What is lab dehumidifier?

dehumidifier-laboratory-equipment
As a multi-billion-dollar global business, the role of the manufacturing environment plays a critical role in the quality of the end product in the pharmaceutical industry. A variety of environmental factors can have an impact on product quality, the most important of which is atmospheric humidity. A lab dehumidifier is a must for any manufacturer of tablets, pills, capsules, and other pharmaceuticals. In the absence of humidity control in any kind of laboratory equipment, variations in humidity levels in the manufacturing environment can wreak havoc on tablet coatings. Furthermore, the absence of dry air can create challenges in the flow of powders, which can have a ripple effect on filling gelatin capsules with powdered ingredients. Properly controlled humidity levels are also useful in terms of ensuring the end product retains all its core properties and functions as it’s designed to do. The pharmaceuticals sector is not the only one in the industry to use dehumidifiers for laboratory equipment and workplaces. The broader life sciences industry also employs humidity control system technology.

The laboratory dehumidifier is a device that controls and regulates the environmental humidity in the laboratory. Usually, lab dehumidifiers consist of compressors, heat exchangers, fans, water containers, housings, and controllers.

Lab dehumidifier working principle

The fans inside the lab dehumidifier pump the humid air into the machine and pass through the heat exchanger, at which time the water molecules in the air condense into water droplets. After treatment, the dry air is discharged from the machine, so that the cycle of indoor humidity is maintained at the appropriate relative humidity.

Why do laboratories need dehumidifiers?

Nowadays, many workplaces require dehumidification equipment to assist in controlling the humidity in the air. In addition to workshops in the technology industry, laboratories are undoubtedly in great need of dehumidifiers. Whether it is a life science laboratory or a pharmaceutical and chemical laboratory, the demand for temperature and humidity control is very strong.

In addition to life science laboratories and pharmaceutical and chemical laboratories, there are many types of laboratories. Depending on the characteristics of laboratories, they can be divided into dry and wet laboratories, main and auxiliary laboratories, conventional and special laboratories, and hazardous laboratories. The control of air humidity in the workshop may only require a general range, but the control of air humidity in the laboratory is very stringent because environmental factors can have an impact on product quality and one of the most important factors is atmospheric humidity. Environmental factors can affect the characteristics and performance of measurement equipment in the lab, so R&D labs need to meet strict temperature and humidity requirements.

Why do lab storage rooms need dehumidifiers?

A. Most of the instruments stored in the laboratory storage room are electronic components, optical lenses, and other instruments with high precision. If these precision instruments are stored in a humid storage room for a long time, it may rust them and destroy the accuracy, thus bringing inaccurate results to the experiment.

B. The laboratory storage room usually stores some liquids, powders, metal products, and other materials that need to be used in the experimental process. These materials cannot be affected by moisture preservation, nor can they be saved in an overly dry environment. In other words, a high humidity environment or low humidity storage environment is not suitable for the storage of experimental materials.

Why laboratory dehumidification is so important?

In the process of conducting experiments, different laboratories have strict requirements on the temperature, humidity, and cleanliness of the indoor environment for different experimental operations. Generally, the relative humidity of the laboratory should be manipulated at about 45%-55%. Providing a laboratory environment with stable humidity for experimental operations can effectively ensure the smooth conduct of experiments and the accuracy of data.

In an ordinary chemical laboratory, for example, high air humidity can cause changes in the form and properties of chemical reagents, such as sodium peroxide, as well as metallic sodium, potassium, and calcium substances can absorb the moisture in the air to form saturated solutions. They react with the water in the air, releasing large amounts of hydrogen gas, which then gives off heat. This is a major safety hazard, as it could lead to an explosion in the event of improper handling.

Humid air can also lead to the continuous multiplication and spread of microorganisms (especially fungi) in the laboratory. If they keep multiplying and spreading, they can contaminate the sample and then decompose it, leading to experimental failure. In addition to the laboratory storage room, some high-precision instruments are also stored in the laboratories. The good or bad of these fine instruments indirectly affect the accuracy of the role of the test or not. A high temperature and high humidity laboratory environment are not suitable for the use and preservation of high-precision instruments. Moisture, mold and metal oxidation, and other hazards are always harming the high-precision instruments. These properly cause the machine to eventually fail to operate. The subsequent repair is not only time-consuming and costly but also seriously affects the efficiency of the experiments conducted. Failure of experimental objects or experimental equipment can lead to failure of experiments, which not only leads to inaccurate experimental results but also may be a safety hazard. Therefore, controlling air humidity is very important for laboratories to save resources, improve the utilization of instruments and reagents, and reduce the operating costs of laboratories.

How to control the air humidity in the laboratory?

You can configure a dehumidification system in the laboratory to solve the problem of humidity control in the laboratory, which is commonly known as lab dehumidifier.

Types of lab dehumidifier

At present, lab dehumidifiers are mainly divided into condensing dehumidifiers and rotary dehumidifiers.

A. Condensing dehumidifiers

The working principle of condensing dehumidifiers is very simple. For example, you take a bottle of beer out of the refrigerator and put it on the table. After a while, you see the beer bottle covered with small droplets of water. In the same way, this is the water vapor in the air will condense into liquid water when it gets cold. According to this principle, the condensing dehumidifier pumps humid air into the machine, so that the compressor drives the heat exchanger (evaporator and condenser) to condense the moisture in the air into pin water beads collected, and then release the treated dry warm air. Thus, you can reduce indoor humidity by repeatedly circulating humid air through the condensing dehumidifier.

The advantages of condensing dehumidifiers are a mature technology, low price, and energy saving. However, they also have disadvantages. First, the noise is large (compressor, fan noise, and machine resonance). Second, low-temperature dehumidification efficiency is low or even unable to work, which means that condensing dehumidifiers do not operate properly in low temperature and high humidity conditions. Therefore, condensing dehumidifiers are suitable for laboratories with ambient humidity requirements of 45% or more.

B. Rotary dehumidifiers

The working principle of the rotary dehumidifiers is to continuously and continuously provide dry air with low dew points by continuously repeating the moisture absorption and regeneration action without affecting the air circulation. Figuratively speaking, a rotor dehumidifier is like a dry towel that absorbs the water from the air and discharges the moisture by drying. The biggest difference between it and condensing dehumidifier is that condensing dehumidifier is to achieve the purpose of condensing and dehumidifying by lowering the temperature, while the rotary dehumidifier is to dehumidify by heating up and condensing. The rotor dehumidifier is suitable for the pharmaceutical industry, lithium industry, food processing industry, cold storage, laboratory, aerospace, and other workplaces and industries.

Advantages of rotary dehumidifier

a. Rotor dehumidifier is through a constantly rotating moisture absorption turntable to absorb the water vapor in the air, and then make the heated high-temperature dry air to take away the humidity on the turntable, to achieve the purpose of dehumidification through room temperature condensation in high-temperature wet air.
b. The dehumidifying ability of the rotor dehumidifier is not affected by the ambient temperature and humidity, which means it can dehumidify under any temperature and humidity conditions.
c. High moisture absorption capacity in low temperature and low humidity environment. Rotor dehumidifiers can be used in the field of dehumidification requiring a dew point temperature as low as -65℃. They can control the temperature to 1%-40% relative humidity, or even below 1%.

Disadvantages of rotary dehumidifier

a. There is no heat pump, so heating the air is entirely dependent on energy conversion to achieve, resulting in its higher energy consumption.
b. The rotary dehumidifier has limited moisture absorption efficiency and regeneration efficiency, so its dehumidification capacity is much lower than that of condensing dehumidifier.
