OEM Electric Air Cooler Evaporator for Cold Storage - China Suppliers & Factory for Efficient Refrigeration Solutions Factories, Exporter

Refrigeration plays a vital role in our daily lives, with cold storage solutions being essential across various industries. To create an efficient cold storage system, one of the key components is the evaporating unit, commonly known as an Air Cooler. This heat exchange equipment can cater to a diverse range of cold storage applications, from high to low temperature environments.

Our Air Cooler / evaporator units are designed to deliver highly efficient cool air while effectively reducing frost accumulation on the fins, ensuring that cold storage environments operate optimally and that cooling energy use is minimal. These Air Coolers are available from reputable China suppliers and factories, featuring three distinct defrosting methods: electric, water, and hot fluorine, allowing flexibility to meet your specific refrigeration needs.

Product Description

Product Description

Our E-series electric defrost air coolers are divided into three series: E-DD, E-DL and E-DJ types, used differently as evaporators in medium temperature, high-temperature, and low-temperature cold storages.

E-D series electric defrost air coolers have compact structure, light weight, easy installation, fast air circulation in the storage, and it can balance storage temperature.

Product Application Ranges

The Air Cooler needs to be used with the refrigeration compressor unit. According to the required storage temperature, the corresponding air cooler should be selected.

🌡️ E-DL Series Suitable for cold storage with a storage temperature from -5°C to 5°C (23~41°F). Ideal for fresh foods, vegetables and other items.
❄️ E-DD Series Suitable for cold storage with a storage temperature from -15 to -25°C (5~-13°F). Suitable for freezing/refrigerated beef, mutton, fish, and seafood.
🧊 E-DJ Series Suitable for cold storage with a storage temperature of -25°C to -40°C (-13~-40°F). Mainly used for quick-frozen poultry, seafood, dairy products, etc.
