PTI-38 Airflow

The PTI-38SI Enclosed 38 kW Diesel Generator features a specially engineered airflow system designed to maintain optimal cooling within its sound-attenuated enclosure. Fresh air is drawn into the unit, directed strategically around vital components, and efficiently expelled through the radiator. This controlled airflow pathway helps regulate internal temperatures, minimizes heat buildup, and ensures reliable performance, even in demanding mobile or enclosed environments.
