Marine Duty Transformers

Overview

Acutran custom designs and manufactures a variety of dry-type custom transformers for the marine industry, including marine duty transformers, marine duty ISO boost transformers, and marine duty isolation transformers.

Acutran’s years of specialization in the transformer field has allowed us to develop a “MARINE DUTY CORROSITRAN” dry type transformer, which embodies heavy-duty industrial type construction along with a high degree of anti-corrosion protection, designed to add years of life to dry type transformers.

No matter how demanding your marine environment conditions are, or how tight your project timeline is, you can count on our extensive experience and array of design tools to create a custom solution for your marine applications.
