Eco Shock Series ES4A

• 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.
• No reduction in pumping speed at all pressure range
  ECO-SHOCK doesn’t depend on dry pump revolving-speed-control,for that there
  is no degradation of the exhaust speed.
• Easy installation
  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.

SPECIAL FEATURES / FURTHER 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
