Zero Zone CO2 Technician Training

A comprehensive in-person program from Zero Zone, one of the manufacturers REFPRO represents, designed to equip technicians to work with CO2 refrigeration: installation, maintenance, troubleshooting and safety.

Why CO2 Training

Higher Pressures, Different Rules

CO2 systems are increasingly favored for their low global warming potential and natural properties. Working with CO2 requires specific knowledge and skills, since it operates at higher pressures and behaves differently than traditional HFC refrigerants.

What the Course Covers

Understanding CO2 properties
Subcritical and transcritical CO2 systems
Familiarization with CO2 components
Piping techniques
Oil level controls
Safety protocols and servicing procedures
Start-up procedures

The training concludes with a review and a quiz to assess comprehension and competency.
