Ecodry 4DK

Innovative adiabatic cooler: the replacement for evaporative cooling tower

Pioneering the adiabatic cooling technology, 4DK is the latest evolution of our Ecodry 3DK. A centralized closed-circuit adiabatic cooling system designed to replace the old cooling tower technology. It removes the heat extracted from the process, achieving:

  • New level of efficiency with higher performance and better carbon footprint
  • Optimized to deliver long-term savings in water, energy, chemicals and reduced maintenance time
  • Robust construction and functional, unique design for tight spaces
  • Unique design for tight spaces
  • Design for health and safety that gives 4DK an anti-legionella certification

A fluid cooler with better performance

  • Compact design: Improved capacity/footprint ratio with 40% lower footprint required between the units

  • Total modularity, high reliability: Easy to expand at anytime to meet growing needs

  • Glycol-Free operation: 100% reliability in sever weather conditions down to -30°C (-22 ˚F)

  • Self-draining configuration optimizes performance with glycol-free applications in freezing climates

  • Minimal ongoing chemical treatment required


Total control

  • Low pressure loss heat exchangers with high performance copper/aluminum finned coils

  • Self-draining by gravity coil configuration for glycolfree operation

  • Unique Adiabatic Chamber (internationally patented) enclosed with fiberglass CoolPad and equipped with high efficiency air humidification spray nozzles

  • Energy or water saving mode: minimizing the fan energy consumption and water consumption

  • Dry – Adiabatic – Hybrid (Adiabatic + Booster) switch: automatic commutation from one mode to the other according to real load demand and actual ambient temperature

  • Water consumption management in Adiabatic mode: control of evaporation according to real-time cooling demand

  • Process pump management: automatic control of the pumping unit

  • Control of self-draining configurations without antifreeze

  • The metal structure is in SS304L stainless steel. For high corrosive atmosphere areas, it is recommended to select specific surface structures and/or treatment

  • Digital control and on-demand managing logics of the system (Netgel 3PR 4.0)

Power Grid


Effective cooling is an important task to make full use of the converter station and to improve the reliability of the system.

Data Centers

The most evolved free-cooling technology: customized solutions for data center

Data centre temperatures vary depending on the servers and type of cooling system, but temperature swings outside ASHRAE or design standards could have serious performance implications. Downtime at data centers is potentially catastrophic and every precaution should be taken to eliminate, or at least minimize, this threat.

Organic Rankine Cycle (ORC)

Optimized cooling solution and energy saving for a faster payback time. ORC is one of the most used solution to generate electricity from low temperature heat sources.
