Airflow of Diesel Enclosed Generator

PTI-20ENC Airflow

The PowerTech PTI-20ENC quiet enclosed 20 kW diesel generator is built with an advanced airflow system that delivers reliable performance, even in hot and demanding conditions. Air is pulled in through the base pan, filtered, and directed through the engine compartment to cool critical components. It’s then pushed out through the radiator side, effectively removing heat and protecting sensitive parts from overheating. This smart airflow design helps maintain consistent operation under load and is a signature feature of PowerTech generators, offering superior cooling efficiency and durability for mobile power applications in high-temperature environments.
