Desiccant Dryers in the Philippines and Why You Need Them for Your Air Compressor

Introduction 

Moisture-free air is vital to avoid future problems for your compressed air system. This type of air, especially those with a dew point from -20 to -70° C, is also used for various manufacturing and commercial applications. Since it is impossible to directly harness dry air for industrial use from our immediate surroundings, you need a machine to help you get what you need.

Compresstech Resources takes great pride in offering top-quality desiccant dryers in the Philippines. With more than 34 years of experience in the industry, our team has built strong partnerships with various prominent figures and institutions. You can count on us to provide you and your company with tailored solutions that are innovative yet practical.

What Are Desiccant Dryers? 

Desiccant dryers are industrial equipment that uses a drying agent to eliminate water from the air channeled through the machine. It uses a desiccant—a unique adsorbent material that has a high affinity for water—to maintain an immediate dry environment by pulling and holding water molecules within itself.

The most common types of desiccants used for this type of dryer are:

Silica 

Also called silicon dioxide, silica is a chemical compound of two of the most abundant chemicals in the Earth’s crust: silicon and oxygen. This desiccant can hold 30% to 40% of its weight in moisture. Water molecules stick to their surfaces through adsorption, which is how it can help produce dry compressed air.

Activated Charcoal 

Manufacturers make this desiccant by heating ordinary charcoal in the presence of a gas. Aside from controlling moisture and humidity to prevent mold and mildew, activated charcoal can also remove unwanted smells. This fine, odorless, and black powder is an excellent adsorbent as it easily binds itself to molecules, ions, or atoms.

Aluminosilicate Minerals (Zeolites) 

Zeolites are aluminosilicate minerals that are natural compounds found in nature and are mined rather than synthesized. They have an open crystalline lattice, allowing molecules like water vapor to be held inside the crystal itself.

At Compresstech Resources, we offer a wide range of compressed air dryers in the Philippines. Reach out to us today for more information about our products.

How Do Desiccant Dryers Work? 

A desiccant dryer adsorbs water vapor into their specific drying agent’s large, dry surface area, which is usually a highly porous material. Adsorption happens as water vapor in the compressed air moves into the pores of the dry desiccant, and heat is released afterward. It is vital to note that water remains on the surface of the desiccant until it is stripped off.

Desiccant dryers pass the compressed air over a bed of desiccant material. When the bed capacity is at its limit, airflow is switched to the second bed of desiccant material while the first bed is generated. You can purchase timers or dew point monitoring equipment to control the regeneration phase.

What Are the Types of Desiccant Dryers?

There are two types of desiccant dryers: heated and heatless. Heated desiccant dryers use high temperatures to remove water vapor from the desiccant material not in use at that point in the cycle. These machines need large amounts of steam or electricity to operate.

On the other hand, heatless desiccant dryers can retain the heat of adsorption within the desiccant beads. This stored temperature is consumed during the regeneration process to remove moisture from the machine and ensure its quality.

Regardless of what type you need, Compresstech Resources can help you. We are a trusted source for high-quality desiccant dryers in the Philippines. You can be sure that we will listen to you throughout the process to find the best dryer for you.

What Size of Desiccant Dryer Do You Need? 

When deciding what size of desiccant dyer you should get, you must first understand how temperature and pressure affect water content in the air. Water vapor content will vary depending on the heat, since the more a temperature increases, so do the air’s ability to hold water. On the other hand, more moisture can be squeezed out from the air the more pressure there is.

Due to these complex relations, compressed air dryers have correction factors that can help determine what they can do in specific ambient conditions. It is recommended that you get a dryer that will be able to survive the hottest and most humid summer months to ensure that your machine won’t break down in the middle of production due to its inability to handle specific environmental factors.

If you still aren’t sure what you should get, worry not because Compresstech Resources has got you covered. We are a trusted desiccant dryer distributor in the Philippines and have a team of professionals who can assist you with any questions or concerns.

What Are a Few Tips You Should Follow When Installing Desiccant Dryers in the Philippines? 

Here are a few things to keep in mind when installing your unit:

Don’t Place It on the Floor 

One of the most common reasons why a desiccant dryer malfunctions is because of pathway blockages. Since it pulls air from its surroundings, dirt, dust, and other particles are often found in the different nooks and crannies of a unit. This is why you should place it in a location that’s free from any debris.

Give the Dryer Its Own Space 

Consider building or buying a shelf or stand for your air dryer to save yourself from possible repair costs. To allow cooler ambient air for heat dissipation, air dryers need to have extra space around them. This is why it’s recommended that you measure where you’ll place the machine before buying it to ensure that you won’t buy one too big.

How Long Do Desiccant Dryers Last? 

The lifespan of a desiccant dryer heavily depends on the conditions that the dehumidifying equipment is operated in. However, it is recommended that it is replaced once every three years for open-cycle systems and once every two years for closed-cycle systems.

Another indicator that shows that you need to have an expert look at your unit is the dew point temperatures it reaches. If it can’t get any lower than -40°C, it may be best to call a professional.

If you aren’t sure whether your machine needs a replacement or a repair, you can turn to Compresstech Resources.
