Case Studies

We help customers build safe, effective, and efficient systems. We pride ourselves on delivering the results our customers need in a wide variety of industries. 

To see solutions we have developed and deployed for others in the past, take a look at some of our case studies. From standby gen-sets to marine power installations to combined heat and power applications, Solberg has worked with them all.


Pre-Cleaner Filters Extend Service Intervals

The application used water-sealed liquid ring vacuum pumps to open packets while filling them with a sports drink powder. After switching to oil-sealed rotary vane pumps, the end user recognized the need for filtration to prevent the carryover of fine powder.

Liquid Separator Protects Vacuum Pump from Volatile Contamination

The customer carries out a vacuum drying process to remove moisture content from polymers. Due to the nature of the plastic materials, and the deep operating vacuum level, volatiles carried over to the screw vacuum technology, resulting in the requirement for regular pump maintenance. 

Reverse Pulse Filtration Technology for Vacuum Filling Lines

The customer’s end user used vacuum in their application process to keep packets open while filling them with porridge oats. They quickly discovered a need to install a filtration system due to fine powders entering the air stream and reaching their vacuum pump. They also wanted to increase maintenance intervals and requested a self-cleaning feature.

Leak Detection for Tank Fabrication

The customer was leak-checking large tanks that were fresh off of a welding line. Their objective was to connect the tank to the leak detector to ensure the weld integrity was up to their ISO standards and that there were no leaks. During the leak detection process, the tanks were pumped down, and some welding slag and manufacturing dust were pulled into the leak detector.

Solvent Recovery for Essential Oil Application

An essential oil producer was experiencing frequent oil changes and costly rebuilds with their rotary vane vacuum pump. As part of the extraction process, the pump pulls vacuum to remove solvents. Subsequently, they determined that ethanol was being pulled into the vacuum pump, causing the oil to degrade.

Renewable Natural Gas (RNG) - Primary Equipment - Moisture & Particulate Removal

A large Renewable Natural Gas producer in the U.S. required moisture and particulate removal for the primary treatment of thier biogas.  These filters are for the inlet of a compressor that has a gas stream of Methane, Nitrogen, Water, H2S, and CO2.    

Crankcase Ventilation for University New CHP Engine: CAT G3520H

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.

Crankcase Ventilation for Infirmary CHP Engine: CAT G3520H

A power systems dealer partnered with an infirmary to supply three gas engines for a CHP project. The existing crankcase breather systems were allowing bypass to contaminate the engine intake air filters and subsequently the internal engine components, the turbo charger and inter coolers. “This became quite serious when we found crystallized oil on the turbo blades which led to a costly overhaul.”

Crankcase Ventilation for Landfill Gas to Energy: Jenbacher Engines

A landfill gas to energy facility had ten enclosure mounted Jenbacher J420GS engines. The site was experiencing inter-cooler issues and other engine challenges. The existing crankcase ventilation filter routed the crankcase blow-by back into the turbo where bypass and carryover were being seen. They wanted to eliminate and isolate the crankcase ventilation system and vent to atmosphere.

Crankcase Ventilation for Natural Gas Engines: Cummins QSK60 & QSV91

On a handful of Cummins engines, the crankcase ventilation systems were under-performing, even failing. They tried many different styles and types of closed crankcase systems with no success. These systems had minimal element life and high crankcase pressures. Low-efficiency elements did not provide the needed protection for the turbo and aftercoolers, therefore, service costs were increasing.
