Dri-Eaz DriTec 4000i Desiccant Dehumidifier - dr4310

Dri-Eaz DriTec 4000i Desiccant Dehumidifier - dr4310

Say hello to the smartest, simplest, and best-performing compact desiccant dehumidifier on the market, the DriTec 4000i from Dri-Eaz. Its versatile design allows for flexible setup in low-clearance spots and in ducted applications.

Moisture Removal in Any Conditions

The 4000i uses desiccant drying technology to remove moisture even in low temperatures and low humidity conditions - making it an ideal solution for removing moisture from items like hardwood floors, concrete, walls, cabinets, plaster, brick and more. 

Since the DriTec 4000i doesn't collect water and doesn't use a temperature-sensitive refrigeration system, it will continue removing moisture effectively in sub-zero temperatures. It also dehumidifies reliably in low humidity conditions, even down to 0% relative humidity.

• Real-Time Temperature and Humidity Readings The digital display displays average pints-per-day removal along with real-time temperature and relative humidity percentage readings for inlet and outlet ducts. 
• Powerful Moisture Removal: It's rated to remove 118 pints of moisture per day in AHAM conditions (80 degrees F, 60% relative humidity). 
• Digital Hour Meter: An onboard hour meter measures cumulative operating time and stores it when the machine is unplugged to help you track total job hours and plan maintenance schedules.
• Portable and Compact: Large rubber wheels and a rugged folding handle make for easy maneuverability. This trusted Dri-Eaz dehumidifier stands at 33.13 H x 21.14 W x 20.25 D inches. 
• Onboard Humidistat: The adjustable humidistat allows you to set a desired relative humidity to maintain automatically.

This compact desiccant dehumidifier is extremely versatile, effective in a vertical or horizontal configuration, which is especially ideal for low-clearance areas such as crawl spaces and similar locations.

There are also 3 Dri-Tec 4000i ducting options: 

• Duct the Air Inlet: Duct the colder and/or drier air of the space into the air inlet to help improve desiccant performance.
• Duct the Process Outlet: Duct the process air outlet into hard-to-reach areas for distributed drying. You'll need to use layflat ducting for this configuration.
• Duct in Low-Clearance Areas: In a crawl space or another low-clearance area, you can operate the unit on its back. Duct the reactivation outlet outdoors and the duct the air inlet and process air outlet as you would in Options 1 and 2. You can also duct process air between floor joists for easier air distribution.

Additional Features

• Multi-Language Display: Displays readings in English, Spanish, French, or German.
• Efficiency-Boosting Technology: This unit uses a Positive Thermal Coefficient Heater for improved efficiency, safety, and a longer operating life.
• 3M Particle Filter: Captures harmful particles, resists microbial growth on the filter surface, and ensures maximum airflow throughout operation.
• Onboard Storage: A built-in compartment stores power cords and ducting components. Plus, the inside lid of the unit includes a quick guide for ducting setup.
• Long Power Cord: Easily set up shop thanks to its versatile design and 25-foot power cord.
