N E T2MATERIAL HANDLING SOLUTIONSPROVEN & DEPENDABLEFrom receiving to load-out, each day your facility moves, weighs, loads, and samples millions of tons of material. The success of your operation relies not only on the quality of the commodity but the dependability of the equipment used to keep it moving. InterSystems’ bulk material handling systems offer the speed and reliability you need to satisfy customers and grow profits.From a modest beginning in 1959 as a maker of cardboard doors for rail boxcars, InterSystems has evolved into a worldwide manufacturer of a full line of bulk material handling equipment. Placing a customer-centric focus on the engineering and manufacturing process, InterSystems’ product solutions include bucket elevators, bulk weighers, enclosed belt conveyors, en-masse and self-cleaning en-masse conveyors, gravity screeners, truck probes, automatic samplers, micro ingredient systems, bolted bin systems and distributors. Purchased by GSI in 2014, InterSystems' material handling equipment can be found around the world at grain elevators, in processing plants and at port facilities handling a wide variety of commodities including grains, powders, rock and wood pellets.InterSystems believes that “custom” is standard, displaying a willingness to change in order to meet the needs of your specific applications with a solution. Behind each product line is an engineer leading a team dedicated to design improvements which promote efficiency and keep current with changes in industry regulations. Our in-house customer service team is on-call to assist with replacement parts or installation questions and can deploy a field technician to analyze problems and recommend solutions. InterSystems does it all while maintaining industry-leading delivery times.www.intersystems.net | www.grainsystems.comINTERSYSTEMS EN-MASSE CONVEYORS3InterSystems’ models of En-Masse Conveyors offer the best value in the industry. With more than 30 years of manufacturing experience, InterSystems delivers with quality, performance, and service after the sale. InterSystems has popularized features including a bolted box design which eases the replacement of liners. Knowing the heart of any conveyor is the chain, our designs include slack chain and choke switches, speed-to-length ratio chain calculations, and specific chain working load calculations – all developed to ensure precise applications.For higher strength and longer life, InterSystems utilizes roller chains for the majority of our En-Masse Conveyor models. These chains are precision-built with press-fit joints.InterSystems has developed two En-Masse Conveyor models based on capacity needs. The 12/17 Series, for average capacity, utilizes a horizontal bearing mount. The higher capacity 26/33 Series has a much stronger, reinforced head design with a 90-degree rotated bearing mount which facilitates the application of bigger drive components.From simple storage to critical environments, there is an InterSystems conveyor to meet your needs.COMPLETELY ENCLOSED FOR CLEAN PLANT OPERATIONLARGE CAPACITIES FOR CONVEYING IN A COMPACT SPACECONVEYING THAT INCLINES UP TO 90 DEGREESVARIETY OF SIDE AND BOTTOM ABRASION RESISTANT (A.R.)
