Flamco Pro PU 161 Digital Pressurisation Unit – Single Pump – 1–6 Bar

The Flamco Pro PU 161 Digital Pressurisation Unit is engineered to maintain accurate pressure in sealed heating and chilled water systems. It continuously monitors system pressure and automatically adds water whenever the pressure falls below the preset level. As a result, the system remains protected while boilers, pumps, valves, and associated pipework continue operating efficiently. This intelligent pressure management also helps reduce maintenance requirements and extends the service life of connected equipment.

Designed for commercial and industrial installations, this floor-standing unit combines dependable performance with advanced digital controls. It offers a maximum operating pressure of 6 Bar and a flow rate of up to 18 litres per minute, making it suitable for medium and large HVAC systems. Furthermore, the compact cabinet allows engineers to install the unit quickly without occupying unnecessary plant room space.

Intelligent Digital Pressure Control

The integrated microprocessor controller automatically monitors pressure, controls filling operations, and provides clear system information through a digital display. In addition, engineers can adjust pressure settings in small increments to match individual system requirements. The electronic pressure transducer continuously measures operating conditions and immediately reacts whenever pressure changes occur.

Moreover, the controller records operating events, stores alarm history, and provides service reminders that simplify planned maintenance. Consequently, engineers can identify potential issues early and minimise unexpected downtime.

Reliable Single Pump Performance

The single high-performance pump delivers consistent pressure maintenance while operating efficiently throughout daily use. Likewise, the automatic filling function restores system pressure without requiring manual intervention. This helps reduce maintenance time while ensuring stable operating conditions.

An integrated break tank supports safe water management and helps the unit comply with current water regulations. Furthermore, the durable construction protects internal components and provides dependable long-term performance in demanding commercial environments.

Advanced Protection Features

Safety is an important part of the system design. Therefore, the unit includes dry-run protection, pump anti-seize protection, flood protection, and intelligent runtime monitoring. These features help prevent unnecessary wear while protecting both the equipment and the heating installation.

In addition, password-protected programming prevents unauthorised setting changes. The unit also supports MODBUS RTU communication, allowing straightforward integration with modern Building Management Systems (BMS). As a result, facility managers can monitor and manage system performance from a central location.

Ideal Applications

This pressurisation unit is suitable for offices, schools, hospitals, hotels, apartment developments, manufacturing facilities, and other commercial buildings with sealed heating or chilled water systems. Moreover, its intelligent digital controls improve operational efficiency while reducing ongoing maintenance costs.

Whether installed in a new project or replacing an existing pressure maintenance system, the Flamco Pro PU 161 Digital Pressurisation Unit provides reliable automatic pressure control, intelligent monitoring, and dependable long-term performance.
