Climatic and Environmental Chamber: the Comparison
At FDM, we distinguish standard climatic chambers from so-called environmental chambers. How do we make this distinction? Based on the application and consequently on the relative temperature range
The temperature range of the standard climatic chambers is mainly 0-70° (usually extendable down to -30/90°).
Environmental chambers, on the other hand, generally cover a range of -40/180° (that can also be extended down to -70/200°).
The reason for such wide ranges? The applications, which involve extreme climatic testing.
The uses of this equipment for climate control include:
- electronic components
- aeronautical sector
- military sector
- aerospace sector

Climate Testing for the Military and Aerospace Sector
Stability Tests vs Dynamic Tests
Questi test climatici estremi sono in contrapposizione ai test cosiddetti di stabilità, tipici dell’ambito alimentare, farmaceutico e cosmetico.
The products from these industries must maintain their organoleptic properties unchanged over time and are therefore tested at temperatures that do not vary over a long period of time.
The products of sectors such as military and aerospace, on the other hand, are subject, in their real life cycle, to significant thermal stress. to variable atmospheric conditions, to different pressures, which must not, however, have any influence whatsoever on the performance of the finished product.
We are talking about aircraft and spacecrafts, where every detail must be taken care of, in order to guarantee total safety, for the vehicle and its crew.
All these applications therefore require the possibility of programming automatic temperature cycles as a necessary feature, in order to faithfully reproduce every real situation products will face.
The tests requiring these temperature ranges are also called dynamic, due to the characteristics listed above
Climatic Chamber for Military and Aerospace Applications
Thermal shock tests for the military sector follow standards such as MIL-STD 883H - Method 1010.8, now a standard also for other applications, to check the reliability of the components that make up these products.
Stress test chambers of this type generally consist of a "hot" chamber at high temperatures and a "cold" chamber, with a plane that moves the specimen from one chamber to another, to simulate temperature shocks.
Per il settore aerospaziale, spesso si fa riferimento alle camere termovuoto (TVAC o TVC) che simulano appunto le condizioni dello spazio terrestre nei parametri di pressione e temperatura.
Climatic chambers for military and aerospace applications can have limited volumes but there are many cases in which their dimensions are extremely big: in this case we are talking about walk-in chambers.

FDM Environmental Chambers
FDM environmental chambers meet all extreme test requirements, in the different applications requiring them.
FDM environmental chambers come with a standard range from -40 to 180°, extendable down to -70°.
Standard humidity control is from 10 to 98%, but can also be extended according to the special testing requirements of our customers.
The 5°/min temperature heating rate of the FDM environmental chambers is ideal for standard altitude tests.
But what distinguishes us in the production of environmental chambers is customization: haven't you found the volume you are looking for, the standard to comply with, the right temperature range?
Our engineers will build for you and with you, an environmental chamber tailored to your requirements.
