Overview
Advantages
Features
Technical Data
Versatile Water Defrost Air Coolers engineered for high-performance Freon refrigeration systems.

The SDL, SDD, and SDJ series provide precise temperature control across all cold storage tiers. Featuring a robust, corrosion-resistant design, these units ensure stable cooling for the cold chain, food processing, and pharmaceutical sectors.

Core Industrial Applications

Cold Chain & Warehousing

Maintains stable -18°C/-0.4°F for frozen meat and seafood, preventing frost damage through uniform thermal distribution.

Quick-Freezing Processing

The SDJ series rapidly cools products to -25°C/-13°F, preserving freshness while maximizing production uptime.

Pharmaceutical Storage

Fully GMP-compliant cooling for vaccines and reagents, ensuring exact temperature stability for sensitive medical supplies.

Textile & Chemical

Effective moisture and heat control to prevent deterioration of raw materials in specialized low-temperature storage.

Smart Energy Saving Defrost

Advanced water and electric defrost distribution shortens cycles by 30%, drastically cutting operational energy consumption.

Superior Long-Term Durability

Premium treated steel shells and copper-tube bonding offer exceptional longevity of 15+ years in humid industrial environments.

2.5MPa Leak-Free Assurance

Rigorous high-pressure testing ensures zero leaks, protecting the system's refrigeration efficiency and lowering long-term maintenance costs.

✔ High-Efficiency Heat Exchange Coils

Premium copper tubes with mechanical expansion maximize the evaporation area (e.g., SDD-12/60 model delivers 12kW at -18°C).

✔ Advanced Shell Customization

Optional embossed aluminum or stainless steel shells for extreme corrosion resistance in the most demanding industrial settings.

✔ Versatile System Compatibility

Full support for both standard fluorine pump systems and specialized ethylene glycol refrigeration requirements.

✔ Specialized Air Ducting

Available with long-type air supply ducts and specialized designs for ultra-low temperature rooms (below -35°C/-31°F).

Are you a manufacturer?

Yes, we bring over 10 years of professional expertise to the refrigeration industry. Our manufacturing facility is located in Jinhua, Zhejiang Province, China. We warmly welcome you to visit our factory and witness our meticulous production process firsthand, from the initial stages to the final product.

Can you recommend a customized solution for our specific project?

Absolutely. We are more than just a manufacturer; we are a team of experts dedicated to providing comprehensive cooling solutions. We understand that every project has unique operating conditions. To ensure the most efficient and reliable performance, we prioritize understanding your specific requirements first, allowing us to analyze and recommend a tailored solution that fits your needs perfectly.

How to install machinery on-site? Will you arrange engineers for overseas services?

We typically provide comprehensive installation drawings and user manuals for all equipment. Our team offers remote technical support to guide you through the installation process. Should you require on-site service from our engineers, please feel free to contact us to make arrangements. However, rest assured that with the provided installation documentation and our online guidance, most installations can be successfully completed without the need for on-site assistance.

What are the warranty and after-sales service details for your machines?

All our machines come with a one-year warranty from the date of customer receipt. In the event of quality issues, we will provide replacement parts free of charge. However, shipping costs for these parts will be the customer's responsibility. After the one-year warranty period, all associated costs will be borne by the customer.

What should we do if we encounter technical issues during installation?

Every unit undergoes rigorous operational testing under real-world conditions before leaving our factory. We only authorize dispatch once performance is 100% verified. To simplify your setup, all components come pre-installed—you only need to connect the external piping to begin operation. If you encounter any challenges during installation, rest assured: since the system was pre-verified, most issues are simply minor connection errors. Should this happen, just hop on a video call with us, and our engineers will provide step-by-step guidance to get you up and running.

How often do I need to perform routine checks and maintenance cycles?

As maintenance intervals vary depending on the specific model and its operating conditions, we provide a customized inspection and service schedule as part of every tailored solution. This ensures you have a clear roadmap for routine upkeep to keep your system running at peak efficiency.
