INVT GD270: Intelligent Control Expert for Building Water Supply Systems

The optimal choice for achieving constant pressure water supply in buildings
Modern high-rise buildings have increasingly high requirements for water supply systems, not only ensuring stable water pressure, but also requiring energy conservation and efficiency. The INVT GD270 frequency converter can achieve constant pressure water supply through precise PID control, maintaining stable pipeline pressure regardless of floor height and water consumption. It supports multi-stage pressure setting function, which can automatically adjust the water supply pressure according to the water usage pattern in different time periods, reduce pressure at night and during holidays when the daily water consumption is low, and save energy.

2. Multi pump control system improves water supply reliability
INVT GD270 can control a water supply system consisting of up to 8 water pumps, using a cyclic variable frequency control method to automatically balance the operating time of each water pump. When a water pump malfunctions, the system will automatically switch to other water pumps to ensure uninterrupted water supply. In addition, the frequency converter also supports the fire control function of the fire pump, shielding fault alarms in emergency situations and continuously outputting to ensure water supply.

3. Multiple protection functions ensure system security
INVT GD270 provides comprehensive protection functions, including overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, etc. It also has a water pipe rupture detection function, which can timely detect water pipe leakage problems; The water shortage protection function prevents the water pump from idling and being damaged; The motor overheat protection function protects the motor by detecting its temperature. These protective functions greatly enhance the security and reliability of the system.

4. Intelligent management improves operation and maintenance efficiency
INVT GD270 supports multiple communication interfaces and can easily connect to Building Automation Systems (BAS) for remote monitoring and centralized management. Management personnel can view the real-time operating status, current, voltage, frequency and other parameters of each water pump in the monitoring center, and can remotely set operating parameters and start stop equipment. The system can also automatically record operational data and fault information, facilitating equipment maintenance and fault analysis.
