Evaporative Condenser Manufacturers

The operating principle of the evaporative condenser is similar to that of a conventional closed cooling tower. The difference is that the conventional closed cooling tower inlet heat medium and the tower outlet cooling medium are both liquid and have only temperature changes, while the evaporation condenser inlet heat medium is gaseous and after the tower outlet is discharged, the medium is condensed into liquid. Evaporation condensers are products that combine cooling towers and condensers.

Advantages of evaporative condenser:

High-efficiency condensation: evaporative cooling is used to reduce the condensation temperature by 10% to 30%.

Water saving and electricity saving: Save 30% to 50% water saving than traditional water cooling tower + shell and tube condenser, saving the energy consumption of the cooling tower.

Compact design: Integrated condensation + cooling function to reduce footprint.

Strong adaptability: suitable for high-temperature and arid areas (relying on wet bulb temperature rather than dry bulb temperature)

Advantages of Fangnuo evaporative condenser:

● Parallel air flow and water flow minimize the appearance of "dry points" at the bottom of the cooling pipe that cause scaling;

● The coil section dissipates heat by evaporative cooling induced by the flowing fresh air, and on the other hand, it dissipates heat by heat transfer cooling of the spray water. Reducing the evaporative cooling portion of the coil section helps to reduce the possibility of scaling on the surface of the coil;

● Spray water with a min. flow rate of 6.8L/S/㎡ is evenly distributed to the surface of the coil through the spray system to ensure that the surface of the cooler coil remains continuously wet, thereby improving the heat conduction efficiency and reducing the scale to a minimum;

● The spray water falls from the cooling coil to the heat exchange layer of the PVC filler, and is cooled on the PVC filler with the second stream of fresh air entering the tower through evaporation and heat conduction (latent heat and sensible heat), so that the spray water is cooled secondaryly and the spray water temperature is further reduced;

● The secondary cooling circulating water increases the temperature difference between the spray water and the process hot fluid, increases the heat exchange efficiency of the cooling coil, and reduces the number of coils required. This characteristic further alleviates the tendency of scaling on the surface of the coil, because the lower the spray water temperature, the less likely it is to scale. In addition, due to the small number of coils used, the cost of replacing coils in the later stage is reduced and the maintenance cost is lower;

● The operating cost is low, and it is more energy-saving than conventional cooling cycles;

● The circulation system is simpler and reduces the installation cost of the circulation system;

● It saves more equipment installation space than conventional cooling circulation systems.

Differences Between Evaporative Condensers and Closed Cooling Towers

Both evaporative condensers and closed cooling towers play vital roles in industrial cooling and refrigeration systems. While they share a similar principle—removing heat through air and water circulation—they differ in their working medium, heat transfer process, and energy efficiency. Understanding these distinctions helps users choose the most suitable solution for their system requirements.
1. Working Principle: Condensation vs. Liquid Cooling
The main difference lies in the state of the working fluid.
A closed cooling tower cools a circulating liquid such as water or glycol. The fluid’s temperature drops, but it remains in the liquid phase.
An evaporative condenser, however, handles a gaseous medium—like refrigerant vapor—which is cooled and condensed into a liquid inside the coil. This combines the roles of both condenser and cooling tower, enabling more efficient heat exchange.
At Fangnuo Heat Transfer System (Jiangsu) Co., Ltd., engineers optimize this phase-change process, ensuring high condensation performance and stable system operation through precise water and air distribution designs.
2. Heat Transfer Efficiency
In a closed cooling tower, heat transfer occurs mainly by convection and limited evaporation.
An evaporative condenser achieves higher efficiency because the refrigerant gas releases heat while the spray water and air provide both evaporative and sensible cooling. This lowers the condensation temperature by 10%–30%.
Fangnuo’s design adopts parallel air and water flow to prevent dry spots and uniform spray systems that keep coil surfaces wet, enhancing heat transfer and reducing scaling.
3. Energy and Water Consumption
Evaporative condensers are typically more energy- and water-efficient than traditional systems. By integrating condensation and cooling into one process, they can save 30%–50% more water and reduce fan and pump energy use.
Fangnuo further simplifies the circulation system, cutting installation costs while maintaining strong cooling capacity. The design’s reliance on wet-bulb temperature also makes it effective in hot and arid environments.
4. Structure and Maintenance
Closed cooling towers usually require external condensers and more piping space. Evaporative condensers combine multiple functions in a compact structure, minimizing footprint and maintenance needs.
Fangnuo incorporates a PVC filler layer for secondary cooling, which lowers spray water temperature and further reduces the risk of scaling. Fewer coils are required, leading to lower replacement and maintenance costs.
5. Application and Industry Use
Closed cooling towers are suitable for general industrial cooling, while evaporative condensers are preferred for refrigeration, chemical, and energy systems where gas condensation is essential.
Fangnuo’s condensers are widely used in pharmaceuticals, food processing, steel, and electronics industries, and have been adopted by major enterprises such as Sinopec, Huawei, Geely, and Baosteel, reflecting their reliability and performance in demanding conditions.
Conclusion
Though similar in cooling principle, evaporative condensers deliver higher efficiency by combining heat condensation and cooling in a single system. With years of expertise and certified quality management, Fangnuo Heat Transfer System (Jiangsu) Co., Ltd. continues to advance evaporative condenser technology—offering energy-saving, space-efficient, and reliable cooling solutions across global industries.
