An online software package from Teseo calculates the return on investment on the company’s modular pipework systems. By inputting a few parameters, users can calculate values for pressure drop, absolute initial pressure, length of the distribution line, flow rate and diameter of the company’s piping. With the new module, the user can perform an approximate estimation of ROI in months, comparing the economic benefits of the company’s solution with other systems (conventional iron, round aluminium, steel). Parameter comparison and total costs are based on estimates for load losses, annual volume of air leaks, implementation and maintenance costs. The software also offers an approximate estimate of the cost effectiveness of replacing an old plant, indicating the age of the piping network and the percentage of leaks.
