MOLOSsafe Systems for Silo Filling Protection

MOLOSsafe systems from MOLLET Füllstandtechnik provide reliable, autonomous protection for silos during pneumatic filling with bulk solids. They prevent overfilling, overpressure, underpressure, filter damage, and environmental contamination, ensuring safe and professional silo filling processes.

Types

• MOLOSsafe-SSS — Complete autonomous silo overfill protection system (full package).

• MOLOSsafe-SFA — Silo filling device (self-acting shut-off valve) as a basic component or standalone unit.

• MOLOSpressdec-MSD (series) — Pressure monitoring devices for silos and containers during filling.

• Supporting components — Microwave flow monitors (MOLOSflow-FSM) and sine pinch valves (MOLOSvalve-QV) for enhanced flow control and shut-off in filling lines.

Characteristics

• MOLOSsafe-SSS: Includes full detector (level switch), automatic silo filling valve, pressure monitoring, control unit, acoustic horn/signal; can be expanded with additional modules (e.g., filter monitoring, selection switches); ATEX-certified versions available.

• MOLOSsafe-SFA: Self-closing shut-off valve at the filling line connection; activates automatically on imminent overfill; standalone capable; ATEX options.

• MOLOSpressdec-MSD: Monitors positive and negative pressure; protects against excessive overpressure or vacuum; adjustable settings; ATEX-compatible.

• Robust, dust-tight design; integration into existing pneumatic filling systems; reliable electrical/mechanical operation; optional features like key switches for supervised filling or release.

Advantages

• Comprehensive, independent protection against overfilling, overpressure damage, filter failures, and material spills — significantly reduces risks and downtime.

• Automatic shut-off and alarm functions minimize human error and ensure compliance with safety standards.

• Modular and expandable design allows customization to specific plant requirements.

• High reliability in harsh industrial environments; easy integration and low maintenance.

• Prevents costly accidents, environmental pollution, and production interruptions during bulk material delivery.

• ATEX approvals ensure suitability for explosive dust atmospheres.

Applications

• Pneumatic filling of silos and containers with bulk solids (cement, grain, powders, chemicals, lime, feed, plastics, etc.).

• Silos in cement plants, feed mills, grain storage, chemical processing, food production, building materials, and agriculture.

• Facilities with truck or rail tanker deliveries requiring safe, automated overfill and pressure protection.

• Plants in potentially explosive (ATEX) zones needing certified safety systems.

• Any bulk solids handling operation where reliable prevention of overfilling, pressure issues, or wrong filling is critical.

These MOLOSsafe solutions form the core of safe bulk solids handling at MOLLET, perfectly complementing level measurement and coupling systems.
