Walk in chamber comes in a variety of sizes, from a small box that fits on the bench top to a room-sized chamber for large objects or for testing large batches of product simultaneously. Temperature ranges from -60° C to 150° C and relative humidity ranges between 20% and 90% are available. A temperature humidity walk in chamber can also be used when constant climate conditions (temperature and/or humidity) are needed for product testing.
A walk-in chamber is a type of environmental test chamber that is designed to simulate a range of temperatures and humidity conditions. These chambers are commonly used in various industries such as aerospace, electronics, automotive, and pharmaceuticals to test the performance and reliability of their products under different environmental conditions. The chamber’s walls and door are insulated to maintain the desired temperature and humidity levels, and there are provisions for controlling and monitoring various parameters such as temperature, humidity, airflow, and pressure.
Walk in test chamber simulates the effects that a range of temperature and humidity conditions have on a product or material, for example telecommunications equipment or photovoltaic solar panels that are exposed to outdoor temperature and humidity conditions. These chambers can be configured to meet specific testing requirements, including size, temperature ranges, humidity ranges, and other parameters, making them a versatile tool for a wide range of environmental testing applications.

Today we are processing a 10 CBM walk in chamber (10000 Liters) assembly work. I have taken some photos for Wewon’s employees working moment, The walk in test chamber’s Testing Room Size: 2500*2000*2000 (W*D*H mm), Refrigeration System: France Tecumseh, Germany Bitzer Compressor with 10 years quality guarantee.
There also has a long size heating for hot temperature testing purpose. The cooling rate, and heating rate can be customized based on customer’s testing requirement. For the installation work, We will guide the customer by user manual when the walk in chamber arrived there. We can go to customer’s plant for assembly work as well. If you have the interest and trying to know more, Please let me know. Thank you.
Last week, We have shipped 2 pieces Walk-in Type Temperature Humidity Chambers to Mead Johnson Nutrition (GuangZhou) Co., Ltd. One is 8 cubic meters, another one is 15 cubic meters. Mead Johnson is a 100 years history USA brand, Mainly produce the milk powders for babies. They just received two Walk-in Type Temperature Humidity Chambers from Wewon Environmental Chambers Co., Ltd. , one measuring 8 cubic meters and the other 15 cubic meters.
These chambers are designed to simulate a range of temperatures and humidity conditions, enabling Mead Johnson to test the performance and durability of their milk powders under different environmental scenarios. Of course, The walk in chambers can also be used for safe storage of milk powder products. The fact that Mead Johnson ordered two chambers of different sizes indicates that they have specific testing needs and are committed to thorough and accurate testing.
Here are the calibration certifications before shipment which comes from the professional China quality assessment and authentication organization: Guangzhou Institute of Measurement and Testing Technology. These verification certificates are the requirements for quality verification put forward by customers before the production of walk in chamber. As an environmental equipment manufacturer with excellent quality awareness, We have reasons to accept customer requirements.
While certifications can be helpful in building trust with customers, I have to say that they should be combined with other best practices for building trust, such as consistently delivering high-quality products and services and clear communication with customers. We know this truth! Additionally, It’s important to thoroughly research and evaluate any certification organizations to ensure they are reputable and provide accurate assessments.
| ● | Question: A dehumidifier in walk in chamber will be required to avoid icing during testing. Humidity range – as low as possible |
| ● | Answer 1: Yes, We understand this point. We have the dehumidifier system to avoid icing problem during testing. |
| ● | Answer 2: This is the normally and reasonable request when customer doing testing work, especially for thermal shock chamber’s rapidly temperature change testing. We are familiar with this design, Please don’t worry ! |
| ● | Question: Preferably the dehumidifier and heating/cooling unit to be contained in one unit. |
| ● | Answer 1: ok, In fact. We are professional cooling refrigeration manufacturer for 18 years. |
| ● | Answer 2: We are familiar with the cooling structure, When you ordered to us, We will issue this custom design for cooling refrigeration to show you how we work. After get your approvement, Then we wil start to make this walk in chamber for you. There no any risk for you. |
| ● | Question: Walk in chamber should have the ability to cool/heat all test items to a range of -50°C to 75°C |
| ● | Answer: ok, We have no problem to process this testing requirement. We also accept some custom design and lower cooling temperature range. |
| ● | Question: 305mm x 305mm (minimum) viewing window on the front door for walk in chamber is required, Is it possible ? |
| ● | Answer 1: ok, Our standard size for viewing window is 250mm x 300mm, |
| ● | Answer 2: If you request a custom size viewing window, We accept our choice and will make the view window for you based on your requirement. |
| ● | Question: Walk in chamber will need to be designed to be taken apart and reassembled multiple times |
| ● | Answer: Yes, Due to the walk in chamber with quite big size reason, We will install this walk in chamber with assembly way, and you can take apart yourself in case you need to move to another place. |
| ● | Question: Ease of assembly as a walk in chamber and also cooling units will need to be designed to be quickly attached and removed |
| ● | Answer: Yes, This is our design what we will process for you. When you ordered to us, We will issue our design to you, You will see we are right and this is what you need. Thank you. |
| ● | Question: Walk in chamber consist of 4 walls that attach directly to the firing bay floor surrounding the firing table and mounted gun. The bay floor is not insulated |
| ● | Answer: Yes, We understand the bay floor is not insulated. To keep the environmental chamber keep a good cooling condition inside, We will use the insulate glue and mineral wool to avoid the cool air and hot air come out. |
| ● | Question: The walk in chamber attachment is made with 1in bolts spaced at 24in intervals |
| ● | Answer: Yes, This is reasonable, We also use insulate glue there to make sure the quality is guarantee. |
| ● | Question: I have a special request. Can a walk in chamber be built around a part ? |
| ● | Answer: Yes, The walk in chamber build aroud the testing part is ok. We have some experience on this design, and we are familiar with this design. |
| ● | Question: The testing item has, 3000kg, steel part that is attached to the floor. The ideal temperature range is -50°C to 160°C and will also need a humidifier to reduce icing. The size is 8’W x 10’L x 7’H . Can this be done ? |
| ● | Answer 1: I noticed the temperature range request is -50°C to 160°C, We can make it ! |
| ● | Answer 2: But I am not sure why you request a -50°C to 160°C, Because when the wall going to temperature upto to 100°C, It will be aging rapidly. And it can not be tested for many hours. The wall not made by steel, They are the insulation plate, It can not afford the highly temperature always ! |
| ● | Answer 3: Meanwhile, We have the temperature oven, the MAX temperature is +250C, Maybe you can use our temperature oven for highly temperature test. This may more reasonalbe solution for your reference. |
