Cross Flow Cubic Cooling Towers by DamaTajhiz

In the new generation of DamaTajhiz CROSS FLOW cubic cooling towers, air suction is only possible from two side panels of the unit. Thanks to the modern design and advanced technology used in manufacturing these cubic (cross flow) cooling towers, all the limitations and drawbacks of the older models (circular) have been fully resolved.
This blog post explains the advantages of DamaTajhiz cross-flow cubic cooling towers compared to traditional (circular) towers. For more information, please stay with us until the end.

Cross-Flow Cubic Cooling Towers Advantages

The benefits and advantages of this new generation of DamaTajhiz cooling tower, cross-flow cubic type, are as follows:

High Durability and Low Weight

The use of special alloy (hot-dip galvanized steel - HDG) in designing and building DamaTajhiz’s new generation cooling towers has significantly increased their durability while reducing their weight.

The Cross-Flow Cubic Cooling Towers' very Low Noise

To reduce noise in the new generation of DamaTajhiz cooling towers, the fan is designed with special angles and made of aluminum alloy. As a result, the sound level is significantly minimized, reaching a maximum of 51 dB at a 10-meter distance. This makes them one of the quietest units in their category.

No Vibration or Shaking in Cubic Cooling Towers

The special design and precise construction of the cooling tower's frame and other vibrational parts ensure that the unit operates smoothly, with zero vibration or shaking.

High-Efficiency Motor of Cross-Flow Cooling Towers

The fan drive motor is a three-phase model (IP=54 class) from top-tier brands, featuring long life, high efficiency, and compatibility with variable frequency drives (inverters). When used with an inverter, the unit's power consumption is smartly regulated, resulting in significant energy savings.
Using an inverter is especially recommended for large-capacity cooling towers and industries requiring precise temperature control, such as pharmaceuticals, plastic injection, steel, food processing, and more.

Minimum Energy Consumption under Partial Loads

The new generation of cubic cooling towers by DamaTajhiz is manufactured in various capacities ranging from 85 to 250 refrigeration tons. For large-scale projects, multiple units can be assembled and installed in modular (multi-cell) configurations based on the system’s needs. This setup allows for significant energy savings—when the chiller is operating at partial load, the motor of one or more cells can be turned off, reducing electricity consumption by up to 50%.

Compact Installation Footprint

The smart design of DamaTajhiz’s new generation cubic cooling towers allows the required airflow to enter only from two sides. Therefore, in projects where multiple units are needed, the towers can be installed side by side without any lateral spacing. This feature is particularly beneficial for rooftop installations in residential complexes where space is limited.

The Main Frame of Cubic Cooling Tower

As you know, the main frame of the cooling tower, which ensures structural stability, is crucial. In DamaTajhiz’s new generation cross-flow cubic cooling towers, the main frame is made of hot-dip galvanized steel (HDG), offering high durability, low weight, and strong resistance to humidity and harsh weather conditions.

Cross Flow Cooling Tower Air Intake Roller Shutter

The air intake roller shutter, installed on both sides of the unit, ensures even air distribution into the cooling tower. These roller shutters are made of high-quality fiberglass, specially treated for resistance against UV rays and extreme environmental conditions.

Peculiarly Designed Internal Packing

The internal fill media (packing) is available in two types: splash (honeycomb) and sheet type, depending on the application. For HVAC systems and processes where the incoming hot water temperature is not excessively high, sheet-type fill (with heat resistance up to 55 °C) is recommended. These PVC packs are flexible (anti-brittle) and UV-resistant.
The fill media used in DamaTajhiz’s cross-flow cubic cooling towers have a smooth surface, preventing scaling and mineral buildup due to evaporation. Other benefits of these sheet packs include easy replacement, flexible installation in required quantities, and effortless cleaning or descaling, without the need for acid washing or incurring additional maintenance costs.

Principal Chassis of Cooling Tower

Since the total weight of the cooling tower is supported by its chassis, the quality of the frame and base is critical. The main chassis of DamaTajhiz’s new generation cooling towers is specially designed and built with hot-dip galvanized steel (HDG). This material offers excellent corrosion and rust resistance, ensuring long-lasting structural stability without any vibration or shaking, even after years of operation.

Maximum Air Circulation with Less Energy Consumption

In the new generation of DamaTajhiz cross-flow cubic cooling towers, the fan blades are made from super blade aluminum alloy, which is very lightweight and highly durable. The precise design and shaping of the aluminum blades at specific angles, combined with their manufacturing quality, not only significantly reduce the device’s noise but also achieve the highest air circulation with the lowest electrical energy consumption in the motor.

Cross-Flow Cubic Cooling Towers Fan Guard

In the new generation of cooling towers, to prevent objects or foreign bodies from entering the fan compartment, the upper surface of this compartment is fully protected and covered with a rustproof galvanized steel mesh.

Ladder of Cross Flow Cubic Cooling Towers by DamaTajhiz 

To provide easy access to the top of the cooling tower during inspections, periodic maintenance, and possible repairs, a ladder made of hot-dip galvanized steel is installed on one corner. Additionally, installation of railings, protective guards around the tower, and an entrance step (for easier access inside the cooling tower) is available upon customer request.

Side Walls of DamaTajhiz Cubic Cooling Tower

The side walls of the DamaTajhiz cross-flow cubic cooling towers are made from fiberglass, which is very resistant to sunlight radiation. These walls are designed not only to have a beautiful appearance but also to completely enclose the inside air, directing airflow only over the packing surfaces to maximize cooling efficiency.

Handy Filter Installation

Considering the possibility of suspended particles and deposits from evaporated water damaging the pump fan, chiller condenser, or other related industrial equipment, the new generation of DamaTajhiz cross-flow cubic cooling towers uses stainless steel mesh filters in the water outlet path from the basin.

Easy Access Door for Maintenance and Repairs

One side wall of the cooling tower includes an access door for technicians. This inspection door provides easy access to the tower’s interior for periodic inspections, descaling, easy washing of the packing, and possible replacement.
Previously, descaling in older generations of cooling towers used to be done by acid washing, which was costly and problematic.

Anti-Freeze Heater of New Generation Cooling Towers

In industrial projects where the cooling tower is part of the process and production line, the device operates all year round, including winter. To prevent freezing of the tower water during cold hours (fall and winter), a heating system is designed for these towers. This heater can be installed on the device upon customer request.

Disadvantages of Round Cooling Towers (Old Generation) 

The main problems and disadvantages of old generation, round cooling towers include:

• Excessive water spray outside (high water waste)

• Higher energy consumption (higher electricity cost)

• Larger footprint due to greater air suction and larger device size

• High noise and vibration due to a single motor in large capacities

• Short device lifespan

• Very costly repairs, including mandatory replacement of all packing

• Early damages caused by motor shaft breakage in the water distribution system

• Rapid clogging of water nozzles in short intervals
