What refrigerants are typically found in Type III systems?

Type III systems are specifically designed for the recovery, recycling, and reclamation of refrigerants from appliances and equipment that are considered low pressure, such as chillers and specific industrial systems. These systems often use high-pressure refrigerants, which is why the answer highlights them as the refrigerants typically found in Type III applications.

High-pressure refrigerants are those that operate at pressures exceeding 15 psig at 0°F. Understanding this is crucial for technicians working with refrigerant recovery. The use of high-pressure refrigerants in these types of systems necessitates specialized techniques and equipment for safe handling, as improper management can lead to safety hazards and compliance issues with EPA regulations.

Other options include low-pressure refrigerants, which are not typically part of Type III systems focused on high-pressure appliances, as well as non-flammable and natural refrigerants, which may not specifically pertain to the characteristics of Type III refrigerants. Thus, the emphasis on high-pressure refrigerants is essential for anyone preparing for the Type III EPA 608 Certification.
