SC 340 – Troubleshooting Oil Systems
SC 340 teaches technicians how to troubleshoot oil system problems methodically rather than reactively. The course focuses on understanding where oil goes, why it moves, and what system conditions allow oil to escape or overheat.
This course is intended for:
- Industrial refrigeration service technicians
- Compressor mechanics and startup technicians
- Engineers supporting field troubleshooting
- Operators monitoring oil levels, temperatures, and alarms
Participants learn how to separate symptoms from root causes and apply a repeatable troubleshooting process to oil‑related issues. The course emphasizes real‑world failures such as rapid oil loss, unexplained oil disappearance, coalescer problems, economizer back‑feeding, and oil cooling system misoperation.
Course Sections
-
General Troubleshooting
Building a disciplined, bias‑aware troubleshooting approach. -
Rapid Loss of Oil
Diagnosing sudden oil disappearance and active escape paths. -
Gradual Oil Loss
Differentiating normal oil consumption from system problems. -
Oil Temperature Troubleshooting
Resolving oil cooling, injection, and temperature control issues.
Outcome:
After completing SC 340, technicians can confidently diagnose oil problems, avoid unnecessary oil additions, prevent compressor damage, and resolve issues at their true root cause instead of treating symptoms.

This course is designed for:
- Industrial refrigeration technicians and mechanics
- Operators responsible for compressor control and efficiency
- Engineers supporting system design or optimization
- Anyone working with screw compressors and economized systems

SC 210 – Compressor Oil Systems
SC 210 provides a detailed, technician‑level understanding of oil systems used in oil‑flooded screw compressors. The course focuses on how oil supports compressor reliability, efficiency, and capacity control—and what happens when oil systems are misunderstood or misapplied.
This course is intended for:
- Industrial refrigeration technicians and mechanics
- Operators responsible for compressor reliability
- Engineers supporting system troubleshooting and optimization
- Anyone working with oil‑flooded screw compressors
Students learn how oil performs far more than lubrication. The course explains oil’s role in sealing compression chambers, cooling the compressor, powering hydraulic systems, balancing axial loads, and protecting critical bearings.
Course Sections

The Oil Cycle
How oil is separated, cooled, filtered, distributed, and returned. -
Oil Cooling
External cooling methods and liquid injection oil cooling control. -
Oil Filtration
Filter ratings, particle sizes, and bearing life relationships. -
Oil Distribution
Oil flow paths and proper oil injection valve setup. -
Oil Separation
Separator operation, velocity effects, and head pressure challenges. -
Oil Pumps
When pumps are needed and the true cost of running them. -
Hydraulics
How oil power is used to move mechanical components. -
Slide Valve Hydraulics
Capacity and Vi control using oil and suction pressure. -
The Balance Piston
Managing axial gas forces and protecting thrust bearings.
Outcome:
