4. Chamber construction
|4.1 Construction type||
Integral box structure
The test box consists of three parts: the main insulation box, the air conditioning system, and the electrical control cabinet.
|4.2 Thermal insulation structure||Outer box color steel plate - intermediate insulation layer is temperature resistant foam insulation material - inner box SUS304 stainless steel|
|4.3 Outer box material||Outer box color steel plate|
|4.4 Wall material||SUS304matte stainless steel plate,Thickness=1.0 mm；Inner box full welding|
|4.5 Insulation||Rigid polyurethane foam insulation layer,Thickness=100mm, flame retardant grade B2.|
Single door, left open,；Explosion-proof handle
Two silicone rubber sealing strips and anti-condensation electric heating device at he door frames to prevent condensation at low temperatures；
|4.7 Observation window||
Observation window on the door(size:W210*H270MM)
Multi-layer vacuum glass window with electronic film for heat and sweat defogging protection.
Glass enclosed stainless steel protective net, to prevent the explosion when flying glass (can not guarantee absolute safety).
|4.8 Explosion-protected chains||
Two explosion-protected chains are added on both sides of the box door. The chain is longer. When the box is opened, it can be opened a bit, letting Quick release of internal air pressure, but no pop.

Q1 : Can you customize the product?
A: Yes, we can customize any products according to requirements.
Q2 : How to choose the most suitable products?
A: Our professional team will give you the best suggestion,just be patiently to tell us the information about
the parameters your required.
Q3 : Can you arrange installations and commissioning in our lab?
A: Firstly, for standard chamber we had 3-5 days commissioning before shipping , you just need link
power in your lab, then can start to operate;
Secondly; we had detailed operation manual with chamber , any problems you can find and solve in it;
Thirdly, some of customized chambers we should to install and teach your team to operate.
We use PP Film wrapping the test chamber to protect the test chamber from moisture or being scratched
first, then use strong plywood case for easyload and transport, and to keep the chambers from potential
crash or impact.
If you face any problems in future during testing process we promise we will give you a reply within 48
hours and solution provide within 3 working days. We can offer operation video and English operation
muanual. We can provide video-conference. If customers require on-site service, the transport and travel
expense shall be borne by customer.
