Standard Compressor Package Includes:

 

Compressor:  Single stage, oil flooded rotary screw airend with SIGMA’s power saving proprietary profile.

 

Electric Motor:  TEFC, 208~230/460V, 3 Phase, 60 Hz., 3,600 rpm, Class F insulation and EISA compliant.

 

Starter:  Magnetic Wye-Delta reduced voltage starter ensures low starting current and soft start.

 

Drive:  Multi-ribbed belt drive with automatic tensioning device provides optimum power transfer and long belt life. 

 

Sigma Control 2™ System: This intelligent control comes standard with multiple pre-programmed control profiles so you can select the one that best fits your application. Sigma Control 2 monitors more than 20 critical operating parameters, shuts the unit down to prevent damage and signals if immediate service is required. It also tracks preventative maintenance intervals and provides notice when PM’s are due. Sigma Control 2 has superior communications capabilities. An Ethernet port and built-in web-server enable remote access and seamless integration into plant control/monitoring systems. ModBus, Profibus and other industrial communications interfaces are also available as plug-in options.

 

Protective Devices:  Sigma Control Basic, safety pressure valve, relief valve, emergency stop button, and oil level sight glasses.  The drive access door is equipped with door interlock switches which allows automatic shut down of the compressor if the door is opened while unit is in operation.

 

Air/Coolant System:  Cooling air enters the unit through a replaceable and cleanable packaged prefilter. A solid steel floor ensures that the cooling air must pass through the prefilter. 1 micron air intake filter with replaceable and cleanable cartridge extends fluid drain intervals and airend life. Pneumatic inlet and vent valve.  Combined reservoir and separator tank with 3-stage separation system ensures minimal fluid carry over of 1 to 3 ppm (by weight).  Quick change devices on separator and cooler allow complete, fast, and easy fluid changes.  ASME separator tank is equipped with quick disconnect fittings for manual verification of separator element contamination. The micro fluid filter utilizes a spin-on cartridge. Main oil and compressed air lines are rigid pipe and incorporate flexible pipe connections.  Units are air cooled with high efficiency coolers.  Internal air fan provides intensive cooling.

 

Enclosure:  Compact unit is soundproofed by a sheet metal enclosure with mineral wool and plastic liners.  Enclosure features a durable powder coated finish. Compressor is mounted on a solid frame with metal floor and anti-vibration mounts. Additional vibration deadening for airend, motor, and separator tank are standard.  Unit is very maintenance friendly with easy access to all important components through a single removable cabinet panel with key lock.  All maintenance items are accessible from one side, and windows in the panel allow viewing the fluid level indicator and belt tensioning device without opening the machine.

 

Devices for Ease of Maintenance:  Fluid change pressurization valve complete with drain hose; large hinged sealed door and removable

cabinet panel with key locks. 

 

Warranty:  Original KAESER SIGMA airend, electric drive motor, and Sigma Control are warranted for a period of two years against defects in materials and workmanship.  The balances of the components are warranted for one year.

Optional Five Year Extended Warranty Program:  KAESER will extend warranty coverage for 5 years on the airend, motor and Sigma Control (Parts & Labor).  All components not specified in the above description are subject to the terms of KAESERS standard warranty policy.  To qualify for the extended warranty, a customer must purchase one “5 year Warranty Maintenance Kit” at the time of the compressor purchase and one “5 year Warranty Maintenance Kit” each year of the term of the extended warranty.  These new kits include maintenance parts and fluid required for a machine running in a one shift environment.  Machines running more than one shift will require additional parts and fluid.  Replacement parts and fluid must be genuine KAESER parts.  The kits include micro-fiberglass oil filters which are a requirement for the Extended Warranty Program.  The fluid included with the kits is S460 Synthetic Lubricant or FG460 Food Grade Lubricant.   After the initial fill is removed from the compressor, the compressor must run S460 or FG460 for the life of the Extended Warranty Program.  We have a free Lubricant Analysis Program as a required part of the Extended Warranty Program.  Recommendations of the Lubricant Analysis Program will supersede the instruction manual.
