Smart Energy

SMART ENERGY OPTIONSE-Savings-with-Cabinet-600px

The Smart Energy option incorporates an electric motor that runs at variable RPM, with closed loop control via an inverter drive and in parallel with the variable delivery of the pump. In this situation the controller optimizes the motor RPM with the displacement of the pump in order to deliver the required volume of oil in the most efficient combination. As well as providing improved efficiencies in all situations due to optimum motor/pump combination, remarkable savings are achieved during the idle parts of the cycle, notably during hold time and cooling phase. During these phases the electric motor can drop to 600 RPM therefore achieving a huge reduction in power consumption. Benefits of the Smart Energy option include:

  • Energy consumption as low as all-electric technology (depending on cycle breakdown)
  • Noise levels comparable to all-electric machines
  • Superior shot weight precision due to faster response time of change over to hold on pressure
  • Dramatically increased life of the hydraulic oil
  • Reduced chiller running costs
  • Increased hydraulic component life
