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

Advantages

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

Features

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)

Filtri modal

Internationally Patented Adiabatic Chamber.

  • High-temperature ambient air passes through the lower adiabatic chamber.
  • In the chamber, nozzles create a fine mist of water from a separate source.
  • Humidification of the air reduces the temperature prior to contact with the heat exchangers.
  • Patented design prevents water drift outside the chamber, eliminating heat exchanger scaling and avoiding the risk of proliferation of bacteria, such as Legionella. In addition, the absence of stagnant water helps to prevent bacterial development.
  • To ensure consistent cooling, the control system continuously adjusts the amount of water sprayed. The heat exchangers, meanwhile, remain completely dry.
