Backed by experience of two decades, Shachi Engineering is a leading spray cooler manufacturer in India.
Our spray cooler specializes in handling materials with high heat sensitivity, and are designed with focus on achieving the right particle size. Installation and operating costs, and environmental impact are key factors are considered while designing our advanced spray cooler. Our specially designed spray cooler can achieve energy efficiency, cost-effectiveness, and lower carbon footprint during the entire operation. We can design both open and closed loop spray cooler.
Spray cooler are designed by using advanced Computational Fluid Dynamics ( CFD) technology for accurate results. Over the years, we have built the capacity to supply spray cooler of any desired specification and capacity, and we are committed to providing continuous service support to help you get the best performance.
Spray Cooler Working Principle
In spray cooling, the material to be cooled is passed from a chamber through which low-temperature air is also passing. The heat transfer between the hot particles and cool air results in the formation of fine powder. hen, the material passes through the conveying duct of the powder dryer machine. Here, the powdered particles are cooled and hardened. The air and powder is then separated in the cyclone separator, and powder is discharged through the rotary valve. Meanwhile, the air gets chilled in the heat exchanger and is again supplied into the cooling chamber. Not only does this help optimize the energy consumption, but also minimizes the load on dehumidification units when the spray cooler is operating in a humid atmosphere.
When melted material first comes into contact with cold air, it begins releasing heat. Then the material begins to congeal at constant temperature and then further cool into stable solid particles. However, not all materials go through the congealing phase. Some fluids go directly into hard solid state without releasing the solidification heat. Spray cooler manufacturer must consider the properties of the melted material to be cooled and the behaviour of its particles in the cooling chamber in determining the design of the cooler.

Factors Affecting Performance of Spray Cooler
- Flow rate and pressure of the cooling medium: The flow rate and pressure of the cooling medium can affect the size and velocity of the droplets that are sprayed onto the hot material, which can impact the cooling efficiency.
- Temperature difference between the cooling medium and the material being cooled: The greater the temperature difference between the cooling medium and the material being cooled, the more efficient the cooling process will be.
- Surface area of the material being cooled: The greater the surface area of the material being cooled, the more efficient the cooling process will be. This can be achieved by using a spray nozzle that produces a fine mist or by increasing the number of nozzles.
- Type and quality of the cooling medium: The type and quality of the cooling medium can affect the efficiency of the cooling process. For example, using pure water as the cooling medium is more efficient than using water with impurities.
- Distance between the nozzles and the material being cooled: The distance between the nozzles and the material being cooled can affect the size and velocity of the droplets that are sprayed onto the material, which can impact the cooling efficiency.
- Velocity and temperature of the material being cooled: The velocity and temperature of the material being cooled can affect the efficiency of the cooling process. Higher velocity and temperature can reduce the cooling efficiency, while lower velocity and temperature can increase it.
- Design and placement of the nozzles: The design and placement of the nozzles can affect the uniformity of the cooling process, as well as the overall efficiency of the spray cooler. For example, using multiple nozzles placed at different angles can improve the uniformity of the cooling process.
