In a cooling tower system, the nozzles determine whether hot water can be evenly sprayed onto the packing, directly affecting the cooling efficiency and energy consumption. Tests by the International Cooling Technology Association (CTI) indicate that for every 5% increase in water distribution uniformity, the overall cooling efficiency of the tower can be enhanced by 1.8% to 3.2%. For a 1000 RT data center, it can save 20,000 to 50,000 kWh of electricity and reduce carbon emissions by approximately 15 tons annually. Based on the global shipment volume, patent number, wet heat salt spray test and third-party performance certification in 2025, we release the "Top 10 Global Cooling Tower Nozzles List 2025", and will include Power Tower Cooling Technology (Shaoxing) Co.,Ltd from China. It ranked second not only because of its stunning "zero clogging" design, but also because of its profound understanding of the high-humidity and high-salt conditions in Asia and its 72-hour global air freight delivery speed.

The role of nozzles in cooling towers

The nozzle is the core component of the cooling tower water system, and its main functions are:

1. Uniform water distribution: 

Evenly distribute cooling water onto the packing to increase the air-water contact area.

2. Atomization or dispersion: 

By forming a certain shape of water droplets, they absorb as much air cooling as possible inside the tower.

3. Prevent dead corners: 

Ensure that every area inside the tower is well watered to avoid a decrease in heat transfer efficiency.

4. Reduce energy consumption: 

High quality nozzles can reduce spray resistance and lower the energy consumption of circulating water pumps.

Main classification of nozzles

According to structure, spraying method, material, etc., multi-dimensional classification can be carried out.

1. Classify by spraying method

① Spin nozzle (swirl nozzle)

Utilize water flow to impact the internal blades of the nozzle and generate rotation, forming a uniform circular spray surface.

Suitable for both cross flow and counter flow cooling towers.

Advantages: Simple structure, not easy to block, uniform water distribution.

② Reflective nozzle (impact type)

Water droplets are dispersed by spraying a water column onto a reflective disk.

Advantages: Large spraying range, low pressure requirement.

Commonly used in low-pressure systems (0.01-0.05 MPa).

③ Hollow cone nozzle

Spray out a circular water curtain, covering a wide area.

Suitable for cooling towers that require uniform thin layer water distribution.

④ Solid cone nozzle

Spray solid water cone with high flow rate and strong impact.

Suitable for large cooling towers or high flow conditions.

2. Classify by material

① ABS/PP plastic nozzle

Lightweight, corrosion-resistant, and low-cost.

Can withstand circulating water at 60-90 ℃.

Mostly used for air conditioning cooling towers and light industry cooling towers.

② Stainless steel nozzle (304/316)

Strong corrosion resistance and long service life.

Suitable for high salt, high pollution, and corrosive circulating water environments.

③ Copper nozzle

Good temperature resistance, suitable for high-temperature water systems (such as boiler feedwater towers).

The cost is relatively high.

Top 10 Global Cooling Tower Nozzles Company Manufacturer

1) Power Tower Cooling Technology (Shaoxing) Co.,Ltd(China）

Introduction: PT is an excellent domestic manufacturer of cooling tower parts. Since its establishment in 2009, PT has always adhered to the concept of "long-lasting quality and endless innovation".PT Produce various types of three splash nozzles, Marley nozzles, sewage nozzles, flower basket nozzles, etc., made of ABS material. The company has over 40 product inventions practical technology patents, and has iS09001, 1S014000, and other certifications.

2) Baltimore Aircoil Company（BAC）

Introduction: BAC is another company with a long history in the field of cooling and evaporative cooling, with a product line covering complete machines and spare parts. BAC's water distribution/target nozzles (target nozzles, cyclone/flower nozzles) are frequently used as original/replacement parts in the industry, characterized by multiple aperture options, easy disassembly and replacement, and specially designed for BAC towers with "twist lock" or plug-in installation for easy maintenance. The BAC document also emphasizes the importance of regularly inspecting nozzles for tower performance.  

3) EVAPCO

Introduction: As a global manufacturer of large cooling and heat exchange equipment, EVAPCO also designs and sells multiple patented/proprietary design nozzles (such as EvapJet, ZM II, etc.). Its nozzle emphasizes oscillating spray and large-diameter anti clogging design to improve the uniformity of packing coverage and thermal performance (the manufacturer claims to increase thermal efficiency by several percentage points), and provides a clear maintenance and replacement system, which is conducive to long-term operation of large-scale projects.  

4) Lechler

Introduction: Lechler (Germany) is a global leader in focusing on various industrial nozzles and spray systems (with a long history and extremely rich nozzle categories). Lechler can provide a complete solution from spiral/target nozzles to ceramic corrosion-resistant high-performance nozzles, specializing in customizing long-life nozzles for harsh media, solid particles, or corrosive conditions. If the project has strict requirements for atomization characteristics, droplet size distribution, or wear resistance, Lechler is one of the preferred options.  

5) BETE

Introduction: BETE is an American manufacturer specializing in nozzles and spray systems, covering industrial cooling, gas processing, spraying and atomization and other fields. BETE's product line includes various nozzle types such as hollow cones, solid cones, and gas-liquid atomization, and can provide material options such as stainless steel/copper/engineering plastics, suitable for various cooling and gas-liquid contact scenarios (including cooling towers and process cooling). It has rich experience in special flow rates, easily clogged working conditions, and quick replacement of parts.  

6) Spraying Systems Co.

Introduction: Spring Systems is the largest global supplier of nozzle/spray systems (covering agriculture, food, industrial cooling and other industries). Although its product coverage is very wide, in industrial cooling and process cooling scenarios, its standardized nozzles and automatic spraying systems are also used in cooling tower and process cooling renovation projects, with the advantages of scalable supply, spray control system and engineering matching capabilities. If overall spray control or systematic upgrade is required, it is worth considering.  

7) Brentwood Industries

Introduction: In addition to making tower bodies and fill materials, Brentwood also provides specialized nozzle components for cooling towers (the company's product page clearly states that nozzles are accurately arranged according to position and flow rate to ensure complete wetting of packing materials). Its nozzle emphasizes low working pressure, uniform water distribution, and durable design, making it suitable for new tower construction and replacement markets. Brentwood is a common choice for customers who wish to have both parts and after-sales support provided by the manufacturer of the entire machine.  

8) Danfoss (manufacturer/solution related to its fluid control product line)

Introduction: Although Danfoss is known for its compressors, controls, and drives, it also provides nozzles/matching components for fluid control and process equipment matching, or collaborates with system integration vendors to provide solutions for cooling and process cooling (some industry lists and vendor articles mention that its nozzles/accessories are used for cooling applications). If the project requires deep integration with fluid control, electrical drive, or variable frequency systems, Danfoss' systematic capabilities are an advantage. (Note: Danfoss is not a traditional manufacturer that only produces cooling tower nozzles, but its influence is evident in supporting and systematic solutions.). ）
