Sustainable Cooling

2. We use water in a "circular" way, respecting its natural cycle

Water is the process fluid that we have been cooling since 1960, as well as being the useful element for increasing plant efficiency. We manage water in a circular way, that is, by suggesting solutions for its use and subsequent recovery, according to the following scheme:

The water cycle in adiabatic cooling

• Approximately 0.2 percent of the mass to be cooled evaporates, thus returning to the environment (typically in medium-hot periods a specific section is sprayed with water to reduce the air temperature).

The water cycle in evaporative cooling

• About 2% of the mass to be cooled evaporates, thus returning to the environment.
• About 1 percent of the mass to be cooled is disposed of in the network to maintain the correct concentration of salts in the circuit. The determination of this value is closely related to the quality of the treated water.

In terms of the following schematic, however, the systems proposed by MITA Cooling Technologies are located within the boxes highlighted in red. Wastewater treatment (part highlighted in yellow), on the other hand, is handled by another company part of the MITA Group (www.mitagroup.it): MITA Water Technologies (www.mitawatertechnologies.com). The goal is to make human use of the water resource as close as possible to the natural water cycle.

3. We also offer remanufactured systems and work on carbon footprint reduction

We are focusing on a careful choice of materials to be used in the construction of our machines: this is through research into components that encourage recycling at the end of their life: this is also how we can provide green cooling solutions. All this also involves the involvement of our suppliers. The goal is threefold:

• reduce the energy used in their production,
• increase the renewable component (self-produced or purchased),
• increase the second raw material component.

In addition, we provide remanufactured cooling systems: a new offering, sustainable for the environment and beneficial for the customer due to the lower use of energy and raw materials.

Not only that. Upon request, we can provide add to the analysis of the most optimized solution also the carbon footprint impact: all projects can be accompanied by LCA analysis, electricity use and water use.

We suggest PLC management (inverter system) for all machines for savings in the order of 80 percent over lifecycle. In addition, complete water treatment systems are undoubtedly a good practice.

4. How we select the most sustainable cooling solution

We analyze and select the most suitable solution and service to improve the environmental impact in cooling production processes, including with the support of advanced comparison and optimization softwares.

Each solution, if selected carefully and according to project needs, can bring savings in resource use and be environmentally sustainable and cost-effective.

Here’s how.

Dry Cooler

• No use of water to facilitate heat transfer (i.e., cooling of the process fluid).
• 100% use of electricity to move air (the only cooling carrier) through one or more fans.
• It is among the product categories that MITA is able to regenerate.
• Indication of “carbon footprint” by the MITA team.

Adiabatic Dry Cooler

• Minimal use of water (only for adiabatic operation), which is useful for facilitating heat transfer (i.e., cooling of the process fluid).
• Optimized energy use (higher efficiency due to adiabatic supply).
  Smaller installation spaces compared to the 100% air solution.
• It is among the product categories that MITA is able to regenerate.
• Indication of “carbon footprint” by the MITA team.

Evaporative Cooler

• Use of water for efficient heat transfer (i.e., cooling of the process fluid.
• Low and further optimizable energy use.
  Extremely small installation spaces.
• Falls within the product categories that MITA is able to regenerate.
• Indication of “carbon footprint” by the MITA team.

Industrial Chiller

• Use of electrical energy only for refrigerant gas compression and the use of one or more fans for the refrigerant condensing phase (in the case of air-cooled machines); possibility of “free-cooling” solutions.
• Use of electricity for refrigerant gas compression and water for the condensing phase of refrigerant gas (in the case of water-cooled machines).
• Extremely small installation spaces.
• It is within the product categories that MITA is able to regenerate.
• Indication of “carbon footprint” by the MITA team.
