Selecting the Best Industrial Cooler
What factors should I consider when choosing the best industrial cooler for my needs?
Choosing the best industrial cooling system depends on several factors. Among them: the required cooling capacity.
Read all FaqHow is an industrial cooler sized and cooling capacity calculated?
The required cooling capacity, and the consequent sizing of the cooling system, can be calculated by an engineer experienced in industrial cooling.
Read all FaqAre there tools for “objective” industrial cooling system selection, such as calculation software?
Yes, there are calculation and sizing software: some manufacturers and cooling consultants use them in recent years to make a selection that is as tailored as possible to the needs of the individual project.
Read all FaqWhat are the questions I need to ask an industrial cooling expert?
This is not something to worry about: the cooling consultant knows the right questions to ask for the selection of the best cooler, supported also by advanced software for calculation, selection, and resource optimization.
Read all FaqWhat are the costs of a consultation with an industrial cooling expert?
Pre-order consultation with an industrial cooling expert is often free of charge: consultant and customer can then jointly evaluate the selection of a cooler, based on specific project needs.
Read all FaqWhat are the special features of each type of industrial cooler?
Each type of industrial chiller has its own distinctive characteristics. In general, air cooling has lower efficiencies than other systems, especially in warmer seasons. In contrast, evaporative systems (wet cooling towers and evaporative gas condensers) have higher efficiencies.
Read all FaqWhat are the different types of industrial coolers available?
There are several types of industrial cooling systems. These include: cooling towers and adiabatic coolers.

How does an evaporative cooling system work?
All evaporative cooling systems use the evaporation of a small amount of water to lower the temperature of the larger mass of water. There are three main types of evaporative cooling systems: open circuit cooling towers, closed circuit cooling towers, and evaporative condensers.
Read all FaqHow does an adiabatic cooling system work?
An adiabatic cooling system (liquid adiabatic dry cooler, gas adiabatic condenser) is a system that combines the principle of a dry cooler with adiabatic pre-cooling of outside air.
Read all FaqWhat are the commonalities between evaporative and adiabatic cooling?
Evaporative and adiabatic cooling both take advantage of air to lower the temperature of a process fluid (water, water and glycol, gas).
Read all FaqWhat are the differences between evaporative and adiabatic cooling?
The main difference between the two systems is the way cooling itself takes place, especially in the different use of water and energy: both in terms of process and the amount of resources used.
Read all FaqWhat are the main components of an evaporative cooling system and an adiabatic cooling system?
The structure and components of the two systems are, of course, a consequence of the two different operating principles.
Read all FaqWhat are the advantages of evaporative cooling?
In summary: high cooling efficiency, low operating costs, and others related to the operation of the technology.
Read all FaqWhat are the use cases for adiabatic cooling?
Adiabatic cooling systems (adiabatic dry coolers for liquids, adiabatic condensers for gases) are the optimal solution where the goal is to save water, either due to the absence of that resource or to risks associated with its management.
Read all FaqWhich system is best suited to my needs?
Choosing the system best suited to your needs depends on several factors, mainly related to the specifics of the individual plant project to be developed: an exchange of information with a cooling consultant is often helpful.
Read all FaqWhat are the use cases for evaporative cooling?
Wherever there is a process fluid to be cooled, up to a temperature of a few degrees above the wet bulb temperature of air, an evaporative cooling system can be used.
Read all FaqWhat are the advantages of adiabatic cooling?
Some main advantages can be enumerated, related to reduced water use and optimized operation during different seasons and times of the day.
Read all FaqOpen- and Closed-Circuit Cooling Towers
What principle is exploited by open- and closed-circuit cooling towers?
Both open-circuit and closed-circuit towers exploit a very efficient operating principle: forced evaporation of a minimum amount of water causes a lowering of the temperature of the main water mass.
Read all FaqWhat is the main difference between open and closed circuit cooling towers?
The difference between the two systems lies in the different type of circuit exploited for cooling the process fluid.
Read all FaqD’autres systèmes de dissipation de la chaleur exploitent-ils le principe de l’évaporation ?
Les condenseurs évaporatifs fonctionnent de la même manière que les tours de refroidissement en circuit fermé. La seule différence réside dans le fluide de traitement, qui est un gaz réfrigérant.
Read all FaqWhat are the advantages of closed-loop evaporative cooling towers?
Among in main advantages: no contamination of the primary circuit and reduced risk of freezing by being able to insert ethylene glycol into the circuit, for example.
Read all FaqWhat are the main components of an open or closed tower?
Based on the partially different operating principle, there are some common and some peculiar components of the two types of evaporative cooling systems.
Read all FaqWhat are the costs of an open- or closed-loop cooling tower?
They vary according to type, capacity, and specific characteristics: from a few thousand euros to hundreds of thousands.
Read all FaqWhat are the advantages of open-circuit evaporative cooling towers?
In summary: Low installation and maintenance costs and very high cooling efficiency.
Read all FaqAlchemist Adiabatic Subcooler
What is subcooling in refrigeration systems and how can it be achieved?
Subcooling is the reduction of the temperature of the refrigerant leaving the condenser.
Read all FaqWhat benefit does subcooling bring to the refrigeration cycle?
Subcooling results in an increase in the cooling capacity of the system, hence electrical savings and a higher COP (coefficient of performance).
Read all FaqWhat is Alchemist, the adiabatic subcooler?
Alchemist is a patented solution from MITA Cooling Technologies that combines the useful effect of subcooling with the natural and efficient operating principle of an adiabatic cooler in a single device.
Read all FaqHow does Alchemist, the adiabatic subcooler, work?
A fan draws in a portion of air from the outside environment and then runs it through a finned coil inside which circulates the refrigerant to be subcooled.
Read all FaqWhat refrigerants can Alchemist handle?
Alchemist can be used with any type of refrigerant.
Read all FaqWhich sub-cooled refrigerant gives particular advantages?
The thermophysical characteristics of R744 make this refrigerant perfect for subcooling.
Read all FaqWhy choose Alchemist over a common adiabatic gas cooler in a system with R744?
An adiabatic gas cooler must adiabatically cool the entire air flow rate of the gas cooler itself, Alchemist works only on the subcooling air flow rate.
Read all FaqWhere to use Alchemist?
Downstream of a gas cooler in R744 systems, we have several references in commercial refrigeration, or combined with a refrigeration unit.
Read all FaqWhat maintenance does Alchemist require?
Alchemist is designed to bring efficiency to the system, which is why it does not require frequent or special maintenance operations.
Read all FaqWhat are the requirements associated with installing a subcooler?
Availability of mains water and a discharge point, an electrical connection, and a junction between the Alchemist coil and the refrigerant line.
Read all FaqIs the subcooler a sustainable solution?
Certainly. The subcooler is an environmentally sustainable solution because it provides an efficiency "boost" with each installation (COP increase).
