Industrial & Commercial Air Turnover Units

Keeping large facilities like warehouses and manufacturing spaces comfortable year-round is no small feat. Traditional systems can struggle with uneven heating or cooling, leaving some areas sweltering while others stay chilly. That’s where air turnover units come in—a smart solution that keeps air moving and temperatures steady without putting a strain on energy use.

At Lincoln Associates, we know that not every facility fits into a standard HVAC mold. Our air turnover systems are built to match the demands of your space.

What Are Air Turnover Units?

Air turnover systems (also called air rotation systems) offer steady, low-speed air circulation designed for large facilities with high ceilings. These units pull air from the floor, heat or cool it, filter it, and then send it back out through high-mounted discharge grilles. The result? A consistent indoor environment without wasted energy.

What they deliver:

  • Steady temperatures throughout the facility, even in hard-to-reach zones
  • Cleaner air by mixing in fresh outdoor air with every cycle
  • Better efficiency, using high-volume, low-speed fans that do more with less

At Lincoln Associates, we make sure every system is properly installed to cut down on temperature layering and keep conditions even from top to bottom.

High-Quality Industrial HVAC Air Turnover Units

Advantages of Air Turnover Systems

Air turnover units offer several built-in advantages that make them particularly effective for industrial and commercial spaces:

  • No Ductwork Required: Fully contained systems eliminate the need for roof penetrations or extensive duct runs
  • Quieter Operation: Low-speed fans reduce sound levels compared to rooftop units or traditional high-velocity systems
  • Temperature Uniformity: Maintains consistent temperatures across the space, typically within two degrees Fahrenheit
  • Air Destratification: Gently mixes warm and cool air throughout the facility to prevent temperature layering
  • Simplified Installation: Compact design saves space and does not require additional structural support

Applications of Air Turnover Units

Air turnover systems are ideal for large, open environments where traditional HVAC approaches often fall short. Their ability to deliver uniform air distribution, reduce energy costs, and simplify installation makes them especially effective in the following settings:

Warehousing and Distribution

  • Consistent heating and cooling across large volumes, including high-rack storage areas.
  • Helps maintain temperature variation within two degrees Fahrenheit throughout the space.
  • Lowers operational costs by using energy-efficient, low-speed fans.

Manufacturing & Assembly Facilities

  • Supports stable conditions for both personnel comfort and equipment reliability.
  • Effectively manages high internal heat loads and process-generated heat.
  • Improves overall airflow and air quality without complex ductwork.

Gymnasiums, Hangars, and Big-Box Retail

  • Tailored for high-ceiling spaces with fluctuating occupancy levels.
  • Enhances comfort and air quality control for both employees and visitors.
  • Reduces the need for additional ductwork or complex infrastructure.

Frequently Asked Questions

What is the difference between air turnover and traditional HVAC systems?

Air turnover systems use high-volume, low-speed fans to gently circulate conditioned air throughout a space with no ductwork required. On the other hand, traditional HVAC systems rely on forced air through ducts, which can lead to uneven temperatures in large, open areas. Air turnover keeps things consistent from floor to ceiling.

Absolutely. Air turnover units can be configured for heating, cooling, or year-round conditioning. Whether you’re dealing with Southern humidity or winter chills, they’re designed to maintain stable indoor conditions.

It depends on the size of your facility and whether it’s a new build or a retrofit. That said, these systems are often quicker to install than traditional ducted systems, especially since they’re self-contained and require minimal structural support.

Yes. One of the major advantages is their flexibility. Because they don’t rely on extensive ductwork or require heavy structural modifications, they’re a practical option for older facilities needing an HVAC upgrade.

Routine inspections and preventative maintenance go a long way. That includes checking fan and burner function, replacing filters, and calibrating controls. With regular service, these systems run efficiently for years with minimal downtime.

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.
