Better Capture, Lower Energy, No Shutdown

Better capture, lower energy, no shutdown.
CFD-backed ventilation engineering for manufacturers

SIEC optimizes industrial ventilation for manufacturing and process facilities across the Southeast. Using computational fluid dynamics and field-validated engineering, we improve capture efficiency, reduce wasted airflow and fan energy, and solve entrainment problems without requiring extended production shutdowns.

PE-led ventilation optimization for Southeast manufacturers. improve capture, cut fan energy, and document compliance paths without extended shutdowns.

CFD-backed capture and fan decisions for Carolinas manufacturers.

Energy Efficiency Gains

Eliminate waste from duct leaks and exhaust imbalances. Cut 10 to 15 percent via fan balancing

Downtime Minimization

Non-disruptive assessments resolve airflow bottlenecks and exhaust failures, reducing unplanned halts by 15% in variable processes

Scalable Integration

Builds on Mechanical Engineering for system-wide fixes; extends to simulation for predictive modeling and 4.0 sensors for monitoring

Our Optimization Process

Initial Assessment

Scan HVAC for airflow inefficiencies, exhaust leaks, and compliance gaps – no production impact, focusing on root pains like fume buildup

Analysis & Modeling

Analyze and model optimizations to predict 10 to 15 percent energy gains, integrating exhaust flow with your mechanical setups for precise root fixes

Retrofit Implementation

Deploy low-capex solutions like slotted hoods or damper adjustments; managed via project expertise to minimize disruptions

Validation & Handover

Measure outcomes (e.g., 15% downtime drop); provide staff training for sustained reliability and documentation

Proven Results

For an NC-based plastics manufacturer, audits addressed exhaust challenges from submicron particles causing duct accumulation and fouling risks. Based on observed airflow behaviors, we selected and integrated a low-capex gas/liquid separator with a demister pad upstream, achieving 45% mass removal and 85% reduction in buildup, eliminating fire hazards and volatilized hotspots for 15% downtime cuts without production halts
For a textiles degreasing room facing OSHA PPM limits on solvent vapors, we redesigned exhaust strategies to capture fugitive emissions at source. No-disruption retrofits balanced airflow for 10 to 15 percent energy gains, ensuring compliance while minimizing bandwidth strain – yielding $50K annual savings via 179D-eligible tweaks
