Ammonia
91 articles 14 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

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:
Mitigating Liquid Trapping Risks in Ammonia Recirculation Pump Systems
By Kushal Aurangabadkar In industrial ammonia refrigeration systems, pumps play a vital role in circulating liquid ammonia to maintain cooling efficiency across evaporators and heat exchangers. The choice of pump type directly impacts system reliability, safety, and maintenance requirements. Among the most common options are conventional (mechanical seal) pumps and sealed (hermetic) pumps. Understanding their differences
