ProRox® PS 978
ProRox PS 978 IN is a mandrel-wound stone wool insulation pipe section. The pipe sections are produced with an innovative water-repellent binder, known as WR-Tech™, to mitigate the risk of corrosion under insulation (CUI). WR-Tech ensures our stone wool maintains its superior water repellency even at elevated operating temperatures within the CUI range, while preserving its excellent thermal performance in use. Reinforced aluminium foil (ALU) facing is available upon request.

Product Description
ProRox PS 978 is a mandrel-wound stone wool insulation pipe section. The pipe sections are produced with an innovative water-repellent binder, known as WR-Tech™, to mitigate the risk of corrosion under insulation (CUI). WR-Tech ensures our stone wool maintains its superior water repellency even at elevated operating temperatures within the CUI range, while preserving its excellent thermal performance in use. Reinforced aluminium foil facing is available upon request.
The highly durable insulation sections come split and hinged for easy snap-on assembly and are especially suitable for the thermal and acoustic insulation of high-temperature industrial pipework subjected to mechanical loads.
- Water repellent to minimise the risk of CUI
- Resists water absorption to deliver long-term durability
- Non-combustible and fire resistant
- Pre-shaped for quick, easy and accurate installation and optimal performance
Product Benefits
- REDUCE THE RISK OF CUI Half of all hazardous events in industrial plants (such as pipe leakages or ruptures) are caused by aging mechanisms like erosion, corrosion and fatigue. So mitigating the effects of CUI improves the safety of people working in a plant.
- ENSURE CONTINUOUS PROCESS OPERATIONS Thermal conductivity of water is 25x that of air, so the thermal insulating effect of insulation material decreases when water gets in. 5 Vol-% of moisture decreases the thermal resistance of insulation by 25%.The optimal thermal resistance of dry insulation minimizes thermal losses and CO2 emissions and ensures a continuous production process.
- MINIMIZE TOTAL MAINTENANCE COSTS By using insulation that absorbs less water, you reduce the risk of CUI and unintended energy losses (which could lead to process stops). This significantly reduces total maintenance costs.
- Suitable for heavy duty applications which are exposed to high temperatures and high mechanical loads. Excellent fit provides optimal performance
- Easy to handle and to install
- Wide range of diameters and insulation thicknesses
- Suitable for use over stainless steel
- For temperatures up to 350°C, a support construction is not generally necessary
