Industrial Refrigeration

Midwest Mechanical Systems delivers complete refrigeration solutions — from system design and installation to ongoing service and preventive maintenance.

We support ammonia (R-717), CO₂ (R-744), and legacy Freon-based systems, helping our clients operate safely, efficiently, and with minimal downtime.

Our turn-key systems integrate seamlessly into your facility. We evaluate your current usage, work closely with your team or general contractor, and design systems tailored to your project and long-term needs. With licensed engineering in house, we don't guess — we run the calculations, determine space loads, and define all utility requirements. Whether it's DX, liquid recirculation (overfeed), or flooded systems, we have the solutions that fit your needs.
