R&D capability
Simulation-Driven Thermal Design
CFD flow-field simulations and FEA structural analyses are integrated throughout the entire design process, with prototype performance validated through wind-tunnel testing. A life‑cycle and dust‑accumulation model is developed for the continuous‑operation conditions of data centers, ensuring adequate thermal margins under extreme environmental conditions.
Heat dissipation capability serves both the gas turbine and power generation segments—our group’s in-house production of gas‑turbine unit cooling systems is one of the key factors underpinning our confidence in delivery timelines.
