Adiabatic Cooling Systems

1. Addressing cooling challenges in industries and HVAC/R

As a Production Manager or Technical Consultant, you are constantly under pressure. You need to ensure uninterrupted operations, reduce energy consumption, comply with increasingly stringent environmental regulations, and control operating costs. Many methods of process fluid cooling involve high water usage, soaring energy bills, and significant maintenance burdens, especially during peak thermal periods. Perhaps you find yourself managing…

• Continuously rising energy costs that impact your margins?
• Concerns about water management for cooling: availability, treatment, and disposal?
• The need for reliable cooling performance, even on the hottest days of the year?
• Pressure to adopt more sustainable and eco-friendly cooling solutions?
• Existing systems that struggle to meet your needs, leading to reduced efficiency or, worse, process downtime?
• Finding a cooling system that offers a low Total Cost of Ownership (TCO) without compromising on performance?

If these challenges sound familiar, MITA’s adiabatic cooling systems offer a proven, intelligent, and resource-saving alternative. We understand that you are not just looking for a piece of machinery, but a reliable cooling partner capable of understanding the specific needs of your processes, from industrial manufacturing to critical HVAC environments like data centers.

2. Adiabatic dry cooler: how smart cooling works

What is an Adiabatic Cooling System? An adiabatic cooling system cools water (or refrigerant gas, in the case of adiabatic condensers) using outside air, which is pre-cooled with water (air humidification) during the hottest periods of the day and year.

• Dry Operation: Primarily intended for the winter/autumn period. Outside air is drawn in and directed towards the finned coils containing the fluid to be cooled. The humidification process is deactivated, so there is no water involved, the humidifying pack (the section the air passes through to lower its temperature) is dry, and the humidification pump circuit is disengaged. Temperature probes, at the outlet of the cooled fluid and inside the machine, modulate the fan(s) speed to optimize energy use.
• Adiabatic Operation: Primarily intended for the summer/spring period. Outside air is drawn in and directed towards the finned coils containing the fluid to be cooled after passing through the humidifying pack (the adiabatic section) to lower its temperature. The pack is sprayed by short wetting cycles activated by a pump. Mains water is pre-loaded to activate the adiabatic cooling process. The adiabatically cooled air (therefore at a lower temperature than the outside air) is directed towards the finned coils, thus increasing the cooler’s efficiency during the hottest time of the year.

Different names, same principle. You will find this technology referred to as:

• adiabatic air cooler,
• adiabatic dry cooler or air-cooled adiabatic dry cooler,
• adiabatic cooler or industrial adiabatic cooler,
• adiabatic fluid cooler,
• hybrid adiabatic cooling system,
• adiabatic tower or adiabatic cooling tower (in these cases too, the terms are improper).

3. MITA Adiabatic Cooling Systems: cooling liquids or condensing gases

For processes that require efficient cooling of water or other process fluids, MITA adiabatic systems represent a more resource-optimized alternative to traditional dry coolers, primarily thanks to their exceptionally low water usage. Designed to offer superior performance even during the hottest times of the year, these systems intelligently activate their adiabatic pre-cooling only when strictly necessary, also eliminating the need for complex water treatments.

For the heat dissipation of even large-scale systems, PAD-XL W offers thermal capacities of up to 2,500 kW and can be configured with up to 20 fans over a length of 11.6 meters. This system is Plug & Play, ensuring ease of handling and rapid installation. It uses short, on-demand wetting cycles and an integrated system for recovering the wetting water; furthermore, it employs simple mains water that may not require treatment. The operating logic is governed by a PLC that optimizes the EC fans. The efficient design of the V-coil and the humidifying pack ensures high performance and simple maintenance. An ideal cooler for those seeking minimal water use and simplified management.

For small-scale systems, with contained thermal capacities (20 kW to 50 kW), optimized cooling has an ally in PAD-XS: its compact, low-footprint design makes it suitable for limited spaces. Here too, operation is automated with EC fans and regulation of the wetting cycles. It directly uses mains water without the need for specific treatments, with minimal and seasonal usage. PAD-XS is easily integrable into existing systems and, like all MITA industrial coolers, can be designed and configured to support remote control, monitoring, and data collection.

Both models guarantee minimal water usage and optimized energy use thanks to the advanced logic of the control panel. They also require a smaller installation footprint compared to 100% air-cooled solutions. They are regenerable products and contribute to reducing the carbon footprint.

4. MITA Adiabatic Coolers: key specifications and components on all equipment

These are the specifications that clients in the industrial and HVAC/R sectors will find in every MITA adiabatic cooler from the PAD-XL and PAD-XS ranges.

Advanced operating logic. Along with various sensors and a specific controller, it modulates the fan speed and the very short wetting cycles of the adiabatic section (about 15 seconds every 15 minutes during the hottest periods), avoiding the constant “waterfall” required by other solutions.

Water recirculation kit. Useful for recovering every drop needed for humidifying the adiabatic section. Short wetting cycles to humidify the adiabatic section, only when necessary. Integrated wetting water recovery kit and logic.

Adiabatic section. Two types of adiabatic panels: flocked PVC or the more common cellulose pack. We will evaluate together the best solution for your context. Short wetting cycles to humidify the adiabatic section, only when necessary.

The result is a guarantee of optimized energy efficiency and significant water savings, drastically reducing operating costs thanks to intelligent PLC controls. These systems also offer simple and reduced maintenance. No water treatment is required.
