COOL-FIT 4.0 Adaptor fitting PE/iFIT

  Datasheet (PDF)

The Georg Fischer COOL-FIT 4.0 adaptor fitting PE/iFIT d32mm (code 738 943 108) provides a factory pre-insulated, vapor-tight transition interface between the COOL-FIT 4.0 PE100 piping network and modular iFIT installation lines. Engineered for industrial refrigeration, secondary cooling circuits, HVAC installations, and process cooling applications in the food and beverage industry, this transition component enables seamless mechanical bridging from secondary chilled distribution mains to modular terminal systems, fan coil units, or cooling manifolds. The media-bearing assembly integrates a metric PE100 SDR11 spigot end with a free length L1 of 36 mm for electrofusion jointing via standard COOL-FIT couplers, paired with a precision transition module fabricated from premium stainless steel 1.4404 (316L) to ensure exceptional mechanical strength and corrosion resistance. Sized at DN25 with an outer media pipe diameter d of 32 mm and an iFIT interface d1 of 25/32 mm, the fitting operates reliably at a nominal pressure rating of 10 bar across an operating medium temperature range of -50 degrees C to +60 degrees C. The fitting includes factory-engineered insulation half shells featuring high-efficiency closed-cell foam protected by an impact-resistant, weather-proof black outer casing with an overall outer diameter D of 103 mm, a transition collar diameter D1 of 90 mm, an insulation length L2 of 80 mm, and a total fitting length L of 132 mm. This insulated envelope maintains full vapor sealing and thermal continuity across the connection boundary, preventing atmospheric moisture ingress, condensation dripping, and energy loss without requiring cumbersome on-site post-insulation. Designed for integration with a separate iFIT adapter, the component establishes a robust, maintenance-free connection that safeguards plant performance over a 25-year service life.
