Professional Dehumidifiers for Water Damage & Moisture Control

When excess moisture enters a building, removing standing water is only part of the restoration process. Moisture can remain in the air, flooring, walls, subflooring, contents and other structural materials. Professional dehumidifiers help control the humidity of the drying environment so that moisture can continue moving out of affected materials.

UnoClean offers a broad selection of commercial, industrial and restoration dehumidifiers for applications ranging from water damage restoration and structural drying to warehouse humidity control, crawlspaces, commercial buildings and specialized industrial environments.

The current selection includes Ebac commercial and industrial dehumidifiers in a wide range of capacities, along with compact equipment and other dehumidification options. The category also includes smaller Eva-Dry units for applications where a compact renewable dehumidifier is appropriate.

Choose the Right Type of Dehumidifier

Not every moisture-control job requires the same type of equipment. The best dehumidifier depends on the size of the affected area, moisture load, drying objective, temperature, available electrical service and how the equipment will be installed.

Dehumidifiers for Water Damage Restoration

Water damage restoration requires rapid control of moisture throughout the affected structure. After standing water has been extracted, the remaining moisture can continue to migrate into the surrounding air. If the air becomes saturated, evaporation from wet materials slows.

A professional restoration dehumidifier removes water vapor from the air and helps maintain a drying environment in which moisture can continue evaporating from wet materials.

Restoration dehumidifiers are designed around the practical requirements of the jobsite. Depending on the model, features can include portable construction, condensate collection or pumping, humidity controls and electrical configurations intended for professional use.

LGR Dehumidifiers for Structural Drying

LGR stands for Low Grain Refrigerant. LGR dehumidifiers are a specialized type of refrigerant dehumidifier designed to continue extracting moisture as the air becomes drier.

This characteristic makes LGR equipment particularly useful during the later stages of professional structural drying. As moisture is removed from a building, the relative humidity of the drying environment decreases. An LGR unit is designed to continue operating effectively under these progressively drier conditions.

UnoClean's Dri-Eaz documentation describes its LGR equipment as intended for water damage restoration, structural drying, construction and rental applications. The Dri-Eaz LGR 3500i, for example, is listed at 170 pints per day at AHAM conditions, while the LGR 2800i is listed at 130 pints per day at AHAM conditions.

How a Refrigerant Dehumidifier Works

Refrigerant dehumidifiers remove moisture by passing humid air across a cooled surface. Water vapor condenses into liquid water, which is then collected and drained from the machine. The dehumidified air is returned to the environment.

As the surrounding air becomes drier, conventional refrigerant equipment can become less effective because there is less moisture available for condensation. LGR equipment uses additional cooling stages to improve moisture removal as the drying environment reaches lower humidity levels.

Commercial & Industrial Dehumidifiers

Not every dehumidification application involves a water-loss emergency. Commercial and industrial facilities may require ongoing humidity control to manage moisture in warehouses, storage areas, production environments, crawlspaces and other spaces.

UnoClean's current Ebac selection illustrates the range available for these applications. Current listings include units from 24-pint compact systems through 285-pint industrial equipment, with some industrial desiccant models listed at 364 and 562 pints per day.

High-Capacity Dehumidifiers

Large commercial and industrial environments can introduce substantial moisture loads. In these applications, equipment capacity becomes a critical consideration.

UnoClean's current Ebac selection includes high-capacity models such as the PD220-D at 190 pints per day, CD425-D models at 285 pints per day, DD700 models at 231 pints per day and DD1200 models at 562 pints per day. The DD700 and DD1200 are industrial desiccant models, while the PD and CD series include commercial and industrial refrigerant equipment.

High-capacity equipment should be selected based on the actual moisture load and environmental requirements rather than simply choosing the machine with the largest published capacity.

Desiccant Dehumidifiers

Desiccant dehumidifiers use a different moisture-removal method from refrigerant systems. Instead of relying primarily on condensation over a cold coil, desiccant equipment uses a moisture-adsorbing material to remove water vapor from the air.

This makes desiccant technology useful for specialized applications where very low humidity or specific drying conditions are required. Industrial desiccant systems can also be appropriate when environmental conditions make conventional refrigerant dehumidification less suitable.

UnoClean currently lists Ebac DD700 and DD900/DD1200 industrial desiccant dehumidifiers, including different electrical configurations.

Portable Dehumidifiers

Portable dehumidifiers provide flexibility for contractors, restoration professionals and facilities that need to move equipment between rooms or job locations.

Portability becomes particularly valuable in restoration because drying conditions can vary from one job to another. A portable unit can be transported to the affected structure and positioned where dehumidification is needed.

UnoClean's current category includes portable professional Ebac models as well as compact units. The lineup includes Ebac RM40, RM40P, CD30-S and other portable or compact equipment.

Dehumidifiers With Condensate Pumps

Condensation removed from the air has to go somewhere. Depending on the installation, collected water may be drained through a hose or pumped to a remote drain location.

Models with integrated or high-lift condensate pumps can provide additional installation flexibility when gravity drainage is unavailable or when the drain point is located above the dehumidifier.

UnoClean's current selection includes the Ebac RM40P with a high-lift condensate pump and CD425-D configurations with pumps. The category also includes the Ebac AD850E with condensate pump.

Wall-Mounted Dehumidifiers

Wall-mounted equipment can be useful when floor space is limited or when the installation calls for the dehumidifier to remain in a dedicated position.

UnoClean currently offers Ebac wall-mounted models including the WM80-D and WM150-D. The WM80-D is listed at 62 pints per day, while the WM150-D is listed at 71 pints per day.

Wall-mounted equipment should be installed according to the manufacturer's requirements, including appropriate mounting support, electrical service and condensate drainage.

Dehumidifiers for Crawlspaces & Enclosed Areas

Crawlspaces and other enclosed areas can have persistent moisture problems because of limited airflow, ground moisture, plumbing conditions and temperature differences.

A properly selected dehumidifier can help manage humidity in these environments. Compact commercial units are often easier to position in restricted spaces, while installation requirements such as drainage and electrical access still need to be considered.

When choosing equipment for a crawlspace, consider the available clearance, moisture load, temperature, drainage method and whether the equipment will remain permanently installed.

Dehumidifiers for Commercial Buildings & Warehouses

Warehouses and commercial buildings may require dehumidification when humidity is affecting stored materials, equipment, building conditions or operating processes.

The appropriate system depends on the size of the space and the amount of moisture entering it. Larger facilities may require substantially more capacity than a portable restoration unit can provide, while smaller areas may be adequately served by compact commercial equipment.

For ongoing humidity control, a humidistat can also be useful because it allows compatible equipment to respond to changing humidity conditions rather than requiring continuous manual operation.

Dehumidifiers for Construction & Renovation

Construction and renovation projects can introduce significant moisture through concrete, drywall, plaster, coatings and other building materials. Controlled dehumidification can help manage humidity while materials dry.

Portable professional dehumidifiers are particularly useful on jobsites because equipment can be repositioned as work progresses. LGR dehumidifiers are also used in construction and drying applications where higher-performance moisture removal is required. Dri-Eaz documentation hosted by UnoClean specifically identifies its LGR equipment for construction as well as water damage restoration and rental applications.

How Dehumidifiers Work With Air Movers

Dehumidifiers and air movers perform different but complementary jobs during structural drying.

Using both types of equipment together creates a drying system in which air movement promotes evaporation and dehumidification removes the moisture that enters the air. UnoClean's restoration equipment category includes both air movers and dehumidifiers for this reason.

How to Choose the Right Restoration Dehumidifier

Dehumidifier selection should be based on the drying application rather than simply the physical size of the room.

• Assess the water loss: Determine how much water entered the structure and whether materials are still actively releasing moisture.
• Identify affected materials: Wood, drywall, flooring, insulation and contents can retain moisture differently.
• Determine the affected area: Consider the volume of the drying environment rather than relying only on square footage.
• Consider temperature: Dehumidifier performance can vary with operating temperature.
• Choose the appropriate technology: Refrigerant, LGR and desiccant systems serve different drying requirements.
• Check electrical requirements: Verify voltage, amperage and phase requirements before bringing equipment to the jobsite.
• Consider drainage: Determine whether gravity drainage or a condensate pump is appropriate.
• Consider portability: Restoration contractors may need equipment that can be transported between jobs.
• Use monitoring: Moisture meters and environmental measurements should be used to evaluate drying progress.

Dehumidifier Capacity: What Does Pints Per Day Mean?

Dehumidifier capacity is commonly expressed in pints of water removed per day. However, the published capacity should always be considered alongside the conditions under which the rating was measured.

Temperature and relative humidity have a significant effect on how much water a dehumidifier can remove. A machine that removes a certain amount of water under one set of test conditions may remove a different amount under different jobsite conditions.

For this reason, compare equipment using the manufacturer's published rating conditions rather than treating the pints-per-day number as an absolute amount that will occur in every environment.

Professional Dehumidifier Applications

Popular Ebac Dehumidifier Capacity Ranges

Ebac represents a substantial portion of the current UnoClean dehumidifier selection. The available models span a broad range of capacities and configurations, making the brand relevant to both professional restoration and larger commercial or industrial applications.

The capacities above are the current listed product values shown on UnoClean's category pages and are provided for general comparison. Actual moisture removal depends on operating conditions and the manufacturer's specified rating conditions.

Commercial vs. Restoration Dehumidifiers

Commercial and restoration dehumidifiers can overlap in capacity, but the application requirements are often different.

Using Humidistats With Dehumidifiers

A humidistat can provide humidity-based control for a compatible dehumidifier. Rather than requiring the machine to run continuously, the control can respond to humidity conditions and operate the equipment according to the selected setting.

This can be particularly useful for ongoing commercial humidity control. For example, a facility may need to maintain a controlled humidity range without operating the dehumidifier continuously when conditions are already within the desired range.

UnoClean also carries Ebac humidistats and related dehumidifier accessories. Compatibility varies by equipment model, so the humidistat should always be matched to the specific dehumidifier.
