Learn more below to know what you don’t know about honeycomb dehumidifiers.

What is a Honeycomb dehumidifier?

Generally, Honeycomb Dehumidifier is the equipment you can use to eliminate moisture from various plastic materials.

Honeycomb dehumidifier works with humidity control. It has high adsorption ability, energy-saving, and fast-absorbing speed.

Honeycomb Dehumidifier

Honeycomb dehumidifier provides you an option to add a heater or temperature-controlling device to perform the dual functioning of dehumidifying and drying simultaneously.

It can effectively reduce the material’s moisture content and shorten the product drying cycle. This will help you achieve high-quality end products through injection molding or plastic extrusion processes.

The honeycomb is composed of several cells deformed like a three-dimensional hexagonal honeycomb. It is widely applied to dehumidify and dry in pharmaceuticals, foodstuffs, electronic materials, and other industries.

How does cool dual structure help you achieve lower dew point in honeycomb dehumidifier?

A dual cool structure and honeycomb desiccant can help you achieve a lower air dew point in the Honeycomb dehumidifier. Double cool structure, better efficiency, excellent performance, and convenience are only three of the many benefits you get from Honeycomb Dehumidifier.

When the relative humidity of air reaches 100%, that is known as a dew point. When the air has a temperature level on or below the dew point, it loses its ability to absorb more moisture, ultimately resulting in the condensation process. Honeycomb dehumidifier helps you achieve a lower dew point of – 400C.

When the temperature of the air is greater, and relative humidity is lower, its ability to absorb moisture increases. When the temperature is lower, its ability to absorb moisture also decreases.

This low dew point of honeycomb dehumidifier helps you achieve more uniform and efficient moisture removal.

How silica gel increases the efficiency of honeycomb dehumidifier?

A desiccant is a non-metallic solid that absorbs moisture to cause the surrounding air to become drier because of its affinity for water.

Desiccants are used for many applications and are available in different forms, such as silica gel, calcium sulfate, magnesium sulfate, desiccant packs, etc. Among all other desiccant silica gel is the best ineffective moisture absorption. The reasons which make silica gel one of its kind are as follows:

Silica Gel Desiccant

Silica gel has the ability that it does not catch fire. It is non-flammable; thus, if you are going to use a dehumidifier as a dryer, then heat will not affect it. Silica gel can absorb moisture to almost 40% more than its weight.

The shelf life of the silica gel honeycomb rotor is comparatively longer, and you can reuse it as many times as you want after regeneration. This material is chemically inert, which means it will not react or disrupt other materials with time.

The size range of silica gel varies, and you can use it the way you want or as per your needs. All these features of silica gel increase its demand as the best desiccant to use in honeycomb dehumidifiers.

How can you convert a dehumidifier into a dryer with an optional heater and temperature controller?

A honeycomb dehumidifier is a unique dehumidifier that you can use as a dehumidifier and dryer. The option exists to add the heater and temperature controller to turn your only dehumidifier into a dehumidifier and dryer.

Combining a dehumidifier and a dryer will speed up the moisture removal process, and the end material contains almost no moisture.

The heating coil works as a heater that heats the dehumidified air after loosening its moisture to the honeycomb rotor. The temperature controller provides a great aid in this process. With a temperature controller, you can control the temperature of the air you want to achieve.

The correct temperature requirements depend on the type of material you will dry and the moisture content within the material. You should pay attention while choosing the temperature because the excess temperature may affect the material characteristics for longer periods.

How does an air filter prevent contamination of the honeycomb rotor in a honeycomb dehumidifier?

Air Filter is a filter used to remove dust from a gas flow. It can protect the honeycomb rotor from contamination caused by dust. Because a honeycomb dehumidifier has a honeycomb rotor to collect the water, it must provide good protection from dust. The protective effect this machine has comes from designing a special air filter.

As the honeycomb dehumidifier uses ambient air, there are chances that impurities, dust, or debris are present within the air; therefore, it is necessary to have an air filter in your honeycomb dehumidifier.

Dehumidifiers that are not properly filtered can contribute to bacterial propagation, which will, in turn, encourage the growth of mold and mildew.

There are two kinds of air filters–single-layer and double-layer. The former can separate and absorb large particles, while the latter can completely separate microorganisms, such as pollen, dust, virus, and spores. So, it is crucial to choose a suitable dehumidifier for good results.

The only thing you need to do is to clean your air filter periodically to prevent any form of dust buildup. The cleaning it needs depends on the type of environment you are working in and the frequency of usage. If you work in a harsh environment and frequent use, your honeycomb dehumidifier filter needs regular cleaning.

What hygroscopic materials can you dry using a honeycomb dehumidifier?

There are various hygroscopic materials that you can dry using your honeycomb dehumidifier. Some of the widely used materials are as follows:


Polycarbonate is a thermoplastic material produced by polymerization and has good thermal, mechanical and chemical resistance compared to other plastics.

Polycarbonate or PC is a lightweight material that does not rust or corrode. It is hygroscopic and has a good affinity for water; therefore, before processing, you need to dry it for high-end products.

Polyethylene Terephthalate

Polyethylene terephthalate (PET) is a thermoplastic polymer resin of the polyester family and is used in various products, including bottles for beverages, construction materials, automotive components, and grocery bags.

PET has excellent basic properties, such as chemical stability, processability, low-temperature performance, and heat resistance. Suppose the moisture content is present, and you process it. In that case, it will result in poor quality and deformed products, so you can process it after proper drying and dehumidifying in a honeycomb dehumidifier.


Polyurethane is a natural and synthetic material used to make various products from automobiles to furnishings. These include mattresses, bedding, carpeting, shoes, and athletic equipment.

The good thing about polyurethane is it is flexible, lightweight, and durable; the bad thing about it is that it holds on to moisture. Therefore, it is necessary to dry it before further processing completely.

How honeycomb dehumidifier impacts the efficiency of the plastic industry?

With the global plastic industry growing rapidly, the need for specially designed industrial honeycomb dehumidifiers has also increased. You cannot ignore the importance of honeycomb dehumidifiers.

The honeycomb dehumidifier is used in the plastic industry to achieve multiple benefits. The dehumidifier enhances the efficiency of the plastic industry, and it is important to understand its role in the industry.

This dehumidifier diminishes atmospheric pollution which also helps avoid the greenhouse effect and decreases the drying time, thus allowing additional processing time. It also increases the quality of the product within the warranty period.

The honeycomb dehumidifier is moveable, and it has wheels attached to the base, which allow you to carry your dehumidifier anywhere you want. There is no labor required to move this equipment. Even a single person can aid in transportation.

How to choose the right honeycomb dehumidifier?

You need to consider several factors before choosing the right honeycomb dehumidifier. Some of the main factors are as follows:


Size is one of the most important things you must consider before buying a honeycomb dehumidifier. This concern has to do with its performance and efficiency.

The capacity of a unit will vary based on the unit’s size and how much moisture it can process each day. You don’t need to choose the biggest one. It would help if you bought based on your need for humidity control.


The product’s price is one of the key factors in determining the purchase. You should consider the cost of the honeycomb dehumidifier before buying to access it if you have the proper budget to help you make a purchase.


The life of a honeycomb dehumidifier plays a great role in selecting your honeycomb dehumidifier. How long it will last will help you understand how long you will be going to take benefit from the honeycomb dehumidifier. In other words, it will allow you access to the durability of the honeycomb dehumidifier.

How do portability and compact design facilitate the operation of honeycomb dehumidifiers?

The compact design and portability of the Honeycomb Dehumidifier effectively induce the system’s operation. This dehumidifier is easy to use. It has wheels that allow you to move it around your facility easily.

The portable honeycomb dehumidifier comes with a compact design, perfect for small spaces. The circular shape also helps it be more compact and lightweight than other dehumidifiers in the market.

Thus, you can adjust more machines besides this equipment. This will save up your space and time. You don’t need to hire extra labor to move your honeycomb dehumidifier. Hence this will also help you save additional expenses.

What is the working principle of a honeycomb dehumidifier?

The honeycomb dehumidifier working principle is simple and is as follows:

The operation of a honeycomb dehumidifier starts with the intake of ambient air. The ambient air first passes through the air filter, which removes any impurities and then directs it toward the blower.

The blower pressurizes the air and then allows it to pass through the desiccant material, also known as the honeycomb rotor. After passing through the honeycomb rotor, if any moisture content is present, it gets removed through the air. Now the air is directed toward the hopper containing the material you want to dry.

Working Principle

The dried air then moves through the hopper and passes through the material, taking up moisture if present. After that, the air then again goes to the filter, and in this way, the cycle continues.

If the heater and temperature controller are added to your honeycomb dehumidifier, the air, after passing through the honeycomb rotor, goes into the heating element where its temperature rises to the set limit and then goes into the hopper.

As you already know, warmer and dry air more quickly helps eliminate the moisture from the material that you are going to dry.

How would you define desiccant material in honeycomb rotor, and what desiccant materials exist to use in honeycomb dehumidifier?

Desiccant material is a drying type, usually consisting of hygroscopic materials or chemicals that attract and hold water molecules from the air.

In a honeycomb dehumidifier, desiccant material acts like a sponge by absorbing water, which reduces the amount of moisture in the air. It has strong absorption and adsorption capacity, removed from the air to minimize atmospheric humidity.

Some of the main desiccant materials include:

Calcium Sulfate

Calcium sulfate is an inorganic compound primarily used as a desiccant in the agriculture industry and as a filler for plasters and types of cement and in cosmetics. Calcium sulfate absorbs moisture from the air to prevent it from becoming too humid and moist.

Activated Alumina

Activated alumina, also known as aluminosilicate desiccants, comprises aluminum oxide (alumina) combined with various amounts of silicon and oxygen.

It is created by burning clay containing aluminum in an oxygen-rich kiln at high temperatures (above 1000 degrees Celsius). It’s ‘activated’ due to the chemical process involved. The product is called ‘activated’ to distinguish it from the naturally occurring form of alumina.

Calcium Chloride

Calcium chloride is a chemical compound that absorbs water. It’s sold in granular form in supermarkets. Calcium chloride is used to make dehumidifiers, create artificial, controlled conditions, and help absorb moisture from the air.

How do air down blowing and cyclone exhaust impact the performance of honeycomb dehumidifiers?

Honeycomb dehumidifier works on the principle of air down blowing. It blows powerful air down through the duct located in the hopper. This effectively spreads the air uniformly throughout the hopper.

No particle will remain undried because of uniform dry air distribution. This will help you dry the bulk quantity of material in less time. This plays a great role in industries where they need to process large amounts of plastics in a very small-time span.

How PID temperature controller help you control the accuracy of the honeycomb dehumidifier?

A PID temperature controller is more accurate than other thermostat controls for a wide variety of temperatures. The PID temperature controller does not have any dead time and can precisely control temperature and time more quickly, making it very suitable for the control of honeycomb dehumidifier operation.

With a Honeycomb dehumidifier, it is necessary to control the environment’s temperature. The PID temperature controller is a sensor that measures temperature continuously. With the help of a built-in microprocessor, it maintains the set temperature and controls the temperature within preset limits by adjusting the heater device.

The high-quality control PID temperature controller is highly resistant to heat and allows the full utilization of the system’s performance. This controller has an inbuilt mini LCD which enables the operator to monitor the current setpoint, setpoint value, and the actual temperature range, among other useful information.

What safety measures do you need to follow while operating your honeycomb dehumidifier?

Safety measures are part of any product you should take care of. When you buy honeycomb dehumidifiers, it is important to follow safety measures to use them effectively.

First, read the instruction manual in the pack for your safety, and then switch on the dehumidifier. Take care of all the knob settings like humidity, fan speed, and power mode.

Keep the children away from the honeycomb dehumidifier while operating it. Always use protective gloves and goggles to prevent your skin and eyes from accidents.

Frequently inspect air filters and keep cleaning them to maintain the proper functioning of your honeycomb dehumidifier.

Ensure no uninsulated wiring exists for your honeycomb dehumidifier to prevent any accident from happening.

Ensure the person operating your honeycomb dehumidifier has enough skills and professional experience. This will help you make use of the honeycomb dehumidifier at its peak.

How would you define regeneration heater and regeneration blower in honeycomb dehumidifier?

The regeneration heater and regeneration blower have a very important role to play. They are widely used in the regeneration process. It takes place on the second half of the honeycomb rotor.

This process removes the moisture from the desiccant material by passing warm air into the desiccant and then exhausting this air directly out of the honeycomb dehumidifier.

The regeneration heater is used to increase the ambient air temperature taken in from the atmosphere. The heater is in the form of a heating coil. You can control the heater’s temperature directly through the PID temperature controller.

The temperature range varies from the desiccant material. Each desiccant material requires a particular field of temperature to get dried effectively. It would help if you considered that temperature range.

The regeneration blower’s main role is to force the air or impart pressure. This will evenly distribute the air throughout the desiccant material and increase regeneration efficiency.

How regeneration process in a honeycomb dehumidifier speed up the drying process?

If the regeneration is not carried out, then each time the desiccant moisture level reaches its peak, you need to remove or replace the material from the honeycomb dehumidifier.

The honeycomb rotor works in two halves. In one half, the normal process occurs, while in the second half, the regeneration process occurs. This will prevent you from taking out the desiccant material from the honeycomb dehumidifier.

Regenration Process

This will elongate the timespan for which you can use your desiccant material without replacing or removing it. This will increase your efficiency because you can use the same desiccant regenerating again and again.

The regeneration process can quickly remove moisture from the material, speed up the drying process, reduce operating costs and increase convenience for industrial and commercial facilities. You must get one to speed up your drying process and increase productivity.
