Water saving
Evaporative cooling towers are used in a wide range of industries and result in the greatest use of water in industrial and commercial applications. While all cooling towers continuously recirculate water, a substantial portion is constantly evaporated and otherwise dispersed into the environment.
However, alternative technologies, such as the latest generation adiabatic coolers, can drastically reduce water consumption by up to 90-95% and even more, depending on the application and local climate conditions.
Carbon footprint
The carbon footprint is an environmental indicator that measures the impact of human activities on the global climate and expresses quantitatively the effects produced by so-called greenhouse gases (GHGs) in terms of carbon dioxide equivalent (CO 2 -eq). This is calculated by multiplying the emissions of each of the greenhouse gases by its warming potential (GWP).
The standard is based on the Life Cycle Assessment (LCA) methodology, a standardized methodology (ISO 14040 and ISO 14044) by which all analyzed all processes related to the product/service, from the extraction of the raw materials, through to end-of-life management.

FAQ
What are the main benefits of 4DK?
Just to highlight 3 out of severals:
- High level of modularity with compact design
- Self draining function for Glycol-free systems
- High peak load offset safety
Why is 4DK so efficient?
The dry-adiabatic hybrid concept of 4DK is totally managed by intelligent system control, the control logic optimizes the liquid coolers for each individual application, taking into account the annual variation of the temperature at the site and the expected load profile, giving priority to energy saving or water consumption. Due to the lower operating costs, the payback period is quite short.
How long (in general) do Adiabatic pads last?
Typically the longevity of the equipment is predominantly a function of water and air quality, as well as proper operation. With 4DK we focused on high quality material such as SS304L for casing, high premium Pads for long lasting performances with minimized maintenance. All in all the design is made for high reliability, if you think you need a replacement.
Why are traditional cooling towers an unsustainable cost and a health risk for the injection molding industry?
Traditional open-circuit evaporative cooling towers consume extremely large amounts of fresh water every day for evaporative heat rejection. Furthermore, they permanently expose the process water to environmental pollution, creating an ideal breeding ground for bacterial diseases, including the deadly Legionella bacteria.
The Frigel Ecodry 4DK is an advanced adiabatic cooler that operates as a closed-loop system, guaranteeing zero risk of Legionella, completely eliminating the need for expensive and ongoing chemical water treatments, and ensuring maximum health and safety for the plant operators.
How does the Ecodry 4DK adiabatic cooler compare to a cooling tower in terms of water conservation?
While a standard cooling tower constantly evaporates massive volumes of water, the 4DK series represents a paradigm shift in water conservation. It operates purely as a dry cooler for the majority of the year. Only during extreme ambient temperature peaks does it activate the internationally patented CoolPad™ adiabatic chamber, which pre-cools the incoming air using a highly efficient, aerosol-free mist of water.
This intelligent hybrid technology allows plastic manufacturers to reduce their water footprint by up to 95% compared to traditional cooling towers.
How does the 4DK's closed-loop system improve the efficiency of injection molding cooling?
In injection molding cooling, maintaining clean mold channels is critical for stable cycle times. Open cooling towers introduce dirt and cause permanent fouling and scaling inside the heat exchangers and mold channels, which dramatically decreases cooling efficiency and causes machine overheating.
The Ecodry 4DK utilizes a closed-circuit configuration with robust copper or 304L stainless steel tubes, ensuring that the process fluid remains perfectly clean and uncontaminated. This guarantees constant heat transfer efficiency, prevents scaling on coil surfaces, and eliminates the need to halt production for channel maintenance.
Can the 4DK adiabatic cooler reduce energy consumption and the carbon footprint of a plastic manufacturing plant?
Absolutely. The Ecodry 4DK is engineered to deliver outstanding operating efficiency, reducing energy consumption by up to 15% and improving the overall Coefficient of Performance (COP) by up to 30% compared to previous generations.
Utilizing next-generation EC (Electronically Commutated) motor technology and a newly developed streamlined airflow panel, it minimizes electrical draw. Additionally, during colder months, the system leverages free cooling to bypass energy-intensive chillers, significantly lowering the plant's overall carbon footprint and operating costs.
What are the installation advantages of the 4DK series for expanding plastic processing facilities?
The 4DK series features a highly modular, "Wide and Deep" design that provides exceptional power density in compact spaces, making it the perfect cooling tower alternative. It ranges from 2 to 20 fans per unit and features large stainless steel manifolds designed for Plug & Play parallel coupling, allowing for easy expansion as production needs grow.
Furthermore, it offers full self-draining (glycol-free) configurations for safe operation in freezing climates, ensuring 100% reliability and eliminating the environmental risks associated with antifreeze chemicals.
