Advanced Indoor Air Quality Solutions for Commercial & Industrial Facilities

Indoor Air Quality (IAQ) impacts more than comfort—it directly affects occupant health, regulatory compliance, product integrity, and operational performance. In commercial and industrial environments, airborne contaminants, humidity imbalances, and ventilation issues can lead to safety risks, product defects, and increased energy costs.

Lincoln Associates delivers engineered IAQ solutions designed to control particulates, pathogens, odors, and humidity levels in a wide range of demanding applications.

Common environments benefiting from IAQ optimization include:

  • Healthcare & Laboratories: Infection control, cleanroom compliance, and precision climate conditions.

  • Food & Beverage Processing: Contaminant control for sanitation compliance and product safety.

  • Pharmaceutical Manufacturing: GMP standards for air cleanliness and moisture control.

  • Education & Public Buildings: Healthy environments to reduce absenteeism and improve productivity.

  • Industrial Facilities: Dust, fume, and particulate management for worker safety and equipment longevity.

  • Museums, Archives & Art Storage: Stable air quality to preserve sensitive materials.

  • Data Centers & Electronics: Preventing electrostatic discharge and corrosion.

How IAQ Systems Work

Effective IAQ management uses a combination of ventilation, filtration, purification, and humidity control strategies. Each element works together to remove airborne contaminants and maintain stable air quality parameters.

Core Components of IAQ Solutions:

  • High-Efficiency Filtration: MERV-rated filters and HEPA options capture fine particles, dust, and allergens.
  • Air Purification: Ultraviolet germicidal irradiation (UVGI), bipolar ionization, and photocatalytic oxidation neutralize bacteria, viruses, and VOCs.
  • Humidity Control: Proper humidification or dehumidification to prevent mold growth, material damage, and static discharge.
  • Ventilation Systems: Controlled introduction of outdoor air to dilute indoor pollutants.
  • Airflow Management: Ensuring proper distribution to prevent stagnant zones and hot/cold spots.

Matching the System to the Application

No two facilities have the same IAQ challenges. Lincoln Associates partners with leading manufacturers to offer a range of solutions tailored to your environmental requirements, regulatory standards, and building design.

Types of IAQ Solutions We Provide:

  • Filtration Upgrades: Retrofitting existing HVAC systems for higher MERV or HEPA performance.
  • Air Purification Systems: In-duct or standalone solutions for microbial and odor control.
  • Humidity Control Systems: Integrated humidifiers and dehumidifiers for precise moisture management.
  • Energy Recovery Ventilation (ERV): Balancing fresh air intake with energy efficiency.
  • Custom Air Handling Units: Built to integrate multiple IAQ functions in one system.

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.
