Health-Compliant Shower Head Production
This project involved developing a shower head with integrated anti-limescale features that meets Attestation de Conformite Sanitaire (ACS) requirements for drinking water contact in France and Belgium. The design combines polycarbonate and silicone materials to prevent calcium buildup while maintaining optimal water flow.
Anti-Limescale Design
Flexible silicone nozzles allow users to simply wipe away limescale deposits with a finger. The internal water channels feature smooth, non-stick surfaces moulded with controlled surface roughness (Ra <0.4µm) to minimise mineral adhesion. Water chemistry testing confirms 60% less limescale accumulation versus standard ABS designs.
ACS Sanitary Compliance
All water-contact materials (PC body, LSR nozzles, EPDM seals) undergo ACS certification testing: migration testing for metals, TOC (Total Organic Carbon), and organoleptic assessment. Full documentation provided for building code compliance in France and Belgium.
Manufacturing
The shower head body is injection moulded in Makrolon polycarbonate. Silicone nozzles are LSR-moulded separately and press-fitted. Final assembly includes the flow regulator, filter screen, and connector fitting. 100% flow rate and leak testing at the end of the line.
Quality Assurance
ISO 9001:2015 certified. Pressure cycle testing (10,000 cycles at 10 bar), thermal shock testing (5°C to 65°C, 500 cycles), and UV ageing (2,000 hours) validate long-term performance.
Frequently Asked Questions
What water-saving features are available?
Integrated flow regulators limit flow to 6, 8, or 10 litres/minute (vs 12-15 L/min standard). Aerator technology maintains perceived flow volume while reducing actual consumption by 40%.
Is the design compatible with standard shower connections?
Yes, standard 1/2" BSP male thread fits all European shower hoses. Adapter for 3/4" connection available.
