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.
Commercial refrigeration are now moving to use carbon dioxide as their choice for refrigerant gas, due to its low global warming potential. However CO2 is a toxic gas under UK COSHH and US OSHA regulations. This means you need to have systems in place to monitor for any Co2 leaks. Importantly those visiting commercial refrigeration sites need to protect themselves from the toxic effects of CO2. Our article addresses this issue and why you need a portable CO2 detector and our iGAS CO2 portable monitor.
