Overview
At Elmo Rietschle, Application-Specific Systems are engineered-to-order (ETO) vacuum solutions tailored to the needs of distinct industries and processes (bottling, plastics extrusion, degassing, priming, Life+ processes). These systems combine bespoke design, advanced vacuum technologies, and a focus on efficiency, sustainability and reliability.

Bottling Systems

• X-VLU and X-VSI dry vacuum bottling systems derived from the BF product line.
• Dry technology (C-VLU claw and S-VSI screw pumps) to save water and energy.
• Variable Speed Drive (VSD) for precise pressure control and process adaptation.
• Heavy-duty XD version with ProCoat coating for improved corrosion resistance.
• High-efficiency gas/liquid separators with automatic drainage reduce foaming and enable continuous operation.
• Pump flushing and drying systems to remove process residues and maintain pump performance.
• CIP-compliant designs to enable Clean-In-Place of separation systems.
• Integrated monitoring (temperature and pressure) of cooling circuits and advanced control systems for safe, continuous operation.

Degassing & Priming Systems
Custom vacuum solutions for degassing, priming and related processes (distillation, impregnation, heat treatment). Systems are optimized for precise vacuum control and robust, continuous industrial operation.

Plastics Extrusion Systems

• Solutions for extrusion, pelletizing and compounding focusing on consistent product quality.
• Dry-technology options eliminate wastewater and reduce environmental impact.
• Enhanced vacuum control and modular configurations for adaptation to different extrusion setups.
• Advanced separation and parallel separator configurations for continuous operation and easier cleaning.
• Pumps flushing/drying and corrosion-resistant options for improved reliability.

Operating Principle
Application-specific systems integrate the appropriate vacuum technology (claw, screw, rotary vane, liquid-ring, radial) with system-level components (separators, drains, VSD, control and monitoring) to meet the defined process requirements and performance targets.

Process: Needs Analysis → Design → Integration → Sustainable Operation → Testing & Deployment

• 1. Needs Analysis: Collaborative evaluation of process requirements to define system scope.
• 2. Custom Design: Select and size pumps, separators and auxiliaries; design for CIP, drainage and material compatibility as required.
• 3. Integration & Optimization: Implement VSD, advanced control and monitoring; optimize piping, separators and instrumentation for performance.
• 4. Sustainable Operation: Favor zero-water or recirculation cooling, IE4 motors and energy-efficient pump technologies.
• 5. Testing & Deployment: Factory testing and validation to industry standards prior to site commissioning.
