Microchannel coils, a recent advancement in the HVAC/R industry, have been widely accepted for their various benefits. These coils are making systems more efficient, compact, and cost-effective -but still come with their own set of challenges.
What are Microchannel Coils?
Microchannel coils are heat exchangers used in many evaporator and condenser applications. They are easily identifiable by their flat tubes and wave-like fins. These coils are made up of three main components: channels or tubes, aluminum fins, and two manifolds.
Advantages of Microchannel Coils
Microchannel coil technology offers several advantages that contribute to its growing popularity:
- Increased Efficiency: Due to their design, microchannel coils offer high heat transfer rates.This makes HVAC/R equipment more efficient, leading to energy savings.
- Reduced Size and Weight: Microchannel coils are lighter and smaller than traditional coils, reducing the overall weight and footprint of HVAC/R equipment.
- Lower Refrigerant Charge: Microchannel coils require a significantly lower volume of refrigerant, reducing environmental impact and operating costs.
Microchannel Coils in Various Applications
Microchannel technology is being utilized across a wide range of system designs:
- Chillers: In comfort cooling and process cooling, microchannel coils are being used to increase energy efficiency and reduce the chiller’s footprint.
- Rooftop HVAC Systems: Custom rooftop systems use microchannel coils as condensers, evaporators, and reheat coils.
- Data Center Cooling Systems: Microchannel coils are being used in data center cooling systems, providing energy efficiency.
Why Do Microchannel Coils Fail?
Despite their advantages, microchannel coils have experienced high failure rates in certain systems. These failures have been attributed to various factors, including manufacturing defects and inherent design issues. Furthermore, because microchannel coils hold a relatively small volume of refrigerant, altering the charge by even a few ounces can affect system longevity.

How is an Evapco MicroChannel Replacement Coil Different from an OEM MicroChannel Coil?
Non-Automotive, Industrial Design
Evapco MicroChannel Replacement Coils are designed specifically for industrial applications. Unlike OEM MicroChannel Coils, which are often based on automotive designs, Evapco coils are built to withstand the rigors and demands of industrial environments. This means they’re more robust, reliable, and suitable for heavy-duty use.
25-30% Thicker Tube Walls
One major difference between Evapco and OEM MicroChannel Coils is the thickness of their tube walls. Evapco’s tubes are 25-30% thicker, providing them with superior strength and durability. This makes them less susceptible to damage during installation and operation, and ensures they last longer.
Epoxy Coating for Superior Corrosion Protection
Evapco MicroChannel Replacement Coils come with an epoxy coating, offering superior corrosion protection. This means they’re better equipped to resist the corrosive effects of environmental factors, ensuring their longevity and maintaining their performance over time.
Lower Refrigerant Pressure Drop
Evapco’s design also results in a lower refrigerant pressure drop, which enhances operational efficiency. This is important for maintaining optimal system performance and reducing energy consumption.
Built-in Mini-receiver
A unique feature of Evapco MicroChannel Replacement Coils is their built-in mini-receiver, located in the lower header. This makes it easier to charge the system, simplifying the installation and maintenance process.
Side Flange for Easy Installation
Evapco MicroChannel Replacement Coils are designed with a side flange, making them easy to install. This drop-in/slide-in feature reduces installation time and ensures a secure fit.
5-Year Warranty
Finally, Evapco stands behind the quality of their products with a 5-year warranty. This gives you peace of mind, knowing your investment is protected.
