China Air Cooler Water Defrosting Evaporator for Cold Storage - Reliable Suppliers & Factory Solutions

In the refrigeration industry, maintaining optimal temperatures is essential for preserving perishable goods, and a key component in achieving this is an electric defrost evaporating unit. Our Air Cooler is a versatile heat exchange solution, ideal for various cold storage applications, including high, medium, low temperature, civil cold storage, and combined cold storage, Manufactured in China, our water defrost Air Cooler uses a highly efficient system that utilizes warm water to melt accumulated frost on the evaporator coil. This process prevents clogging and ensures optimal operational efficiency. The water defrost mechanism activates at predetermined intervals or when frost levels reach a specific threshold. As warm water circulates over the evaporator coil, it effectively melts frost, allowing the unit to perform at peak efficiency, As a leading supplier and factory of refrigeration solutions, we are committed to providing high-quality products that meet the diverse needs of our clients in the cold storage sector. Choose our Air Cooler for reliable performance and efficiency in preserving perishable goods

Product Description

Product Description

Frequently Asked Questions (FAQ)
QWhat is the difference between W-SD, W-SL, and W-SJ series?
The W-SD series is for medium temperatures (-5°C to 5°C), W-SL is for low temperatures (-15°C to -25°C) such as meat and seafood freezing, and W-SJ is for ultra-low temperatures (-25°C to -40°C) used in quick-freezing.
QWhat refrigerants can be used with these coolers?
The W-series air coolers are compatible with multiple refrigerants, including R404A, R507A, and R22, providing versatility for various refrigeration systems.
QWhat installation types are available?
We offer both ceiling-mounted (Oblique, Standard, Double Side Blow) and floor-stand (Standard Top, Vertical Side Blow) options to suit different storage layouts.
QHow does the water defrost system save energy?
The system uses warm water to melt frost automatically. This method typically consumes less electricity than electric heating elements, reducing the overall operating costs.
QCan I customize the fan motor or fin type?
Yes. Options include MaEr or EBM fan motors and various fin materials such as light foil or blue hydrophilic aluminum foil to meet specific requirements.
QWhat evaporation area sizes are available?
The series covers a wide range from 30 m² up to 670 m². Please refer to the technical specification table for the full list of available sizes.
