4. Products Features：
l Energy efficiency. Compared to the old water supply method, the constant pressure water-cooled inverter VFA-60L series water supply system with VFD inverter saves up to 20%-60% of water & electricity. |
l The installation is very easy with direct screw thread, it can be used different kinds of water pumps and thus reduce extra costs. Built-in check valve |
l It is applied to all applications where maintaining a constant water pressure in the water supply system, as well as control and protection of a pump motor that controls automatic start and stop by various electrical systems is required. |
l This water-cooled inverter VFA-60L series can be combined into pump groups of up to 6 pumps. The group is controlled by one main controller selected by the user while other controllers adjust the operation to the system requirements. The set is very easily programmable and does not require the assistance of the programmer |
5. FAQ
Q: How can I order your products?
A: You can send us enquiry to ask for details of prices, delivery term, lead time etc.,by mail, WeChat or WhatsApp or other communication tools.
Q: What does it mean that the VSD water-cooled inverter adapts to the motor power below 2.2KW?
A: It means that it can be used for 0.75KW, 1.1KW, 1.5KW, 2.2KW (power below 2.2KW) water pump
Q: Can the input frequency of this water-cooled inverter be 50HZ and output frequency be 60HZ?
A: The input frequency and the output frequency are the same, if the input frequency is 50HZ, the output frequency is 50HZ.
l Q: Can your VFD inverter be used for deep well pumps? What are the requirements?
A: The frequency inverters we produce can be used for deep well pumps, we suggest that the power cable is no longer than 20 meters. The power of the VFD inverter should be bigger than that of the deep well pump.
Q:If the inverter is connected to the power, after the power is turned off and then turned on again, will the inverter start automatically the water motor?
A: Yes , it will.
Q: Can you provide packing details for this product?
A: For inverters power below 2.2KW, there are 6PCS in a CTN;
Q: What kind of transportation can you provide?
A: We can provide shipping by sea, air and express.
Q：What is the difference between this and the air-cooled inverter?
A: The VFA-60L series are water-cooled inverters, which are mainly cooled by flowing water; while the conventional air-cooled inverters are mainly operated by fans to cool down, relatively speaking, the noise of the inverter is smaller.
Q：Is it possible to order the inverter?
A：We are a frequency converter production factory, with a research and development team, can provide OEM or ODM, etc., please contact us for specific details, thank you!
