RBG 2000 SD

Pressure-resistant at positive pressure values of up to 3 bar, also nitrogen as a dispersing gas

    Optimal short-term and long-term dosing constancy
    Double the dosing time in comparison with the RBG 1000
    Disperses virtually any non-cohesive dusts
    Easy to switch out different solid material reservoirs and dispersion covers
    Easy to determine and adjust the mass flow
    Able to adjust higher mass flows than the RGB 1000
    Pulse mode
    Easy to clean
    Quick and easy to operate
    Reliable function
    Low maintenance
    Reduces your operating expenses

Description

This device disperses particles at positive pressure values of up to 3 bar and is able to use, besides air, nitrogen as dispersion gas.

Please note: The 16-, 20-, and 28-mm solid material reservoirs are pressure-resistant; the 32-mm solid material reservoir is not pressure-resistant. The solid material reservoir with a diameter of 32 mm is able to be used in the RBG 2000 SD exclusively under atmospheric conditions.

Nitrogen cannot be used as the dispersing gas in the pressure-resistant version of the RBG 2000.
