-50 to -70℃! This is a freezing system equipped with a complete defrosting device built into the def and mac.
The "Mac 2-Stage Low Temperature Freezer Unit" establishes -75°C evaporation and achieves complete defrosting without a heat source through an innovative hot gas defrost system. The hot gas defrost system has significant energy-saving effects, leading to reduced electricity and running costs. No other heat source is required. Due to its intense heating capability, the quick defrost feature shortens defrosting time, thereby minimizing temperature rise inside the freezer. 【Features】 ■ The dual-stage refrigeration unit exhibits ultra-low temperature, high-efficiency refrigeration capability. ■ The cycle self-generated hot gas defrost method completely melts ice from the evaporator. ■ The temperature control inside the freezer has a wide range from -50°C to -70°C. ■ The defrost method using the refrigeration cycle eliminates the need for electric heaters or other heat sources. *For more details, please refer to the PDF document or feel free to contact us.
