Technical Specifications OverviewCooling System: Direct Cool / Frost System. This system requires manual defrosting over time using a built-in defrost mechanism or an included ice scraper.Refrigerant: Typically uses older R-134a or early environment-friendly R600a isobutane gas.Electrical Needs: Standard 220V–240V / 50Hz operation. Due to its older mechanical compressor design, it functions best when paired with an external manual voltage stabilizer to protect against local power fluctuations.Storage Ratio: Built with a standard 45:55 or 40:60 space compartment ratio, splitting the interior capacity efficiently between a top-mounted freezer section and a lower fresh-food compartment.
