A Dry Cooling Tower is a type of cooling system that operates without water evaporation, making it ideal for regions with water scarcity. It functions by transferring excess heat from industrial processes through a closed-loop system, where heat is dissipated via air-cooled heat exchangers with extended fins.

Key Features:

• Closed-Circuit Operation: Heat is transferred through a surface separating ambient air from the working fluid (typically water or a water-glycol mixture).
• Air Cooling Technology: Uses natural or mechanical draft to move air over heat exchangers, eliminating the need for water evaporation.
• Minimal Water Consumption: Unlike wet cooling towers, dry cooling towers do not require makeup water, reducing operational costs.
• Applications: Commonly used in power plants, industrial cooling, solar energy systems, and HVAC applications.

Technical features

Our air-cooled scroll chillers can reduce your total cost of ownership because they are engineering for lower life cycle costs and reliability through design simplicity. Our compressor technology is direct drive, low speed (3600 rpm) with only two rotating parts for high reliability and efficiency. Optimized compressor parts profiles are designed specifically for chilled water applications to optimize full and part-load efficiency. Our 'Smart H' Microprocessor provides greater reliability through a proactive control strategy, safety functions with simple diagnostics and easy interface with any building automation / energy management using a single twisted pair of wires. Hiver air-cooled scroll chillers are the right choice for tight temperature control in virtually any application.

Our compact chillers install easily and quickly into most building / factory layouts, making them ideal choices for retrofit or new building designs.

An evaporative condenser is a condenser integrated into a cooling tower which rejects the latent heat of condensation of refrigerant (Ammonia/Freon) through a coil to the surroundings by means of evaporation.
Water sprayed onto the coil exchanges heat with the refrigerant. A small quantity of water is evaporated into the air thereby cooling the remaining water cascading to the basin at the bottom. Post evaporation the saturated air passes through the drift eliminators and then forced out using a fan.

Construction And Working Of Evaporative Condenser :

In evaporative condensers, both air and water are used to extract heat from the condensing refrigerant. Figure shows the schematic of an evaporative condenser. Evaporative condensers combine the features of a cooling tower and water-cooled condenser in a single unit. In these condensers, the water is sprayed from top part on a bank of tubes carrying the refrigerant and air is induced upwards. There is a thin water film around the condenser tubes from which evaporative cooling takes place. The heat transfer coefficient for evaporative cooling is very large. Hence, the refrigeration system can be operated at low condensing temperatures (about 11 to 13 K above the wet bulb temperature of air). The water spray counter current to the airflow acts as cooling tower. The role of air is primarily to increase the rate of evaporation of water. The required air flow rates are in the range of 350 to 500 m3/h per TR of refrigeration capacity.

e manufactures two types of closed circuit cooling tower and combined flow and counterflow coolingtower. Closed Circuit Cooling Tower are suitable for Thermal Power Plants. Closed Circuit cooling tower certain processes needs a closed loop, that's why the process water for cooling does not come in make contact with the full of atmosphere air. Closed loop type cooling is minimizes process fouling.

Types of Closed Circuit Cooling Tower

• Combined Flow
• Counter Flow

We may well include various percent of the cooling water from the available water resources to the closed circuit cooling system and we be able to decrease the cooling tower size.

Mixing ration means the percentage of the added water. If our mixing ratio is zero, it is called absolutely closed system. When the mixing ratio is 100%, it is called an open system.

Closed Circuit Cooling Tower Water Temperature

Closed Circuit Cooling Towers are accomplished of incoming fluid temperatures as high as 180ºF (82.2ºC),.

Closed Circuit Cooling Tower Design

Our Closed Circuit Cooling System gives completely rated thermal presentation, which also by yourself verified over special types of flow and high temperature requirements. Closed Circuit Cooling Towers are high effciency and water saving.
