Structural Features
The inner wall of the chamber is made of high nickel SUS#304 stainless steel and degaussed, the thickness of the plate is 3.0mm.;
JOEO walk in environmental chamber outer wall is made of 10 mm thick hrs steel plate, and the detachable plate structure is adopted at the proper position to facilitate the maintenance and repair of the insulation interlayer of the chamber in the future;
Load capacity of laboratory floor: 800kg/m^2(uniform load) ;
The chamber door is equipped with two silicone rubber sealing strips to ensure the best sealing performance of the walk in stability chamber and to ensure long-term use without cracking and deformation.
Refrigeration System
Compressors equipped with world famous brand such as Tecumseh (France made), Bitzer or GEA BOCK (Germany made).
It applies Denmark DANFOSS and Japanese SAGLNOMIYA solenoid valves to improve the overall reliability of the environmentally controlled room.
MP10 module has motor over-heating protection (with LED indicator), exhaust temperature over-heating protection (requires optional temperature monitoring probe and LED indicator), power indicator, alarm function.
Electrical System
The overall layout of the circuit cabinet looks very neat and professional. JOEO walk in environmental chamber circuits are arranged in accordance with UK standards and are equipped with complete circuit diagrams. Each line has a unique code which is clearly defined and easy to locate for troubleshooting.
We use electrical components of world famous brands, such as Schneider from France,Carlo Gavazzi from Switzerland,Mitsubishi from Japan,Rainbow from Korea.
