High-Efficiency Fan Wall Systems for Industrial and Commercial HVAC

Fan walls replace traditional single large fans with multiple smaller, direct-drive fans arranged in a modular array. This design improves airflow efficiency, redundancy, and flexibility, making them an increasingly popular choice for both new construction and retrofit projects. Unlike conventional fan systems, fan walls maintain performance even if an individual fan module is offline, ensuring consistent operation in critical environments.

These systems deliver superior performance in applications such as:

  • Data Centers & Mission Critical Facilities: Continuous airflow to protect equipment and prevent downtime.

  • Industrial Manufacturing: Stable environmental control for production areas with variable heat loads.

  • Healthcare & Laboratories: Precise airflow management for infection control and cleanroom compliance.

  • Education & Commercial Buildings: Energy-efficient air handling in high-occupancy spaces.

  • Retrofits & Upgrades: Modernizing existing air handlers for better efficiency and reliability without full replacement.

How Fan Wall Systems Work

A fan wall is a bank of smaller, high-efficiency fan modules operating in parallel. Each fan is driven by its own motor, and the system is controlled to deliver the required total airflow. By distributing the workload across multiple fans, the system optimizes performance, reduces noise, and minimizes energy waste.

Core Features of Fan Walls:

  • Modular Fan Arrays: Easily scalable to match airflow and static pressure requirements.

  • Direct-Drive EC Motors: High efficiency, variable speed, and reduced maintenance compared to belt-driven fans.

  • Redundancy: If one fan fails, others automatically adjust to maintain airflow.

  • Uniform Airflow: Even distribution reduces hot spots and improves coil performance.

  • Compact Design: Fits into tight mechanical spaces and facilitates easier installation.

Matching the System to the Application

Selecting the right fan wall design depends on space constraints, airflow requirements, static pressure needs, and energy goals. Lincoln Associates partners with leading fan manufacturers to deliver systems that meet your exact specifications.

Fan Wall Options Include:

  • New AHU Installations: Fully integrated fan walls in factory-built air handling units.

  • Retrofit Kits: Custom-engineered modules to replace aging or inefficient fans in existing units.

  • Indoor & Outdoor Configurations: Flexible designs for varied installation environments.

  • Specialized Applications: Explosion-proof, high-static pressure, or low-noise designs for unique operational needs.

Tube Diameter

Use a caliper or tape measure to determine the outside diameter of the tubes.

If necessary, remove insulation to see the incoming and outgoing lines. Measure the diameter of the outside of the line to help determine connection size.

Standard connection types are MPT (male pipe thread), FPT (female pipe thread), and Copper Sweat Connection. MPT is threaded on the outside, FPT is threaded on the inside, and Copper Sweat is used for soldered connections

Fins per Inch

Using a ruler, count the number of fins on the coil within one inch. Normal fin counts will be between 4 and 14 FPI.

Fin Length

Measure in the direction of the tubes, regardless of which direction the tubes are running.

Fin Height

Measure in the direction of the fin.

Single, Double, and Half Serpentine

Rows are counted in the direction of airflow, no matter how the coil is installed. You can count rows by looking at either the header end or the return bend end of the coil. Note that headers or return bends may not be evenly spaced across the coil.

Fluid coils—hot water, chilled water, and glycol water—regulate building air temperature by heating or cooling air in Air Handling Units (AHUs). Constructed with multiple rows of tubes, typically copper, these coils efficiently transfer heat between air and circulating fluids. They are vital for year-round comfort, accommodating diverse fluids like glycols and thermal oils for varied HVAC needs.

Condenser coils transfer heat from refrigerant vapor to the outdoor air, ensuring efficient cooling in HVAC and refrigeration systems. Constructed from materials like copper or aluminum to maximize heat transfer, these coils are vital for maintaining precise temperature control in industrial and commercial environments.

Steam coils utilize the latent heat of steam, released during condensation from vapor to liquid. They feature efficient condensate management to prevent water buildup and ensure uniform steam distribution. Available in configurations for high and low-pressure applications, steam coils are highly effective for heating air in a wide range of environments.

Evaporator coils absorb heat from indoor air to cool and dehumidify spaces by evaporating refrigerant from liquid to vapor. Located indoors, these coils are essential for maintaining comfortable environments in industrial and commercial settings, offering excellent performance in cooling, process cooling, and dehumidification applications. They are versatile for use in Air Handling Units (AHUs), central systems, or duct installations.
