Ultra violet rays emitted at 254 nm generally known as UVc are capable of destroying living micro organisms and notably bacteria, viruses, fungi and algae. UVc rays act directly on organisms' DNA. |

• A system that avoids the use of chemical products:
- it is therefore ecological and has no impact on the environment
- it does not create harmful sub-products
- it enables compliance with the European Directives related to the use of biocides
• A physical active agent:
- it does not modify the treated fluid's physico-chemical balance
- there is no risk of excess dosage
- no sub-products are formed
• It may be used in combination with other types of treatment without any constraints:
- filtration
- softening and demineralisation
- inverse osmosis
- biological treatment
- combination of H2O2/UV and ozone/UV.
• Investment and maintenance costs are low:
- easy installation
- maintenance is limited to cleaning and UVc ray lamp replacement

The advantages of our sterilizers
|
| |
|
Our UV sterilisers are designed and produced using state of the art teschnologies:
- Computer Aided Design and Manufacture
- Laser cutting
- Soldering under a controlled atmosphere
|
|
|
|
| |
|
High quality finish and reassuring reliability:
- Mirror polished reactors
- Industrial quality electrical units
- Exclusive use of mono-base, high yield lamps
- Ballast is electronic without starter and do not heat
- All components are of the highest quality and tested
|
|
|
|
| |
|
Installation is fast and easy:
- Our reactors are of vertical design
- Compact size
- Reactors and electrical units are delivered pre-wired
- An upper purge cap enables air removal when placed in the water
|
|
|
|
| |
|
|
Maintenance has been made simple:
- The reactors are designed to enable 100% emptying
- Lamps can be changed without stopping the water flow
- An exclusive proofing system prevents any risk of breaking the quartz tube or of leaks
