Walk-in Test Chambers FAQ Guide

All your questions about walk-in test chambers are answered in today’s guide. Whether you want to learn about definitions, benefits, features, or applications, you’ll find everything here. Read on to learn more.

A walk-in test chamber is a test equipment which designed to test the heat, cold, dry, and moisture resistance of products and materials. The walk-in test chamber has quality functions and controls for effective testing of your products under any conditions.

Walk-in test rooms come in a variety of sizes and can be used to test large and small objects. For walk-in laboratories with large rooms, products, and materials can also be tested in batches at the same time, which is conducive to manufacturing. In addition, the walk-in test chamber simulates temperatures during the test, ranging from -60°C to 90°C, depending on the performance of the machine.

In terms of machine test functions, using a walk-in test room to test products is similar to a benchtop test room. However, for products and materials, benchtop test chambers are not suitable for large-scale product testing.

According to the survey, the walk-in high and low-temperature test chamber is used to test the heat, low-temperature, drying, and moisture resistance of various materials in various environments. It is suitable for electronic, and electrical appliances, mobile phones, vehicles, instruments, plastic products, metals, food, chemical, building materials, medical, aerospace, and other products quality inspection. You can modify your products according to the inner cavity size, inner cavity stacking, temperature range, temperature change rate, and other properties.

The types of tests that can be carried out in the walk-in high and low temperature (or temperature and humidity) test chamber include the following:

  • high-temperature test
  • low-temperature test
  • constant temperature and humidity
  • alternating high and low temperatures
  • alternating high and low temperatures wet and heat
  • environmental stress test

We use electronic expansion valve control. Innovative refrigeration systems from Germany and Japan, reliable performance, improved efficiency. Compared with traditional equipment, energy saving is 20% ~ 50%.

Walk-in Test Chambers

In many cases, companies buy walk-in rooms for different reasons. One of the most obvious needs is size. Large or oddly shaped products may not necessarily fit within the scope of a floor model lab, especially when you consider the airflow ratio (1:3 ratio of product volume to workspace volume).

Other companies, on the other hand, are opting for “walk-in” LABS. To accommodate a large number of products (for example, thousands of phones) at the same time, or to allow engineers to see the product up close during testing. The former can improve testing efficiency, while the latter is only possible if there is a large amount of internal workspace.

Walk-in rooms can be customized based on volume and shape, performance, air quality (if people spend time in the room), etc. If you want to separate the chamber space from the lab, you can add an anteroom.

So while you might find similar performance in a floor model (or desktop). But you can only achieve this level of customization with a walk-in test room.

Walk-in Test Chambers

1)Walk-In Stability Test Chambers Vs. Walk-In Performance Test Chambers

The test purpose of the chamber is another consideration. In terms of size and volume, all things being equal, walk-in performance test chambers tend to be more expensive than stability test chambers.

In fact, the stability chamber is designed for steady-state testing. Where they reach a set condition point and stay there. If you need a temperature cycle, you need a performance chamber. As performance levels increase, so do costs.

More advanced system components for boosters that reach extremely low temperature or humidity levels. Such as larger fan motors, larger compressors, evaporators, or sensors that measure high relative humidity levels. Has driven up the price of a walk-in test room.

2)Panel Build Vs. Structural Build

As you might imagine, the sheer size of the walk-in test room makes it difficult to deliver prefab. Manufacturers address this challenge by offering panel-built models. They build the components separately and then assemble the chambers on-site.

In addition, this reduces shipping costs, improves build efficiency, and gives you flexibility. If needed, you can disassemble the test box and move it (or reconfigure the walls). But this is not the same as a test chamber bolted to the floor.

Right now, the performance levels of our panel manufacturing chambers are limited. If you turn the temperature up too high, you increase the pressure in your workspace. You could blow the walls off completely. Similarly, high temperature combined with humidity can cause delamination and destroy the integrity of the chamber.

If you really need high-performance testing, you need a struct build. These walk-in models are made of solid steel and can withstand extreme temperatures and humidity. For context, the panels are built with no customization required, allowing a temperature range of -65°C to 85°C and relative humidity up to 85%. Structural buildings can withstand temperatures from -73°C to +538°C and relative humidity from 10% to 95%.

Since they don’t have the same design flexibility, the structure is more expensive to build. In this case, Engineers take time to get the right amount of design complexity before going into manufacturing.

1. Precise, high-precision temperature control. Because we use advanced air supply system design and electronic control system. Therefore, the test chamber can maintain better temperature uniformity than similar products.

2. The temperature range of the test chamber is wide and constantly changing. In addition, the room temperature can be flexibly set in the range of +5℃~ -60℃(room temperature +5℃~ -80℃). If you have a special request, we can create a higher-temperature project.

3. System protection function is complete and can guarantee secure long-term reliable operation.

4. The test chamber is equipped with smoke alarms to prevent your products from burning during aging. When the alarm is triggered, the power supply to the aging chamber will be automatically turned off.

5. We can create a walk-in high and low temperature and humidity test chamber according to your needs. We can also make the corresponding load rack for the load. What’s more, the test rack must be structurally solid and reasonable, simple to use, cute in appearance, and meet other requirements.

Walk-in Test Chambers

Needless to say, no two companies have exactly the same testing needs. Various standards, internal best practices, characteristics of the device under test (DUT), and performance and size considerations are taken into account. There are many things you need to do to find the right test room for you.

So, “How much does a test box cost?” The answer is not easy. Because even standard stock boxes have the customization possibility to change the price tag. Your purchase of a test kit requires a lot of research and support from an experienced manufacturer to break down your choice.

Actually, walk-in rooms are in a category of their own. Not only because they are designed to accommodate people except for large products, such as large prismatic batteries or large quantities at a time. And because each unit needs to be customized. There is no standard model.

Generally, a walk-in test room starts at about $85,000. However, this number can vary greatly depending on size and performance. Here’s more background information on walk-in rooms, and what you might have to pay.

In fact, walk-in test rooms are designed in different sizes, as well as the necessary functions. Use this to test your development for heat resistance, cooling, and moisture durability to ensure safety and performance. Walk-in test rooms come in different sizes. Examples range from small test rooms that can be placed on top of a workbench to larger room-sized test rooms.

However, benchtop chambers (also known as small environmental chambers) are very different from walk-in chambers based on their appearance and function. Benchtop rooms are ideal for humidity and temperature testing of products and materials to ensure adequate performance and safety.

In fact, the purpose of the walk-in test chamber and the bench test chamber is the same. This is to test the capabilities of products and materials by conducting a comprehensive evaluation of them under different temperature conditions. In addition, the benchtop test box is very portable and small in size. This makes it easy to test in a small space. As the name suggests, a bench room can be easily installed on top of a bench or table.

1) Types of tests performed in walk-in chambers and benchtop chambers

Walk-in test boxes, on the other hand, are used to test products that require large test boxes. For small products, batch testing can be done in a walk-in test box. Due to its portability and small design size, the bench room is suitable for testing small products. However, when it comes to the types of tests that can be performed in walk-in and benchtop test rooms, includes:

Storage test

  • Altitude test
  • Vibration test
  • Temperature and humidity test
  • Salt spray and salt forging tests
  • and many more

The walk-in test chamber solves your need for climate testing on complex and large equipment. Because some devices are difficult to test against other testing machines. In short, the walk-in test chamber and bench test chamber use advanced technology to effectively promote the product testing process.

2) Features of walk-in test chamber and benchtop test chamber

According to the survey, both walk-in and benchtop test chambers can stimulate different climates and environments to evaluate product safety and quality. In addition, the walk-in and benchtop test rooms have efficient technical components that are excellent for conducting temperature and relative humidity product testing.

Features of walk-in and benchtop chambers include:

  • The chamber is equipped with doors and windows with extensive thermal insulation for viewing, the dimensions of which may vary depending on the size of the chamber.
  • LED, LCD, or RH display and sensors for touch commands.
  • The chamber contains the air compressor and condenser to control the temperature inside the system.
  • The system can receive files and commands via USB, Ethernet, Bluetooth, and Wifi. Not all test chambers have these features.
  • Remote control for receiving commands.
  • Chamber compartment with shelves and shelves to keep specimens stable.
  • Access plugs and ports for connections and more

In summary, the above characteristics of the walk-in test chamber and bench test chamber determine the ability of the machine to test according to temperature and relative humidity. However, there is not much difference in function between a walk-in test room and a benchtop test room. Because as technology continues to advance, each test machine has a different function, which makes it suitable for testing.

3) Choose between walk-in test chambers and benchtop test chambers

It is important to note that determining the type of machine suitable for each product test depends on the size and capacity of the test room. Depending on the product you want to test, choosing between walk-in and benchtop rooms requires thorough research and evaluation of the different rooms.

In most cases, for testing large products, I recommend you use a walk-in test box. Because it is able to accommodate large products and materials, such as refrigerators, cars, etc. Therefore, when choosing between a walk-in laboratory and a benchtop laboratory, it is necessary that you determine the dimensions of the product or material that will be tested in the laboratory.

For manufacturing industries that produce products and materials of different sizes, it is necessary to choose a laboratory that can accommodate the testing of large and small objects, such as a walk-in test chamber.

It is important that benchtop test rooms are durable and efficient when accurately testing small-size products or samples in the initial stages of development. Therefore, before making the final choice between a walk-in or benchtop laboratory, it is essential that you take the time to assess the testing capabilities and storage needs of your product or material, including:

The material of construction of the chamber will determine its suitability for high-temperature applications. Its relative humidity range may vary in the test chamber.

#1. Other aspects

On the other hand, test chambers for external and internal functions such as air compressors and condensers. Used to lower and raise the temperature as needed. In addition, the testing machine’s power supply heats and cools the box system during the test.

Choose from chambers with trending features and the latest technology upgrades including touch LCD or LED, RH displays, sensors, and more

When testing the product, make sure the chamber has operable walls and doors with washers to prevent leaks. And check that the test room is equipped with a complete exhaust filter. To remove harmful air or gases during testing.

Walk-in Test Chambers

  • The walk-in high and low-temperature test chamber’s door lock may only be unlocked from the outside, making entry strictly forbidden unless under the direct supervision of an engineer.
  • Walk-in high and low-temperature test chambers require routine moisture removal treatments if not in use for an extended period of time to prevent equipment damage.
  • If the test chamber is used to heat test the products, they must be powered externally rather than directly by the equipment.
  • Do not immediately open the refrigeration compressor if the temperature in the high- and low-temperature test chamber is below 55 degrees. This will help to ensure the compressor’s safety.
  • If not absolutely necessary for the test, do not open the door or go inside the chamber. to prevent harm to people and equipment malfunction.
  • Avoid using gravity to open or close the test chamber door because doing so could cause the door to fail, causing unnecessary issues during the test as well as accidents.
  • It is completely forbidden to test prohibited materials in the walk-in high and low-temperature test chamber work area.
