Difference between a chiller and a cooling tower

difference between a chiller and a cooling tower

If you’re considering a local factory or warehouse owner, looking to upgrade your current cooling system, it’s essential to understand the differences between a cooling tower and an air-cooled chiller. Both can serve as efficient options. Though how effective, depends on the factory’s use.

Choosing a system without thoroughly evaluating your individual needs may result in suboptimal performance and elevated utility expenses. To ensure you make a well-informed choice, it’s crucial to explore the differences in cost and functionality between cooling towers and air-cooled chillers.

Differentiating Chillers and Cooling Towers

Chillers and cooling towers, though serve the main purpose of cooling, tend to operate differently. They essentially operate the removing heat.

Chillers extract heat from the coolants and release it into the air around it. In contrast, a cooling tower eliminates heat from water as it flows from the system’s condenser or heat exchanger.

Choosing the most suitable system for your production and operations needs depends on factors like:

  • The layout of your building,
  • The space available at your premises, and
  • The intensity of cooling you need.

We will delve into this further below.

Choosing the Right One

There is a strong chance that choosing the wrong type of cooling system won’t properly cool your factory premises, making the system less efficient.

You should consider the type of chiller or cooling tower before making the final purchase. The uses and applications vary depending on the type.

Types of Chiller Systems

Usually, you can meet your industrial cooling requirements by choosing between two types of chillers: water-cooled and air-cooled.

Air-Cooled Chillers

Industrial air-cooled chillers can be used in a variety of operations such as in air conditioning systems or the cooling process of industrial manufacturing plants. They can operate without a cooling tower.

These are frequently used in commercial establishments, like shopping complexes, medical centers, and corporate offices, where extra heat is needed.

Earnest is a manufacturer of choice for businesses that need industrial air-cooled chillers in Bangladesh. They have a good number of air-cooled chillers to boost your business’s cooling system.

Water-Cooled Chillers

Water-cooled chillers can be used in various operations including air conditioning systems and the heat removal process of industrial manufacturing. These chillers will require you to have a separate cooling tower, which makes them more efficient in the heat removal process than their cousin air-cooled chillers.

The combination of a water-cooled chiller with a cooling tower enables the highest level of efficiency achievable with these cooling systems.

Earnest is one of the largest manufacturers of industrial water chillers in Bangladesh, producing 16 to 5,500 Tons capacity and sustainable refrigerant options.

Different Uses of Chillers

Choosing the right chiller that aligns with your industry and company’s specific needs. This is crucial for boosting efficiency and minimizing expenses.

The top uses of chillers include:

  • In Refrigeration operations.
  • Plastic-industry applications.
  • Wineries and microbreweries.
  • Metal-finishing and waterjet cutting work.

Types of Cooling Towers

Purchasing cooling towers for industrial applications also has particular types and uses.

Crossflow Cooling Tower

A crossflow cooling tower represents a concurrent flow of gas and water. These types of cooling towers operate by dispersing hot water in a direction that crosses the path of the airflow. The process starts with water moving down from the cooling tower’s top, through the hot water gravity distribution basin, and into the fill. During this movement, the cooling tower fan pulls air through the fill in a horizontal direction.

Square cooling tower system

This type of cooling tower uses a directly driven fan, which is combined with a powerful motor. It also has spray nozzles for minimum drift losses. A hot-dipped galvanized hardware surrounds the tower.

It works via the induced draft counterflow system. Its fan system provides top-notch vertical air movement on the fills and opposite to the main water flow.

Local cooling tower producer Earnest employs an in-house engineering department to design and produce top-quality cooling towers using quality-assured materials that set quality standards high.

Different Uses of Cooling Towers

Cooling towers are commonly used for:

  • Thermal power stations
  • Oil and gas refining facilities
  • Power plants that are close to rivers and lakes
  • Large mechanical operations that generate lots of heat

Cooling towers have superior efficiency and better suit extensive applications. Industries like paper production facilities, chemical management locations, power plants, and other energy refinement processes usually opt for cooling towers over chillers due to their substantial cooling capacities. As for chillers they are preferred for smaller-scale processes like plastic or food production, where the release of too much heat does not pose many issues.

Where to purchase Chillers or Cooling Towers in Bangladesh

Heat removal is crucial, but it’s not easy either. You need powerful machinery to ensure the cooling system performs right.
For that reason, you need to carefully select an appropriate manufacturer or supplier of chillers or cooling towers. In a country like Bangladesh, where low-quality products creep in easily all over, you must reach out to a trusted, expert, and authentic supplier of industrial equipment.

You should look for suppliers who provide products that are

✔ Affordable
