3 major things to consider while buying environmental chamber

Environmental Chambers are utilized for a few purposes and various experiments, so it becomes imperative to pick the correct one. Similarly, as with any significant purchase, a few things must be considered before making the final choice. Many individuals are enticed to buy on cost only.

However, as we probably are aware, you get what you pay for. Quality, reliability and service after the deal all mean the estimation of your purchase. Over the life of the unit, that can turn into an expensive mistake. Different kinds of test chambers are accessible. Your application is principally going to decide the kind of chamber you need. The better you transfer that data to your provider, the better your chamber will coordinate your needs.

Temperature Range

The significant difference is the temperature extend in which the chamber will work. Most manufacturers have a standard high temperature scope of 177°C to 190°C for reach-in chambers and welded walk-ins. To cool the chamber, a few choices are available. The two major classifications are disposable refrigerant and precisely cooled. The two most famous refrigerants are fluid nitrogen (LN2) and fluid carbon dioxide (CO2). Both of these gases are environmentally safe and can be vented to the atmosphere. One must be cautious with the temperatures of the environmental chamber as a miscalculation can prompt extreme damage.

Humidity Range

Humidity is presumably one of the most misjudged topics when it comes to environmental test chambers on the grounds that the relative humidity (RH) rate is temperature explicit. Since the measure of moisture varies at each temperature, the chamber manufacturers use dew point to depict the RH confinement. Inside the chamber, there is a refrigerated curl controlled at 5°C or marginally beneath. To accomplish lower humidity levels, most manufacturers offer a low RH package.


Chamber construction is a basic zone that should be assessed when making a purchase. Most chambers have painted exteriors and stainless steel liners. It is easy to accept they are altogether assembled a similar way. In any case, when you assess the details, you will see differences that can enormously influence the long haul reliability of the chamber. When leaks happen in the stainless steel liner, a way is opened for moisture to travel all through the chamber, particularly when the chamber is utilized for temperature and humidity testing. Most chamber manufacturers use fiberglass protection. A point of consideration ought to be the access ports. As the pressure in the chamber goes all over during temperature transitions, the walls will deflect. Another region that can be compromised after some time is the place the refrigeration lines penetrate the stainless-steel chamber. The refrigeration lines generally are copper tubing. If any sharp edges touch the tubing, a refrigerant leak will create.
