INVT GD270 VFD Powers Smart and Efficient Water Supply with One-to-Two Pump Control

High-rise buildings are a business card of the modern city, and the number of people living in high-rise buildings is also increasing, and the problem of water consumption is also gradually exposed. Living community water supply process, if the tap water supply for some reason insufficient pressure or short-term water cuts, will affect the lives of residents, so the traditional water supply control system is gradually replaced by frequency conversion system.

The water consumption in a residential area fluctuates greatly, and the pumps, which have been in the industrial frequency rated state for a long time, have high electricity costs, increased mechanical wear and equipment failures, and shortened lifespans. Therefore, it is necessary to upgrade the water supply control system in order to control the water supply to the floors with constant pressure and to realize energy saving.

INVT Solution

With the rapid development of power electronics technology, the performance advantages of frequency conversion speed control system is becoming more and more obvious, INVT use GD270 VFD for constant pressure water supply control of water on the floor, the pump adopts the mode of one tow two, to realize the pump cycle, to achieve energy saving, and prolong the life of the motor effect.

- GD270 series VFD for fans and pumps Advantage:
* Quick to install and use: integrated functions for applications in the fan and pump industry (HVAC).
* Energy saving and high efficiency: integrates a new ECO energy saving algorithm to save operating costs.
* Protection upgrade: The core circuit board comes standard with a thicker protective coating.
* EMC performance is guaranteed.
* Has constant pressure water supply energy saving function

Customer Benefit

* Cost: The maximum can realize one tow 8 cycle water supply function, VFD selected P-type machine corresponding to the motor power, the use of one tow two applications, saving equipment costs;

* Efficiency: able to realize rapid acceleration and deceleration, the pump speed for a short period of time to the working frequency, to protect the water supply of the community;

* Energy saving: the power factor of the motor, reducing the input current, reducing the operating frequency, energy saving efficiency of about 30% or so, about annual savings of more than 20,000 yuan in electricity costs.

INVT GD270 frequency conversion constant pressure water supply control system, not only has a separate constant pressure water supply can also be used with multiple pumps at the same time, to ensure the quality of water supply in the community, energy saving effect is obvious, high reliability.
Therefore, the community water supply control system design for energy saving and improve the quality of water supply has an important practical significance, to promote residential water supply management to modernization, technology, intelligent transformation.
