Replacement Steam Coils for HVAC Systems

Steam coils play a crucial role in industrial and commercial HVAC systems that rely on steam heat exchange. These heating coils transfer thermal energy from pressurized steam to air streams within air handlers, makeup air units, and other heating systems.

At Lincoln Associates, we supply high-performance steam coil replacements engineered to meet the demands of institutional, industrial, and commercial environments. Our coil experts work closely with contractors and engineers to ensure fast, reliable solutions that restore heating capacity and system uptime.

What are Steam Coils and Why Do They Matter?

Steam coils operate by circulating steam through a network of tubes within a coil assembly. As steam condenses inside the coil, it transfers heat to the surrounding air, making these coils essential to space heating and process temperature control.

Over time, steam coil performance can deteriorate due to internal fouling, condensate hammer, tube erosion, or freeze damage. This degradation reduces heating effectiveness, increases energy consumption, and places strain on HVAC equipment. Replacing damaged or underperforming coils ensures consistent heating output and prevents avoidable system failures.

Applications of Steam Coils

Steam heating coils are used in a wide range of HVAC applications, including:

  • Commercial air handling units and makeup air systems
  • Industrial process air heating and drying systems
  • Institutional buildings requiring controlled indoor temperatures

Lincoln Associates provides steam coils compatible with OEM system configurations and capable of meeting custom dimensional requirements. These heating coils are essential in applications where reliable steam heat exchange is critical for comfort, safety, or operational efficiency.

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.
