Advantages of an En-Masse Drag Chain Conveyor for a Central Heating System

Central heating systems, especially when older, can become costly due to their lack of efficiency and the large amount of maintenance they demand. A university located in North Dakota realized such a challenge with their aging central heating system. With the update came some strict budgeting goals and ROI stipulations. To go along with the high-efficiency boilers purchased by a […]

Choosing the Right Conveyor to Solve Feedstock Handling Challenges

A small power producer needed to supply a nearby malting facility with its electricity and heating needs. However, the power producer was struggling to do so due to unexpected downtime and poor material distribution due to the current conveyors at the facility. Material flow issues were due to the shortcomings of the layout and plant design. The original conveyor(s) were […]

Top En-Masse Design Elements for Ash Handling

Designing the conveyor from the inside out is a great method when engineering a piece of equipment. The full application and site details are collected, then the design work can begin with selecting the optimum chain for the application. Once the chain is chosen, the frame and components are then designed around it. That was the case for a new […]
