DynoGuard® flange shields and maintenance systems
Protection against leaks, blow-outs and galvanic corrosion — quick repair solutions, preventive maintenance and LOTO systems for the entire industrial lifecycle.
A day of downtime costs more than prevention
Regular maintenance and blow-out protection are key to preventing premature equipment failure. DynoGuard® shields, Pow-R repair kits, flange-insulation kits and LOTO systems together provide a complete answer to planned and reactive maintenance challenges.
Fitted and removed in 30 seconds
DynoGuard® shields can be quickly removed and refitted, keeping fittings accessible at any time.
Prevented leaks and blow-outs
Pressure Diffusion Technology (PDT) localises leaks and prevents the formation of vapour clouds.
Reusable solution
Once a leak is fixed the shields can be reused — low lifetime cost.
Fits almost any surface
Protection against spray-out around flanges, valves, pumps and other equipment.
Pressure Diffusion Technology.
PDT uses a specially designed multi-layer stainless-steel mesh. The mesh lowers the pressure of the escaping medium so no dangerous vapour cloud forms — the leak is localised and shows up as controlled, easily detectable droplets.

Six variants, one for every medium
From entry-level PVC to the high-temperature, fire-resistant DrainMax — there is a suitable DynoGuard® shield for every industrial medium, temperature and pressure range.

DynoGuard® PVC
Entry-level, cost-effective PVC-coated PE fabric — for low-temperature chemicals and acids.

DynoGuard® PTFE
Glass-fibre + PTFE base with plastic reinforcement. For aggressive chemicals, acids, alkalis and oils.

DynoGuard® Clear
Transparent version for visual leak detection — quick diagnosis during maintenance.

DynoGuard® Steel
High-temperature, fire-resistant version with stainless steel components — for steam and hot media.

DynoGuard® DrainChem
Channels hazardous media: acids, alkalis, chemicals, cryogenic liquids — sealed with ePTFE tape.

DynoGuard® DrainMax
Maximum operating range with Slade® PyroTex® carbon-reinforced graphite tape — fire protection and drainage.
