OEM vs. Aftermarket Parts: Which Is the Best Choice for Your Cooling Tower?
Choosing the right parts for a cooling tower installation is more than a purchasing decision. It directly impacts system performance, reliability, and long-term operating costs. Facility managers and engineers across Arkansas often face the same question: Should we use OEM or aftermarket parts?
The answer depends on your system goals, timeline, budget, and performance requirements. In this guide, we’ll break down the differences, explain when each option makes sense, and help you make an informed decision that supports long-term efficiency.
What Are OEM and Aftermarket Cooling Tower Parts?
Before comparing options, it’s essential to understand the distinction.
OEM (Original Equipment Manufacturer) parts are produced by the same manufacturer that built your cooling tower, brands like Marley, Baltimore Aircoil (BAC), or EVAPCO. These parts are designed specifically for your equipment model and meet the original engineering specifications.
Aftermarket parts, on the other hand, are manufactured by third-party suppliers. They are designed to be compatible with multiple cooling tower brands and models, often at a lower cost and with faster availability.
Both options can be effective when selected correctly, but they serve different needs.

When OEM Parts Are the Right Choice
OEM parts are often the preferred option for facilities that prioritize precision, longevity, and manufacturer compliance.
Because OEM components are built to exact specifications, they offer a seamless fit and predictable performance. This is especially important for new installations, critical systems, or facilities operating under strict compliance standards.
OEM parts are also commonly required when:
Maintaining manufacturer warranties
Working with newer or proprietary systems
Ensuring consistent performance across the entire system
For facilities investing in a long-term solution, OEM parts help reduce risk and support system reliability over time.
💡 HSSR tip: If you’re planning a complete system replacement or upgrade, we recommend OEM components as part of a complete cooling tower installation service tailored to your facility’s needs.
When Aftermarket Parts Make Sense
Aftermarket parts can be an innovative solution in the right scenario, particularly when speed, availability, or budget flexibility are top priorities.
Many aftermarket manufacturers offer high-quality components that meet or exceed performance expectations, especially for:
Aging systems outside of warranty
Emergency repairs or unplanned downtime
Facilities looking to extend system life without full replacement
In Arkansas, where weather conditions and seasonal demand can impact lead times, aftermarket parts often provide faster sourcing and reduced downtime. This is a key advantage for manufacturing plants, hospitals, and commercial facilities.
When selected and installed properly, aftermarket parts can deliver strong performance while keeping maintenance costs under control.
Key Factors to Consider Before Choosing
Rather than focusing only on price, decision-makers should evaluate the bigger picture:
1. System Age and Condition
Newer systems often benefit from OEM components, while older towers may perform just as well with aftermarket parts.
2. Performance Requirements
Facilities with high thermal loads or continuous operation may require OEM precision to maintain efficiency.
3. Lead Time and Downtime Risk
If your system is down or at risk of failure, availability may outweigh brand preference.
4. Long-Term Cost of Ownership
Lower upfront costs don’t always mean lower lifecycle costs. A trusted partner can help assess both.
Why the Right Parts Choice Impacts System Performance
Cooling tower performance is closely tied to heat transfer efficiency, airflow, and water distribution. Poorly matched components can lead to issues such as vibration, uneven cooling, or premature wear.
As discussed in our article on cooling tower maintenance warning signs, small component issues often escalate into major system problems when not appropriately addressed.
Choosing the right parts, OEM or aftermarket, helps prevent:
Reduced thermal efficiency
Increased energy consumption
Unplanned shutdowns
