Mikrofill 3 PRO + 50 Litre MikroPro XP Potable Vessel Pressurisation Set - Service Valve Included

Mikrofill 3 PRO with 50 Litre MikroPro XP Potable Expansion Vessel Bundle

This bundle pairs the Mikrofill 3 PRO pumpless pressurisation unit with a 50 litre MikroPro XP potable expansion vessel, giving specifiers, installers, and facilities managers a complete pressurisation and expansion solution suitable for potable water systems as well as heating and chilled water circuits. Purchasing the two products as a bundle extends the standard warranty on the Mikrofill 3 PRO from 2 years to 4 years.

This bundle set is supplied with a service valve included as standard.

Mikrofill 3 PRO: Fully Automatic Pressurisation

The Mikrofill 3 PRO is a fully automatic, WRAS-approved sealed system filling device that manages system pressure with minimal maintenance. It delivers a maximum inlet pressure of 9.0 bar and a maximum cold fill pressure of 8.7 bar, alongside patent-pending smart fault logic that identifies faults faster and improves system uptime. Measured fill volume, leak detection, and MODBUS RTU connectivity give installers and building management systems a clear, accurate picture of system performance, while the unit's IP55 rating and compact wall-mountable design suit a wide range of plant room environments.

50 Litre MikroPro XP Potable Expansion Vessel

The 50 litre MikroPro XP expansion vessel included in this bundle is WRAS-approved for potable water applications and rated to a maximum operating pressure of 10 bar, with a maximum operating temperature of 70°C. Constructed with a carbon steel shell and threaded connections, a synthetic rubber compound diaphragm, and a durable powder epoxy coating, the vessel complies with the Pressure Equipment Directive (PED) 97/23/EC and carries CE certification. This size features a replaceable diaphragm, supporting easier long-term maintenance.
