Dehumidifier laboratory equipment

Types of Dehumidifier Laboratory Equipment

A dehumidifier laboratory equipment is a system used in laboratories to manage humidity levels. Laboratories conduct sensitive tests and experiments that require specific environmental conditions to yield accurate results. Depending on the mechanism used to remove moisture from the air, the types of dehumidifiers are as follows:

• Desiccant dehumidifier: In desiccant dehumidifiers, adsorption is used to eliminate moisture from the air. A desiccant material with low humidity absorbs the water vapor in the air. Then, through a hot air regeneration wheel, the collected water from the saturated wheel is expelled, and the cycle continues. This kind of dehumidifier lowers humidity levels even at low temperatures. It is quieter when compared to other types of dehumidifiers.
• Draining dehumidifier: Condensation is used for moisture removal in draining dehumidifiers. Here, air is cooled to remove the moisture, similar to how a cold drink sweats on a hot day. Water collects in a tank and may be drained manually or automatically. This type of dehumidifier works best in warmer climates and can lower temperatures by up to 39 degrees. Although draining dehumidifiers are less expensive than desiccant dehumidifiers, they are more thermally efficient.

Depending on the purpose, other kinds of laboratory dehumidifiers include:

• Portable dehumidifier: These can be moved easily from one place to another. Portable dehumidifiers require less maintenance and installation, making them a convenient option. In laboratories, portable dehumidifiers can lower humidity levels in specific areas where delicate instruments and samples are kept.
• Commercial dehumidifier: Commercial dehumidifiers are larger in size as compared to others. They run continuously and need more humidity control. In laboratories, commercial dehumidifiers work around the clock to ensure that humidity levels stay within a specific range.

Laboratories are essential for various industrial processes, including pharmaceuticals, chemicals, food and beverages, and biotechnology. Humidity control helps maintain product quality and prevents damage to sensitive equipment and instruments. A wide range of dehumidifiers is available to meet different applications and capacity needs.

Functions and Features of Dehumidifier Laboratory Equipment

The core function of laboratory dehumidification is controlling and maintaining ideal relative humidity levels. This is crucial for activities like material testing, equipment calibration, and specimen storage.

Dehumidifiers work by drawing in damp air, lowering the humidity levels, and releasing drier air. To achieve this, laboratories use various dehumidification equipment that depends on the size and scale of the operation:

• Desiccant wheels: They absorb moisture from the air using specialized materials that highly attract water vapor and progressively release it through a heated regeneration process. These wheels can achieve low humidity levels.
• Heat exchangers: These use refrigeration principles; they are also known as rotary dehumidifiers. Hot, moist air passes over cold coils, causing water to condense that can be collected or drained away.
• Electronic dehumidifiers: They have similar functions to rotary dehumidifiers; only their operation is carried out using an electric motor.

To maintain ultra-low humidity dew point levels in laboratories, specialized dehumidifiers achieve these features:

• Humidity controller: It has sensors and programmable settings that help automatically maintain desired humidity levels.
• Air filtration: Filtration systems capture particles like dust, mold spores, and volatile organic compounds (VOCs) from the laboratory air to improve air quality and prevent contamination.
• Corrosion resistance: Laboratories that deal with caustic or corrosive materials require dehumidifiers built with materials resistant to chemical damage.
• Explosion proof: These dehumidifiers are designed and manufactured for use in hazardous environments where flammable gases, vapors, or dust are present. They have safety features that prevent ignition of the surroundings.

Scenarios

• Research facilities:

  Dehumidifiers are essential in research facilities to maintain optimal humidity levels for accurate research results. A variety of scientific research depends on the dehumidifying system to keep the projects in order. In a materials research laboratory, where they explore new substances and look into how different things interact with each other, having the right humidity is super important. When testing under specific conditions, a precise humidity level is required. A good dehumidifier helps keep everything accurate by maintaining the necessary environment and preventing excessive moisture that could interfere with the experiments. Keeping the humidity at the right level ensures accurate data and helps them make new materials and understand their properties without any mix-ups.

• Pharmaceutical production and storage:

  Dehumidifying is a critical process in the pharmaceutical industry for several reasons. Pharmaceutical products must be kept below a certain level of relative humidity throughout their shelf life to avoid degradation and maintain quality. A dehumidifier laboratory equipment helps to control moisture levels, which prevents the breakdown of active ingredients and ensures the stability and efficacy of drugs.

• Food and beverage testing labs:

  Dehumidifiers have an important role in food and beverage testing labs by controlling humidity levels during product evaluation and testing. Different types of food have specific moisture requirements. A dehumidifier can keep the humidity level consistent, giving accurate data on how food will act under normal conditions. It helps to prevent any corrosion that might affect the testing results. The device helps keep the air quality good and stops the growth of mold or harmful bacteria, ensuring a safe place to work. By controlling the environment with a dehumidifier, food and drink testing labs can follow the rules and have reliable results. This helps them study the shelf life, quality, and safety of products.

How to Choose Dehumidifier Laboratory Equipment

Laboratories have specific requirements when it comes to choosing dehumidifiers. This is because, in laboratory settings, the humidity levels fluctuate. Therefore, it is important to use a dehumidifier that maintains optimal humidity levels for each specific laboratory. Below are important factors to consider when choosing dehumidifier laboratory equipment.

• Size

  The right size dehumidifier should be chosen depending on the laboratory size and the square footage. Small laboratories can use portable dehumidifiers, while larger laboratories may need industrial dehumidifiers to effectively reduce humidity levels.

• Humidity Types to Target

  Targeting humidity types is important because different laboratories prefer different humidity levels. Laboratories such as biological, industrial, pharmaceutical, and chemical labs prefer targeting different humidity percentages. For instance, a general laboratory humidity level in percentages should be between 45-55 percent. However, in a pharmaceutical lab, the humidity level should be lower than 40 percent and targeting a higher dehumidifier would be ideal for achieving this percentage.

• Applications

  Applications are important to consider because different laboratories serve different purposes. For example, if the laboratory is being used for research or storage of sensitive materials, then a dehumidifier with sophisticated control is needed. This is to provide precise humidity control. On the other hand, if the laboratory is being used for general purposes, then a basic model will work perfectly.

• Humidity Control Systems

  The humidity control system is responsible for monitoring and controlling the laboratory’s humidity levels. This is important because it enables choosing a dehumidifier with a laboratory humidity control system that meets the laboratory’s needs.

• Testing Standards and Certifications

  When it comes to laboratories, standards and certifications are very important to meet specific requirements. For example, laboratories working with pharmaceuticals or food industries should comply with FDA standards. This is to ensure that the equipment is safe and suitable for use in a laboratory environment.
