Cooling Towers Principles

Closed-Circuit Cooling Tower vs. Open-Circuit Cooling Tower Cooling towers are essential for rejecting heat in industrial and HVAC systems. The key difference between closed-circuit and open-circuit cooling towers lies in how they handle the process fluid (water or coolant). 1. Closed-Circuit Cooling Tower

Role of Fills in Closed Circuit Cooling Towers (CCCTs) Unlike open cooling towers, which rely heavily on fills for heat exchange, Closed Circuit Cooling Towers (CCCTs) primarily use heat exchanger coils to cool the process fluid in a closed loop. However, some advanced CCCT designs incorporate fills (also called adiabatic...

Closed Circuit Cooling Towers (CCCTs) are increasingly being used in data centres for efficient and reliable cooling. Here’s how they are applied and their key benefits: 1. How CCCTs Work in Data Centres Closed-Loop Design: CCCTs keep the cooling water isolated from the external environment, circulating it through a heat exchanger 2. Key Benefits...

The material of construction (MOC) for a closed-circuit cooling tower (CCT) depends on factors like durability, corrosion resistance, environmental conditions, and budget. Below is a detailed breakdown of materials used for key components: 1. Casing/Structure (Frame & Enclosure) a) Galvanized Steel (Most Common) Hot-dip...

The heat exchanger coil (primary cooling coil) in a closed-circuit cooling tower (CCT) is a critical component, and its material must balance thermal efficiency, corrosion resistance, durability, and cost. Below are the most common materials used, along with their pros, cons, and typical applications: 2. Stainless Steel (SS 304 / SS 316) –...

A Closed-Circuit Cooling Tower (CCT) consists of several key components that work together to provide efficient cooling while keeping the process fluid isolated from the external environment. Here’s a breakdown of the main parts: 1. Heat Exchanger Coil (Primary Cooling Coil) Function: Contains the process fluid (water/glycol) that needs...

Energy Saving Opportunities in Cooling Towers

Benefits of using Closed-Circuit cooling tower in area where what scarcity is available  Using a Closed-Circuit Cooling Tower (CCT)in areas with water scarcity offers significant advantages due to its water-saving design, reduced evaporation loss, and efficient operation. Here are the key benefits in such regions:  1. Minimal Water Loss...

Cooling towers help reduce the environmental impact of industrial cooling by efficiently managing heat dissipation and conserving water through the recirculation of cooled water. A closed loop system protects the quality of the process fluid, reduces system maintenance, and provides operational flexibility at a slightly higher initial cost. If an...

Benefits  • Contaminant-free cooling circuit • Dry operation in winter  • Reduced system maintenance  • Lower overall system costs thanks to year-round savings on maintenance, water, energy and water treatment

Principle of operation  Closed-Circuit cooling towers or fluid coolers operate just like the open type, but dissipate the process fluid heat load into the ambient air via a closed-circuit heat exchanger. This isolates the process fluid from the outside air, keeping it clean and free of contamination in a closed loop and creating 2 separate...

Hot process fluid enters the tube bundle from the inlet, and the spray system and fan system are started at the same time. Spray water is evenly sprayed on the surface of the tube bundle and a large amount of the air enters from the air inlet louver at the top of the tower and […]

Hot process fluid enters the tube bundle from the inlet, and the spray system and fan system are started at the same time. The spray water flows downward. The heat of process fluid is transferred to the circulating spray water running through the outer surface of the tube bundle in a way of tube wall […]

They have different air inlet directions. In the cross-flow cooler, the air inlet direction and spray water flow direction make a right angle. However, mixed flow Closed-Circuit cooler has two air inlet directions. In one direction, the air enters from the top of the cooling tower. In the other direction, the air enters from one […]

They have different air inlet directions. In the cross flow cooler, the air is introduced from the side of the tower and flows horizontally, making a right angle to the direction of spray water. However, in the counter flow cooler, the air is introduced at the bottom of the tower and flows from bottom to […]

Hot process fluid enters the coil (or tube bundle) from the water intake, and the spray system and fan system are started at the same time. The heat of process fluid undertakes heat transfer via tube walls and is transferred to the spray water running through the outer surface of the tube. The process water […]

Counter flow cooling tower is a cooling device that is designed to remove the heat of the process fluid, thereby cooling the process fluid. With coil exchangers placed in the tower, the whole cooling process is achieved through heat change among the air, spray water & circulating water via coil exchanger inside. In the counter […]
