Santa Fe Impact155 Large Room Dehumidifier - sa8108

Santa Fe Impact155 Large Room Dehumidifier - sa8108  

The Santa Fe Impact155 dehumidifier is the perfect solution for removing excess moisture from large basements and crawl spaces. At AHAM rating conditions (80°F at 60% humidity), the large-capacity unit removes up to 155 pints of moisture per day and covers up to 4,000 square feet.

At complete saturation (100% relative humidity), the dehumidifier’s capacity doubles to an impressive 310 pints per day. 

Easy Humidity Control

For easy humidity control, the unit features 3 humidity settings – dry, normal, and humid – to help you choose the best level for your space. Simply move the humidity control knob to your desired setting. The dehumidifier will run intermittently to maintain the set humidity level.

Designed To Fit Your Needs

This crawl space and basement dehumidifier features a horizontal design that helps it fit easily into narrow and tight spaces. Place the unit in a finished basement, an unfinished basement, or on open ground in your crawl space. Because of its shorter footprint, the dehumidifier can be installed wherever it is convenient.

How It Works

The Santa Fe Impact155 dehumidifier uses a CFC-free refrigerant to draw in a stream of warm, humid air at the front of the unit and pass it through 1 of 2 evaporator coils. At this coil, the air temperature is cooled to below its dew point, condensing moisture in the process and dripping the water into the unit’s reservoir or, if equipped, a hose for draining.

Following this process, the now cooled and dried air passes through a second coil where it is reheated and blown out into the room or crawl space. This Santa Fe dehumidifier performs dual-air distribution by blowing the reheated air out into the surrounding space from each side of the unit, which results in quicker and more efficient dehumidification and a well-balanced humidity level.

Setting Up A Drain Trap

Santa Fe recommends setting up a drain trap when installing any of its horizontal dehumidifiers, including this model (formerly known as the Max Dry Dual XT). This prevents air from moving back up through the hose and backflowing water into the machine.

This also prevents potential water leaks from the corners of each unit. It's easy to create a drain trap using the included drain hose or a separate PVC trap. Watch this video on how to create a drain trap for your Santa Fe dehumidifier to learn more.

Condensate Pump Option

If the gravity drain option is not aligned with your drainage needs, a condensate pump is also available. This kit will give you the option of running the drain hose upward and out through a window or around a doorway to your yard or garden. The condensate pump is energy-efficient and works with a float switch that directs the pump to run only when necessary.

Ducting Options

There are several options for ducting this Santa Fe dehumidifier for operation in a number of spaces at once. This also allows you to hide the unit in a storage space. Inlet (12-inch. ducting) and outlet (10-inch ducting) duct accessory kits are available to suit your needs. Setup configurations include:

• Operating the unit without ducting to dehumidify in an open space.
• Ducting multiple rooms to allow air to flow simultaneously.
• Ducting one room and directing the unit to discharge air into another room.
• Running ductwork to the far ends of a crawl space to force air circulation.
• You can add the ducting kit if you're looking to duct your model. 

Features

•  Dual-Air Distribution: This patent-pending capability enables the unit to blow dehumidified air out from vents located on both sides of the unit, which results in more balanced humidity and air circulation.
•  Horizontal Design: The Impact155 has a horizontal design that's ideal for compact crawl spaces and basement applications. 
•  Reliable Heavy-Duty Moisture Removal: Made in Madison, WI, this dehumidifier is backed with a 6-year warranty and designed for years of use in tough environments. 
•  Money-Saving Design: Remove up to 7.3 pints of moisture per kWh. This powerhouse dehumidifier offers a 3.4 L/kWh Energy Factor. 

Additional Features

•  Fan Control: A fan control switch allows for continuous fan operation or operation only when the unit is actively removing moisture from the air.
•  MERV 13 Air Filter: A pleated MERV 13 air filter cleans the air as it enters the unit. This filter captures particles as small as 1 micron in size and helps the dehumidifier works more efficiently. To replace MERV 13 filters, you can find them here. For slightly less efficient air filtration, you can add the MERV 11 filter. 
•  Gravity Drainage: Simply attach the included 8-foot drain hose to the unit and route to a drain.
•  Wide Temperature Range: This crawl space dehumidifier operates efficiently in temperatures down to 49 degrees F and up to 95 degrees F.
•  Auto Restart: It automatically starts back at your previous settings after a power outage.
