Desiccant Dehumidifiers and Large Desiccant Dehumidifier Applications

Get Quote

Sunbelt Rentals Pump & Power Services locations offer large capacity desiccant dehumidifiers ideal for water damage restoration applications, condensate and humidity control in manufacturing, and corrosion and humidity control for industrial coating and lining applications, as well as moisture mitigation in construction projects. By utilizing advanced desiccant technology to provide a low dew-point airstream and absorbing moisture vapor in the air, Sunbelt’s desiccant dehumidifiers lower moisture levels in both the ambient indoor air and moisture content in building materials. This reduces the premature degradation of building materials and lowers the risk of microbial growth due to high moisture levels within a structure. Desiccant dehumidifiers are the most efficient option for humidity control, are suitable for use in nearly all environmental conditions, and can be operated as a stand-alone strategy or as a component of a more complex environmental control system with other air treatment components such as air conditioners, heaters and HEPA filtration units.

Large Desiccant Dehumidifier Applications

  • Water Damage Restoration — Provide a low-dew point air stream to quickly pull moisture from building materials that have come in contact with water due to storms, floods, fires, and piping failures. Quickly dry out wet buildings and structures to prevent growth of mold and fungus.
  • New Construction Dehumidification — Speed drying and curing of construction materials; also helps prevent odors and mold contamination.
  • Humidity Control in Buildings — Use alone or with other air-treatment components, such as air conditioners, heaters and HEPA filters.
  • Industrial Preparation and Surface Coatings — Prevent condensation inside tanks prior to painting or industrial coating to ensure proper bonding.
  • Industrial Condensation Prevention — Eliminate condensation in industrial and manufacturing processes to ensure high quality.
  • Power Plant & Marine Lay-up — Prevent corrosion in utility and industrial piping idled for long periods by lowering the ambient dew point.

Note: Ducting is available in 25' lengths.

LARGE DESICCANT DEHUMIDIFIERS utilize a solid desiccant rotor that is slowly rotated by a drive motor. As the rotor turns, this produces very dry discharge air with extremely low relative humidity, which is ducted to the area being treated to facilitate drying or other moisture control applications. Many advanced features are included to provide precision control and maximum operating efficiency. Electric, gas and propane reactivation types are available. All models require electric power to energize the controllers and blower motors.

  • 600 cfm models come in two options. Single phase 230 Volt comes in a portable unit that will run off a spider box and is ideal for residential or construction applications. 460 Volt / 3 Phase unit comes mounted in a lifting cage with fork pockets and is built for industrial projects.
  • 1000/2000 cfm combination unit is 460 Volt / 3 Phase and has an option for either 1,000 or 2,000 cfm. This allows you to run the unit at a lower setting, decreasing energy use and cost. Unit is mounted in a lifting cage with fork pockets and casters.
  • 5,000 cfm Tri-Fuel models can utilize electric, natural gas or propane gas for the reactivation energy, allowing you to choose the most efficient energy method. Unit electrical operation is 460 Volt / 3 Phase with single point hookup for either natural gas or propane. Unit comes in a lifting cage with fork-pockets and is less than 48” wide allowing for units to be shipped side-by-side.
  • 15,000 cfm Tri-Fuel units utilize the same technologies found in our 5,000 cfm units. Ideal for outside use, the units are mounted on a galvanized steel skid, surrounded by a lifting cage. Units require 460 Volt / 3 Phase and can utilize natural gas or propane.

HYBRID COOLING UNITS are designed to provide practical moisture control in hot and humid environments. The Sunbelt HCU units bring makeup air into a space by using a cooling coil to control temperature while a desiccant rotor wheel controls ambient humidity. The Sunbelt HCU units are very energy efficient, reducing the overall cost of operation by lowering the amount of power and fuel necessary for operation. The HCU design combines practical cooling and desiccant dehumidification technologies into one energy efficient package. The Sunbelt HCU units are often utilized in construction drying projects, protective coating application projects, and in seasonal applications within the power generation, manufacturing and entertainment industries.

  • 4,000-6,000 CFM
  • Humidity or temperature demand control
  • High energy efficiency
  • Variable frequency drive for capacity control
  • Digital control with optional remote monitoring
  • Optimizes refrigeration-based A/C and desiccant-based dehumidification performance

SUNBELT AIR MONITORING SYSTEMS (SAMS) offers a wireless solution for monitoring job site conditions. Originally designed to meet stringent military specifications for tank lining, SAMS successfully monitors the conditions of nearly any critical dehumidification project and is the only logging system able to continuously collect conditions in the event power and/or internet connectivity is lost.

  • Perfect for use on industrial coating and painting projects and construction sites.
  • Invaluable project documentation of job site conditions.
  • Optional sensors available to measure air pressure differential, CO2 and other gases, and porous materials such as wood, concrete and plaster.
