Crankcase Ventilation for CHP Engines G3512E

The Challenge

A power systems dealer was looking for a reliable closed crankcase solution.  This was a new installation for three Caterpillar G3512E natural gas engines in the Mid-West United States.  These engines were to be used in a CHP application.

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.

The Solution

Solberg scheduled multiple on-site visits to review installation details and provide installation location recommendations. Solberg provided its ACV Series Advanced Crankcase Ventilation System.   This includes Solberg’s vacuum  regulation technology. The Solberg vacuum regulation valve maintains a precise range of vacuum that is best in the industry. This ensures the vacuum levels are at an acceptable range per  the OEM’s specifications.  After calculating the crankcase blow-by and drawing on field tests, one unit would be required per engine.  Solberg provided a specific kit that included digital gauges.

Results

With constant communication throughout the entire project, the three Solberg ACV units were successfully installed. They are currently running without any challenges. The high efficiency coalescing filter successfully captured the oil mist and drained it back to a Solberg waste oil console.  The ACVs were run in the closed configuration and provided the clean, filtered, crankcase blow-by back to the intake manifold along with a consistent level of vacuum in the crankcase.

The Product

The ACV 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 & 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.
