Leading Humidity Chamber Manufacturers

Humidity chambers are also used as extended testing chambers to record the product’s reaction to elevated moisture when exposed for weeks or months. Depending on the product type and data required, different varieties of humidity chambers allow testing in static as well as dynamic states.

Construction of Humidity Chambers

Humidity chambers are constructed carefully so they can give accurate and reliable results regarding the product's performance. They are made of durable material that is capable of withstanding the conditions the chamber creates.

• The chamber is double-walled; it can be welded or modular. Welded wall is preferred, as it gives better sealing to avoid contamination.
• The sealing of the chamber is important to restrain any contaminant from entering. The sealing materials are rubber, glass wool, silicone, or other polymers.
• Cooling compressors and heating coils are installed to control temperature and humidity.
• For air supply air ducts, circulating wheels or fans are installed.
• Controllers are present in the chamber to maintain desired conditions.

Working of Humidity Chambers

Humidity chambers work on the principle of relative humidity. Temperature is the key factor in determining humidity level; therefore, these both work together. The humidity chambers work by the following process:

• A targeted dew point temperature is maintained, and then the chamber is reheated to a specified air temperature.
• This maintenance of constant dew points will produce constant relative humidity.
• The air from the conditioned area is passed through the water spray area within a closely controlled temperature.
• When this air passes through the water spray, it is cooled down to the water temperature and reaches saturation.
• Through a mist eliminator, the air leaves the spray chamber. This removes any excess water vapor present.
• An electric heater is used to heat up the air, and then it is retired to the conditioned space.
• The water spray temperature is adjusted automatically by the RH sensor.
• This method helps in achieving a precise humidity level in the chamber.

Methods of Humidity Generation

Steam Generators

• Steam generators are a method to produce humidity in the chamber.
• They are tank-type machines that have duly equipped immersion heaters.
• On the top of the chamber, cooling coils and heaters are present.
• The water is heated in the chamber, and steam is produced.
• This steam moves upward to the cooling coils and demands relative humidity.
• The water vapors produced in these generators are consistent.
• Big chambers can easily generate a high volume of moisture.

Atomizer

• An atomizer has a fine spray nozzle that is used to atomize water.
• Atomization is done in the mixing assembly.
• On entering the chamber, the atomized water is instantly heated.
• This creates a high level of humidity in the chamber.
• Atomizers are the best to use because they are simple to use, save electricity, are capable of generating huge amounts of steam, and have no issues with heater burn-out.

Water Bath

• A water bath is also a type of steam generator, but it is not an enclosed box.
• The water bath is placed in the mixing assembly along with cooling coils and heaters.
• When air enters the assembly, it immediately picks up vapors.
• Water baths are easy to clean and maintain because less boiling is required in this process.
• Less boiling means less mineral deposit in the chamber.
• Water baths are responsive due to the small amount of water.

Types of Humidity Chambers

Bench-top Humidity Chamber

Bench-top chambers are cost-effective and are used for testing small products. These are designed for research labs or small businesses.

Reach-in Humidity Chamber

These chambers have smaller footprints and are in a vertical configuration for easy access. These are designed with castors or wheels and come in several sizes.

Walk-in Humidity Chamber

Walk-in humidity chambers are in modular construction and can be installed as a single unit. These chambers are used by automotive, electronics, and battery manufacturers.

Drive-in Humidity Chamber

Drive-in chambers are big enough to test vehicles. In these chambers, all vehicle parts are tested under all climatic conditions.

Industries Using Humidity Chambers

Humidity chambers are widely used by industries such as rubber, pharmaceutical, automotive, aerospace, military, defense, plastic, electronic, medical, and battery manufacturers to check the validity and efficacy of their products before launching them on the market.
