Winter 2022 - Engineering Safety Relief Systems course

Whether you are an end-user, equipment manufacturer, design engineer, or contractor, this webcourse will help you build your capabilities in the area of the principles and practices of engineering safety relief systems. Attendees receive access to the IRC’s web-based safety relief systems analysis tool (Ver. 2.0) for a three-year period. The tool has a high degree of flexibility to analyze, engineer, and document safety relief systems for industrial refrigeration applications.

Machinery Room Ventilation Calculation Tool Update

The Machinery Room Ventilation Calculation Tool spreadsheet has been updated to Version 2.40. IIAR 2-2021 is now incorporated and a tab to account for additional machinery room heat loads has been added. Thanks to Ron Worley for his efforts in creating the tool and making the new version.


The Industrial Refrigeration Consortium is a collaborative effort between the University of Wisconsin Madison and corporations. Our goal is to improve the safety, efficiency, and productivity of industrial refrigeration systems and technologies. We realize this goal by conducting applied research, delivering knowledge transfer, and providing technical assistance. Although our efforts are focused on industrial refrigeration systems that utilize anhydrous ammonia, we also work with systems that use other refrigerants.

The IRC offers a unique combination of complementary resources that include academic qualifications, technical expertise, and practical experience. We provide objective information that is not biased by an affiliation with any particular organization.
