EPM Series
Oil Free Rotary Screw Compressor (37kW-280kW)
ULTIMATE ENERGY EFFICIENT INVERTER MODEL
The SCR EPM (15–45kw) and EPM2 (55-160kw) range pushes the boundaries of compressed air efficiency. The latest generation of the EPM2 series is class leading and has low energy consumption, resulting in reduced running costs and lower CO2 emissions. Like all SCR compressors, it is intuitive, maintenance friendly and exceptionally versatile with an environmentally responsible design.
FEATURES:
- Energy-saving variable speed control
- Super premium efficiency PM motor (IE4 equivalent)
- Morse connection design for motor and airend
- 30-100% variable speed range
- Oversized innovative cooling system
- Suitable for use up to 50°C ambient
INOVANCE VARIABLE SPEED DRIVE (VSD)
SCR VSD compressors in Australia have used Inovance VSDs for over ten years. Their innovative energy-saving features and proven reliability in some of the country’s toughest environments make Inovance the perfect choice for the EPM series.
DOUBLE VSD ENERGY-SAVING TECHNOLOGY
MAIN MOTOR INVERTER
DESIGN CONTROL
Stable constant pressure
The SCR EPM compressor’s wide operating variable speed range ensures stable constant pressure control and reduces power consumption. SCR’s exclusive inverter and energy-saving logic control can optimise energy savings regardless of the load condition. They can react to pressure changes quickly, maintaining pressure fluctuation at ±0.01 MPa.
FAN MOTOR INVERTER DESIGN CONTROL
Stable constant temperature
Setting a constant temperature ensures the best lubrication performance, avoiding high-temperature trips.
PURE SOFT-START SYSTEM AS STANDARD
Soft Start System Reduces Electric Current During Start-Up
The SCR EPM/EPM2 series adopts a soft start system for its start-up. Traditional motor starters, such as direct online and star-delta starters, burden the power supply due to the high peak start-up current, typically 3.5 times their full load current (FLC). With a variable speed soft-start system, the starting current never exceeds the rated value.
