Overview

ARCO Marine Zeus A225S Vortec Alternator with Regulator, manufacturer part number 4018.

Zeus A225S Vortec Alternator with Regulator

The highest power output alternator in its size/class.

Features:

  • Engineered for High Energy Production.
  • Suitable for Marine, RV, Military, and Commercial applications.
  • Rapidly charges large battery banks.
  • Coolest operating temperatures for increased performance. Runs 8 - 20% cooler than incumbent alternators due to:
  • Heat shedding coatings
  • Rectifier located on housing exterior
  • Dual cooling fans
  • OEM Components
  • Optimized for performance at idle speeds.
  • Reduces the need for a generator by creating additional power with your engine.
  • Unleash peak performance with E-Coat/Cerakote. Our advanced coating absorbs less heat, keeping the A225S cooler. This translates to more amperage for sustained periods.
