Innovative Adiabatic Systems
Ecodry Adiabatic Coolers | Patented Free Cooling Technology
Ecodry adiabatic dry coolers use ambient air as the primary cooling source, adding a fine evaporative mist on the coil's air-inlet pads only when ambient temperature rises above a programmable threshold. The result is dry-cooler simplicity for most of the year, with adiabatic assist reserved for peak hours — a strategy Frigel calls 'Peak Looping'. In a typical European climate this delivers total free-cooling for roughly 71% of annual hours, partial free-cooling for another ~24%, and mechanical backup for only ~5%.

Free-Cooling as Standard, Water Only When It's Needed
Stop Wasting Water and Energy: Traditional evaporative cooling towers are high-maintenance cost centers that waste millions of gallons of water and carry severe operational risks. Frigel’s Ecodry Adiabatic Cooling System eliminates these inefficiencies through a closed-loop, intelligent process cooling technology that delivers maximum thermal performance with minimal environmental impact.
Core Performance & Sustainability Highlights
- From 60% to 95% Water Savings: Operates completely dry for most of the year, using water evaporation via thin-mist adiabatic chamber spraying only during peak ambient temperatures.
- PUE improvement: 2.00 (dry cooling) → 1.71 (Peak Looping + Adiabatic)
- Water use ratio (WUE): ~0.2–0.5 L/kWh vs. 1.5–3.0 L/kWh for a cooling-tower plant
- Up to 15% Energy Reduction & 30% COP Improvement: Advanced EC fan motor technology combined with smart demand-driven controls optimizes power consumption in real time.
- Patented CoolPad Chamber: Internationally patented adiabatic chamber with water-drift prevention, flame-retardant material, and GREENGUARD GOLD certification.
- 100% Anti-Legionella Safety: Certified to VDI 2047 Part 2 (Neridion, 2022): no aerosol generation, no bacterial proliferation, no water stagnation.
- Glycol-Free Operation Down to -40 °C: Self-draining gravity coil configurations ensure complete frost protection without costly or environmentally hazardous chemicals.
- Booster System for Extreme Heat: Direct spray cooling engineered for extreme ambient peaks, with no scaling on the coil surface and aerosol-free operation.
- Zero-Maintenance EC Fans: Advanced EC motor technology with integrated Modbus communication and 0–10V control signal on every fan.
- Modular, Wide & Deep: Staged deployment from pilot installations to hyperscale campuses without changing the base technology.
The Operational Advantage: By keeping process water continuously clean and scale-free, Ecodry guarantees constant heat transfer efficiency, zero internal pipe fouling, and minimal ongoing chemical treatments—slashing overall operational running costs, which account for 95% of a cooling system's TCO.

- Italy: Chemical / alcohol production plant: cooling-tower replacement for 2 MW, expanding to 6 MW during 2025.
Performance and sustainability without compromise
ASHRAE Standards
The ASHRAE standards with the new permitted operating parameters make it possible to work within the data center with higher temperatures, so the use of Free-Cooling and different cooling technologies compared with the traditional ones becomes even more advantageous.
Hybrid Dry Coolers
In Hybrid Dry Coolers, adiabatic cooling is made possible by special adiabatic chamber with special aluminum fins which, thanks to optimum water distribution, lower the air temperature due to water evaporation. This means additional operating hours in Free-Cooling mode.
Given the new ASHRAE ranges permitted, it will undoubtedly be even more advantageous in the future to use Hybrid Dry Coolers in Data Centers in applications at increasingly high temperatures as a back-up for cooling operations with chillers.
Total modularity
1. Easily expandable at any time
The Ecodry System allows the installation of the exact capacity required at each stage of plant development.
2. Gradual implementation
Even in existing plants, installing additional units is very simple thanks to the functional and effective modularity design.
3. Exact quantification of costs by line and product
Each unit can measure and record the specific energy consumption for each product.
4. Total reliability
The extreme simplicity, reliability and redundancy of the components of the adiabatic cooling unit minimizes the possibility of plant shutdown due to failures of the cooling system, ensuring the continuity of production 24 hours a day.
Free Cooling
Free-cooling is a concept whereby ambient air is used for cooling when the ambient temperature is lower than the data hall air (direct free-cooling) or the chilled water (indirect free-cooling).
In hydronic solutions free-cooling starts when external conditions ensure even a minimum coverage of the thermal load requirements. Thanks to the application of modulating free-cooling to maximize the free external source, the percentage of free-cooling increases proportionally in relation to the temperature difference between the internal and external environments, thus notably reducing the contribution of mechanical cooling and maximizing overall system efficiency.
Free-cooling is even more effective with high water temperatures, ensuring maximized energy savings.
Minimized water footprint
Unlike traditional systems, such as the evaporative tower, this new heat dissipation technology consumes water only during periods of extreme environmental temperatures, reducing water consumption to a minimum.
Reduced risks of emissions
1. Low GWP refrigerant
The system uses a refrigerant gas with the lowest GWP available to date.
2. Risk of losses and emissions reduced to a minimum
In each unit the refrigerant gas is divided into small separate circuits, minimizing the risk of emissions in the event of leaks.
3. Without disposal of chemical additives
It does not require the disposal of chemical additives used for water treatment.
