Multi-Stage Roots Type Dry Vacuum Pump

Power Saving Attachment

ECO-SHOCK:ES4A

アルバック

ECO-SHOCK is a revolutionary dry pump accessory that can reduce power consumption by attaching to the dry pump exhaust line.
Patent is registered (China,Japan,Korea,Singapore,Taiwan)

Features

  • ECO-SHOCK contributes to energy saving
    - The power consumption of the dry pump can be reduced substantially.
    (Ex.)Max. 59% of power reduction at ultimate pressure running and 34% of power reduction at repeatedly chamber gas exhausting.
    (Ratio of our company's LR3601-R) *1 *2 *3
    - As the effect which suppresses the heat generation of the dry pump, it can reduces the electric power of the air-conditioning equipment too.
  • Excellent results when used with a multi-stage root type dry pump. *4
    Very effective when dry pump runs lower than 1000Pa.
  • ECO-SHOCK doesn't depend on dry pump revolving-speed-control,for that there is no degradation of the exhaust speed.
  • Easy installation by attaching a valve unit to the exhaust pipe. *5 *6

*1 Measure example of 300L chamber repeatedly air exhaust in the tact of 60 seconds.
*2 Not capable to use in applications such as flammable, burn ability and toxic gas exhausts or for solid/fluid suction.
*3 Power reduction ratio depends on the attachment model and the conditions of use.
*4 Dry pump which exhaust port can operate with no problem under vacuum is applicable. Do not install to the dry pump which exhaust port can not operate under vacuum.
*5 The installation method differ on the dry pump model type and structure.
(A modification is required with LR3600,LR3601(-R)pump to mount ECO-SHOCK)
*6 Modification could be required prior to installation of the ECO-SHOCK.

Applications

  • Countermeasure for dry pump power saving
    - Power saving of dry pumps that is used in frequently exhaust such as Load / Unload chambers.
    - Power saving of dry pumps where is using a big amount sealing gas. - Power saving of dry pumps that the exhaust velocity is high at atmospheric pressure.(Example)Equivalent to ULVAC's model LR180,LR421,LR3600,LR3601,LR3601-R
