Product overview
SIEX-HC 227 S-FLOW is a SIEX total-flooding suppression system using HFC-227ea (FM-200). The agent and distribution network are selected together for the enclosure and the protected equipment. The system provides a clean extinguishing medium for applications where residue cleanup is an important selection factor. Its S-FLOW valve broadens the available working-pressure choices and supports layouts with hazards farther from storage, subject to the hydraulic calculation.

Selection and project integration
Share the protected-space drawings, hazard description, equipment schedule and project specification with UDCT. The technical review should establish the selected system configuration, required quantity, installation constraints and interfaces with the detection and control equipment. For gaseous suppression, enclosure integrity, pressure relief, discharge acoustics and personnel safeguards must be assessed as part of the engineered design.
The published model designation is a product reference, not a final bill of materials. Agent quantities, pipe sizing, nozzle selection, storage arrangements and release logic depend on the approved design. Use the current manufacturer instructions for installation, testing and maintenance, and confirm availability with UDCT before procurement.
