ELECTRIC AC HYDRAULIC POWER UNIT

We specialize in the design and manufacture of electric 3 phase AC ATEX-rated hydraulic power units, meticulously engineered for safe, efficient, and reliable operation in hazardous environments where explosive gases or dust are present.

What is an ATEX-Rated Hydraulic Power Unit?

An ATEX-rated hydraulic power unit meets strict European directives (ATEX 2014/34/EU) for operation in potentially explosive atmospheres, such as chemical plants, oil & gas installations, and offshore platforms. These units utilize explosion-proof motors, electrical controls, and construction materials that eliminate ignition risks, ensuring maximum safety and regulatory compliance.

Key Features of Electric 3 Phase AC ATEX Hydraulic Power Units

  • Explosion-Proof Electric Motor
    • Heavy-duty, 3 phase AC motors (typically 380-480V, 50/60Hz) with ATEX flameproof enclosures (e.g., Ex d IIB T4 or T5).
    • Motors available in a wide output range (e.g., 2.2kW to 50+kW) for high power applications.
  • Robust Construction
    • All wiring, starters (such as star-delta or direct-on-line), and junction boxes are ATEX certified and IP55+/NEMA 4X rated for weather and dust resistance.
    • Enclosures, frames, and couplings designed for severe environments, often including stainless steel options and anti-corrosive coatings.
  • Advanced Hydraulic Components
    • High-efficiency axial piston or gear pumps, sized for optimal flow (often 7–247L/min) and pressure (up to 300–320bar).
    • Pressure, return, and drain line filtration (to 3 microns) for oil cleanliness and system longevity.
  • Integrated Safety & Control
    • Control panels with basic-to-advanced functionality, all in flameproof housings.
    • Low-level oil and high-temperature trip switches for automatic shutdown and fault protection.
    • All skid wiring, earthing, and bonding completed to meet ATEX standards.
  • Thermal Management
    • Integrated hydraulic oil coolers (e.g., seawater heat exchangers, air-blast) to maintain operating temperature in continuous-duty situations.
  • Comprehensive Certification
    • Supplied with full ATEX documentation, as well as DNV, ABS, CE, or other certifications as project requirements demand.

Typical Manufacturing Process

  1. Design & Engineering
    • ATEX-certified design process with CAD modeling, electrical circuit planning, and zone analysis.
    • Custom tank sizing, flow, pressure, and interface requirements determined with the client.
  2. Material Selection
    • ATEX-rated motors, switches, connectors, and armored cabling sourced from accredited suppliers.
    • Heavy-gauge steel or stainless for reservoir and frame construction.
  3. Precision Fabrication
    • CNC laser cutting, welding, and skilled assembly to ensure robust fit and finish.
    • Components such as sacrificial weld-plates or lift points included per handling and marine standards.
  4. Component Integration
    • Pumps, filters, cooler, reservoir, valving, gauges, and safety devices installed and plumbed.
    • Comprehensive internal and external wiring fully compliant with ATEX and electrical codes.
  5. Rigorous Testing
    • Thorough hydraulic, functional, and electrical tests—including pressure, filtration, leak, and automation cycles.
    • Third-party or customer-witnessed tests as specified for hazardous-site equipment.
  6. Documentation & Certification
    • Delivery of complete manuals, test docs, and ATEX compliance package for traceability.
