Crankcase Ventilation for University New CHP Engine: CAT G3520H

The Equipment

Caterpillar G3520H


The Challenge

A power systems dealer on the east coast of the United States required a reliable closed Crankcase ventilation solution. A closed system is routed back to the low pressure side of the turbo, downstream of the air cleaner. This was for a new Combined Heat and Power (CHP) gas engine application for a large University expansion project.

The Solution

Solberg has developed the ACVB (Advanced Crankcase Ventilation with Blower) solution specifically for the Caterpillar G3500H series engines. Over the past 3-5 years, Solberg has partnered with a handful of authorized dealers across the globe to develop this solution. We have continuously upgraded and modified the offering to provide the most effective and efficient solution that is available today. With thousands of operating hours in the books, it was an easy selection process for this application. Once installed, Solberg visited the site to confirm a proper installation.


With a visit from Solberg to ensure the system was installed correctly, the unit performed well for initial engine testing and will protect the engine and surrounding environment for years to come.

The Product

The ACVB is designed to protect your engine’s turbo, coolers, and inlet air filters as well as help ensure environmental compliance while keeping engine rooms clean, safe and free of oil mist. The series comes standard with industry leading automated vacuum control technology to regulate crankcase pressure and prevent seal leakage. The replaceable filter element contains a proprietary media pack offering exceptional efficiency levels with an extremely long life, allowing operators up to one year before an element change is required.
