SCOPE OF SUPPLY
SFC 45 Rotary screw compressor is designed for the performance specified herein. The Kaeser rotary screw compressor
includes the following standard features and accessories:
Compressor
• Single-stage, fluid-injected rotary screw compressor with the power-saving Sigma Profile airend
Electric Motor/Drive
• Premium efficiency TEFC drive motor with thermal overload protection, 150% minimum pull-up torque and Class F
insulation
• Synchronous Reluctance Motor with IES2 provides improved efficiency to the entire drive.
• Automatic tensioning device for belt drive
Protective Devices
• Built-in protective devices include safety pressure relief valve(s), emergency stop button, airend discharge temperature sensor, enclosure and guards for moving parts & compressor shutdown for voltage protection on AC variable frequency drives
Air/Coolant System
• 1-micron air intake filter with cleanable and replaceable element
• ASME fluid separator tank with 3-stage separation ensures minimal fluid carry-over of 1-3 ppm (by weight)
• Fluid level sight indicator on the separator tank
• Filter mat on fluid and air coolers simplifies cooler maintenance
Enclosure
• Soundproofed enclosure features lined panels and a durable powder-coated finish. Compressor is mounted on solid base
frame with a solid steel floor and anti-vibration mounts. Additional vibration isolation of airend, motor and separator tank is standard.
• Single removable panel provides access to all maintenance components, including two windows to view fluid level and belt tension.
Sigma Control 2 TM
• Sigma Control 2TM: PC-based control system with Intel® processor and real-time operating system. It monitors all critical compressor and control functions and maintains a non-volatile memory of the last 100 messages for ease of trouble-shooting and record keeping. Remote start/stop, programmable timers and two-unit sequencing are standard features
• The Sigma Control 2TM offers the choice of Quadro, Vario, Dual, Continuous and Dynamic control. Idle-period timer shuts the compressor down if air is not required for a preset period dependent on selected control mode.

Variable Speed Drive
• Siemens AC variable frequency drive using Pulse Width Modulation technology and a “soft start” system for unlimited
motor starts, all integrally mounted and wired in the compressor package.
• Variable frequency drive control efficiently adjusts compressed air output during fluctuating demand requirements to maintain system pressure within ±2 psig by reducing or increasing airend speed. An idle period timer shuts the
compressor down if air is not required for a preset time.
• Variable frequency drive allows for an effective flow range of about 25 to 100% and is ideally suited for partial loads of 40 to 85%. EMI filters provide safety and reliability.
Refrigerated Dryer (On T Models)
• Optional integral refrigerated dryer with moisture separator and demand trap.
• Built-in refrigerated air dryer provides pressure dew points as low as 38°F with minimum pressure drop.
• N/A
Warranty
• Twenty-four (24) hour emergency parts guarantee (standard units only - see price list)
• Standard twelve (12) month warranty on compressor package for materials and workmanship
• Standard twenty-four (24) month limited warranty on airend, motor, and Sigma Control 2
• Optional sixty (60) month limited warranty on Sigma Control 2 controller, airend and motor
