ENERGY SERIES             

Direct driven variable speed rotary screw air compressors

The ENERGY Series variable speed screw compressors allow for power savings on average between 30-40% over conventional controlled compressors. ENERGY Series allows for an air supply with minimal peaks, in doing so supplying only the air required for production minimising service costs and operating costs. Designed to operate in the harshest working conditions 24 hours per day, the Energy Series controller is able to control up to 6 units from one common control panel. All Energy Series compressors are equipped as standard with power filters, harmonising the incoming voltage and protecting the inverter and compressor components from electrical surges.

 

The Controller

The advanced computer controller allows for the ENERGY Series to be interfaced with up to 6 compressors. The controller allows for the compressor to be individually programmed to meet specific site requirements, in doing so minimsing operating costs. Simple controls allows the unit to advise maintenance intervals and diagnose faults.

 

Variable Speed Drive

The inverter and controller ensure for precise control of pressures and volume of the compressor by monitoring production requirements and varing the compressor output and speed without the use of an encoder.

• Motor starting torque of up to 200%
• Accurate torque control
• Torque response time of 1-2ms
• Main motor protection and cooling fan protection
• Direct response air volume to motor speed
• Air pressure adjustable from 6 to 10 Bar (13 on request)
• Air supply monitoring and adjusting from 25% to 100% of load
• Directly driven air end with efficiency up to 99.9%
• Soft start reduces current peaks and allows for additional energy savings

The initial capital outlay of any air compressor represents on average a small percentage of the total cost of operating the compressor over its operating life. The absorbed power of any compressor represents the highest cost of the unit over its operating life. Compressed air, if incorrectly used, is one of the most expensive forms of services any production facility will operate. The installation of an ENERGY Series variable speed drive air compressor will on average reduce the running costs by between 30% to 40% when compared to a conventional motor.
