When a global metal casting company located in Iceland needed to install a new casting line to enhance its aluminium ingot production, three Eurovent certified Marley CP Cooling Towers from SPX Cooling EMEA, offered a reliable solution.

The project’s location presented several unique challenges, including a remote site with harsh operational conditions.

Working with SPX Cooling EMEA, the project team determined the right cooling towers for their needs, helping ensure that the casthouse remained online and any downtime related to the heat rejection system was minimised.

The project

The project offered a number of challenges. Firstly, the cooling towers required assembly in a laydown area several kilometres from the main plant due to space constraints, and then transportation to their final location. Secondly, the installation took place in sub-zero temperatures, requiring durable and corrosion-resistant materials. Thirdly, the cooling system needed to handle a heat load of 35,567 kW, with a flow rate of 1,245 m³/h and operate efficiently at temperatures as low as -25°C.

The project requirements included:

• Duty Parameters (Total across 3 x Cells)
• Flowrate (m3/h): 1,245 m3/h
• Hot Water Inlet Temperature (°C): 50
• Range (°C): 25
• Cold Water Outlet Temperature (°C): 25
• Approach (°C): 5.2
• Wet Bulb Temperature (°C): 19.8
• Heat load (kw/h): 35,567 kW

The product

To meet the client’s demanding requirements, SPX Cooling EMEA provided three Eurovent certified Marley CP Cooling Towers. The solution included:

Pre-engineered design: The cooling towers were shipped in small, manageable pieces (knocked down), allowing for easy onsite assembly.

Durable construction: The towers featured S304 stainless steel and fibre-reinforced plastic (FRP) construction, offering excellent corrosion resistance.

Integrated control system: A full control system was installed to monitor and regulate the towers and pumps, ensuring consistent cold-water temperatures for the quenching process.

The project was successfully completed in March 2024. Key outcomes included:

Efficient cooling performance: The system achieved the desired cooling parameters with a cold-water outlet temperature of 25°C, even in sub-zero conditions.

Reliable operation: The plant has been running commercially for nearly a year with no reported issues.

Flexibility and scalability: The modular design allowed for adaptable assembly and easy transportation, making the installation efficient and cost-effective.

Corrosion resistance and longevity: The use of stainless steel and FRP materials provided long-term protection against the harsh Icelandic environment.

With the help of the SPX Cooling EMEA team and Marley-engineered cooling towers, the casthouse can reliably control the heat rejection necessary in their quenching process, even in the Icelandic winter weather.

Proven performance

Being able to trust product performance, reliability and energy efficiency is vital in HVAC and Refrigeration (HVACR) projects such as this casthouse project. For the HVACR professional the added value of choosing a Eurovent certified product includes:

• Assurance that HVAC and Refrigeration systems will perform as expected.
• Free access to transparent, reliable and universally understood performance data, to search and compare products.
• The assurance that product data is accurate and has been independently tested by an expert, third-party.
