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.
