The structure is solid, the installation is convenient and quick, and the construction period is short. |
| Vertical boards and roof boards | Made of SUS#304 matte stainless steel (full thickness 1.0mm) |
| Bottom material | Made of SUS#304 embossed stainless steel anti-slip material |
Chamber door | The exterior of the door is made of cold-rolled steel plates that are CNC cut, folded, and painted (thickness 1.2mm), and the interior is reinforced with square tubes to ensure no deformation or air leakage during long-term use. Hinged single door, in order to prevent condensation or frost on the door frame and the edge of the door during low temperature testing, the door frame and the edge of the door are equipped with electric defrosting devices. |
| Bottom | The bottom drainage groove is 60mm wide and 30mm deep. It is sunken around the bottom perimeter. 2 stainless steel floor drains are used for the test chamber to test high temperature and high humidity to discharge condensation water. |
Bottom plate | (a) Uniform load: 500kg/m2; (b) The bottom plate bearing capacity is ensured by horizontal channel steel to ensure that the test chamber is installed on a flat surface. The test chamber bottom plate is installed with load-bearing wooden squares. A 3mm anti-slip aluminum plate is installed on the stainless steel bottom plate to ensure uniform stress on the entire bottom plate. |
Observation window | Observation window size: Width 400*Height 600mm. The door is equipped with a heat-resistant and anti-sweat 3-layer vacuum large glass observation window. During any test, there will be no frost or condensation on the surface.
|
| Lighting device | 2 lighting lamps are installed in the test chamber, which is explosion-proof and moisture-proof. |
Lead hole | The body is equipped with 1 Φ100mm hole, 1 soft plug and 1 hole cover, which can be used for external test power cord or signal line passing through
|
| Sealing | The door seal of the test chamber is made of silicone rubber strip, which is resistant to high and low temperatures, anti-aging, and has good sealing performance. |
| Pressure balance window | The pressure balance window balances the pressure inside and outside the warehouse. It prevents the door from being pushed outward when the internal pressure is too high during heating, and prevents the door from being sucked inward and unable to open during cooling. It is normally closed, and opens automatically when the pressure difference is large. |
