Cooling Tower
“It is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature” (Source: Wikipedia).
- Centrifugal cooling tower: device that uses a centrifugal fan to move the air which is necessary to perform forced evaporation. Generally preferred when there are noise problems, need for air ducting or when sound-absorbing silencers are needed.
- Closed-circuit cooling towers. Tower in which the process fluid which is cooled (often not water, but a cooling fluid) does not come into contact with the cooling water. This is distributed on the outer surface of a tube-bundle or of linked plates and circulates between the distributor and the basin.
- Crossflow cooling towers (against the current). Towers in which the air flow goes in opposing directions.
- Counterflow cooling towers. “In a counterflow design, the air flow is directly opposite to the water flow. Air flow first enters an open area beneath the fill media, and is then drawn up vertically. The water is sprayed through pressurized nozzles near the top of the tower, and then flows downward through the fill, opposite to the air flow” (Source: Wikipedia).
- Factory-assembled cooling tower: small and medium-sized, totally factory assembled in 2 or 3 main sections with dimensions that are compatible for road or sea transport. No assembly time or a few days for modular systems.
- Field-erected cooling tower. Generally large, in order to reduce transport costs. It is transported completely disassembled and assembled directly at the installation site. Assembly times are roughly variable between 20 and 60 days.
- Mechanical draft cooling tower. Evaporative cooler in which the water is cooled by partial evaporation through contact with a mechanically driven air stream.
- Open-circuit cooling towers. Evaporative system that cools water through direct exchange with air.
Our range of applications
Food Industry
Cooling technologies for food industry must help preserve the quality of the finished product (and of the process liquid): this is true even more than in other industries. Closed circuit cooling towers and “hybrid towers” can make their contribution. It is fundamental to grant the operational plant continuity of the cooling system.
Metalworking
Foundries, steel mills, aluminum production lines: the plant managers of these industries require operational continuity, significant thermal jumps in cooling and cost containment for management and maintenance. Remote management platforms are an ally.
Chemical and Pharmaceutical Sector
We are talking about systems of very different sizes: as industrial fluid temperatures change the cooler must be sized accordingly. The operational continuity is fundamental, while the good life of the cooler is particularly appreciated (also thanks to non-corrodible solutions). Noise is not a problem, thanks to sound-absorbing technical solutions.
Textile Industry and Tanneries
The demands of these industries are linked to the most variable temperature changes, depending on the single production process. An example is the drying of leather in tanneries, carried out thanks to vacuum pumps: the liquid ring of these tools is cooled by a cooling tower. Usually, dirty water is treated: for this very reason, open cooling towers with wide-passage exchange packs are suggested. The durability of the solutions adopted is appreciated: fiberglass is a plus.
Paper Mills
In this sector, high water flow rates best fit large industrial cooling towers. It is often required to transport the units over great distances: for this reason, it is advantageous to rely on modular and / or “container” solutions, which also reduce management and installation costs.
Plastic and Rubber Processing
The plastics industry has gradually become attentive to operating resource use optimization and environmental sustainability: this is why adiabatic cooling systems seem ideal. Sometimes output temperatures below zero are required: in these cases we go to ad hoc chillers for industrial processes.
Industrial Wastewater
The different phases of the industrial water treatment process require defined cooling temperatures in accordance with regulations. In this sector, it is preferable to use cooling towers with anti-clogging fill packs for industrial contaminated water.
Mechanical Industry
The mechanical industry includes the most diverse sectors, in addition to metal and plastic processing: compressors and test benches are significant examples. Required temperature differences and water quality vary greatly depending on the industry: evaporative cooling towers can be used, preferably open-circuit ones (with exchange packs for dirty or clean water depending on the context) and adiabatic coolers for consumption optimize.
Oil & Gas
These industries are characterized by very high water flow rates. Modular industrial cooling towers, easily transportable over long distances despite their large size, are often suggested together with large concrete field-erected cooling towers.
Offices
Low noise levels to ease daily life: this is the “must” of the cooling circuits attached to the air conditioning systems in the offices. Configurations suitable for restricted or peculiar spaces are also often required: the ideal are open circuit cooling towers with sound-absorbing technologies, possibly equipped with versatile centrifugal fans.
Healthcare Facilities
Hospital engineers pay attention to two fundamental needs: low noise level and simple maintenance to always keep equipment safe and efficient. Cooling technologies can meet these needs: evaporative and adiabatic coolers with sound-absorbing solutions, preferably with large accesses for internal inspections. The non-corrodible fiberglass can be a plus for useful machinery lifecycle extension.
Shopping Centers
The air conditioning systems in shopping centers must ensure low noise levels: the same goes for the attached coolers. Therefore, the engineering firms and plant installers are concerned with installing cooling solutions with sound-absorbing technologies, mostly evaporative. A further plus is the need to place the machine in confined spaces.
Tertiary Sector
Cinemas, theaters, buildings for public entertainment have the same needs as offices: the cooling units, attached to the air conditioning systems, must be silent and adapt to small spaces: also in this case, open-circuit cooling towers with sound-absorbing technologies are ideal. Centrifugal fans ensure space adaption, while non-corroding fibreglass extends product lifecycle.
Cold Chain
Foodstuff storage at temperatures below zero can be implemented through different types of natural or non-natural refrigerants: evaporative or adiabatic condensers can be indicated, depending on whether the company is focused on performance or resource use optimization. Low noise solutions are often appreciated.
Large-Scale Distribution and Supermarkets
Supermarkets and large-scale distribution are increasingly attentive to environmental sustainability: hence the choice to use natural refrigerants for chillers. In these cases, the adiabatic subcooler patented by MITA guarantees an extra step in efficiency: a solution that can be easily integrated into the system.
Refrigeration in the Food Sector
Refrigeration in the food sector is linked to production lines in food & beverage: the optimization of efficiency and resources (water and energy) are the most requested needs by customers. Evaporative and adiabatic condensers must be able to manage different refrigerant gases based on project requirements.
