As with any form of technical equipment, test chambers reach a point when they do not perform according to industry specifications and requirements. When this occurs, companies that specialize in rebuilding, fabricating, and repurposing test chambers purchase the chamber from the original owner and put it through a rebuilding process.
Since test chambers are a long way from a used car, they require meticulously detailed processing to make them sufficiently capable of performing their functions. When a chamber is picked up, it is cleansed of any chemicals, liquids, and hardware, actions that are designed to guarantee safe transport and provide a first assessment for the refurbishing team. The data collected is helpful in determining the viability of the used chamber.
From the initial appraisal, the next step is to do a more thorough inspection to assess what can be refurbished or needs to be replaced. Some of the worn parts may have the potential of being repaired and reinstalled, which can save time and money. Every element of the chamber is carefully inspected to ensure when it is finished it can perform as if it were new. In most cases, twenty technical and nontechnical components are examined, evaluated, and assessed designed to assess every part of the chamber.
For a test chamber to provide accurate and reliable data, it has to be a sterile and uncontaminated environment. For a refurbished chamber to be put back in use, it needs to have a thorough cleaning to remove any extraneous elements or chemicals. A well designed test chamber will produce data that determines whether a product is ready for the market. Flawed or corrupted data can lead to inaccurate and poor decisions. For this reason, the cleaning phase is an essential part of the refurbishing process.
Once cleaning is completed and parts have been replaced, the next step is to test the chamber performing all of its functions. The purpose of a testing chamber is to place products in harsh environments to see how they endure. When testing a refurbished chamber, all of the conditions from high or low temperatures to limited atmosphere have to be programmed into the chamber to see how it performs. Companies that refurbish test chambers have very strict guidelines and specific requirements to be met before approving a refurbished chamber for sale.
The cost of refurbished chambers varies depending on size. A counter top test chamber can be as low as a couple hundred dollars while walk in versions can be over a thousand dollars or more. Regardless, a refurbished test chamber is much less than a new one and provides the same type of data.
