Water extraction, whether for household use, agricultural needs, or the needs of a large factory, should always be efficient, trouble-free, and smooth. To achieve this goal, however, it is very important to use suitable accessories that are distinguished by high quality and are fully compatible with one another. One of the features worth using is a frequency inverter—an element that is not only recommended but even essential for the proper operation of the entire system. What are frequency inverters? What are their characteristics? How do they work? And why is it worth using them? We explain these issues in our article.
Frequency inverter—characteristics and applications
A frequency inverter is an electronic device that enables the control of one or more pumps. Other names for it include a frequency converter and CPS frequency converter. The main task of this important component is to maintain the appropriate pressure level, regardless of the current demand for water. Using a frequency inverter saves electrical energy while increasing the efficiency of the entire installation, ensuring excellent and quiet operation as well as system reliability.
A frequency inverter is not only a recommended component but even an essential one for the proper functioning of a modern installation. This small device makes pump operation convenient and automatic. It is therefore no surprise that frequency inverters can be found in many installations, including:
- professional water supply systems that provide water to single-family homes,
- systems used to irrigate gardens and agricultural fields,
- industrial systems whose smooth operation is essential for the proper functioning of machinery,
- as well as systems designed to lower the groundwater level.
Submersible pump with a frequency inverter—why is it worth it?
Frequency inverters are used in both small and large water systems because they offer many advantages. Some of them include:
- versatility and the ability to use them in households, farms, horticulture, sprinkler irrigation systems, construction, water supply systems, and industry,
- elimination of the pressure tank, which requires a large amount of space,
- a guarantee of constant pressure regardless of water consumption,
- no pressure surges and, consequently, a longer service life for both the pump itself and the entire installation,
- no so-called water hammer,
- reduced electricity consumption: using a frequency inverter can lower the operating costs of a submersible pump by up to 40%,
- additional features, such as automatic restarting, which improves convenience,
- an alarm log that informs us about current hazards,
- dry-run protection, which minimizes the risk of pump seizure,
- overload protection, particularly if the pump impeller becomes blocked,
- protection against low and high voltage,
- protection against phase loss and phase asymmetry,
- convenient and quick installation,
- convenient operation, with a menu also available in Polish,
- compatibility with most pumps available on the market (however, please note: frequency inverters work with pumps of different power ratings, so it is necessary to check all the basic parameters),
- the ability to build multi-pump systems and operate up to six pumps,
- various installation options: wall mounting, installation on the discharge pipeline, or direct mounting on the pump,
- high quality and low failure rate.
