PDES – Pressure Ejection

PDES modules for the EPMS system

Description

PDES modules for the EPMS system are available with digital and analog manometer and one channel. They can be operated using an internal or an external valve. Maximum pressure is 4 bar / 58 psi.
By default the PDES modules come with an analog timer. For digital timing an additional module, TMR-02M, is required.

PDES systems are also available as 19″ stand-alone devices.
