Which type of equipment can be serviced with a Type III certification?

A Type III certification is specifically designed for technicians who will be working with low-pressure systems, which are defined as those that operate with a refrigerant that has a low boiling point. Low-pressure systems typically include appliances that use refrigerants like R-11 and R-123, which operate below atmospheric pressure.

The certification enables technicians to safely handle, recover, and dispose of refrigerants in these systems while following federal regulations. Understanding the unique characteristics of low-pressure systems is crucial for ensuring proper service and compliance with environmental laws.

Though other types of equipment, such as high-pressure and medium-pressure systems, require different certifications, Type III is focused on low-pressure applications. This distinction in certification levels is important as it ensures that technicians are adequately trained and knowledgeable about the specific requirements, risks, and safety protocols associated with servicing low-pressure refrigeration systems.
