Flamco Pro PU 261 Digital Pressurisation Unit – Twin Pump – 1-6 Bar

The Flamco Pro PU 261 Digital Pressurisation Unit – Twin Pump – 1-6 Bar is a premium digital pressurisation solution developed to provide accurate pressure maintenance for sealed heating, cooling, and chilled water systems. Designed specifically for demanding commercial and industrial applications, this advanced unit ensures consistent operating pressure while protecting valuable HVAC equipment from pressure fluctuations.

Maintaining the correct system pressure is essential for the efficient operation of any sealed heating or cooling installation. The Flamco Pro PU 261 continuously monitors system pressure using an advanced electronic pressure sensor. Whenever pressure falls below the programmed set point, the unit automatically activates one of its high-performance pumps to restore the correct pressure quickly and efficiently.

One of the biggest advantages of the Flamco Pro PU 261 is its twin pump configuration. Unlike single-pump units, this model automatically alternates between both pumps during operation to distribute running hours evenly. This intelligent duty-sharing significantly extends pump life while ensuring maximum reliability. If one pump becomes unavailable, the standby pump automatically takes over, allowing the system to continue operating without interruption.

The digital microprocessor controller provides exceptional accuracy and user-friendly operation. The clear display allows installers and maintenance engineers to adjust pressure settings, configure operating parameters, monitor alarms, and review operating history with ease. Password protection prevents unauthorised changes while maintaining system security.

The integrated break tank ensures a safe and reliable water supply for automatic system top-up. The unit also includes numerous built-in protection features such as dry-run protection, anti-seize pump cycling, overflow monitoring, and automatic fault diagnostics. These intelligent functions help minimise maintenance requirements while protecting the pumps from unnecessary wear.
