Optimal pressure boosting by intuition

The Wilo-Isar MODH1-E-2/3 booster system is a highlyefficient, convenient and operationally-reliable premium level solution for water supply in drinking, cooling and process water applications.

Rising energy costs and environmental regulations in the building and industrial sectors mean components such as pressure-boosting systems must operate at maximum efficiency. To save time for specialist technicians and building operators in their daily routines, these components must also be easy to install and user-friendly for commissioning and system profile adjustment.

However, and most importantly, pressure-boosting systems must function reliably to minimise failures in water supply.

Modular construction

The Wilo-Isar MODH1 is a pressure-boosting system that satisfies all these requirements. Equipped with multistage, horizontal, fixed-speed pumps, WiloIsar is suitable for water supply and boosting in small commercial buildings thanks to its compact, spacesaving design. Its modular construction can be fitted optionally with one, two or three pumps of the type Wilo-Medana CH1-L. All the pump components that come in contact with the fluid are made of 1.4301/1.4404 stainless steel.

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.

Hydraulics are optimised for reduced frictional pressure losses, while the IE5 motor satisfies the highest demands for energy efficiency. In addition, the full graphics colour display – with plain text and intuitive menu navigation – allows the pressureboosting system to be put into operation and controlled quickly and easily.

Wilo-Isar MODH1E provides reliable water supply at all times.

The protection functions include overload protection, dry-running protection and low water cut-out switchgear with automatic deactivation.

Reliable water supply

This high-quality, pressure-boosting system, with its compact design and integrated protection functions, enables the Wilo-Isar MODH1E to provide reliable water supply at all times. Furthermore, significant energy savings are achieved through highefficiency motors and optimal integral load adjustment. The colour display enables optimal operating convenience by displaying plain text.
