OGA SISTEMVAC provides comprehensive solutions for the feeding and discharge of pressurizable hopper cars using pneumatic conveying systems for efficient bulk solids handling. These applications allow controlled unloading from hopper cars into storage silos, adapting dense, dilute, or semi-dilute phase conveying depending on product granulometry and bulk density. Load cells are integrated for gravimetric weighing and precise inventory tracking. The system includes automatic filters, rotary valves, calibrated pressure lines, and SCADA control for real-time monitoring. These solutions are designed to minimize unloading times and reduce losses.
