industrial chiller 3d model

Create a realistic industrial rooftop air-cooled chiller unit for a website hero section. The model must have 6 high-quality top-mounted axial fans facing upward, evenly spaced. The fans should look premium and industrial, with clearly defined blades and realistic metal housing, not low-detail or low-quality. The lower section must include visible compressor units and industrial piping similar to real commercial chillers. Only model visible internal components; do not create hidden interior areas. Do not model the underside or unseen back details. Keep geometry optimized and clean. Simplify tiny elements while preserving a realistic silhouette. Target 90k–160k triangles max. Use max 3–4 materials, preferably a texture atlas. Texture resolution max 2048px (prefer 1024px). No 4K textures or complex transparency. Export as optimized GLB under 4MB with centered pivot. Optional lightweight slow fan rotation animation
