industrial chiller 3d model

Create a realistic industrial rooftop air-cooled chiller unit with 8 top-mounted axial fans for a website hero section. The model must look photorealistic and industrial, similar to a real commercial chiller. It should have a long rectangular metal chassis with 8 evenly spaced circular fans on top. Some side sections must be open, showing visible internal pipes, compressors and cooling components. Only model visible interior parts inside the open areas. Do not model hidden internal zones, underside geometry, or unseen back details. Keep geometry optimized and clean. Simplify pipe curvature and avoid tiny screws or micro elements. Target 80k–150k triangles max. Use max 3–4 materials and preferably a texture atlas. Texture resolution max 2048px (prefer 1024px). No 4K textures, no complex transparency. Export as optimized GLB under 4MB. Centered pivot. lightweight slow fan rotation animation only.
