The SmartTop is specifically designed for projects where there is a need for maximising local skilled labour content without compromising on the gas tightness, factory-level quality control, and overall functionality of the BiogasPro.
This is achieved by splitting the BiogasPro digester horizontally into two components with the bottom tank-type section built in place with cement and a sealing compound. The base tank (reactor) component is constructed using either bricks and mortar or a reinforced concrete in formwork approach, and the SmartTop is attached with bolts and a bitumen sealing compound.
It is critical that there is a skilled, experienced bricklayer in charge of the base construction. This is NOT a project for unskilled labour. Over and above the local labour benefits, this approach opens up the opportunity for increasing the size of the reactor itself by making a deeper base, at a marginal extra cost. The result can be a reduced per-cubic metre digester system cost with all the BiogasPro benefits.
