An air-cooled condensing unit is a pre-packaged refrigeration system that integrates a compressor, an air-cooled condenser, a fan, a liquid receiver, and safety controls into a single assembly. This design expels heat through a fin-and-tube coil and axial fans, allowing the refrigerant to condense without the need for a water pump or cooling tower.
This technology provides stable, low-vibration cooling essential for freezer rooms, food processors, pharmaceutical facilities, and industrial process cooling. Whether you require indoor air-cooled condensing unit installations or robust outdoor units, this technology offers simple integration and reduced maintenance.
Advantages of Air-Cooled Condensing Units
Our product range includes wall-mounted mini boxes, box-type condensing units for U/V/H configurations, open-type systems, and high-capacity screw or parallel compressor units.
No Cooling Tower Required: The air-cooled design uses fans to dissipate heat, eliminating the cost, water consumption, and maintenance associated with cooling towers. The unit should simply be installed with sufficient airflow to maximize heat exchange.
Simple Installation: The system is shipped as a pre-assembled package with the compressor, condenser, and controls. Many models include a pre-wired control panel, simplifying installation to mounting, electrical connection, and commissioning.
Wide Temperature Range: Our units support evaporation temperatures from -60°C to +15°C, covering high-temperature (+12°C) fresh-keeping chambers, medium-temperature ( -23°C) chilled storage, and low-temperature ( -40°C) freezing.
Energy Efficiency & Sustainability: We integrate high-efficiency scroll, semi-hermetic reciprocating, and screw compressors from world-class brands. Features like hydrophilic fin coatings and inner spiral copper tubes improve heat transfer, delivering significant energy savings compared with traditional systems.
Low Noise & Vibration: Scroll and screw compressors have fewer moving parts, resulting in reduced noise and vibration, making them suitable for environments with sensitive instrumentation.
Reliability & Safety: All units undergo pressure testing and leak detection. High/low-pressure protection, compressor overload protection, and specialized components (oil separators, accumulators) safeguard the system and ensure continuous operation.
Environmentally Friendly Refrigerants: Standard models use R404A and R507A, with options for R22 or R134a.
Box Type Air-Cooled Condensing Units
Box-type units offer a fully enclosed, weatherproof package, ideal for outdoor or exposed installations.
Wall-Mounted Mini Box (2–10 HP): Ideal for limited-space installations where noise must be minimized. Features a slim profile and sideward air discharge. Supports evaporation temperatures from -40°C to +12°C for versatile storage needs.
U-box & V-box Condensing Units (2–50 HP): These ranges package all components into a robust unit, popular with cold-chain logistics centers and convenience stores. The all-in-one design protects components, and the U- or V-shaped condenser fins ensure efficient heat dissipation.
H-box Units (Side-Blow): Provides a rapid-cooling, all-in-one design with side-blow fans for narrow installation spaces or facility retrofits where airflow path is restricted.
The open-type air-cooled condensing unit uses an exposed frame, making each component fully accessible for commissioning and maintenance.
Flexibility: The open structure allows separate installation of the condenser and compressor module, which is useful when the complete set is too large for container shipping or when lifting restrictions apply.
Reliable Performance: Features high-quality fans, a large liquid receiver with a safety valve, and robust protection devices.
Compressor-Specific Condensing Units
Designed for medium to low loads, the scroll compressor offers rapid refrigeration and quiet operation. With 70% fewer moving parts than reciprocating compressors, it provides lower vibration and sound, suitable for medium-high temperature cold rooms, fruit/vegetable storage, and walk-in freezers.
When maintenance and reliability are paramount, semi-hermetic designs allow servicing of internal components. These units deliver high cooling capacity and low energy requirements, ideal for meat and seafood storage, frozen food logistics, and industrial process cooling.
For large cold storage facilities or process cooling requiring capacities up to 160 HP, the screw compressor unit offers high efficiency and reliable operation. Features include:
Smart Control: Integrated PLC and HMI ensure reliable operation, manage defrost cycles, and provide fault diagnostics.
Energy Regulation: Available in four-stage or infinite modes, allowing output to precisely match varying load demands.
Large cold rooms and logistics warehouses benefit from parallel compressor condensing units. Multiple compressors provide multi-level output and smooth energy adjustment. This configuration offers redundancy, ensuring that if one compressor fails, the others continue to run, maintaining system reliability.
Applications Across Industries
Our air-cooled condensing unit range is widely used in:
Cold Storage & Logistics: Fruit and vegetable storage, meat and seafood freezing, pharmaceutical warehousing, and general logistics cooling.
Food Processing & Retail: Managing walk-in coolers, freezers, and display cases in supermarkets, restaurants, and processing plants.
Chemicals & Laboratories: Providing stable temperature control for industrial reactors and test chambers.
Marine & Offshore: Screw compressor systems with marine-grade components and enlarged condensers designed to withstand harsh environments.
How to Choose the Right Air-Cooled Condensing Unit
Choosing the right unit involves balancing capacity, efficiency, and design features:
Define the Load and Temperature Range: Determine the required refrigeration capacity (HP or kW) and the necessary evaporation temperature range.
Choose the Compressor Type: Small systems (2–10 HP) use scroll; medium (10–50 HP) often use semi-hermetic reciprocating; large applications (30–150 HP) may require screw or parallel compressor units.
Decide on Box vs. Open Structure: Box-type units offer weatherproof protection and easier outdoor installation. Open-type condensing unit solutions provide accessibility for maintenance and allow flexible component arrangement.
Consider Energy Efficiency & Noise: Look for features like hydrophilic fins, copper tubes, and variable fan speed control for maximum efficiency.
We offer a wide range of high-quality products for refrigeration, which are widely applied in many industries such as food, marine, medicine, chemical, workshop, distribution center and logistics.
