By D Roy Choudhury, AVP, Desiccant Rotors International | The Machinist | May 21, 2024

Industry players are seeking cost-effective solutions for cooling their spaces in anticipation of the hot summer months. The article outlines why evaporative cooling is a viable option for effectively cooling large spaces, such as manufacturing facilities.

With the onset of summer, heatwaves remain a matter of concern among people. Adding to it, working in industrial plants compounds the heat problem as the spaces are inherently complex structures containing heavy machinery where critical processes are carried out. Considering the critical nature of these processes, they further contribute to the dissemination of a significant amount of heat. Predictions based on IMD reports indicate an impending heatwave expected to reach its peak between May and June, can further worsen the situation in an industrial plant setup. The heat within the facility can lead to deterioration of the products, which can immensely compromise the quality and jeopardise the profitability of the company. In addition to this, inadequate cooling owing to the complexity of the structure coupled with the rising temperatures can account for uncomfortable conditions, making the premises unsuitable for working. Additionally, prolonged exposure to excessive heat can lead to a phenomenon called heat stress among the occupants. Symptoms such as swelling, cramps, and exhaustion can also develop among the employees.

These factors collectively impede the productivity of the employees and interfere with the smooth functioning of the day-to-day operations. Therefore, to optimise the output of the plant, it is imperative to maintain the temperature within comfortable limits to boost the performance of the employees. However, cooling down the excess space in large facilities consumes a significant amount of energy. Moreover, with the impending sweltering summer,
industry players are seeking cost-effective solutions to efficiently cool their spaces. Industrial evaporative cooling emerges as the most viable solution for effectively cooling large spaces. Installing air conditioning can be challenging and costly, requiring a large number of systems and leading to high installation, maintenance, and operational costs. Conversely, evaporative cooling ventilates premises in the most economical way, with minimal capital costs for installation and setup prices just one-fourth of those for air conditioning systems. Industrial evaporative cooling provides a cost-effective solution by continuously utilising natural resources to cool spaces in an environmentally friendly manner. By extracting 100 per cent natural air from the surroundings, this mechanism ensures a continuous supply of oxygen to cool large industrial spaces while also eliminating fumes, odours, carbon dioxide, airborne impurities, and built-in dust. This circulation of fresh air reduces sultriness and removes stagnant indoor air, which is responsible for the proliferation of viruses and bacteria. Therefore, in addition to fulfilling the task of cooling down the plant, evaporative cooling plays a crucial role in enhancing the indoor air quality as well. Evaporative cooling significantly lowers temperatures by 10°C to 12°C by employing water-saturated cooling pads to filter out hot, dry air. This mechanism initiates water evaporation to form cool vapours, thereby providing a cooling effect. High-adsorbent materials are utilised to further enhance saturation efficacy, ultimately reducing the overall running costs of the machines. Consequently, there is a notable reduction in energy consumption, with evaporative cooling systems using 80 per cent less electricity compared to other cooling solutions on the market. Brands such as ARCTIC can proficiently achieve the required air quality and effectively cool spaces in a comfortable and hassle-free manner. Considering the wide array of advantages evaporative cooling offers, it has the potential to increase plant productivity. By improving employee comfort and concentration in hot conditions and ensuring optimal machine performance by preventing overheating, these cooling systems contribute to both employee well-being, safety, and operational efficiency within the plant.

The highly durable pads are well adept at converting the sensible heat to latent heat which ultimately results in supply of humidified and cold fresh air across the enclosed space.

Therefore, looking at the complexity of the manufacturing units, industrial evaporative cooling emerges as the most viable option to fuel the efficiency of the plant. It plays a crucial role in providing the occupants with cool, fresh air, enabling them to concentrate better at their work, and also aiding in minimizing the health risks due to hot and sultry conditions. At the same time, it also protects the integrity of the machines, which might get damaged due to overheating. As a result, by alleviating the various threats looming over the facility, the cooling mechanism comes with the proficiency to drive the productivity of the manufacturing units.

EcoCool Pads: Sustainable Cooling Solutions for Evaporative Cooling

When dealing with hotter seasons or living in warmer climates, animal farmers frequently face the issue of keeping their livestock cool and comfortable. High temperatures and humidity in barns can induce heat stress, a condition detrimental to the health of poultry, cattle, and pigs.

Amongst various cooling solutions, evaporative cooling pads – also known as cooling cells, stand out as a standard and practical choice. These systems harness the natural cooling properties of evaporation to lower air temperatures within barns. In this context, let’s delve deeper into how DRI’s EcoCool Pads operate and benefit farmers.

The pads, typically made from materials like cellulose, cardboard, or PVC, are at the heart of an evaporative cooling system. DRI’s EcoCool Pads are uniquely designed with a honeycomb structure to optimize water saturation and airflow.

Water is introduced into the pads, typically through a water pipe across the top. Any evaporated water is collected at the bottom and recycled back into the pads. This evaporation-centric cooling mechanism is a simple yet effective process reminiscent of how humans sweat to cool down.

When the warmer air contacts the cooler water in the pads, heat is transferred from the air to the water. This exchange induces water evaporation, consequently cooling the air. With EcoCool Pads, temperature drops of 10-20°F are standard, and in hot, dry climates, the cooling effect can be even more substantial.

EcoCool Pad systems are strategically designed to cool air as it enters the barn naturally. Usually, the system is installed ahead of intake fans that draw in external warm air. As this air traverses the pads, it is cooled by exchanging heat with the water. Other fans at the opposite end of the building draw the cooled air across the barn, creating a ‘cooling tunnel’ effect.

Cooling pads such as EcoCool are inherently safe

Given that they use water and natural evaporation, there’s minimal chemical leakage or cross-contamination risk. Moreover, they do not directly moisten the barn interior, mitigating potential health risks for the livestock. They’re also straightforward to clean, reducing the chances of mould, mildew, or mineral accumulation within the pads.

EcoCool Pads offer several advantages to farmers

These pads outperform other cooling systems in mitigating heat stress, particularly in ideal environments. They are cost-efficient and energy-saving, especially when paired with active ventilation. The pads promote green cooling, air pollution-free, and significantly reduce health risks by minimizing chemical and gas emissions. Moreover, they can be easily installed and maintained, and their utility spans a wide range of applications, from animal barns to greenhouses.

Using the concept of evaporative cooling

EcoCool Pads provide a fresh breeze of cool air by allowing warm or hot air to pass through their water-saturated surfaces, facilitated by a fan. This process evaporates water when the air meets the wet surface, cooling and humidifying the incoming air.

Benefits of DRI EcoCool Pads:

Cellulose Composition: EcoCool is made from a unique, cross-sectional fluted medium, specially processed to retain and absorb water, maximizing cooling efficiency.
Strong Form: The distinctive fluted structure of EcoCool is designed to prevent sagging and resist blockages.
