This unit can meet demands like time proportional pressure maintenance and can be used with simple operation.● Optimal for pressure control and constant-value control for a long time.● Can control the waveform from the controller.● Compact and compatible with various installation sites.● Since neither oil cooler nor cooling piping is necessary, it can be easily handled.● Unlike control by a relief valve, only the necessary amount of hydraulic oil is discharged, resulting in efficient operation and low-power consumption.● For details, request the catalog on our website. https://www.rikenkiki.co.jp■Application example (destructive test, creep test)The Esperpack controller can set thenumber of repeat times (1 to 9999) of a pattern. The time of one step can be set in incrementsof 1 second. For safety, Esperpack has abreakout detection function, which stops theunit automatically if the test specimen isdamaged.■Application example (hot press)When heat is applied during press work, even if a workpieceis expanded or contracted due to heat, Esperpack detects achange in pressure and automatically correct the changedpressure, resulting in precise control regardless of changesin the operating environment.98
