IIAR’s Natural Refrigeration Conference & Heavy Equipment Show, an annual event that combines three days of exhibitions with a full conference program focused on natural refrigeration using ammonia and carbon dioxide, was cancelled on March 11 due to the worldwide pandemic, COVID-19.

According to a local report, Northwest Technical Institute held a groundbreaking ceremony for a 20,000 ft² facility that will be dedicated to an ammonia refrigeration and industrial maintenance program.

The Garden City Ammonia Program (GCAP) provides education for the industrial ammonia refrigeration operator for efficiency, safety and compliance. GCAP has several training opportunities available throughout March and April.

Greenyard Frozen has more than 50 years of experience in providing fresh-frozen fruits and vegetables. At its King’s Lynn production site in the United Kingdom — one of the company’s 10 sites across Europe — Greenyard Frozen needed a robust refrigerant leak detection and notification system. 

The design and installation of efficient temperature control within plant systems has been subject to relatively little innovation for decades. 

Learn about the recommended practices to manage the mechanical integrity of industrial ammonia refrigeration systems. This course, held November 6-8 at Pyle Center in Madison, Wis., will emphasize refrigerant piping and pressure vessels, but mechanical integrity practices for other components will also be presented.

Polyguard manufactures RG-2400, a gel product designed specifically for use on ammonia refrigeration piping to prevent CUI. Its relatively low level of surface preparation compares favorably with the installed cost of an epoxy paint, including the material and labor.

Model LBW-420-LEL is designed for catastrophic leak detection and response before the situation gets to the lower explosion level (LEL).
