Sostituzione delle torri di raffreddamento nello stabilimento farmaceutico di Grangecastle, Irlanda

Like most cooling tower projects, a thorough discussion of all the project details was key to determining the requirements for the facility and to meet the needs of the engineers. Local Marley representatives, Cooling Towers & Accessories (CT&A), and SPX Cooling EMEA met with the team and offered solutions that would satisfy the project scope, including:

• Flexibility to accommodate the operator’s N+1 phased production scale-up
• Designs capable of matching existing footprint and capacity
• Limit noise due to nearby business operations and existing sound concerns

The project team determined that Marley® NC Cooling Towers (Model 8411UCN) would be the right solution, with the following specifications:

• Material of Construction: Stainless Steel S304
• Fill Pack: 15 Mil PVC MX75
• Fan Type: Ultra Quiet Fan
• Mechanicals: Motor Inside Airstream with Marley Geareducer® gearbox
• Controls: Basin level and heater controls and vibration control panels

The cooling towers were delivered to the site and positioned near the existing platform until installation the following week. Within two weeks after install, the cooling towers were started up and effectively met the operator’s cooling load requirements, with additional benefits along the way, including:

• Energy Efficiency: The facility’s N+1 solution provides a lower-energy cooling option, which also minimizes noise impact, especially with the addition of the Marley Ultra Quiet Fan in the new towers.
• Operational Flexibility: The variable flow capability of the Marley NC supports a gradual increase in cooling demand while mitigating risks of icing and bacteria through continuous wetted surfaces and water circulation.
• Enhanced Monitoring & Maintenance: Basin level, heater and vibration monitoring provides advanced operational insights, limiting downtime and keeping the operators informed of potential concerns.

The collaboration of the operator, engineering house and CT&A was essential to this project. All parties understood the importance of finding the right solution designed for flexibility and long-term performance. The Marley NC Cooling Towers provided an energy-efficient, flexible and noise-reducing cooling solution for the growing facility, and the well-known durability and reliability of Marley products will help to ensure successful operation for years to come.
