HV SERIES – 132kw-280kw
Highest efficiency 2 stage VSD rotary screw compressor range (132kW-280kW / 102cfm-1130cfm)
Description
SCR HV2 Series
2 Stage Variable Speed Drive (132kW-280kW)
ULTIMATE ENERGY EFFICIENT 2 STAGE COMPRESSOR
The H/HV 2 stage series range pushes the boundaries of compressed air efficiency. The latest generation of the H/HV 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 (HV series)
- Super premium efficiency motor
- Fixed speed H series range available
- 30-100% variable speed range
- Oversized innovative cooling system
- Suitable for use up to 50°C+ ambient
INOVANCE VARIABLE SPEED DRIVE (HV SERIES)
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 HV series.
DOUBLE VSD ENERGY-SAVING TECHNOLOGY
MAIN MOTOR INVERTER DESIGN CONTROL
Stable constant pressure
The SCR HV 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.
PURE SOFT-START SYSTEM AS STANDARD
Soft Start System Reduces Electric Current During Start-Up
The SCR HV 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.

HOW THE TWO-STAGE AIRENDS WORK
The SCR Two Stage essentially has two airends, one large low pressure airend and one smaller high pressure airend, both integrated within the same airend “block”. Atmospheric air enters the low pressure airend and is pressurised to around 50% of the final pressure. The pressurised air then enters the second ‘high pressure boosting airend’ where air is compressed to the final pressure. The lower compression ratios in each airend offer superior volumetric efficiency, lower vibration, lower noise, higher reliability and lower heat generation on compression. As a result of these mechanical efficiencies, the two-stage airend can produce more air, which in turn can lead to a lower kW compressor being used to supply your air requirements. With power costs being the greatest cost factor when buying a compressor, this can lead to a significant saving over the life of your air compressor. The standard airend found in most compressors must compress the atmospheric air up to the final discharge pressure in a single-stage and requires more energy and generates more heat.
TWO-STAGE FEATURES
- The rotors are meshed and sealed with an oil film belt to reduce wear
- R&D in Japan
- Reduces the compression ratio with each compression
- Reduce energy consumption
- Low differential pressures
- Improved volumetric efficiency
- Low thermal load
- Longer life span of bearing
WHY TWO-STAGE COMPRESSION SAVES MORE ENERGY
Isothermal compression saves the most energy
- AFE31 is area of isothermal compression
- ABC31 is area of standard compression
- AB, BF, FD, 31 is area of two stage compression
- Two stage compression saving area is BCDF comparison with standard compression
After first grade compression, the volume of compressed air becomes smaller, then the second compression uses smaller roto, which reduces the compression leakage.
This reduces compression ratio which reduces leakage.
