MIKROFILL MINI 230

Digital Pressurisation Unit

Compact, Powerful, and Built for Precision

The Mikrofill MINI is a compact yet highly efficient pressurisation unit, engineered for large domestic and small commercial sealed systems. Whether used for heating systems, chilled water systems, refrigeration units, or industrial cooling, the Mikrofill MINI delivers exceptional pressure control with ease.

 

Housed in a robust, compact enclosure designed for wall mounting, the MINI is remarkably easy to install and commission. Despite its small size, it offers a 3.0 bar cold fill pressure and a 2-litre tank capacity, making it ideal for systems of up to 6,000 litres.

 

Equipped with an advanced digital control system and automated top-up features, the MINI guarantees precise and reliable operation. The unit also includes a high-flow, KIWA-approved fill valve, ensuring efficiency and dependability in every installation.

 

Perfect for maintaining pressure in heating, cooling, and industrial applications, the Mikrofill MINI ensures consistent, low-maintenance performance, making it the go-to choice for smaller-scale sealed systems.
