Relisafe ™ HPSF
High-pressure boiler feedwater often carries abrasive suspended matter that can easily blind or irreversibly damage expensive online water chemistry analysers. The Relisafe™ HPSF (High Pressure Sample Filter) acts as a defensive barrier for your instruments. Built to withstand blistering pressures of up to 350 Kg/Cm², this unit utilises a heavy-duty SS316 housing that guarantees absolute structural integrity.
Moving away from cumbersome legacy filter designs, the HPSF is built completely around user experience. To clean the 40-micron element, an operator can simply unscrew the prominently designed hexagonal cap, flush the mesh, and replace it in seconds. Crucially, it manages this high-level filtration without starving your downstream analysers, maintaining a negligible pressure difference of less than 2 Kg/Cm² across the entire unit.
Applications of Relisafe™ HPSF:
First-stage particulate filtration in supercritical boiler water sampling, high-pressure SWAS racks, and any heavily pressurized industrial line requiring 40-micron protection prior to analytical sensing.
- Extreme Pressure Rating: Built specifically for demanding boiler applications, safely handling design pressures up to 350 Kg/Cm²
- Rapid, Tool-Free Maintenance: An ergonomic hex cap provides a superior grip, completely streamlining the process to remove, clean, and replace the filter element
- Premium Protection: Consistently filters out damaging particles sized up to 40 microns, extending the life of your downstream sensors
- Unrestricted Analyser Flow: Designed for maximum throughput (up to 100 LPH) while keeping the pressure drop below 2 Kg/Cm²
