Frigel Introduces Ecodry 3DK Closed Loop Adiabatic Liquid Cooler
Cooler can be precisely configured to manufacturers’ needs to maximize the benefits of closed-loop process
cooling, whether it’s higher energy savings or improved sustainability
Scandicci, FI, Italy – (15 May, 2014) – Introduced today by Frigel, the new Ecodry 3DK Closed Loop Adiabatic
Liquid Cooler can be configured to match manufacturers’ specific requirements, delivering higher energy and
water savings, environmental benefits and other advantages. Ecodry 3DK can also be configured to occupy a
30 percent smaller footprint than the Ecodry model it replaces.
As an alternative to conventional process cooling, Ecodry 3DK is the primary component of an integrated,
closed-loop intelligent cooling system that provides clean water at the right temperature to industrial
processes year round. The closed-loop approach can reduce water consumption by as much as 95 percent
when used instead of a cooling tower. Compared to an air-cooled central chiller, it can reduce energy
consumption by as much as 95 percent. Ecodry also eliminates chemical discharges and dangerous water
borne diseases, such as Legionella.
The modular Ecodry 3DK, which is housed outside a customer’s facility, is the closed-loop system’s central
cooler. It uses heat exchangers and an internationally patented adiabatic chamber to cool water circulated to it
from process machines. The adiabatic chamber pre-cools ambient air on hotter days before it enters the unit’s
heat exchanger compartment. Cooled water is then re-circulated to a facility’s process machines. The
microprocessor-based controller automatically maintains precise cooling temperatures.
As the next-generation Frigel Ecodry System, Ecodry 3DK incorporates a number of enhancements and options
so it can be readily tailored to each manufacturer’s business goals and plant requirements. This adaptability
gives companies the ability to:


Increase energy savings: Available fan exhaust diffusers located on top of Ecodry 3DK keep exhaust air
from being drawn into the adiabatic chamber at the bottom of the unit – while also allowing it to
consume as much as 28 percent less energy compared to the standard axial fan model.
Improve cooling precision: New options enable Ecodry 3DK to maintain precise cooling temperatures,
regardless of local climate. Options include a patent-pending adiabatic booster for water temperatures
equal to cooling towers and/or in hotter climates; varied heat exchanger configurations for milder
climates; and self-draining coils with recirculation pump stations for non-glycol applications in freezing
climates.



Reduce maintenance: A new acrylic coating is applied to the heat exchangers for added protection
against harsh environments, and to further reduce the need to maintain the already low-maintenance
system. An optional polyurethane coating provides an even higher level of protection.
Save space: With exhaust air diffusers, multiple Ecodry 3DK units can be positioned more closely
together. When air diffusers are not used, roof panels are another space-saving option. The panels
allow the multiple Ecodry 3DK units to be positioned closely together because they keep exhaust air
from flowing down and into the adiabatic chamber. Optional extended legs can also facilitate airflow in
tight spaces. The result is a footprint as much as 30 percent smaller than the previous Ecodry model,
depending on the configuration.
Frigel’s worldwide network of sales, service and engineering teams work closely with customers to configure
each Ecodry 3DK based on their application and location – and to ensure the closed-loop system delivers
optimum performance and efficiency beyond conventional cooling tower and central chiller systems.
