Eletrical Defrost Evaporator are cooling devices suitable for various large, medium, and small cold storage facilities (such as frozen food and storage preservation). The electric defrost air cooler comes in three forms: DL, DD, and DJ types, which are suitable for cold storage with different temperatures.
This series of products has the following characteristics:
○ Rational structure, even frost distribution, and high heat exchange efficiency;
○ The outer casing is made of high-quality steel plates, surface-coated for corrosion resistance, with an elegant appearance;
○ Special fan motors ensure low noise, large airflow, and smooth operation;
○ Stainless steel U-shaped tubular electric heaters with strong insulation properties are inserted into the fins, ensuring short defrosting time and excellent results;
○ The casing material can be customized using embossed aluminum sheets or stainless steel according to customer requirements;
○ The air cooler undergoes testing at 2.8 MPa pressure to ensure product stability during use.
