Applications
Fixed water or foam stream applications covered by the selected monitor and nozzle combination. Coordinate flow, pressure, reaction loads and mounting with the project design.
Selection and project integration
Share the system drawings, protected hazard, equipment schedule and project specification with UDCT. Product selection should establish the required flow and pressure, pipework connections, materials, installation orientation and compatible components. Check the precise approval scope for the selected model, size and configuration against the current manufacturer documentation.
The product reference does not replace hydraulic calculations or the approved system design. For foam equipment, confirm the concentrate, proportioning range and discharge-device compatibility as one system. Use the manufacturer instructions for installation, commissioning and maintenance, and confirm the supplied configuration with UDCT before procurement.
