Pipe connection system for cascade heating unit has a modular design corresponding to the number of boilers

摘要

A pipe connection system for a cascade heating unit for two of more boilers has a modular design with each boiler connected to a section of horizontal pipe for the supply and return feeds for the heating system. The separate input modules are connected in series, as are the return modules, with the latter mounted below the supply modules. A hydraulic distribution system is set vertically to connect one end of the modules and comprises rectangular ducting. The separate modules are fitted with connections to the boilers.
