Bermad - Delta - Cloud Based Pressure Controller

The DELTA is a stand-out pressure management controller for system optimization. It provides a calmer network, improved efficiency, and a reduction of leakage and bursts. The result is a reliable water supply and better service for the client. The DELTA is a fully remote-controlled fail-safe battery-operated controller. The DELTA logs the data and uses cyber-secured technology to transmit the data to a user-friendly cloud platform.

Features and Benefits

• Up to 16 time or flow windows
• Highly accurate and stable regulation
• Latch override to fully open the valve at insufficient pressure supply, or fully close in the event of a pipe burst
• 5 years internal battery operated or external power
• Large capacity data logging
• Full communication via the cloud for monitoring and remote setting
• Intuitive and user-friendly platform
• Advanced modern graphs and reports
• Alert and notifications via: E-mail, WhatsApp, SMS

Applications

• Full modulation pressure reduction with the DELTA internal solenoids and a BIAS chamber
• 2 pressure regimes by switching between “Low” to “High” set points according to flow rate or time windows
