Grit-Free Surface Preparation Below the Waterline
Engineered for underwater environments, diving operations, and offshore maintenance, delivering controlled surface conditioning even in demanding subsea conditions.
Below the surface
When corrosion protection needs to extend below the surface of the sea, precision, safety, and reliability become even more critical.
“Grit-free preparation, controlled even below the waterline.”
Water pressure
Managing buoyancy and pressure effects at depth.
Limited visibility
Operating in murky or restricted subsea environments.
Environmental risk
Preventing contamination in sensitive marine ecosystems.
Operational constraints
Meeting strict diving campaign and ROV requirements.
Hydraulic power, underwater integrity
The Bristle Blaster® Subsea is a hydraulic underwater device with a unique water drive. Connected via a single, neutrally buoyant high-pressure hose, it creates a controlled, inspectable surface profile below the waterline, without grit or containment. Topside, the same principle runs on the Bristle Blaster® range.

Spark-free surface prep for subsea and splash-zone hot-work zones.
The Bristle Blaster® Pneumatic Ultimate has undergone an independent Gexcon ignition-hazard analysis and ATEX 2014/34/EU conformity evaluation, so coating repair can continue in hazardous offshore areas without electric-tool hot-work permits.
Categorie 2, zone 1 gas & zone 21 stof
Zone 1 explosief gas, beoordeeld voor gasgroep IIA (benzine, hexaan, propaan), EPL Gb.
Zone 21 explosief stof, beoordeeld voor stofsubgroep IIIC, EPL Db.
Volledig pneumatisch, persluchtaandrijving, geen elektrische componenten, geen elektrische ontstekingsbron.
Onafhankelijk beoordeeld door Gexcon volgens de geharmoniseerde EN ISO 80079-reeks.
Bristle Blaster® Pneumatic Ultimate
De bundelontladingstest registreerde geen meetbare ontlading, geslaagd voor gasgroepen IIA, IIB en IIC.
Acht vallen bij omgevings- en vriestemperatuur, geen schade die de ontstekingsveiligheid van het gereedschap vermindert.
Gebruikt in explosieve propaan-luchtatmosferen (groep IIA) zonder waargenomen ontsteking.
De getoonde markeringen weerspiegelen de reikwijdte van de onafhankelijke ATEX-conformiteitsbeoordeling. Bevestig de gecertificeerde markering op het typeplaatje van het gereedschap en de conformiteitsverklaring voor jouw specifieke configuratie vóór het voorschrijven.
IMCA, DNV & ISO aligned
MontiPower subsea tools are configured in accordance with offshore safety standards and industry diving protocols. IMCA-compliant, built to DNV offshore requirements, and compliant with relevant ISO standards.
