Features
Technical Data
Massive box-type heat exchange technology engineered for medium-to-large industrial refrigeration environments.

The FNU Box Type Heat Exchanger combines a robust cabinet structure with high-capacity thermal rejection. Designed for flexibility in both indoor and outdoor installations, it ensures precise temperature control for cold storage, HVAC systems, and high-traffic retail environments.

Industrial & Commercial Applications

Large Cold Storage

Ideal for facilities storing fruit, seafood, and meat (0°C to -25°C), supporting capacities like the FNU-1200 (32.1kW rejection).

Supermarket & Retail

Maintains precise 2-8°C or -18°C tiers for display cases, fitting seamlessly into limited rooftop or rear alley spaces.

Food Service & Restaurants

Provides ultra-quiet, high-efficiency cooling for walk-in units, preserving food quality without disrupting customer environments.

Industrial HVAC

Delivers stable heat rejection for complex building cooling systems where long-term durability is a critical requirement.

Massive Heat Rejection Capacity

Engineered for high-load systems, with models like FNU-800 delivering 22.4kW and FNU-1200 reaching 32.1kW rejection.

High-Pressure Sealing (2.9MPa)

Every coil unit undergoes 2.9MPa air-tight testing, ensuring a zero-leak system that significantly reduces annual maintenance costs.

Whisper-Quiet Operation (< 60dB)

Equipped with internal rotor blowers delivering high airflow (7000m³/h) while maintaining noise levels below 60 decibels.

✔ Robust Cabinet-Type Structure

Massive box design provides superior protection for internal components and offers an aesthetic, space-saving industrial footprint.

✔ Advanced Mechanical Expansion Coils

High-quality copper pipes and fins are mechanically expanded for a perfect tight bond, maximizing thermal exchange efficiency.

✔ Customizable Anti-Corrosion Protection

Standard coated shells with stainless steel options available for extremely harsh coastal or chemical factory environments.

✔ Versatile Deployment Options

Customizable colors for brand integration and adjustable fan configurations to meet specific noise or airflow project constraints.

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.
