Large-scale refrigeration systems are an integral part of many industries, such as cold storage, petrochemical refining, and food processing. In such applications, Ammonia is the most common choice of refrigerant due to its effective physical properties and low freezing point, making it perfect for refrigeration uses. As ammonia is extremely dangerous to life and health at a concentration of 25ppm (8hrs) and 35ppm (15 minutes), it is critical for ammonia gas detectors to be used in such applications to maintain the safety of the plant and those in the vicinity.
Cold room units (or walk-in freezers) are an integral part of the food and beverage processing industries. Typical refrigerant gases include carbon dioxide, ammonia, and hydrocarbons such as propane, isobutane and propylene. Older cold storage solutions still use freon gases such as R134a. Thus, a versatile range of gas detection solutions are required for cold storage applications.
