Refrigeration Evaporator Designed for storage of fruits, vegetables, dairy products, and dry goods at temperatures between 0℃ and 10℃, this Cold Room Evaporator features high airflow and low resistance, controlling temperature drift within ±0.5℃ to prevent localized over freezing or accelerated spoilage due to temperature rise. The wide blade fan provides gentle airflow coverage, reducing moisture evaporation, minimizing dryness loss, and extending shelf life. Intelligent dual defrosting logic (time + temperature) avoids ineffective defrosting and temperature rebound. The shell is rust-proofed, and the drainage channel prevents water accumulation and bacterial growth. Stable preservation while saving considerable monthly electricity costs makes it an ideal partner for medium-temperature storage.
