Keeping microchannel heat exchangers (MCHEs) performing exceptionally over time isn’t a mystery—it’s about care, smart routines, and having the right knowledge. Let’s walk you through a maintenance journey that keeps your Aidear microchannel units running strong, clean, and efficient—no guesswork, just good craftsmanship.
These finely crafted exchangers pack tight channels that amplify performance—but they can also clog or degrade if neglected. Proper maintenance keeps heat transfer at peak and avoids costly downtime.
Start with soft tools—a vacuum with a soft brush or compressed air under 3–5 bar pressure works wonders. Brush along the fins gently; strong tools or pressures can bend or damage them.
Use water with a pH between 4.5–8.5 sprayed with a wide-angle nozzle from at least 400 mm distance. Always spray against airflow to dislodge dirt effectively.
Skip harsh acids or caustics—they erode aluminum and protective coatings. Use only neutral-pH, aluminum-safe cleaners, like specialized microchannel solutions that preserve coating.
Clean at least every six months—more often in dusty or corrosive environments. Shut down power and protect electronics before starting.
Remove debris with a soft vacuum or brush—no scraping. Keep motion parallel to fins to avoid damage.
Rinse thoroughly from inside out, keeping nozzle at a safe distance and at a gentle angle.
Remove residual water immediately: use fans, compressed air, or a soft blower to fully dry the exchanger and prevent damage.
Avoid pencil nozzles and pressure over 40 bar—these can permanently warp fins or ruin coatings. Use a wide-angle spray instead.
Harsh cleaners may look efficient, but they degrade aluminum or residue attract new dirt. Stick to neutral, aluminum-safe detergents.
No hard nozzle contact or scraping—these can dent metal and remove protective coatings. Handle with a light touch.
Aidear equips its microchannel exchangers with durable coatings and sturdy aluminum that stand up to frequent cleaning and abrasive environments.
Every system is unique. Aidear offers tailored cleaning guides and replacement parts that match your design and ensure lasting performance.
Track hidden buildup or coating wear with UV detection. It’s efficient, non-invasive, and catches subtle degradation early.
Systems that log performance metrics—like airflow or temperature shifts—can signal maintenance needs before efficiency drops.
Using proper cleaning cycles and gentle techniques keeps Aidear’s exchangers operating smoothly, with clients reporting stable performance in HVAC and industrial setups months longer than with untreated systems.
Regular, thoughtful care unlocks the full lifespan of microchannel heat exchangers. By cleaning gently, using the right tools, and leaning on Aidear’s expertise, your units stay efficient, clean, and dependable for years to come.
Q1: How often should I clean MCHEs?
About every six months—more if dust or corrosive environments are present.
Q2: Are mild aluminum cleaners okay?
Yes—as long as they’re neutral pH and designed for microchannels. Avoid anything acidic or caustic.
Q3: Can I use a pressure washer?
Only with a wide-angle nozzle, keeping pressure under 40 bar and 400 mm away, angled properly.
Q4: What if I see performance dips?
Dust, damp, and blocked fins are often the culprits—cleaning with this guide usually fixes it fast.
Q5: Does Aidear support cleaning tools or supplies?
Absolutely—they help you pick the right kits and provide custom maintenance advice for your exchanger.
