Cat 3306 DES upgrade

Ventico 3306 DES Engine Package – Paper Filter Configuration

Built on 30 Years of Underground Performance

The Ventico 3306 Explosion-Protected Diesel Engine System (DES) with paper filter configuration is the result of over 30 years of industry experience, development, and in-field refinement. Built on the globally trusted Caterpillar 3306 mechanical platform, this engine package delivers reliable, serviceable power tailored to the demands of underground coal mining.

Fitted with high-efficiency disposable paper exhaust filters, this configuration offers a familiar, cost-effective solution for diesel particulate matter (DPM) control, compliant with MDG 43 and AS 3584.2 when maintained on schedule. Its mechanical simplicity and low running cost make it a staple in underground machine rebuilds and fleet standardisation.

For enhanced safety and compliance monitoring, the package includes Ventico’s SEMS engine management system, which features:

  • IECEx-certified electronic shutdown control

  • Automatic fault/event logging for diagnostics and compliance traceability

  • Automatic secondary CO₂ shutdown system – ensuring added protection during critical fault conditions

The 3306 DES is ideal for load haul dump units, graders, and service vehicles, providing trusted performance with integrated safety and regulatory compliance.
