As we exit the heating season, many commercial rooftop units (RTUs) and chillers are carrying a winter’s worth of salt, dust, and atmospheric debris. While these contaminants might seem minor, they act as a thermal insulator, forcing your system to work significantly harder to move heat.
The Math of Dirty Coils
In an industrial setting, efficiency isn’t just about “being green”—it’s about overhead.
- Increased Head Pressure: Dirty condenser coils increase the temperature of the refrigerant, leading to higher head pressure. This can increase energy consumption by up to 30%.
- Reduced Cooling Capacity: A layer of grime just 1/100th of an inch thick can reduce a coil’s heat transfer efficiency by 21%.
- Component Longevity: High pressures and temperatures caused by dirty coils are the leading cause of premature compressor failure in commercial units.
AirTrack’s Industrial Approach
We don’t just “hose down” your units. Our industrial coil maintenance includes:
- Chemical Neutralization: Using specific non-acidic cleaners to break down industrial greases and salts without etching the aluminum fins.
- Fin Straightening: Repairing “folded” fins that restrict airflow, often caused by winter storms or high-pressure washing.
- Performance Baseline: We measure the pressure drop across the coil before and after cleaning to provide you with a tangible “Efficiency Gain” report.
Call to Action: Don’t let invisible dirt drive up your summer power bills. Contact AirTrack HVAC to schedule a comprehensive coil restoration for your facility’s cooling plant.
