Case study
Industry: Textiles / solvent degreasing · Region: Carolinas · Services: Ventilation · 179D
Challenge
Solvent vapor concentrations in a degreasing room approached OSHA PPM limits. Constant high-volume exhaust increased energy cost and strained plant bandwidth.
Approach
Redesigned capture strategy to address fugitive emissions at source. Balanced exhaust and makeup air for compliance without extended shutdowns. Coordinated 179D-eligible efficiency measures where applicable.
Results
OSHA PPM compliance restored; 10–15% fan energy reduction; $50K annual savings from combined ventilation and incentive-eligible tweaks. No-disruption retrofits during operating schedules.
Results vary by facility, baseline, and scope. SIEC documents assumptions and measurement approach for every engagement.
