Mitsubishi Selfjector: SJ-G Series 


Selfjector / SJ / Oil purifier / Purifier / Disc type centrifuge separator


Note 1: Purifying system for low-grade fuel oils with densities up to 1.01 @15°C. As opposed to the conventional method of directly measuring the water content of purified oil, the H-HIDENS purifier is capable of detecting water in the oil accumulated in the purifier bowl, thereby preventing water from mixing in with purified oil.


Standard model (H)


Optional equipment

HIDENS model (HH)


Optional equipment

SUPER HIDENS (optional)

Like the H-HIDENS system, the SUPER HIDENS system can process high-gravity oils without having to replace the gravity disc. The pressure-sensor type water detection system uses an innovative automatic valve installed on top of the purifier that operates to discharge separated water in the rotating bowl, eliminating the need to operate main cylinder (valve).
