How to Prepare Your Evaporative Cooling Equipment for Peak Season Performance
As summer arrives in full – and cooling system usage increases – we’re highlighting the importance of proactively maintaining your cooling media. Although many maintenance teams and facility managers schedule media inspections at this time of the year, looking for wear and scaling is just the beginning.
Media assessments, as well as replacement planning, are critical when it comes to preserving peak performance. Pre-season system cleaning (before the peak demand arrives) helps maintain efficiency, saves costs, and keeps water sustainability goals in focus.
In this article, our product team shines a light on the benefits of early summer maintenance, as well as on the many ways in which Condair’s engineering support and service teams can work with you to catch issues before they negatively impact performance and drive up unnecessary cost.
Understanding the Importance of Beginning of-Summer Inspections
As temperatures rise, evaporative cooling systems must handle greater thermal loads, which leads to increased runtime and additional demand on the media. By performing beginning-of-summer inspections, facility teams can catch issues before those peak loads arrive. Inspections like these, as well as cleanings, have a direct impact on both cooling performance and operational costs.
Symptoms of Media Degradation and Their Effects
Evaporative cooling media that has become partially clogged, damaged, or degraded can limit system performance and drive up overall energy use. Ensuring that your media is in optimal condition helps to prepare the cooling system to operate efficiently when it’s needed most.
Clean and intact media ensure proper airflow and consistent saturation, which leads to more effective cooling. At the same time, regular inspections help to:
- Avoid costly and/or unacceptable downtime
- Mitigate the risk of overworking compressors and/or backup systems
- Extend the lifetime of the media
It all adds up to optimal performance and tangible operational savings.
Visible Signs of Media Wear-Out
Maintenance teams and facility managers should look for the following signs of wear when inspecting their systems’ media:
- Brittle or crumbling media
- Streaking across the media
- Algae growth or visible scale build-up
- Sagging panels
- Noticeably reduced water absorption
Indicators like those listed above typically suggest that the media is no longer performing optimally and should be repaired, cleaned, or replaced.
Our Engineering Support and Service Teams Can Help
Condair’s engineering and service teams offer an even more advanced evaluation that goes beyond what a visual check can reveal. Assessing factors like pressure drop, airflow resistance, system performance metrics, and water quality, our team brings deep knowledge of evaporative system design and understands how media degradation affects overall system efficiency.
When & Why We Recommend Media Replacement
Our approach is always based on system performance and lifecycle value, and not just media’s visual appearance and/or its number of years in service. Evaporative media ages differently under different circumstances and operational loads. Therefore, all media must be evaluated and its viability assessed independently.
When to Replace
At Condair, we recommend full media replacement when it shows signs of:
- Structural breakdown
- Persistent clogging
- Mold or bacterial growth
- Consistent efficiency or pressure drop decline
When Not to Replace
We’ll also advise customers about when not to replace their media, for example:
- When it’s still structurally sound
- If the system is operating efficiently
- When any buildup can still be cleaned
The Importance of Media Replacement Planning
Condair supports proactive media replacement planning through our Engineering Services team and our End-of-Life (EOL) tool. The EOL tool considers critical variables including local water quality, system run-time, and environmental conditions to estimate the expected lifespan of cooling media at any specific site.
By modeling media performance over time, we can help customers understand when to plan for replacement, avoiding unexpected failures and maintaining optimal cooling efficiency.
Our proactive approach minimizes downtime, ensures budget predictability, and reduces operational risk, especially in mission-critical environments where downtime is unacceptable and performance and uptime are everything.
Properly Evaluating Media’s Condition Offers a Number of Solutions
Assessing the condition of your media, especially as consistently warmer temperatures arrive, ensures that your cooling system is always operating at peak performance, both in terms of efficiency and cost.
Taking a proactive approach before evaporative cooling systems are required to handle greater thermal loads enables service teams and facility managers to address issues before increased runtimes and additional demand affect the media.
