| Inlet Guide Vane Assemblies |
| |
| Enhance Your Compressor Efficiency and Reliability While Increasing Your Energy Savings |
Why Install Air Relief Inlet Guide Vane |
 |
- Tighter, more exacting control
- Competitively priced
- Thin line style (2” wide instead of 12” to 24” wide)
- Pre-swirl to the inlet flow reduces horsepower and increases energy savings
- Save even more energy with Load Sharing and IGV’s
- Gear-driven instead of linkage-drive for a smoother control and lowered maintenance
- Internals are factory-lubed and sealed to prevent entry of debris
- Stainless steel vanes virtually eliminate corrosion
- Return on investment can be less than 1 year, based on energy savings

| Cenlube Synthetic Lubricant for Centrifugal Compressors |
| |
 |
- Anti-wear properties
- Extended oil change intervals
- Less downtime for maintenance
- Reduced waste oil disposal costs
- Wide operating temperature range and high viscosity index
- Gearboxes can run cooler due to reduced friction
- Increased thermal and oxidative stability over petroleum oils
- Eliminates or reduces varnish on critical component surfaces

By performing an overhaul on your centrifugal air compressor now, you can dramatically reduce the chances of a more costly overhaul later....
Catastrophic failures are almost always a result of a rotating impeller coming into violent contact with a stationary diffuser or inlet. This type of failure can result in extensive gearing damage and also create a domino effect of damage for the unit’s internal components. The cost of performing a preventative overhaul is comparable to the cost of gear replacement alone, if a catastrophic failure occurs. Basic Workscope:
• Clean, test and inspect air coolers for each stage
• Clean and balance rotor assemblies for each stage
• Clean and inspect diffusers for each stage
• Clean and inspect moisture separators for each stage
• Bullgear shaft seal
• Bullgear bearing set
• Thrust bearings for each stage
• Plain bearings for each stage
• Air and oil seals for each stage
• Gasket kit
• 1 year warranty

| Remanufactured Centrifugal Air Compressors / Airends |
 |
| |
| Remanufacturing is not just simply ‘fixing’ or ‘repairing’. Remanufacturing requires that the product be indistinguishable from the new product in performance (capacity and efficiency). |
| |
Provide us with the required flow (cfm), discharge pressure (psig), elevation, inlet and water temperatures. Then our engineers aerodynamically design a customized fit for your application. When the compressor design is completed a competitively priced quote will be sent to you.

| Stainless Steel Sleeving |
| |
Sleeving deteriorated cooler and diffuser bores is a final, permanent solution to the chronic problem of erosion, scaling, and rust in the critical locations. Stainless steel sleeving will last the lifetime of your compressor.
If the condition of a cooler bore, cooler barrel, or diffuser bore is deteriorating, it may be recommended that it be sleeved. Sleeving is the process of removing existing, deteriorated material in a casing or barrel with a machining process and replacing it with a high quality stainless steel sleeve.
When you have eroded cast iron bores, the sediment and build-up will fill any voids in the bore, in effect, "welding" the cooler in place. A large percentage of the time, during disassembly, this results in an unsalvageable air cooler that could otherwise be cleaned and reused. With sleeved bores, the sediment has less chance to build up on a non-corrosive, smooth surface, simplifying cooler removal.
After the sleeving process is complete, any deteriorated sealing surfaces for orings or gaskets are repaired and brought back to OEM specifications.
