Reinraumtechnik Nitto Kohki

Nitto Kohki cleanroom couplings are engineered for contamination-critical pneumatic circuits in semiconductor fabrication and precision assembly environments. The Semicon SCT and Semicon SP Cupla series feature zero-spill valve technology with residual fluid loss below 0.01 ml per connection cycle, particle-generating surfaces rated to ISO 14644-1 Class 1 cleanroom compatibility, and body materials including PVDF and stainless steel 316L that withstand aggressive process gases and cleaning agents. Operating pressures range from 0 to 0.9 MPa with flow coefficients (Cv) optimised for low-pressure pneumatic tool circuits common in wafer-handling and chip-bonding lines.

As a specialist distributor for Nitto Kohki pneumatic components, esd.equipment stocks 92 cleanroom-certified coupling products across the SCT and SP Cupla families, all compliant with IEC 61340-5-1 electrostatic discharge requirements applicable to EPA-controlled semiconductor environments and traceable to ISO 14644 cleanroom standards.

Typical application areas: Semiconductor wafer fabrication and chip bonding (ISO 14644-1, SEMI S2), precision electronics assembly in EPA-controlled environments (IEC 61340-5-1), medical device manufacturing requiring contamination-free pneumatic circuits (ISO 13485), flat-panel display production, optical component assembly, and aerospace precision manufacturing (AS9100).
