What it is
The Matrix Midi 135D is a single pump digital pressurisation unit manufactured by Altecnic for the Matrix range of pressurisation units. It maintains pressure within sealed heating and chilled water systems by monitoring system pressure and topping up as required. The digital control set provides a 3.5 bar pressure duty point.
Signs this part needs replacing
- System pressure falls below the set point and is not restored by the unit.
- The pump runs continuously or cycles repeatedly without holding pressure.
- Fault indications or alarms are shown on the digital control.
- Water is visible around the unit, indicating an internal leak or failed seal.
- The unit fails to start when system pressure drops.
Before you order
- Confirm the required pressure duty for the system is 3.5 bar.
- Check that a single pump unit matches the installation, rather than a twin pump arrangement.
- Verify the electrical supply and connections available at the installation point.
- Confirm the unit is being fitted to an Altecnic Matrix pressurisation unit installation.
