1: 1 Direct drive System Means no drive belts to service, improved reliability, zero energy losses (standard drive belts may lose between 4% and 11% of the energy transferred from motor to compressor) and very low rotational speed for a longer service life..Variable speed drive - Latest generation technology providing maximum energy savings and a subsequent reduction in CO2 emissions. The system provides a continuously adjusted air output in line with your actual usage, meaning that you only generate the volume of air that you need- Reduced energy wastage- NO over pressurisation and up to 28% reduction in the energy consumed.Low noise levels. The Nobel operates more quietly than competitive compressors. Thanks to the direct drive system, low rotational speed of the compressor, temperature controlled cooling and sophisticated cabinet design the Nobel range offers noise levels as low as 58 dB(A)Highest performance. Thanks to the direct drive system, lower rotational speed, lower temperature and optimised air end design, Nobel provides higher output with lower power consumption when compared to other compressors.DNAIR 2 Controller. The Nobel is fitted with the advanced controls. The simple clear back lit display is menu driven and allows full programming features as well as advanced safety features. The controller provides a control capability for up to 4 compressors and is fully programmable. The DNAIR2 is fitted with sophisticated diagnostics and prepared ready to accept our remote service and monitoring tool (SMS).Advanced cooling system. The deployment of the thermostatically controlled centrifugal cooling fan with the large surface area heat exchanger for the air and oil cooling ensures, lower operating temperature and lower air outlet temperatures. The automatic operation of the centrifugal cooling fan saves energy by only operating when required.Robust and reliable - The NOBEL is designed for continuous use in tough conditions ensuring reliability and a very long life.Simple maintenance - All service items are located in one position with easy access reducing costs and down time.Cabinet pre-filtration - ensures that internal components are highly protected which means improved reliability, much better cooling and reduced maintenance.IE3 High efficiency Motors - Allowing reduced energy consumption.
