Commercial Refrigeration products can be very diverse in terms of size, refrigerant type and charge weight. Production equipment flexibility becomes a key factor in this market. Productivity is typically low to medium and in some instances allows the integration of additional functions, such as leak testing and pre-evacuation, within the refrigerant charging equipment. Typical refrigerants include R134a, R404a, HFO Blends (e.g. R448), and R290 (Propane).
