Thermal Management Feasibility Studies


If you have a thermal management project or idea but are not sure you want to commit a lot of time, money and resources, we can perform a limited feasibility study for $3,000 (based on the project) in which we will assess various cooling methodologies, develop proof of concepts, and provide a foundation for future work for your particular application, idea or project. We will perform it in 2-3 weeks, and will provide a brief summary report, too. You may pay using purchase orders or a major credit card. Please email or call at 630-839-9489
