To complete the Ecodry System innovation, the cooling units installed at each process are connected to a Central Adiabatic Cooling System installed outdoors in order to reject the heat extracted from the processes to ambient (if not recovered). This modular system – an alternative to old-style evaporative cooling towers - is made of closed circuit adiabatic fluid coolers with large copper coils and aluminum fin heat exchangers and inverter driven EC-brushless fans. This system can keep the coolant temperature even lower than the ambient temperature, thanks to the InternationallyPatented Adiabatic Chamber which, during high ambient temperature conditions, pre-cools the air before it reaches the heat exchangers.
Obviously, this central system can also provide direct cooling to all processes requiring temperatures above ambient, such as air compressors, cooling tunnels, pasteurizers, etc.
The new ECODRY SYSTEM brings overall performance to a higher level in beverage manufacturing, based on: Increased Productivity,highly Reduced Operating Cost and Total Modularity.
Reduced Operating Costs:
The "ECODRY SYSTEM" achieves remarkable running cost savings when compared to traditional central systems: Energy Savings (up to 30%), Water Savings (up to 95%) and overall Maintenance & Safety Costs Savings (up to 90%).
Energy Savings (up to 30%)
The new system based on individual cooling units for each process, results in very high energy savings due to four main reasons:
Higher overall refrigeration performance of the system (EER/COP).
According to the requirements of the different processes in the facility each dedicated refrigeration unit will operate at a specific coolant temperature, thus running each process consistentlyat the maximum refrigeration circuit performance level. Whenever the process may run a product that allows a higher coolant temperature,the unit associated with that line will automatically increase its efficiency. Additionally, this new concept consumes no energy - of any kind – when there’s no production.
Higher refrigeration efficiency of cooling units (EER/COP).
All units have the latest generation of high efficiency, variable speed refrigeration screw compressors and frequency driven pumps, resulting in remarkable efficiency, especially under partial load conditions. Additionally, for those processes with high temperature differential (difference between temperature of coolant returning from the process and temperature of coolant supplied to the process), the cooling units have Multi-Stage-Cascade refrigeration, further improving efficiency.
Water Savings (up to 95%)
This consept uses a central Adiabatic Cooling System for heat rejection of the whole thermal load of the plant. This technology operates water evaporation only during short periods of time whenever ambient temperature is extreme (above 30°C). An “on demand” Intelligent Saving Software operates adiabatic mode only when needed. Otherwise, the system runs completely dry.
Maintenance & Safety Costs Savings (up to 90%).
The refrigeration units are made of relatively small chillers, which require low expertise to maintain or repair. The chillers are built with leak-free refrigeration circuits, which makes them almost maintenance free. Operating with innocuous gases, they do not require any specific safety infrastructure, saving all costs involved, including safety insurance policies.
This Modular, Plug & Play Concept has many additional advantages compared to traditional systems. It is easily expandable at any time, which allows the installation of the precise capacity needed at every stage of the plant growth.
The Ecodry System achieves outstanding results in terms of environmental impact reduction. The main advantages are:
Reduced “CARBON FOOTPRINT” - up to 50% less
Almost no “WATER FOOTPRINT” - up to 95% less
Lowest “RISKS OF EMISSIONS”
The system is Ammonia free, utilizes innocuous refrigeration gas with the lowest GWP available today and is divided into several separated small circuits. So the risk of emissions in the case of leakage is reduced to a minimum.
Frigel group offers innovative cooling solutions and refrigeration equipment for industrial applications. All Frigel products are conceived and engineered in the headquarters in Florence, Italy with the latest technologies available in the field and then built in four manufacturing facilities around the world. The solutions are design to fit all specific cooling and temperature control requirements in multiple industries, such as plastics, beverage, oil & gas, cogeneration & tri-generation, food, chemical, pharmaceutical, metals, die-casting & furnaces, data centers and others.
In the last 20 years, Frigel has become a market leader in several of these industries introducing a new way of conceiving and making refrigeration, which is called “intelligent process cooling”. Focused on constant innovation, Frigel designs and builds integrated cooling solutions that achieve: unique performance for each specific application and, at the same time, setting new sustainability standards for the industry
Frigel has been the pioneer in introducing the Ecodry System (internationally patented). A close circuit adiabatic cooling system for overall heat dissipation (replacement for old evaporative cooling tower technology). With it’s exclusive “Adiabatic Chamber” design, Ecodry is the most efficient adiabatic cooling system available and has been successfully validated worldwide in more than 8.000 installations and in all weather conditions.
Frigel also manufactures a wide range of products in the field of refrigeration and process temperature control. Such as high efficiency air and water cooled chillers and heat pumps, from portable units up to several large central systems with inverter driven high efficiency screw compressors. All systems are designed to achieve the highest standards of efficiency and respect of environmental norms.
