Centrifuge Drives REN2C

Controlled Centrifuge Drives REN2C of drilling rig

Capacity 11...90 kW

Developed to meet severe operating conditions IGBT-transistor variable frequency electric drives REN2C are designed for soft start and rotational speed control of the drilling rotary table of decanter centrifuge of any type. They also provide you with diagnosis and protective functions during any operational mode.

Benefits of using drive REN2C:

• optimal separation efficiency for every operational mode;
• high quality separation;
• considerable increase of machinery facilities and electrical equipment lifespan;
• reduce electrical costs and negative impact on the supply network while centrifuging;
• reducing electricity costs.

Drive REN2C provides:

• soft start of the centrifuge motor;
• enabling and disabling electric drive from remote panel; smooth change of the electric drive rotational speed from zero to the desired in manual mode;
• diagnosis of machinery facilities and electrical equipment;
• full range of electric drill protection from accidents and emergency situations;
