How Do Desiccant Dehumidifiers in San Francisco Work?

Dealing with moisture damage in your home? You’ve probably stumbled on the words “desiccant dehumidifier” during your search for the perfect solution.

You may have also come across advertorials about overpriced desiccant dehumidifiers that are more fluff than function. But if you find the right system for your needs, there’s no better way to reduce the humidity levels in your home.

Desiccant dehumidifiers are a more efficient and quieter alternative to the traditional compressor dehumidifiers that have become a staple in homes and businesses around San Francisco. Desiccant dehumidifiers use water-absorbent chemicals in a process that can reduce moisture levels far lower than that clunky compressor your granddad used back in the day.

But how do they work? Read on to find out:

The Technology

Inside a desiccant dehumidifier, you’ll find three important components. First, there’s the desiccant wheel, which contains a water-absorbent chemical called the “desiccant.”

Second, you have a heater. And finally, you have a series of fans used to inhale and exhale the air inside your home.

How Desiccant Dehumidifiers Work

A compressor dehumidifier uses evaporator coils – typically cooled with refrigerant – to reduce the temperature of incoming air. This causes the air to condense so it can be expelled into a water tank or via a drainage pipe. Though effective, this system has one major drawback; the air outside the device needs to be warmer than the evaporator coils in order for the unit to work.

When temps dip, so does the compressor’s performance, warns Andatech. Instead of using evaporator coils, a desiccant dehumidifier draws in the air and passes it through the desiccant wheel.

The chemicals on the wheel absorb the water. The heater then warms the chemical to regenerate it, creating an efficient cyclical process of dehumidification.

The absorbed water is then flushed from the system via a pipe or into a water tank, much like a compressor unit. Desiccant dehumidifiers keep working even under the coldest conditions, so they’re effective for any room in your home, from your basement to the attic.
