KEY FEATURES & BENEFITS
The Kaishan Compressors Australia KRSA Single Stage Low Pressure Rotary Screw Air Compressor is engineered with cutting-edge technology to deliver unparalleled performance and efficiency. Among its standout features and benefits are:
WORLD CLASS ENGINEERING
PATENTED ‘SKY’ SINGLE STAGE AIREND
Continual trial and development has created an advanced airend that increases compressor efficiency by more than 20% over earlier models.
- Larger Rotor Size To increase the rotor throughput, the airends of our PMV compressors are larger than usual. They are built with 5/6 lobes and larger rotor size which reduces the specific power consumption whilst operating at low speed.
- Lower inter-lobe leakage losses Pressure differences between two neighbouring work chambers is small due to a greater number of lobes. This reduces inter-lobe leakage losses, hence leakage to delivery ratio decreases as the number of lobes increases.
- Larger wrap angle & discharge port A greater number of lobes combined with larger wrap angle ensures multiple rotor contact. This reduces vibration which minimises noise. Larger discharge ports decrease the discharge velocity and therefore reduce the discharge pressure losses increasing the compressor’s overall efficiency. ‘
Kaishan KRSA compressors are built to be compatible with the optional VFD feature. KRSA Variable Speed Air Compressors provide maximum efficiency with consistent operation. Unlike conventional ‘Auto-dual’ and ‘Load/No load’ control modes, KRSA VFD modulates the speed of the drive motor in response to system demand. This results in greater energy saving compared to a fixed speed compressor. The VFD feature greatly reduces the starting power surge of the motor. A constant pressure delivery extends the life of valves.
- Industry renowned VFD units are used in KRSA series compressor packages.
- Compact VFD design allows a smaller footprint.
- Accurately measures key functions of the unit.
- Maintenance free operation.
- Minimises starting current peak loads.
- Performs at extremely low sound level.
