CA-788C-CR744 series carbon dioxide charging machine, can charge CO2 or other gas refrigerants. Due to charging mode of gas refrigerants is different from usual refrigerants, currently the rest of the world's manufacturer of cryogenic refrigerant filling accuracy is only 100g±5g. 788C-CO2 series adopt CACL subcritical condition charging technology, equip CA-6170 charging gun, make the charging precision up to 100g ≤ ±2g, 100g outside≤ ±2%, raise the industry standard greatly.
