Standard Equipment Includes:
Compressor: Single stage, flooded, rotary screw airend with the power saving, proprietary SIGMA profile.
Motor: TEFC electric motor, 1-Phase, 60 Hz., 208 ~ 230., 3,600 rpm, class F insulation, 1.15 service factor and EPAct compliant. Other voltages are available upon request.
Starter: Magnetic wye-delta reduced voltage starter ensures low starting current and soft start.
Drive: Maintenance-free elastic belt doesn’t require re-tensioning and maintains efficient power transfer from motor to the airend.
Control Panel: Sigma Control Basic: PLC-based control system with monitoring of emergency stop, motor overload, direction of rotation, airend discharge temperature, refrigerated dryer, analog inputs, cabinet temperature, service hours, back pressure, and minimum starting temperature.Sigma Control Basic ensures economic operation by means of the optimized start-stop control system. This allows the unit to run either fully loaded or off-line to reduce power requirements.
Protective Devices: Built-in protective devices include safety pressure relief valve, emergency stop button, and fluid level sight glasses
Refrigerated Dryer: Single hook up integrated dryer; CFC free R513a refrigerant; 38 deg. F. pressure dew point; stainless steel plate type heat exchanger; moisture separator and Eco-drain. Complete piped internally and ready for installation
Air/Coolant System: Cooling air enters the package though a replaceable and cleanable package pre-filter. A solid steel floor ensures that cooling air must pass through the pre-filter. 4 micron air intake filter replaceable, cleanable cartridge extends fluid drain intervals and air end 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 rigid pipe and incorporate flexible pipe connection. Units are air cooled with high efficiency coolers. Internal fan provides intensive cooling.
Enclosure: Compact unit is soundproofed by a rotation molded double walled, polyethylene enclosure. Compressor is mounted on base frame with a solid steel floor and vibration isolation mounts. Additional vibration isolation for airend, motor, and separator tank is standard. All maintenance and service items are easily accessible once the unit’s removable enclosure is easily lifted away. The electronic condensate drain can be inspected through a pop-out window that also provides access to the condensate drain test button.
Air Receiver: Internally powder coated, includes an electronically controlled condensate drain.
Devices for Ease of Maintenance: Enclosure comes off for easy access for all filter and fluid exchanges; fluid change pressurization valve complete with drain hose; filter mat removal without tools; long life fluid filter.
Warranty: Original KAESER SIGMA air end, electric drive motor and Sigma Control are warranted for a period of two years against defects in materials and workmanship. The balance of the components is 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.
