPC & Infrastructure (Project Validation)
“Working with CCIT on the Suralaya 8 thermal deflector project was a seamless experience. Their ability to recalculate complex thermal dispersion models quickly as reclamation plans evolved was vital to our project timeline. They are more than consultants; they are high-level technical partners who understand the rigors of EPC requirements.”
Project Director, PT Rekayasa Industri
Renewable Energy & Aerodynamics
“Designing a 100 KW wind turbine for the Indonesian landscape required specialized aerodynamic analysis. CCIT’s expertise in blade design and flow simulation was world-class. Their team’s deep understanding of fluid-structure interaction ensured our design met all performance targets before the first prototype was even built.”
Technical Advisor, Ministry of Energy and Mineral Resources (ESDM)
Operational Excellence (Fuel Flexibility)
“As we moved toward utilizing a wider range of coal ranks at PLTU Suralaya, we needed a roadmap for boiler safety. CCIT provided a comprehensive ‘Coal Wide Range Study’ that mapped out flame characteristics and slagging risks for every blend. This data-driven approach has been a cornerstone of our operational flexibility strategy.”
