Cabin

The stainless steel cabin body, the inner and outer walls are made of 1.0 mm thick SUS304 stainless steel; the middle is made of high-density PU foam, which has good heat preservation effect.

Liner

The material of the inner tank is made of wide mirror 304 stainless steel, which is fully welded.

Door

The size of the gate is 3000×2200mm (W×H), single-opening and fully sealed, and the sealing adopts PTFE strip sealant (Teflon) (HBC1079 food-grade sealant). It has passed the EU ROHS environmental protection standard and passed the EU REACH chemical regulatory standard. Pass the US FDA food sanitation standards).

Sealing material

Use silicone rubber strips and glass sealant

Test process

1. Installation of UV air sterilizer to be tested:                                       Install the ultraviolet air sterilizer to be tested in the test aerosol room, connect the power supply and confirm that it can work normally. The test operation and the operation of the instrument and equipment are carried out outside the aerosol room through a window with a sealed sleeve or a remote control. The door cannot be opened until the end of the test.

2. Test environment condition setting:                                                      The temperature (20 °C~25 °C) and relative humidity (50~70) required by the test.

3. Aerosol spray contamination:

According to different aerosol sprayers set pressure, gas flow and spraying time to spray bacteria. While spraying the bacteria, stir with a fan (agitator). After spraying and contaminating the bacteria, continue to stir for 5 minutes and stand still for 5 minutes.
