COMPRESSED AIR IN AN ENERGY EFFICIENT MANNER
HUME DOORS & TIMBER recently invested in an energy efficient Kaeser CSD 125 rotary screw compressor to meet the increased demand for compressed air created by the expansion of its Sydney manufacturing facility.
Hume Doors and Timber (Hume) is one of Australia’s largest door manufacturers with operations in every capital city and strategically placed regional branches within Australia and New Zealand.
Hume provides innovation in doorway technology and manufactures an extensive range of over 2000 products for the building industry including the commercial and industrial, multi- unit, aged care, residential and renovation sectors. From its manufacturing facilities Hume is able to deliver specialist low volume to mass high volume production. In fact, it was the first company to introduce cold pressing technology to allow for the mass production of doors using sustainable practices – a procedure that also greatly reduces power consumption.
Hume is committed to operating its entire business process in an environmentally sustainable manner. As such its manufacturing and distribution processes have been designed to minimise its environmental footprint. Innovation, sustainability and recycling therefore all have a key role in its manufacturing facilities. One way it tries to minimise its environmental footprint is by utilising energy to its maximum efficiency.
It’s no surprise then, that when it comes to the compressed air systems at all of its manufacturing operations, Hume has long since opted for compressed air equipment that is not only reliable but also highly energy efficient. Compressed air is an important utility to Hume and can be found in use across the manufacturing process, responsible for powering the woodworking machinery such as the sanders and staple guns.
Hume recently expanded its manufacturing operation in Sydney. With the expansion came an increased demand for compressed air which the current system could not meet. Eddie Luke, the General Manager at Hume contacted Kaeser Compressors for a solution.
Kaeser recommended and subsequently installed a CSD 125 rotary screw compressor to meet Hume’s increased demand for compressed air in the most energy efficient manner.
The CSD series rotary screw compressors push the boundaries when it comes to compressed air efficiency. These versatile compressors provide significant energy savings in four key ways, states Kaeser:
• At the heart of every CSD system lies a premium quality rotary screw compressor block featuring Kaeser’s energy- saving Sigma Profile rotors. Operating at low speed, the rotary screw compressor blocks are equipped with flow optimised rotors for superior efficiency. The newly- refined rotors found in the latest generation models, together with additional optimisation measures such as reduced pressure losses, are now delivering between three and six percent better specific power performance compared to previous models.
• Kaeser’s 1:1 drive design additionally delivers superior efficiency by eliminating the transmission losses associated with gear or v- belt driven systems. 1:1 direct drive rotary screw compressors provide outstanding performance and enable significant savings.
• Featuring an IE4 super premium efficiency drive motor further maximises energy efficiency. IE4 motors are the technology of tomorrow, as current regulations introduced in January 2015 simply require the use of IE3 class motors. IE4 motors comply with and exceed prevailing New Zealand EECA regulations for three phase electric motors.
• Finally, the Sigma Control 2 industrial PC- based internal controller ensures efficient control and system monitoring. This dynamically adjusts flow rate to match actual compressed air demand thereby assuring further energy savings.
The fixed speed CSD series of rotary screw compressors from Kaeser are available with working pressures 7.5 to 13 bar, motor power 45 to 75 kW and free air deliveries 5.50 to 12.02 m3/min.
