RBG 1000 ISD

Separate dispersion and control unit, pressure resistant at over-pressure values up to 3 bar, optional low pressure operation from 300 mbar (absolute pressure), nitrogen as dispersion gas as well.

•    Pressure-resistant up to 3 barg overpressure
•    2 m distance between dispersing unit and control unit
•    Optional:Low pressure operation from 300 mbar absolute
•    Nitrogen as dispersing gas
•    Optional: Remote control or computer-controlled

Description

This device disperses particles at positive pressure values of up to 3 bar and can also use nitrogen, in addition to air, as the dispersing gas.

Optional operation with low pressure from 300 mbar absolute is possible (please see accessories).

Please note: The 7-, 10-, 14- or 20-mm feed stock reservoirs are pressure-resistant.

For operation with low pressure special pressure-resistant feed stock reservoirs are needed. Their piston is strongly connected to the feeding unit by a claw. This enables an undisturbed operation with low pressure. Old RBG models can be upgraded with this function by Palas®.

The solid material reservoir with a diameter of 28 mm is not pressure-resistant, but can be used with the RBG 1000 SD under atmospheric conditions.
