Pressurisation Unit SPU 150 MIDI

The Stuart SPU Midi range of digital pressurisation units represent the next generation of automatic filling and pressure maintenance solutions for sealed heating and chiller systems.

Capable of filling a system from empty and then monitoring and maintaining the design fill pressure in sealed systems, Stuart SPU Midi units are exceptionally easy to install and commission and are housed in a compact and robust enclosure suitable for either floor or wall mounting.

Units are available with one (duty), or two (duty-standby) premium quality Stuart peripheral pumps featuring all brass pump heads and continuously rated induction motors.

Utilising an unique microprocessor controller and pressure transducer, these systems feature an intuitive and easy to use menu based control system, self-diagnostic functions, configurable volt-free contact alarm connections and a Building Management System Modbus interface.
