3D technical animation of industrial equipment – ​​AS Technik case study

Implementation Summary:
For As-Technik, we developed a 90-second seamless loop 3D technical animation optimized for homepage playback. Based on the provided CAD (.step) documentation, we conducted a geometry audit and built photorealistic 3D models of three HVAC/R devices: a fan cooler, a water-jacket heat exchanger, and an industrial air conditioner. A key element was the implementation of particle systems, X-ray effects, and color coding to visualize invisible thermodynamic processes.

AS Technik, based in Lubin, is a valued provider of advanced heat exchange solutions. The main goal of the project was to create a flagship 90-second 3D product animation designed for the Hero section on the homepage.

The animation was designed to present the operating principles and structural features of three key products from their offering in a simple, visually appealing, and technically uncompromising manner:

• An industrial fan cooler with a dedicated ventilation system,
• A heat exchanger equipped with a water jacket,
• A high-efficiency industrial air conditioner.

The primary challenge was translating complex thermodynamic phenomena into an accessible language for B2B clients while maintaining full engineering precision.

Our process for creating industrial equipment animations was built on close work with raw technical documentation provided by the client.

The starting point was engineering design files in the .step format. The first stage involved a thorough inventory of the models – detecting and removing geometry collisions while supplying missing internal components. We then performed retopology, converting heavy CAD meshes into optimized 3D models tailored for smooth animation rendering.

The core of the implementation was revealing what is invisible to the human eye. To showcase fluid dynamics inside the equipment, we applied advanced particle systems:

• X-Ray Effect and Cross-Sections: Allowed us to “see through” steel enclosures and show the internal construction of the water jacket and cooling loop.
• Working Media Visualization: Precise animations simulating the movement of liquids, gases, and airflow through exchanger channels.
• Thermal Color Coding: Using temperature gradients (ranging from cool blue to hot red) intuitively explains the efficiency of the heat exchange and cooling process.

Geometry alone is only half the battle. To ensure the animation serves as an effective sales tool on the website, we subjected it to comprehensive post-production:

• Dynamic Technical Callouts: We introduced animated text labels (callouts) that track key equipment components in real time, indicating their names and parameters.
• Branding and Smooth Transitions: Smooth, seamless transitions between modules and a consistent visual identity for the AS Technik brand.
• Seamless Loop Animation for UX: We prepared the rendered material as a seamless video loop optimized for fast web loading and automatic playback without overloading server bandwidth.

3D technical animation significantly elevates brand communication in the B2B segment:

• Shortening the Sales Cycle: Clients understand the design advantages of heat exchangers in seconds without having to analyze multi-page 2D documentation.
• Trade Show and Presentation Tool: The versatility of the material allows it to be used in the Hero section on the website as well as during industry trade shows or sales meetings.
• Image of a Technology Leader: Combining X-ray effects with a clear particle flow diagram builds the engineering authority of AS Technik.
