There are many types of testing room, but they are high and low temperature limits. Let's look at a typical temperature threshold, and why they exist.
The test chamber is usually made of a material called leaf heater wires. By wire heater, a greater amount of heat that is generated by a continuous loop. The result looks like a toaster baked inside. Near a heater fan circulating air, so that the sample chamber is not exposed to heat radiation. It is very easy to add high limit heater and improve the speed and / or the chamber.
Linpin test chambers are typically below 180 ℃. High temperature limit below which is why there is a limit temperature chamber fault:
In the limit of 85 ℃: the puzzle of our walk-in chambers cannot go more than 85 of these units used to expand polyurethane insulation. Polyurethane can begin to reduce the temperature to over 85 ° C. For people who need high temperature walk-in customers, we switched to fiberglass insulation. Fixed user can switch to another mode. Since the glass fiber insulation material is not rigid, we need to override the angle planes, so we call these models or in a solid structure.
150 ℃: There are two reasons, we limit 150 ℃. First chamber, there may be restrictions in the interior of the material. Second, the room very quickly, we can limit the temperature in order to avoid accidental launch problem overheat protection device.
170-180 ° C: stop temperature most of the models in this regard. There in the cooling coil cooling danger of burning oil.
210 ° C: separation due to thermal shock chamber cold hands, do not worry about refrigerating machine oil. However, the limit temperature of about 200 ℃ several structures close to the chamber in which the material used.
300 ℃: significant changes in the structure of the chamber and the material allows higher temperatures. In this case, the cooling coil from the damper isolation chamber, so that it is exposed only when necessary. This will be strictly Chamber of customization.
