Mechanical Engineer | Commercial & Industrial Refrigeration | MEP

I am a Mechanical Engineer specializing in commercial and industrial refrigeration system design. I have worked on supermarkets, hotels, cold rooms, distribution center cold storage, blast freezers, ULO storage, compressed air systems, water loop systems, systems with natural refrigerants. Services I Offer Refrigeration Engineering Refrigeration System Design HVAC Design MEP Design Mechanical Design BIM Modeling Load Calculations Equipment Selection Construction Documentation Shop Drawings Bills of Materials (BOM) Cost Estimation Software Revit MEP AutoCAD SolidWorks Catia Danfoss Coolselector®2 Bitzer Software CoolProp Microsoft Excel And more My work has been used on projects in Serbia, Croatia, Russia, Uzbekistan, the UAE, Qatar, Saudi Arabia, Slovenia, the UK, Poland, Italy, and Armenia. I can take a project from concept through construction documentation, preparing Revit and AutoCAD drawings, BIM models, equipment schedules, bills of materials, cost estimates, technical and commercial proposals, and all other engineering documentation required for execution. I am comfortable working independently as well as coordinating with architects, structural engineers, and other MEP disciplines. If you need refrigeration engineering support—whether for a complete system design, Revit modeling, BIM coordination, AutoCAD documentation, or cost estimation—I can provide practical solutions tailored to your project's requirements. I can also design the HVAC portion of a project when refrigeration waste heat is utilized, allowing for a fully integrated system design. However, my primary specialization is refrigeration engineering. You are in the right place if your project involves design temperatures of 10°C (50°F) or below, or if you are working with equipment from manufacturers such as LU-VE, Advansor, Danfoss, Bitzer, Rivacold, Dorin, Güntner, Alfa Laval, Hillphoenix, Hussmann, Heatcraft, Copeland, Emerson, CAREL, Eliwell, Dixell, Schneider Electric, Siemens, SCM Frigo, Daikin, Arneg, Epta, True Manufacturing, Turbo Air, and Zero Zone.
