Williams Air Sponge Dehumidifier (DH 130A)

The Williams Air Sponge Whole House Dehumidifier, also known as the Williams Air Dehumidifier DH-130A, is a great solution for eliminating excess moisture from your entire home. This energy-efficient dehumidifier extracts 130 pints of water per day under AHAM conditions (80 degrees Fahrenheit, 60% relative humidity) and 260 pints per day at saturation. It is one of few ducted dehumidifiers that can cover virtually any size home and operate in temperatures as low as 40 degrees Fahrenheit.

Excess humidity can pose many threats to your home and your health. In addition to causing uncomfortable stuffiness and musty smells, untreated humidity can also promote growth of mold and mildew, which can aggravate allergy and asthma conditions and lead to structural damage. With the Williams DH-130A high-capacity dehumidifier, you‘ll maintain a comfortable humidity level and reduce potential harm to your home and health.

The Williams Air Sponge Dehumidifier is furnished with a variety of features that make installation, operation, and maintenance a breeze. Key highlights include:

• Automatic Defrost: An automatic defrost function turns off the compressor when frost begins to build up on the interior coils and runs the fan until ice melts, preventing damage to the dehumidifier.
• Washable Filter: Nylon mesh material makes the permanent air filter durable and reusable even after frequent cleaning.
• Quiet Operation: High-density lining made of 1-inch-thick insulated material conceals sound, releasing minimal noise during the dehumidifier’s operation.
• Overflow Protection: An internal float switch disables the dehumidifier’s compressor and stops water production if drain lines are clogged or restricted, keeping water from overflowing.
• Safety Shut-Down: A built-in shut-off switch automatically turns the power off when the door is opened.
• Secondary Drain Line: A secondary drain line connection releases water to a visible area, signaling problems with the primary drainage system. Both condensate drains must be trapped external to the dehumidifier and connected according to national and local plumbing codes.
• Optional Wall-Mounted Control: An optional remote dehumidistat—resembling a thermostat—can be mounted in your home for easy access.

Whole-Home Dehumidification

The Williams Air Sponge Whole House Dehumidifier effectively lowers the humidity in your entire house. First, moist air is drawn into the dehumidifier through the inlet duct. Once air passes through the air filter, airborne contaminants are removed. Next, the air moves through the dehumidifier to the cold evaporator coils. Moisture is then condensed, collected in a stainless steel drain pan, and carried away through a drain hose. After the dehumidification process is complete, clean, moisture-free air is released back into your space, constantly providing a comfortable breathing environment for your home.

Maintains Optimum Humidity Level

This home dehumidifier consistently monitors the air in each space of your home and automatically adjusts the humidity until it reaches your ideal level. Every hour, the DH-130A’s fan runs for 15 minutes and draws in a sampling of air to evaluate and assess the humidity level. A built-in dehumidistat senses when the relative humidity exceeds the preset level. If excess moisture is detected in the air, the humidity sensor signals the compressor to activate. The fan and compressor will continue to operate until the air returns to your desired humidity level.

Two Installation Methods

The Williams Air Sponge Whole House Dehumidifier can run as a standalone appliance, covering a space of up to 3,000 square feet, or it can be connected to your current central heating and air conditioning system using insulated ducts to provide unlimited square foot coverage. To install the Williams dehumidifier to an existing HVAC system, connect insulated flexible ducts from the DH-130A’s inlet collar to the return ducts on your air conditioner and the outlet collar to your AC outlet.

For easier setup and immediate use, the whole house dehumidifier can be placed on a flat surface in basements, attics, or crawl spaces to run as a standalone dehumidifier. To set up this configuration, you must have an electrician hardwire the unit into your electrical system and run a drain line. Rubber mounting feet allow you to properly level the dehumidifier without scratching the bottom or causing unnecessary vibration. You can also suspend the DH-130A dehumidifier above ceilings using an optional hanger kit (sold separately), which includes four brackets and four rubber isolators.
