Grundfos the company specialising in pumps has launched a pump that is according to the firm the market’s most efficient and comprehensive for both heating and cooling systems. The new model is the MAGNA3, with an average Energy Efficiency Index (EEI) of 0.18, which is below the level established by the EuP Directive and represents a 75% energy savings compared to traditional circulation pumps.
This model is based on the proven technology of the former MAGNA: the permanent magnet engine, Autoadapt function, and integrated frequency converter. The company has expanded its range to more easily size the models to meet any work conditions and cut costs in the process, both when purchasing the product as when it comes to energy savings. It has also increased the maximum pumping height up to 18 meters and flow to the 70m3 / h.
It is suitable for heating and cooling systems as well as for recirculation of hot water for sanitary use. It is designed to handle liquids below -10 o C making it perfect for both extremely hard industry works as for geothermal systems (GSHP).
An advantage of one of their systems is that it allows to largely set aside external regulating valves facilities.
Thermal power meter
The new MAGNA3 features one standard thermal power meter that monitors and controls the power distribution and consumption system. Thus, excesses in the electricity bill caused by imbalances in the system and installation costs arising from having to install separate external device such as energy meter are avoided.
The installers will be able to implement this technology with the tracking software that has been incorporated into a high-resolution screen to follow-up the whole process. They can also keep track by using the remote control software, enabling them to easily monitor, configure and control the pump.
