Ammonia Refrigeration
92 articles 1 case study 15 insights
Ammonia has cooled industry for over a century, and the case for it keeps getting stronger: no global warming potential, high efficiency, low running cost. What holds it back is toxicity and the competence it demands. Refindustry follows the technology where it works hardest: industrial plants, cold stores, food processing and district cooling, with daily news, case studies and the engineers who r

Chillventa 2026 Preview: Key Technologies Ahead of the October Show
Exhibitors arriving in Nuremberg on 13 to 15 October are no longer arguing about whether to move to natural refrigerants. They are showing how fast the move can be made, and at what cost. That single change of question runs through nearly every release we have received ahead of Chillventa 2026, the largest edition of
Making Safety Visible: Kushal Aurangabadkar on the LOOP-BAR Framework for Ammonia Refrigeration
By Sergei Mukminov, Editor-in-Chief, Refindustry.com Industrial ammonia refrigeration facilities accumulate safety documentation over years: P&IDs, standard operating procedures, alarm lists, emergency plans and maintenance records. The problem is not that the information doesn't exist — it's that it lives in separate systems and rarely reaches the people making decisions on the plant floor. Kushal Aurangabadkar, an
Case Study – Effect of Louvers or diffusers on air flow distribution and cooling time on a meat log during Chill cycle
By Kushal Aurangabadkar An experimental analysis was conducted on a cooler space measuring 3.66 m × 6.096 m (12.0 ft × 20.0 ft), equipped with an ammonia refrigeration coil, five 30 cm (12 in.) fans, and five diffusers. The study measured airflow patterns, cooling rates, and heat transfer efficiency in meat storage by testing two configurations:
