Status: Final Directive Published

The newly adopted CSA B52:23 Mechanical Refrigeration Code incorporates specific requirements for secondary coolant systems that were previously included in safety order SO-BP 2021-01. Since these requirements are now broadly addressed within the code, we will replace this safety order by a new directive which aims to:

• address the application of secondary coolant overpressure protection requirements, including documentation requirements when the chosen approach includes monitoring or process management elements;

• clarify testing and maintenance requirements for secondary coolant systems, including test objectives/capabilities, testing frequencies, reporting, records retention, and continual monitoring for refrigerant leakage.

To support continued collaboration with the refrigeration industry, we would like to invite industry experts to review the draft directive linked below, then share your feedback by answering a short survey. Your feedback will help shape the final directive.

Survey: Secondary coolant systems

We invite your feedback on a draft directive which aims to clarify expectations for refrigeration systems with a secondary coolant. Before responding, please read the draft draft directive on the engagement page. This survey should take between 5-10 minutes and is intended for refrigeration plant owners, chief engineers, power engineers, operators and other individuals in charge.

The information collected in this survey is in accordance with our privacy policy(External link). Results will be reported as a whole.
