Boss MX130 - Product Description; Operating Principle

MX130 & MX230
6. Product description
The MX130. MX230 is a compact and totally enclosed digital pressurisation unit with electronic
pressure transducer and user-friendly microprocessor for use on sealed systems in order to
provide a minimum system pressure requirement.
This equipment is not designed to cope with sudden, substantial, losses of system
pressure (e.g. manual draining) or major water losses (e.g. large leaks). The
equipment is also not intended to be used for water boosting (potable) applications.
6.1. Operating principle
The function of this pressurisation unit is to provide a means of automated water top-up to sealed
heating and cooling systems. The equipment is designed to provide periodic water top-up to
compensate for minor losses in system pressure (e.g. slow leaks, air venting, etc.).
This equipment is not designed to cope with sudden, substantial, losses of system
pressure (e.g. manual draining) or major water losses (e.g. large leaks). The
equipment is also not intended to be used for water boosting (potable) applications.
