The Origin of Industrial Thermal Engineering
Fractional evaporative cooling technology was born in the late 19th century, right in the middle of the Industrial Revolution:
-
Pioneering (1898): American engineer Robinson de Paris patented the pioneer concept of an open-circuit cooling tower.
-
The Technological Challenge: Compressors and steam engines relied on municipal tap water to cool refrigerant gases. The water absorbed operational heat and was flushed directly into the drain—an unsustainable waste for urban and industrial growth.
-
The Scientific Solution: A thermal dissipation system was created where air blew in the opposite direction of a controlled internal shower. Fractional evaporation lowered the liquid temperature, allowing continuous recirculation through condensers.
From Wasted Water to Sustainability in Gelato & Ice Cream
With the expansion of continuous freezers and pasteurizers in the 20th century, uninterrupted cooling became crucial:
-
The Waste Era (1920–1950): Municipal water passed through the condenser and went straight down the drain.
-
Economic and Ecological Pressure: Post-war consumption growth, combined with high water costs and environmental restrictions, made water recycling mandatory.
-
Cooling Towers Enter Factories (1960–1980): Timber and galvanized steel towers were installed outdoors and on rooftops, evaporatively cooling hot condenser water and returning it to the production line.
The Evolution of Materials: From Heavy Steel to Closed Systems
Materials engineering transformed thermal tower efficiency over the decades:
-
Heavy Structures (1930–1960): Companies like Marley (now part of SPX) and BAC led the era of treated timber and heavy carbon steel structures.
-
The Era of Fiberglass and Polymers (1970–1980): The emergence of FRP (Fiberglass Reinforced Plastic) panels and PVC fills eliminated corrosion, reduced weight, and optimized heat exchange in humid environments.
-
The High-Efficiency Era (2000s+): Closed-circuit heat exchangers and EC/variable frequency drive fans emerged, protecting the system against external contamination and drastically cutting power consumption.
Finamac® Global Leadership: Science, Modularity, and Industrial Design
Since 1985, Finamac® has designed, manufactured, and delivered over 1,500 cooling towers worldwide. The precision level of our projects has made Finamac® equipment the subject of academic theses in mechanical engineering faculties.
The new generation of TR-7 Modular Towers introduces an unprecedented standard of flexibility and technology:
-
Smart Modular Systems: Available in Stainless Steel or High-Strength Fiberglass, the system allows side-by-side coupling without replacing equipment with giant single towers. Each module delivers 7 TR capacity—by joining 3 modules, your factory reaches 21 TR in a simple and scalable way.
-
Active Protection and Advanced Aerodynamics: The intelligent cabinet prevents leaf and debris entry (preserving thermal efficiency) and features an oversized aerodynamic channel designed to operate at maximum efficiency even in high relative humidity climates.
-
Flawless Performance and Industrial Aesthetics: While the market hides its towers in obsolete locations, Finamac® designs equipment with futuristic, clean, and elegant aesthetics. A structure built to remain visible in your factory, showing the market that your company uses world-leading technology!
