Industrial Refrigeration Plant Tour: From R22 to Natural Refrigerants

ASHRAE Southern California Chapter

See how Jessie Lord Bakery successfully transitioned to natural refrigerants while increasing cooling capacity and advancing sustainability.

Jessie Lord Bakery

Join us on May 1st for an exclusive technical tour of the newly converted refrigeration plant at Jessie Lord Bakery, featuring a state-of-the-art low-charge R717/R744 (Ammonia/CO₂) cascade system.This facility recently transitioned from a legacy 55,000 lb R22 refrigeration system to a modern natural refrigerant solution utilizing approximately 9,000 lbs of ammonia (R717) and 9,000 lbs of CO₂ (R744) — while simultaneously increasing overall cooling capacity. The project represents a significant step forward in sustainability, refrigerant risk mitigation, and high-efficiency industrial refrigeration design. <h3>Tour Schedule</h3>Two sessions available:<ul><li>9:00 AM – 9:45 AM</li><li>10:00 AM – 10:45 AM</li></ul>Attendance is limited to 20 participants per tour to ensure safety and an engaging experience.

<h3>Tour Highlights</h3>Participants will visit:<ul><li>Compressor Engine Room</li><li>Control Room</li><li>Equipment Roof Level</li></ul>Attendees will gain insight into:<ul><li>Low-charge ammonia system strategies</li><li>CO₂ cascade integration</li><li>System design considerations for industrial bakeries</li><li>Operational and safety considerations</li><li>Lessons learned from large-scale refrigerant conversion</li></ul>

<h3>What to Wear / Prepare</h3><ul><li>Safety Vest: Encouraged (please bring your own if available)</li><li>Safety Helmet: Not required</li><li>Safety Shoes: Not required (facility is not under construction and no slippery surfaces are anticipated)</li></ul>
