Altecnic Matrix Midi 250D Twin Pump 5 bar Digital Pressurisation Unit

The Altecnic Matrix Midi 250D is a twin pump digital pressurisation unit rated at 5 bar, forming part of the Altecnic Matrix pressurisation units range. It maintains pressure in sealed heating and chilled water systems by introducing water when system pressure falls below the set point. The digital control governs pump operation and monitors pressure within the unit.

• System pressure cannot be maintained and low-pressure faults recur
• One or both pumps fail to run when system pressure drops
• The digital controller shows persistent fault indications or loses its settings
• Water weeping from the unit body, pump seals or connections
• Pumps run continuously or cycle excessively without holding pressure

• Confirm the installed unit is an Altecnic Matrix pressurisation unit and that the Midi 250D specification suits the system.
• Check the required pressure rating and pump configuration against the system design and the existing unit's duty.
• Verify pipework connections, electrical supply and control interface arrangements against the manufacturer's instructions before fitting.
