A company that develops and produces generic drugs such as ear drops, scalp & body oils, liquid syrup, oral solids, nasal sprays & more chose Control Instruments' PrevEx Flammability Analyzers over IR sensors to monitor the flammability of the batch oven exhaust streams going into the oxidizer. 

The Process

The pharmaceutical process involves coating products with a mixture of solvents (IPA, ethanol & acetate) and then heating them in batch ovens. The solvents evaporate off in the heating process and are collected and fed into a main duct that feeds into the thermal oxidizer for destruction.

The Challenge

NFPA 86, the National Fire Protection Association's Standard for the Safe Operation of Ovens and Furnaces defines direct-fired thermal oxidizers as Class A Furnaces mandating the use of continuous Flammability Analyzers on inlet streams exceeding 25% LFL. The analyzer’s job is to activate warning and danger alarms before the inlet stream reaches 50% LFL. This can save the oxidizer from destruction by fire or explosion. Operation above 50% LFL is not permitted.

They chose Control Instruments' PrevEx Flammability Analyzers over IR sensors to monitor the flammability of the batch oven exhaust streams going into the oxidizer.
