Ammonia presents high efficiency in freezing food products for preserving them for exportation; however, the use of this refrigerant implies a high risk to human life because it presents high concentrations of toxic gases that can produce deadly consequences to human beings. Smart relays present a flexible manner to automate industrial process; therefore, this poster aims to replace the manual and inefficient manner of controlling ammonia cooling system by using a smart relay that can control the levels of this refrigerant in the precooler and cooler section; resulting in considerable decrease workers’ in exposure to this refrigerant.
