Walk-in freezer repair — designed to freeze products at temperatures between -18°C and -25°C. They require thick insulation (12-15 cm) and powerful defrost systems. Call **16062** to protect your frozen stock.
Walk-in freezers rely on powerful low-back-pressure compressors and electric defrost systems that clear ice from the coil every 6 hours. Common faults include defrost heater burnout, evaporator fan icing up, and a failed door heater.
