When it comes to controlling indoor humidity, especially in multi-family housing, hotels, and student housing, the IW25-5 by Innovative Dehumidifier Systems provides an efficient, space-saving solution. This compact unit, capable of removing up to 33 pints of moisture per day, offers flexible installation options with two configurations: In-Wall and On-Wall. Each option allows building owners and property managers to tailor dehumidification to their specific space needs while protecting against excess moisture, mold, and poor indoor air quality.

In-Wall Installation: Sleek, Low-Profile Dehumidification

The IW25-5 In-Wall model is designed to integrate directly into wall spaces, creating a streamlined, discreet look that minimizes visibility. With an Energy Star rating and a built-in automatic humidistat, the IW25-5 ensures continuous, efficient operation, activating only when humidity levels rise above a set threshold. This approach provides significant energy savings and protects walls, furnishings, and finishes from moisture-related damage.

For standard wall depths of 2×6 framing, the IW25-5 can be recessed to sit flush with the wall surface. In 2×4 wall cavities, however, the unit requires an exterior sleeve to accommodate the shallower depth, as it will extend slightly beyond the wall surface. This design flexibility makes the IW25-5 suitable not only for new constructions but also for retrofit applications, where in-wall installation may be desired but space might be limited.

On-Wall Installation: Adaptable and Accessible for Any Setting

When in-wall installation isn’t feasible—such as in concrete walls, spaces without wall cavities, or in certain retrofit applications—the On-Wall configuration becomes an ideal solution. Using a surface mount kit, the IW25-5 can be mounted on the wall’s exterior, providing all the benefits of effective humidity control without requiring a recessed cavity. This option is highly adaptable and allows for easy access to the unit for maintenance or repairs, making it a preferred choice in both new installations and retrofits.

Optional Accessories for Greater Flexibility

The IW25-5 offers a range of optional accessories that enhance its adaptability, ease of installation, and functionality. Two of the most impactful are the condensate pump and the exterior sleeve.

Condensate Pump

In situations where gravity drainage isn’t possible—such as in basements or below-grade installations—the condensate pump allows the unit to push collected moisture up to a higher drainage point. This accessory is essential in locations where the drainage point may be distant or positioned at a higher elevation than the unit itself. The pump seamlessly integrates with the IW25-5, ensuring reliable moisture removal and uninterrupted operation regardless of location constraints.

Exterior Sleeve

The exterior sleeve is an accessory specifically designed to support the IW25-5’s installation in 2×4 wall cavities. In these standard walls, where a flush installation isn’t possible, the sleeve provides stability and a finished look. While the unit will still extend slightly beyond the wall surface, the sleeve ensures a secure fit and professional appearance, making it a practical option for accommodating different wall depths.

A Flexible Solution for Any Space

With its versatile installation options, powerful moisture removal, and smart design, the IW25-5 is an ideal choice for property managers and owners aiming to control indoor humidity effectively. Whether installed in-wall or on-wall, this compact dehumidifier brings reliable protection against excess moisture and helps improve indoor air quality for occupants.

For those considering installation in 2×4 walls or below-grade settings, the exterior sleeve and condensate pump accessories provide the flexibility needed to ensure the IW25-5 works seamlessly in any environment. This makes the IW25-5 a truly adaptable, high-performance choice for humidity control across a wide range of applications.
