Alfa Laval, Finland, reports that its next generation in efficient cooling, Abatigo, is optimized to deliver long-term savings in water, energy, chemicals, and maintenance time. With energy and water becoming very precious resources, applications in heat rejection are facing increasing challenges to achieve both economical and ecological sustainability. Customers in various industries are on the search for alternatives to open cooling towers due to the high water consumption and treatment required, as well as risks of Legionella contamination, Alfa Laval notes.

 

 

While dry coolers might seem like a perfect solution for most applications, certain limitations appear when it comes to some specific duties with a narrow temperature approach and challenging climates. This is why, Alfa Laval says, it is now introducing Abatigo.

Abatigo utilizes a unique method of cooling by spraying a fine mist of water to cool the air before it enters the heat exchanger coil. This significantly reduces energy and water consumption, and is highly adaptable to different applications and climates. The closed adiabatic chamber prevents any water drift to the heat exchangers, keeping them completely dry – preventing scaling, erosion, and dangerous waterborne diseases.

Benefits at a glance:

• Up to 95% reduction in water consumption versus. cooling tower
• No water treatment required for adiabatic system
• Perfect water temperature through precise controls that continuously adjust fans and adiabatic chamber activation as needed
• Maximized uptime thanks to scale-free operation, durable construction, and safer acrylic-coated heat exchanger
• Up to 95% lower energy consumption versus air-cooled central chiller
• Maximum capacity, low footprint compared to dry coolers.

The Alfa Laval Abatigo design is optimized using a modular concept, which means that 1–20 fans per unit can be arranged in single or double row configurations, depending on the capacity need and available space. EC fans ensure close temperature control and energy consumption based on actual load conditions. Fans come with exhaust diffusers for increased energy efficiency.

In addition, with every unit of Alfa Laval Abatigo, Alfa Laval offers a comprehensive portfolio of services including monitoring, smooth and safe startup, and maintenance services.
