For refrigerated and frozen food processors, choosing between an ammonia or an ammonia/CO2 cascade system can be one of the most important variables.
One of the primary drivers when evaluating ammonia or ammonia/CO2 cascade systems is understanding that ammonia contamination in processing and production rooms can be a huge potential liability to facilities and dangerous to employees. Associated with this liability is a second key concern—the threshold quantity (TQ) of 10,000 pounds for ammonia charge, as stated by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) programs.
