Accurate Pressure Management

The Flamco Pro PU 281 Digital Pressurisation Unit continuously monitors system pressure using an advanced electronic pressure sensor. Whenever pressure drops below the programmed level, the digital controller automatically activates one of the twin pumps to restore the correct pressure.

As a result, heating and cooling systems remain protected from pressure fluctuations that could affect efficiency or damage valuable equipment. Furthermore, maintaining stable pressure helps improve overall system performance while reducing unnecessary maintenance.

Twin Pump Reliability

One of the key advantages of the Flamco Pro PU 281 Digital Pressurisation Unit is its intelligent twin-pump design. Instead of relying on a single pump, the unit automatically alternates operation between both pumps to distribute running hours evenly.

Moreover, if one pump requires maintenance or develops a fault, the standby pump immediately takes over. Consequently, the system continues operating without interruption. This redundancy makes the unit particularly suitable for critical commercial buildings where continuous operation is essential.

Intelligent Digital Controller

The integrated digital controller offers simple operation and accurate pressure adjustment. In addition, the user-friendly display allows engineers to configure system settings, monitor operating conditions, review alarms, and access diagnostic information with ease.

Because of its intelligent design, commissioning is straightforward while long-term maintenance becomes quicker and more efficient.
