Cooling Tower Upgrade for Hungary Grain Facility

Project Challenges

The project involved the partial replacement of an existing four-cell HAMON wooden cooling tower while maintaining close coordination with ongoing facility operations. Because the new cooling towers needed to be installed directly next to the existing structure, careful planning and site execution were required throughout the installation process.

Additional project considerations included:
• Limited installation space adjacent to the operating tower
• Maintaining project timelines during on-site assembly activities
• Coordinating site-built installation within a strict 10-week project schedule
• Ensuring the upgraded system would achieve the required thermal performance targets

To meet the facility’s operational and performance requirements, the project team selected two Marley® NC Cooling Towers (Model NC8413WAS1GQK). The towers were supplied in knock-down kit format and assembled on-site prior to commissioning.

The supplied cooling towers included the following specifications:

• Material of Construction: Z725 Galvanised Steel
• Fill Pack: 20 Mil PVC MX75
• Fan Type: Low Sound Fan
• Mechanical Configuration: Motor Inside Airstream (MIA) with Marley Geardrive®

The cooling towers were assembled on-site and fully installed, commissioned and operational within the client’s planned 10-week schedule. The towers entered operation in August 2020.

The Marley NC Cooling Towers successfully met the facility’s required thermal performance and cooling capacity objectives while also delivering improved operating efficiency compared to the previous cooling tower system. Additional project benefits included:

• Improved Cooling Performance: The new Marley cooling towers achieved the required outlet water temperatures and cooling capacity targets necessary to support plant operations.

• Increased Efficiency: Compared to the older wooden tower design, the upgraded Marley solution provided a more energy-efficient and environmentally friendly cooling approach with reduced electricity and water consumption.

• Reliable Installation Execution: The on-site assembly and installation process was completed successfully within the customer’s scheduled timeline, minimising operational disruption.

• Long-Term Customer Confidence: Following the successful installation and operation of the towers, the client continued to purchase additional cooling tower units, reflecting the customer’s confidence in the Marley solution and support provided by Szanyo Refrigeration & Air Conditioning.

The collaboration between the client and Szanyo Refrigeration & Air Conditioning helped ensure the successful replacement of ageing cooling infrastructure while improving operational reliability and cooling performance for the facility’s long-term production requirements.
