Halogenated ions, including chlorides, can attack the passivation layer of the stainless steel used in instruments and create pitting, rendering it susceptible to bacterial growth. Calcium, silica or dissolved metals can damage steam generators and create deposits or stains.
Elmatec has developed a processing chain, tried and tested in more than 70 clinics, hospitals and sterilization centers throughout France. This processing chain meets the requirements of standard NF EN 285 – Annex B: 2105, which has replaced standard NF EN 285+A2 since January 2019.
Starting with drinking water, under Ministerial Order of January 11, 2007 – Annex 1, our standard solution consists of:
Thus, we can deliver softened water (0°f and/or 5°f) for the pre-wash and wash phases to avoid scale deposits on the instruments. We also supply RO water with conductivity of less than 5 µS/cm at 20°C, a chloride concentration of less than 0.5 mg/l and hardness of less than 0.02 mmol/L, while preventing bacteriological risks for the rinsing, disinfection and steam generation phases.
The storage and distribution of the water must be controlled to prevent the risk of bacteria on instruments. Our reverse osmosis water loops are manufactured in accordance with recognized trade practices and use polyethersulfone (PES) 0.2 µm filters of proven quality for their antibacterial efficiency. We use a hydrophobic 0.2 µm filter vent cartridge on the RO tank. A maintenance service including regular disinfection of the treatment chain ensures that the quality of the water distributed is maintained.
The conventional treatment can be completed by:
The following data is required according to standard NF285 and your specific needs:
According to the recommendations DGS/5CDHOZ/EZ/2001/138 for the reduction of the risks of transmission of Non-Conventional Transmissible Agents (NCTA), we propose a treatment system consisting of deep filtration of sediments (10 µm and 1 µm) and sterilizing filtration (0.2 µm – pleated PES cartridges from the Memtrex range).
