What type of equipment can a technician work on with a Type III certification?

A technician with a Type III certification is specifically trained to work on low-pressure appliances. This certification is designed for those who handle refrigerants in the context of systems that operate below a certain pressure threshold, which typically includes chillers and other similar equipment. Low-pressure systems have unique operational characteristics and safety considerations that differ from medium- and high-pressure systems, which require different types of certifications.

In this context, the focus on low-pressure systems is crucial because it encompasses understanding the specific refrigerants used in such systems, their handling requirements, and the related environmental impacts. This specialization ensures that technicians can competently and safely manage the maintenance and repair of low-pressure refrigerant systems.
