--------------------------

 **The innovative two-in-one AIRPURION STERILE FRIDGE active system is the only system that combines safe UV disinfection and odor elimination in cold rooms:**

- **Disinfection of the air by UVC light - state of the art disinfection technology**
- **Odor elimination by PHOTOCATALYTIC OXIDATION through titanium dioxide surfaces activated by UVA light.**

   ![STERIL_FRIDGE_active](https://www.purion.de/fileadmin/_processed_/9/c/csm_STERIL_FRIDGE_active__3bea2efed8.jpg) The AIRPURION STERILE FRIDGE System:

- extends the shelf life of stored food
- operates entirely without chemicals
- meets the highest HACCP requirements as the only system with special shatter protection through UV-transmissive coating (no mercury release in case of lamp breakage)
- allows continuous operation as it is a closed system with active air intake
- various options to monitor disinfection performance
- virtually maintenance-free

| Disinfection rate of 88% for room volume up to 50m³ |
|---|
| Shatterproof protection for the lamps |
| Fault indication lamp |
| UV lamp lifetime monitoring - Operating time counter (OTC) |
| Stainless steel housing |
| Photocatalytic surfaces |
| UVC lamp for disinfection |
| UVA lamp for activating the titanium dioxide surface |
| Operating temperature at least -25°C |
| 340mm wide x 450mm deep x 125mm high |
| For ceiling mounting |

 ####  THE INNOVATIVE AIRPURION STERILE FRIDGE ACTIVE TWO-IN-ONE APPROACH:

 **1st stage: sustainable UVC disinfection**
Active air circulation by fan and air disinfection by UVC light (260 nm wavelength) in the first chamber.

- Short-wave UVC radiation has a strong germicidal effect. UVC uses the photolytic effect for this, whereby the microorganisms are destroyed or inactivated by radiation, which prevents them from multiplying further.
- When disinfecting, these effects occur at wavelengths below 320 nm, with the optimum at approx. 260 nm.
- UVC radiation is the only verifiable chemical-free disinfection technology - used by hospitals and research institutions

**Result:**

- Sustainable air disinfection
- Elimination of bacteria and viruses

 **2nd stage: Photocatalytic oxidation**

Disinfected air is fed into the 2nd chamber and the air is treated with photocatalytic oxidation using UVA light

- Special UVA light activates titanium dioxide surface
- This creates highly reactive hydroxyl radicals
- These highly reactive radicals attach themselves to volatile carbon compounds - the main source of odor pollution.
- This breaks down the volatile carbon compounds into harmless components such as carbon dioxide and water and eliminates the odor pollution

**Result:**

- Elimination of volatile carbon compounds
- Elimination of odors
