Mikrofill 3 PRO + 2 x 500 Litre MikroPro Vessels Pressurisation Set - Service Valve Included

Mikrofill 3 PRO with 2 x 500 Litre MikroPro Expansion Vessel Bundle

This bundle pairs the Mikrofill 3 PRO pumpless pressurisation unit with two 500 litre MikroPro expansion vessels (providing 1000 litres of combined expansion capacity), giving specifiers, installers, and facilities managers a complete, pre-matched pressurisation and expansion solution for domestic and commercial heating and cooling systems. The two 500 litre vessels are floor-standing, and purchasing the 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.

2 x 500 Litre MikroPro Expansion Vessels

The two 500 litre MikroPro expansion vessels included in this bundle are floor-standing and rated to a maximum operating pressure of 6 bar each, with a maximum operating temperature of 70°C. Constructed with a carbon steel shell and connections, a synthetic rubber compound diaphragm, and a durable powder epoxy coating, each vessel complies with the Pressure Equipment Directive (PED) 97/23/EC and carries CE certification. Splitting the 1000 litre requirement across two smaller vessels can suit installations where floor space, doorway access, or plant room layout make a single larger vessel impractical.

Why Choose the Bundle

Selecting the Mikrofill 3 PRO with two 500 litre MikroPro expansion vessels removes the guesswork from vessel sizing and ensures full compatibility between the pressurisation unit and expansion vessels from a single, trusted manufacturer. The bundle extends the Mikrofill 3 PRO's standard warranty from 2 years to 4 years, and units purchased as a package are factory pre-commissioned and supplied with a service valve, reducing on-site commissioning time.
