Standard Compressor Package Includes:
COMPRESSOR: Single-stage, flooded, rotary screw airend with the power-saving, proprietary SIGMA Profile delivers pressures up to 217psig.
INTEGRATED REFRIGERATED DRYER: CFC-free R134a refrigerant, pressure dew point as low as 38°F, moisture separator and Eco-Drain, completely piped and ready for installation, stainless steel plate type heat exchanger for high efficiency and low pressure drop
ELECTRIC MOTOR: TEFC, 208-230/460V, 3-phase, 60Hz, 3600rpm, class F insulation, and EISA compliant. Units can be wired in the field for 208V, 230V, or 460V. Other voltages are available, as well as 50Hz. Consult factory for pricing.
STARTER: Magnetic Wye-Delta reduced voltage starter ensures low starting current and soft start (DOL for SX 3 and single phase models).
DRIVE: Maintenance-free elastic belt does not require re-tensioning and maintains efficient power transfer from the motor to the airend.
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.
AIR/COOLANT SYSTEM: Cooling air enters the package through a replaceable and cleanable package prefilter. A solid steel floor ensures that cooling air must pass through the prefilter. A 4-mircon air intake filter with replaceable, 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 the 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. Combination valve incorporates a thermostatically controlled valve, cooler by-pass, and micro fluid filter. The thermostatically controlled valve ensures perfect regulation of the fluid temperature. The micro fluid filter utilizes a spin-on cartridge. Main fluid and compressed air lines are made of 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. Enclosures features a durable powder-coated finish. Compressor is mounted on base frame with a solid steel floor and vibrations isolation mounts. Additional vibration isolation for airend, motor, and separator tank is 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 the belt tensioning without opening the machine.
Receiver Tank: Dryer and Compressor will be mounted with all associated piping leading into an integral ASME Certified 52.8 gallon air receiver. Complete with safety relief valve, gauge, and internally coated for increased corrosion resistance.
Protective Devices: Sigma Control Basic, safety pressure and relief valve, emergency stop button and oil level sight glasses. The drive access door is equipped with door interlock switch, which shuts down compressor if doors are opened while unit is running.
Devices for Ease of Maintenance: Fluid exchange pressurization valve complete with drain hose; large gasketed and hinged 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.
