An FNU Condenser is a specialized box-type cabinet air-cooled heat exchanger. It is designed to dissipate heat efficiently in commercial and industrial refrigeration systems. By utilizing Freon-based air convection, this highly efficient unit extracts heat from refrigerant gas. It then releases this heat into the surrounding atmosphere to ensure stable refrigeration cycles. Designed with a compact structure, this condenser is ideal for cold rooms ranging from 10 to 500 square meters. Its space-saving footprint is critical for facilities with restricted outdoor areas. You can easily place it on rooftops, tight side yards, or outdoor platforms. Unlike basic component suppliers, HELENG provides complete design synergy. We ensure these heat exchangers are fully optimized for your parameters as part of our one-stop cold storage services.
Selecting the correct FNU Condenser specification is critical to maintaining high energy efficiency. Proper sizing also ensures system balance in your cold chain infrastructure. Our HELENG XBU/FNU series is engineered to match a wide range of operational requirements. This guarantees optimal heat transfer across diverse climates. Below is the technical breakdown of our standard models. We can further customize these specifications during the project planning phase.

|---|---|---|---|---|---|
| HELENG FNU-12 | 12.5 | 1 | 400 | 4,200 | 780 x 420 x 680 |
| HELENG FNU-25 | 25.0 | 2 | 400 | 8,400 | 1150 x 420 x 780 |
| HELENG FNU-40 | 40.0 | 2 | 500 | 12,500 | 1350 x 480 x 950 |
| HELENG FNU-75 | 75.0 | 3 | 500 | 18,800 | 1950 x 520 x 1100 |
At HELENG, we prioritize mechanical precision and material integrity. This helps us deliver refrigeration components that stand the test of time. Our condenser line is manufactured under strict quality control standards. We build them in our modern production facility to guarantee peak thermodynamic performance and reduce your operational overheads.
The internal architecture of our heat exchangers utilizes high-purity φ9.52 copper tubes. These are paired with advanced hydrophilic aluminum fins. This configuration maximizes the overall heat exchange surface area while facilitating rapid condensate runoff. As a result, you gain up to a 30% increase in heat transfer efficiency compared to legacy models.
Airtightness is paramount in critical cold chain storage applications. This includes pharmaceutical warehouses, electronics manufacturing, and food logistics. To prevent refrigerant leaks, every unit undergoes an exhaustive 2.8Mpa nitrogen pressure test. We perform this evaluation before the equipment leaves our factory floor. This ensures zero-leakage durability under high-pressure operations.
These units feature a practical cabinet-style frame and an upward-facing top-discharge design. This engineering choice allows for versatile outdoor installation. The top-discharge configuration directs hot exhaust air straight up. This makes close-wall installations in narrow corridors possible. Additionally, the casing is fabricated from weather-resistant, sprayed galvanized steel plate. This finish protects core components from corrosive industrial and coastal environments.
Our condensers are equipped with high-performance external rotor fan motors. This helps facilities comply with strict urban noise regulations and environmental guidelines. These specialized fans run quietly while delivering stable, high-volume airflow. They operate with minimal power draw, striking a perfect balance between acoustic compliance and thermal efficiency.
HELENG distinguishes itself from simple wholesale distributors. We offer perfectly engineered refrigeration assemblies rather than just individual parts. Our FNU Condenser units are carefully mapped and pre-sized. We integrate them with industry-leading compressor brands, including Fusheng, Bitzer, and Heron systems. This exact engineering calibration guarantees precise system balance. It also eliminates costly field-matching errors during installation while optimizing the total energy footprint.
HELENG operates a state-of-the-art intelligent manufacturing base in Shanghai covering more than 5,000 square meters. We are backed by the substantial resources of our parent company, the Luohe Tian Shun Cold Chain Group. Our technical capabilities extend far beyond component manufacturing. We deliver comprehensive turn-key cold storage projects. From initial cold room planning and thermal calculations to custom OEM configurations, we handle it all. As your dedicated cold chain partner, we also manage final delivery, site installation, and system commissioning.
HELENG offers the inventory and manufacturing flexibility to meet your tightest project deadlines. We support commercial cold storage contractors, OEM equipment buyers, and cold chain logistics providers. As a premier FNU Condenser manufacturer, we provide flexible wholesale options and low minimum order quantities. We also ensure reliable international dispatch for our global clients. To receive a custom system-sizing consultation, please contact our team. You can discuss your exact project specifications and get a competitive quotation. Our engineering support staff is available 24/7 to assist you.
Our FNU box-type cabinet condensers are engineered for high compatibility. They seamlessly integrate with top compressor brands, including Bitzer, Fusheng, Heron, and Copeland. We ensure each pairing matches your exact heat dissipation requirements.
Every unit undergoes a rigorous 2.8Mpa air pressure airtightness test in our Shanghai manufacturing plant. This exhaustive process ensures complete system sealing. As a result, our units are highly reliable for sensitive applications like pharmaceuticals and food logistics.
Yes. We operate a 5,000-square-meter intelligent manufacturing base with an experienced R&D team. This allows us to offer comprehensive OEM and ODM custom sizing. We can adjust fan quantities, provide low-noise options, and apply specialized anti-corrosion coatings.
The top-discharge cabinet structure directs hot air upward rather than outward. This smart design allows you to install the condensing unit in narrow corridors. It is also ideal for placement next to walls or in compact outdoor spaces where side airflow is restricted.
