Design & Engineering
Engineered Before It's Built.
Every 3S project begins in engineering. Our team uses SolidWorks 3D CAD to design, simulate, and verify every component before a single piece of metal is cut — eliminating costly rework and ensuring precision at scale.
Engineering-Led Manufacturing
3S International's engineering department bridges design intent and production reality. From initial concept through final fabrication drawings, our engineers work directly with customers to develop custom solutions for generator enclosures, power system packaging, data center cooling infrastructure, and complex metal assemblies. Every design is verified in SolidWorks before it reaches the shop floor.
Engineering Capabilities
SolidWorks 3D CAD
Full 3D modeling and design verification using SolidWorks — the industry standard for mechanical engineering and fabrication design.
Custom Enclosure Design
Generator enclosures, drop-over housings, containerized power modules, and switchgear enclosures designed to customer specification.
Data Center Heat Exchangers
Liquid and immersion cooling heat exchanger design for hyperscale AI data center applications — engineered for thermal performance and structural integrity.
Structural Skid Design
Generator skid bases, structural sub-bases, and seismic-rated housings engineered to meet site-specific load and code requirements.
Fuel System Engineering
Above-ground tanks, sub-base fuel tanks, UL-142 systems, day tanks, and fuel transfer systems designed and documented for compliance.
System Integration
Control wiring, exhaust and silencing systems, louvers, automatic closures, and cold-weather packages engineered as integrated assemblies.
Our Engineering Process
Requirements Capture
We work directly with your team to understand site conditions, load requirements, code compliance needs, and delivery constraints.
3D Design & Modeling
Our engineers develop full SolidWorks 3D models, enabling visual review and interference checking before any fabrication begins.
Design Verification
Structural and thermal analysis confirms the design meets performance requirements. Drawings are reviewed and approved before release to production.
Fabrication Release
Approved drawings and cut files are released to our fabrication team — CNC, laser, robotic welding — for precision production.
