Case Story: Atlantic Grupa

Saving 89% of Water & 58% of Energy? This is how Atlantic Grupa Revolutionized its Cooling system with Frigel Ecodry Adiabatic System.

Client: Atlantic Grupa at its Argeta pâté factory in Izola, Slovenia.

Problem: The existing three closed-loop evaporative cooling towers were highly inefficient, leading to unsustainable water use (8,500 m³ annually), high energy costs (due to over-cooling and high pumping power), and operational instability (limescale buildup/fouling effect).

Solution: Implementation of Frigel Ecodry 4DK Adiabatic Coolers system.

Key Results: After one year of utilization the customer measured 89% reduction in annual water consumption and 58% reduction in energy usage.

Conclusion: The switch proved the overwhelming superiority of advanced adiabatic technology over traditional evaporative cooling towers, delivering a significant improvement in terms of environmental impact and economic return, setting a new ESG benchmark for the industry.

The Challenge: Limits of Evaporative Cooling

Atlantic Grupa's pâté sterilization process required a constant, critical supply of cooling water. The existing cooling towers had become a major liability due to three core issues:

1. Massive Water Consumption: The evaporative nature of the towers resulted in 8,500 cubic meters of water consumed per year, creating a significant strain on costs and the environment.
2. High Energy Costs: The system suffered from high pumping power and "over cooling," providing water at unnecessarily low temperatures, driving up the plant's overall energy use.
3. Operational Issues ("Fouling Effect"): Constant evaporation caused limescale buildup on heat exchangers, progressively reducing efficiency, reliability, and requiring high maintenance.

The Solution: Frigel Ecodry Adiabatic System

The obsolete cooling towers were replaced with the Frigel Ecodry System, which offers intrinsic advantages over traditional technology:

• Adiabatic Technology at its core: The system operates in a closed, sealed loop, protecting the coolant from contamination. For most of the year, it functions as a dry cooler, using only ambient air and low-energy fans. Water is only used as a fine mist to pre-cool incoming air during peak ambient temperatures, dramatically cutting consumption.
• Maintenance & Efficiency: The humidification process occurs in a closed, patented adiabatic chamber with no contact between the spray water and the coils, which cuts maintenance costs by 95% and prevents the fouling effect.
• Intelligent Control: A GPR pump group with Variable Frequency Drives (VFDs) and an IPC controller ensures precise water flow and temperature management, preventing wasteful over-cooling and delivering exactly the cooling needed.
• Expert Partnership: Frigel's analysis of climate and process needs ensured that an optimal configuration was engineered, maximizing the Ecodry system performance extracted both during design and off-design operations.

The Results

The implemented solution set a new benchmark for efficiency, delivering these measured, quantifiable savings:

• Water Consumption: 89%
• Energy Usage: 58%

These substantial figures demonstrate that the Frigel Ecodry System is an overwhelmingly superior technology that provides enormous environmental and economic returns compared to outdated, water-intensive cooling towers, reinforcing the commitment to companies’ corporate sustainability.
