High-Performance Heating Systems for Industrial & Commercial Applications

Heating systems do more than keep spaces warm — in many industrial and commercial facilities, they protect equipment, maintain production quality, and ensure occupant safety. Lincoln Associates delivers engineered heating solutions designed for reliability, efficiency, and performance in demanding environments.

From large manufacturing plants to warehouses, laboratories, and public facilities, we provide systems that meet your operational needs, energy goals, and budget.

Applications include:

  • Industrial Manufacturing: Maintaining process temperatures and worker comfort in large facilities.

  • Warehousing & Distribution: Even heating for high-bay spaces and dock areas.

  • Food & Beverage: Temperature stability for processing and storage areas.

  • Commercial Buildings: Reliable, efficient heating for offices, schools, and retail spaces.

  • Mission Critical Facilities: Consistent temperature control for sensitive equipment.

  • Agricultural & Horticultural Operations: Protecting crops and livestock in cold weather.

How Commercial & Industrial Heating Works

Commercial and industrial heating systems use a range of technologies to deliver heat safely and efficiently. The right system depends on your facility’s layout, load profile, and available energy sources.

Common Heating Technologies Include:

  • Gas-Fired Unit Heaters: Direct, reliable heat for large open spaces.
  • Infrared & Radiant Heaters: Targeted heating for work zones, reducing wasted energy.
  • Make-Up Air Units with Heating: Introducing fresh air while maintaining comfortable temperatures.
  • Hydronic Heating Systems: Using hot water or steam to heat spaces via coils or radiators.
  • Electric Heating Systems: Flexible and easy to install where gas is unavailable.

Matching the System to the Application

Choosing the right heating system involves balancing performance, efficiency, and lifecycle cost. Lincoln Associates partners with leading manufacturers to ensure every system is built for the exact needs of your facility.

Factors We Evaluate:

  • Space Size & Layout: Selecting the most effective heat distribution method.
  • Fuel Source Availability: Natural gas, propane, electricity, or steam.
  • Air Quality Requirements: Ensuring heating works in concert with ventilation and filtration.
  • Energy Efficiency Goals: High-efficiency units, variable speed fans, and condensing technology.
  • Environmental Conditions: Designing for extreme temperatures or high-moisture areas.
  • Integration: Seamless operation with existing HVAC systems.

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.
