2025 USE CASE Enhanced Ammonia Gas Bank Safety System with LoRaWAN ® : From Risk to Resilience A leading watch manufacturing company in India faced significant safety concerns in ammonia gas handling, where manual cylinder operations led to safety threads, which also led to poor product quality and increased downtime. SITUATION In a manufacturing industry, ammonia (NH3) gas is a critical component in the annealing process. However, leakage in the ammonia gas bank presents a significant risk to human safety and the environment. The company required an automated, reliable and scalable system to monitor and control ammonia gas usage and to enhance safety while reducing manual intervention and process downtime. ISSUE The legacy system relied heavily on manual operations for cylinder switching and monitoring, resulting in: • Lack of Real Time Monitoring: Depending on manual monitoring leads to delayed addressing of issues and leads to safety incidents. • Ammonia Gas Leakage: Leakage of ammonia creates major safety issues and environmental contaminations. • Lack of Automatic Control System: Relying on human intervention during ammonia leaks create threats to the human life. • Delayed Switching of Cylinders: Unawareness of the cylinder being empty leads to reduced gas input to the process thus creates poor product quality and increases wastage. • Unaware of Cylinder Utilization: No proper analysis and utilization of gas cylinders leads to wastage of gases. These challenges were obstructing effective safety management and optimal gas usage. COMPANY CONTACT INFO Enthu Technology Solutions India Pvt. Ltd. https://iot.enthutech.in/industry/ iot@enthutech.in SOLUTION With the advancements of LoRaWAN, Enthutech created a comprehensive solution to enhance the Gas Bank Safety and Control. Our solution offers: • Real-time Monitoring: Continuous monitoring of gas cylinder presence, lock position, and pressure enables the user to be aware of the gas banks operation. • Leakage Detection: Using automatic leakage detection, the system automatically shuts off the control valve, activates a water curtain to neutralize the gas, and triggers both physical and remote alarms. • Automated Cylinder Switching: Automatically switches to the standby cylinder when the active one is empty, with no manual intervention. Thus, reduces the downtime and reduces product waste. • Cylinder Analytics: Our smart AI powered thingZmate ® platform provides effective analytics to utilize the cylinder in an efficient way so that the wastage of gas is reduced. Solution Outcome: Ø Zero safety incidents regarding ammonia leakage. Ø 23% reduction in production wastage Ø 75% decrease in downtime related to cylinder changeover Ø 30% reduction in gas wastage Ø Scaled the solution for 150 gas cylinders throughout the campus using LoRaWAN â Industry India Solution
