Archives and preservation environments protect materials that carry historical, legal, and cultural value. Museums, libraries, government records facilities, universities, and corporate archives all rely on controlled storage conditions to maintain document integrity over time.

Humidity plays a defining role in preservation. Fluctuations can lead to paper degradation, warping, mold growth, and long-term deterioration of sensitive materials. Lincoln Associates provides precision solutions that integrate with industrial/commercial humidification systems to support stable, controlled environments for long-term preservation.

Why Humidity Control Is Critical for Archives

Archival environments are designed to preserve materials for decades or centuries, which places strict demands on environmental stability. Humidity influences how materials age, respond to storage conditions, and resist biological threats. Even small fluctuations can create cumulative damage over time.

Several preservation risks are tied directly to humidity levels, especially in archives that store paper, photographs, film, textiles, and other organic materials.

  • Preservation of Paper and Organic Materials: Paper, parchment, photographs, and textiles respond quickly to environmental changes. Low humidity can cause brittleness and cracking, while elevated moisture levels accelerate chemical breakdown and decay.
  • Prevention of Mold and Biological Growth: Excess humidity creates conditions that support mold, mildew, and microbial activity. Controlled environments reduce the risk of biological damage to irreplaceable materials.
  • Dimensional Stability: Humidity fluctuations cause expansion and contraction in organic materials. This movement leads to curling, warping, and structural damage that cannot be reversed.
  • Preservation Standards and Best Practices: Archival institutions follow strict environmental guidelines to protect collections. Maintaining relative humidity between 40 and 55 percent supports conservation goals and reduces long-term risk.

Archival Environments That Depend on Humidity Control

Archives are not limited to one type of facility. Any environment responsible for preserving sensitive physical materials needs stable humidity control to reduce deterioration, protect collection value, and support long-term access.

Museums and Cultural Institutions

Artifacts, manuscripts, and historical documents require stable humidity to prevent deterioration. Controlled environments protect materials that cannot be replaced.

Libraries and Special Collections

Rare books and archival collections depend on stable storage conditions to protect bindings, paper fibers, and inks from degradation.

Government and Institutional Records Storage

Large volumes of records must remain intact for legal and administrative use. Environmental consistency supports long-term accessibility.

Film, Photography, and Media Archives

Film negatives, prints, and magnetic media are highly sensitive to moisture. Stable humidity extends usable lifespan and preserves image quality.

Benefits of Proper Archive Humidification

  • Protection of historical documents and artifacts
  • Reduced risk of mold and biological contamination
  • Prevention of warping, cracking, and material degradation
  • Stable conditions for long-term preservation
  • Consistent environmental performance across storage areas
  • Support for professional conservation standards

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.
