Conventional open-ventilated alternators rely on airflow for cooling. In contamination-heavy operating environments, that same airflow can introduce fine particles, abrasive dust, moisture and debris into the alternator.
Over time, these contaminants accumulate around insulation systems and electrical components, contributing to accelerated wear, insulation degradation and unplanned downtime.
The T-Type Totally Enclosed alternator addresses this challenge at the design stage.
Featuring a totally enclosed brushless synchronous construction, the T-Type platform physically isolates active electrical components from the external operating environment, preventing particulate ingress and direct contamination exposure.
Standard IP54 is designed for demanding dust-heavy environments and routine exposure to moisture, while optional IP67 configurations provide enhanced protection for applications exposed to severe water ingress or temporary water immersion.
Unlike severe-environment open-ventilated machines designed primarily around humidity, salinity or corrosive exposure, the T-Type platform is optimised specifically for environments where physical contamination and ingress are the dominant operational threats.
The T-Type range is available in both 2-pole and 4-pole configurations from 6.5 kVA to 96 kVA at 50Hz, supporting a broad range of heavy-duty mobile and industrial power generation requirements.
Applications include:
The T-Type platform is particularly suited to applications where physical contamination, particulate ingress or increased exposure to moisture create greater reliability risks for conventional open-ventilated machines.
Environmental challenges vary significantly by application. Quarries and construction sites deal primarily with dust ingress, cement particles, incidental spray, and physical debris. Coastal installations and industrial plants face different problems – persistent humidity, salt spray, chemical vapours, and cumulative moisture exposure. Where physical contamination and washdown exposure dominate, the T-Type provides physical isolation through totally enclosed construction. For applications where humidity, salinity and corrosive exposure are primary concerns, the V-Type severe-environment open-ventilated platform offers enhanced environmental durability whilst maintaining thermal efficiency.
