Recycle Evaporative Cooling Pads in Air Coolers

Evaporative coolers, commonly called swamp coolers, are gaining popularity as an energy-efficient and eco-friendly alternative to traditional air conditioning systems. By leveraging the natural evaporation process through water-saturated pads, these systems offer efficient cooling while reducing reliance on chemical refrigerants harmful to the environment. This comprehensive guide delves into the crucial role of quality evaporative cooling pads, explores the nuances of installation, and provides in-depth insights into maintenance, repair, and replacement procedures.

1. Understanding Evaporative Cooling Pads

Evaporative cooling pads are the unsung heroes behind the efficiency of evaporative coolers. Soaked in water, these pads play a pivotal role in the cooling process, making comprehending their types and functionalities crucial. Let’s explore the nuances of these pads before delving into the broader aspects of evaporative cooling.

1.1. Types of Evaporative Cooling Pads

Evaporative coolers predominantly use corrugated cellulose pads, with honeycomb pads, like those found in Mastercool and Aerocool systems, proving the most effective. The CELdek line, renowned for its patented, high-density cellulose paper treated to resist deterioration, elevates indoor air quality while meeting stringent UL Environmental GREENGUARD GOLD certification standards for emissions.

1.2. Efficiency in Dry Climates

Evaporative cooling exhibits heightened effectiveness in arid climates due to its unique ability to convert humidity into cooling. Understanding the science behind this process is pivotal. For every gallon of water absorbed by the pads, a significant 8,700 Btu of sensible heat is extracted from the air and converted to latent heat. This makes it a more efficient cooling method than alternatives in dry climates.

2. Evaporative Cooler Installation

Efficient installation is the cornerstone of optimal evaporative cooler performance. Before we dive into the details of installation methods and considerations, let’s understand the critical factors that come into play when setting up an evaporative cooling system.

2.1. System Design Considerations

Before installation, consulting with an experienced installer is crucial. This ensures the system is appropriately sized for your specific climate and needs, preventing the common pitfall of oversizing that could lead to unnecessary electricity consumption. A well-designed system not only optimizes energy efficiency but also overall cooling performance.

2.2. Location and Structural Considerations

The choice of installation location plays a pivotal role in the long-term functionality of the evaporative cooler. Ensure the proposed location supports the unit’s weight and fits through existing doors and windows. Proper planning at this stage prevents structural issues and contributes to the system’s overall efficiency.

2.3. Installation Methods

Understanding the two primary installation methods—central location or connection to ductwork—is essential. The selection between these methods depends on factors such as the size and layout of your home or business. Ducted systems, suitable for larger spaces, ensure uniform cooling throughout the area.

3. Evaporative Cooler Maintenance and Repair

Maintaining and repairing your evaporative cooler is essential for sustained efficiency. This section will delve into the necessary steps for regular maintenance and troubleshooting common issues. Before we get into the nitty-gritty of maintenance, let’s explore why these tasks are imperative for the longevity of your cooler.

3.1. Regular Inspection and Cleaning

Annual inspection and cleaning of evaporative cooling pads are critical to remove hard water mineral buildup that can diminish their effectiveness. The quality of pads is a significant factor in determining how often they require cleaning. Regularly checking the float valve to ensure proper water supply is equally important to prevent disruptions in the cooling process.

3.2. Troubleshooting Common Issues

A lack of cooling power is a common problem with evaporative coolers and is often attributed to clogged pads. Regular cleaning with a solution of vinegar and water can rectify this issue. A cracked reservoir or tubing or a misaligned float valve may cause leaks. Addressing these issues promptly prevents further damage and ensures the continued functionality of the system.

3.3. Professional Assistance

While many issues can be addressed through DIY maintenance, seeking professional assistance for persistent problems or complex repairs is advisable. Professional technicians can conduct thorough inspections, identify underlying issues, and perform necessary repairs, preventing major repair costs in the long run.

4. Evaporative Cooler Replacement

While regular maintenance can extend the life of your evaporative cooler, there may come a time when replacement is the best course of action. This section will guide you through a step-by-step process for replacing cooling pads and other components. But before we get hands-on, let’s understand when and why replacement becomes necessary.

4.1. Turning Off and Unplugging

Prioritize safety by turning off and unplugging your evaporative cooler before initiating the replacement process. This ensures a secure environment for both you and the equipment.

4.2. Front Panel Removal

Carefully remove the front panel, securing it with clips or screws to access the cooling pads. Take note of the pad dimensions for replacements and consider cleaning other components, such as pads or hoses, depending on your cooler type.

4.3. Pad Replacement

Gently pull out the old pads, making room for the new ones. Opt for high-quality replacement pads, such as those in the CELdek line, to guarantee efficiency, longevity, and compliance with environmental standards.

4.4. Choosing Quality Replacement Pads

Investing in quality replacement pads is essential for maintaining the optimal performance of your evaporative cooler. The CELdek line, with its honeycomb construction and resistance to fungi and bacteria, ensures superior efficiency and durability.


Recycling evaporative cooling pads in air coolers involves a multifaceted approach, encompassing an understanding of pad types, efficient installation, regular maintenance, and quality replacement. By following these comprehensive steps and seeking professional assistance when needed, users can maximize the efficiency and longevity of their evaporative coolers and contribute to a greener and more cost-effective cooling solution. In a world increasingly conscious of environmental impact, embracing such sustainable technologies becomes pivotal for a healthier and eco-friendly future.


How often should evaporative cooling pads be replaced?

The frequency of replacement depends on pad quality and room size. High-quality cellulose pads may last years, while low-quality pads may require seasonal replacement.

Can evaporative coolers be used in humid climates?

Evaporative cooling is more effective in dry climates, as it relies on converting humidity to cooling. However, they can still provide some cooling in humid conditions.

What is the significance of the CELdek line in evaporative cooling?

The CELdek line offers patented, high-density cellulose paper treated to resist deterioration, ensuring improved indoor air quality, minimal mildew growth, and adherence to environmental standards.
