The Wilo-Isar MODH1 is a pressure-boosting system with multistage, horizontal fix speed pumps, which is suitable for water supply and boosting in small commercial buildings thanks to its compact, space saving design. Its modular construction can be fitted optionally with one, two or three pumps of the type Wilo-Medana CH1-L. Components with fluid contact are also suitable for drinking water applications. Flexible connections, its small space, its service-friendly hydraulic components and the Easy Controller make installation, commissioning and maintenance very easy.
