OEM Air Cooler Water Defrosting Evaporator for Cold Storage - China Suppliers | Quality Factory Equipment Manufacturer, Manufacturers

In the refrigeration industry, maintaining optimal temperatures is vital for preserving perishable goods. An electric defrost evaporating unit plays a key role in achieving this efficiency. Our Air Cooler is a versatile heat exchange equipment designed for various cold storage solutions, including high temperature, medium temperature, low temperature, civil cold storage, and combined cold storage, The water defrost Air Cooler utilizes warm water to efficiently melt the accumulated frost on the evaporator coil. This innovative system prevents clogging and ensures optimal performance. The water defrost mechanism is activated at specified intervals or when frost levels exceed a designated threshold. Warm water circulates across the evaporator coil, effectively melting frost and allowing the unit to function at peak efficiency, As a leading factory and supplier in China, we are committed to providing high-quality refrigeration solutions that meet the needs of our clients. Choose our Air Cooler for reliable temperature control and enhanced operational efficiency in your cold storage facilities

Why Choose Water Defrosting?

Water defrost air coolers are a cornerstone of modern refrigeration. By utilizing warm water instead of electrical heating elements, these units offer a more energy-efficient path to maintaining coil performance. This technology is vital for sectors ranging from pharmaceuticals to cold chain logistics, where product integrity and operational costs are top priorities.

⚡ Energy Efficiency

Designed to minimize power consumption by using water's thermal energy for defrosting.

🔄 Auto-Defrost

Hands-free operation ensures optimal performance without constant manual oversight.

🌡️ Precise Control

Advanced systems adjust cooling output to keep temperatures within strict ranges.

🛡️ Extreme Durability

Built with premium materials to withstand the harshest industrial cold environments.

Frequently Asked Questions

What is the difference between W-SD, W-SL, and W-SJ air coolers?

Each series targets a specific temperature range: W-SD is for medium storage (-5°C to 5°C), W-SL is for standard freezing (-15°C to -25°C), and W-SJ is for ultra-low temperature quick-freezing (-25°C to -40°C).

What refrigerants can be used with these units?

The W-series units are versatile and compatible with most common refrigerants, including R404A, R507A, and R22.

Are there different installation options available?

Yes. We offer ceiling-mounted versions with oblique, standard, or double-side blow, as well as floor-standing versions with top or vertical side blow.

Why is water defrosting considered more efficient?

Water defrosting typically uses less electricity than heating elements and can melt frost more evenly across the coils, reducing the downtime of the cooling cycle.

Can I customize the fan motor or fin material?

Absolutely. You can choose between MaEr or EBM fan motors and select from light aluminum foil, blue hydrophilic foil, or other specialty materials based on your environment.

What is the range of evaporating areas available?

The HT-WS series offers a broad range from 30 m² to 670 m². Custom configurations can also be discussed with our technical experts for specific project needs.
