VarioFlow plus Stainless steel system STS

The Bosch Rexroth VarioFlow+ stainless steel system is a modular chain conveyor platform designed for applications requiring high hygiene standards, utilizing robust stainless steel construction throughout the transport mechanism. This system serves primarily the food processing, pharmaceutical, and beverage industries where contamination control is critical. The modular design enables flexible adaptation to various production line configurations while maintaining consistent material flow rates. Available components include horizontal curves with radii from R500 for 160mm to 320mm widths, straight track profiles, and connection units for seamless integration into existing manufacturing processes.

Selection criteria for VarioFlow+ stainless steel components center on conveyor width ranging from 160mm to 320mm, curve radius specifications of R500 for directional changes, and available angles including 30°, 45°, 90°, and 180° configurations. The system utilizes 48.3mm diameter tubing with 1.5mm wall thickness in 3000mm standard lengths for structural support profiles. Basis units are available in 65mm and 90mm heights for direct connection applications, with all components designed for 12mm x 30mm profile compatibility. Track profile lengths extend up to 3024mm for straight sections, enabling spans suitable for medium to large-scale production lines without intermediate supports.

VarioFlow+ stainless steel conveyor systems comply with EN 1672-2 for food processing machinery safety requirements and DIN 10506 for hygienic design principles in food equipment. The stainless steel construction meets material standards according to DIN EN 10088 for corrosion-resistant steels used in food contact applications. Components are designed to fulfill HACCP guidelines for hazard analysis and critical control points in food production environments. The modular design approach adheres to ISO 14159 safety standards for machinery design, ensuring proper guarding and operational safety protocols are maintained throughout the system lifecycle.

The VarioFlow+ stainless steel system offers horizontal curves in three width variants of 160mm, 240mm, and 320mm, each available with R500 radius geometry for consistent material flow characteristics. Curve angles span from 30° for slight directional changes to 180° for complete reversals, with intermediate options of 45° and 90° for typical production line layouts. Straight track profiles are manufactured as VFPlus STS1/2 12X3024 sections for standard applications, while support profiles designated 160-320+ STS 12X3024 provide structural reinforcement across all width variants. Connection basis units differ in height specifications of 65mm and 90mm to accommodate varying elevation requirements within the conveyor network.

VarioFlow+ stainless steel systems require mounting surfaces capable of supporting distributed loads across 12mm x 30mm profile interfaces, with connection points spaced at standard 3000mm intervals for structural tubing integration. The modular components utilize standardized coupling mechanisms enabling direct connection without specialized tooling or welding procedures. System compatibility extends to existing Bosch Rexroth aluminum profile frameworks through dedicated adapter components, allowing mixed-material installations where hygiene zones transition to standard industrial areas. Installation clearances must accommodate R500 curve radii with minimum 250mm additional space for maintenance access around conveyor perimeters.

VarioFlow+ stainless steel conveyor systems operate within temperature ranges from -10°C to +80°C for standard food processing applications, with specialized variants available for extended temperature exposure up to +120°C in pasteurization environments. The stainless steel construction provides IP54 protection rating against dust ingress and water splash, suitable for washdown procedures in food production facilities. Load capacity specifications range from 15kg/m for 160mm width configurations to 35kg/m for 320mm variants, with maximum conveyor speeds limited to 0.5m/s for product stability. All electrical components integrated into the system maintain IP65 protection levels for reliable operation in humid processing environments.

VarioFlow+ stainless steel conveyor systems require daily visual inspections of chain tension and track alignment, with weekly lubrication of drive mechanisms using food-grade lubricants meeting NSF H1 certification standards. Monthly maintenance includes thorough cleaning of all stainless steel surfaces using alkaline detergents followed by acid rinse cycles to prevent mineral buildup and maintain corrosion resistance. Annual inspections must verify structural integrity of support profiles, measure chain elongation against manufacturer specifications not exceeding 1.5% of original length, and confirm torque settings on all connection hardware remain within specified ranges. The system design life expectancy reaches 15 years under normal operating conditions with proper maintenance protocols consistently followed.
