Additional Information

Description

DCA vertical dehumidifiers provide commercial and industrial moisture control where a vertical equipment configuration better suits the available mechanical space or installation requirements.

Eight available models support different airflow and humidity-control needs. These indoor-rated units can be configured for pool rooms, commercial buildings, replacement installations, and specialized applications.

Manufactured in the United States, DCA systems incorporate serviceable components and practical equipment designs that support long-term operation.

Space-Efficient Configuration

Vertical cabinet construction accommodates indoor installations where equipment footprint and duct arrangement are important.

Multiple Capacities

Eight models provide 1.5–8 ton capacities and 650–3,600 CFM airflow.

Standard Reheat Condenser

Returns heat to the discharge air to support conditioned-air delivery.

Multiple Heat-Rejection Options

Remote air-cooled, pool water heating, and water-cooled configurations are available.

Supplemental Heating

Electric duct heaters, gas duct furnaces, and external hot water coils support application-specific heating needs.

Flexible Air-Side Options

Multiple supply arrangements, fresh-air openings, and filtration options support integration with existing systems.

DCA vertical systems combine controlled moisture removal with a practical, space-efficient design.

Their configurable heat-rejection and heating options help facilities maintain stable indoor conditions while addressing installation limitations. Non-proprietary controls and serviceable components simplify long-term maintenance planning.

For applications requiring larger capacities or outdoor installation, DCA also offers horizontal dehumidifiers within Lincoln’s broader industrial dehumidification solutions.

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.
