Facility managers need mechanical systems that won’t fail under pressure, temperature, or inspection. We engineer those systems and stand behind every connection.
Hartwig Mechanical brings over 65 years of experience to cold storage and food-grade processing plants across Northern Illinois and Southern Wisconsin. From sanitary welding to process piping, our team delivers precise mechanical solutions that meet high standards for safety, cleanliness, and compliance. We understand that these facilities can’t afford downtime, and we’re built to respond fast, work clean, and deliver results that last.
Cold storage and food-grade environments need precise, compliant mechanical work. Hartwig Mechanical performs sanitary welding and installs insulation valves that meet CIP (Clean-In-Place) standards to help prevent contamination and downtime. We follow controlled procedures and preventative maintenance strategies that support GMP compliance and help facility managers stay audit-ready. Every technician operates under a drug-free workplace policy and is trained to work efficiently and safely in sensitive production zones. Whether supporting new builds or updating aging infrastructure, we deliver long-term performance that holds up under pressure.
We design and install commercial and industrial HVAC solutions that prioritize clean airflow, temperature stability, and moisture control. Our systems align with sanitation protocols, help maintain product integrity, and reduce contamination risks while meeting regulatory standards for food-grade environments.
Hartwig Mechanical specializes in sanitary welding that meets industry standards for food-grade piping and stainless-steel systems. Every weld is made to prevent bacteria traps, support CIP procedures, and pass inspection without issue.
Absolutely. We regularly support clients during expansions or production upgrades, helping them integrate new systems into existing infrastructure with minimal disruption. We also assist with layout redesign, new equipment tie-ins, and phasing the work around active operations.
