Series 100

Small Room Applications (100 SCFM)
Prevent Corrosion, Mold and Mildew. Compact, lightweight and rugged, the DH Series 100 desiccant dehumidifier is an ideal unit for small room applications.

Prevent Corrosion, Mold and Mildew
The DH-100 units produce dry air to prevent corrosion, increase readiness, reduce maintenance, and improve Mean Time Between Failure (MTBF) for electronic systems.With the DH-100 dehumidifiers, humidity can be controlled below levels at which moisture condenses
on surfaces, thereby preventing corrosion, mold and mildew formation.

The heart of the units is a state of the art, silica gel, desiccant dehumidification wheel. A self regulating, positive temperature coefficient (PTC) electric resistance heater is used for regeneration and low speed, low noise compact blowers are used to move supply and regeneration air throughout the unit. An adjustable humidistat provides relative humidity control and energy savings.

Principle of Operation
The operation of the DH-100 desiccant system is based on two counter current air streams flowing through a rotating desiccant wheel. Return air from the conditioned space is drawn through the rotating desiccant wheel. The desiccant adsorbs moisture from the air stream and the dry supply air is returned to the conditioned space. The moisture containing portion of the wheel rotates into the regeneration section. The desiccant releases the adsorbed moisture into the heated regeneration air stream which is then exhausted to the outside.

Series 500

Restoration & Remediation Applications (500 – 700 SCFM)
Portable desiccant dehumidifier for disaster recovery and water damage remediation. The Series 500 (DRY-700) is portable, self contained, and designed for maneuverability in small spaces like building elevators and tight corridors.

  • Rugged all aluminum cabinet construction
  • Advanced silica gel desiccant rotor
  • Single point power connection – 12′ self storing power cord
  • Solid state controls
  • Proportional controlled electric reactivation of desiccant rotor
  • Wheel mounted (skid mounted available for permanent installation)
  • Beaded air connections; accommodates
  • High External Static Pressure
  • Low maintenance-easy access to all internal components
  • Made in the USA
Desiccant Technology
Engineered to operate under severe operating conditions, the DRY-700 uses desiccant technology to remove water vapor directly from the air. Removing water from the air reduces the air vapor pressure, which improves evaporation. This makes the DRY-700 the logical choice for structural drying, support drying for mold remediation, and new construction building envelope drying.

Series 2900

Restoration & Remediation Applications (3000, 5000, 9000 CFM)
