GRUNDFOS MAGNA Grundfos MAGNA Amazingly adaptable Intelligent, speed-controlled circulators for heating and air conditioning systems

Mighty MAGNA: Reliable. Adaptable. Powerful. The prestigious new HQ of the Barmenia insurance company in Germany uses MAGNA pumps to ensure reliable air conditioning - circulation of 12°C water in their system’s fan coils.

MAGNA highlights Permanent-magnet circulators with plenty of edge Meet the MAGNA - a design pioneered by Grundfos. This circulator pump is built around a permanent-magnet motor and an integrated frequency converter to ensure maximum efficiency. An efficiency so superior that every MAGNA is rated “A” for its energy consumption - one of the first circulators to receive that distinction. Since its first launch in 2001, the MAGNA range has gone from strength to strength. By popular demand, the range has been expanded in both size and scope. Now, it comprises 28 different models and works equally...

Comfort or efficiency? Adapting means getting the balance right Proportional pressure savings Proportional line Proportional-pressure control Groundbreaking work by Grundfos led to the discovery of proportional-pressure control. In units employing this principle, the differential pressure across the pump is automatically adjusted to match the flow. When the flow falls, so does the pressure required. This results in a correspondingly reduced load on the motor – and reduced energy consumption. And things get even better when you add the AUTOADAPT function.

AUTOADAPT: The crowning glory of the MAGNA The AUTOADAPT feature is unique to Grundfos. It adds real intelligence to the MAGNA, learns what works best for your system – and changes the settings accordingly. AUTOADAPT helps during all stages of the pump’s life. It brings you simple and accurate specification, easy installation, reliable operation, high comfort, and energy savings that go on and on. Ideal balance between comfort and efficiency The AUTOADAPT function regularly adjusts the proportional pressure and automatically sets a more efficient performance curve whenever possible. But it never...

Calculate your savings! Replacing existing pumps can greatly reduce energy consumption. This simple form gives you an idea of how much you could save with new MAGNA pumps. An example 4 x 100W pumps from 1994 -> 4 x 105 kWh = 2 x 900W pumps from 1994 -> 2 x 3880 kWh = 2 x 400W pumps from 1999 -> 2 x 945 kWh = Total savings per year with MAGNA pumps = To make your own calculations, visit www.grundfos.com/MAGNA.

Upgrade to an “A”. It pays. There are over 120 million circulator pumps in operation throughout Europe today. Most of them are inefficient. Replacing those inefficient pumps with new, A-rated alternatives will reduce energy consumption by more than 70%. So even if the pumps are not broken, replacing them makes perfect sense. Short payback times Cutting energy consumption by more than 70% has a real impact on electricity bills. In fact, the payback time of an A-rated MAGNA replacing a D-rated older pump can be as little as 18 months. That’s something to bear in mind for future site visits. Instant...

Amazing technology Threaded or flange connection MAGNA pumps are available with threaded or flange connections for easy installation into new or existing systems. Permanent-magnet rotor The MAGNA pumps use a revolutionary motor design where the rotor is based on permanentm ­ agnet technology, gene­ rating greater energy savings than any other speedcontrolled circulator pump. Optimised hydraulics The MAGNA pump housing and impeller are designed to be a perfect match. Extensive 3D testing and simulations ensure that the hydraulics in the MAGNA pumps are as efficient as possible – thereby reducing...

User-friendly interface The MAGNA user interface is simpli­ city itself. The operating panel restricts itself to showing only the most essential performance parameters, making it easy to read. It clearly indicates the flow rate and the operating level of the pump in relation to maximum capacity. And pump performance can be adjusted manually with a simple press of a b ­ utton. Extensive communication and control options MAGNA pumps are designed to optimise the system of which they are a part. So naturally they give you the communication and control facilities you need. Bus communication enables...
