Belimo Experience Effciency

Intelligence down to the last detail.

«The question is not what you look at, but what you see.»

Henry David Thoreau, American writer and philosopher

We question what is already there.

That is how we create something new.

Those who have developed high-quality products are faced with two options: to declare themselves satisfied with what has already been achieved or to improve his performance systematically. We have decided on the second option and have invested more than others in research and development. In that we regard nothing as given and are dogged in our insistence on following new paths, surprising prospects with respect to both general and economic efficiency open up for you.

We set ourselves the highest standards in respect to convenience and energy savings. This is why we consider efficiency to be a comprehensive attitude. We define added value for customers and the environment as a triad made up of uncompromising quality, ecologically long service life and intelligent thriftiness.

We are redesigning the gearbox.

You receive compact, economical actuators.

Our gear wheels have been given a completely new, non-linear geometry. This unconventional adaptation is exceptionally effective: The motors become smaller and are given a new breakaway – precisely when they need it. For example, when a butterfly valve moves out of the sleeve gasket while opening or closing. This means that you are getting actuators with even greater ease of handling and thriftiness.

Conventional motor and gearbox combinations create a linear torque.

Force

This makes the actuators very energy-intensive. The S gearbox in

the Belimo motors achieve a very high torque for the first couple of degrees of rotation – a so-called breakaway torque with unchanging current – and reduces this to an absolute minimum for the remainder of travel to the required angle of rotation.

We detect the holding force dynamically.

You save energy.

Our patented motor control is equipped with a dynamic holding force detection. This means that only exactly the required curret is used to keep the dampers or valves in their position.

This results in a lowering of the annual energy consumption of the actuator by as much as 70%.

Dampers and valves are in movement only 5 to 15% of the time.

At the same time, the actuators are used to hold the final controlling elements in their current position – independent of changes in the

We put our faith in SuperCaps.

You require less current.

The trend-setting SuperCap technology is the intelligent and energy-efficient alternative to the mechanical spring-return. Because of the fact that the final controlling elements move electronically into their safety positions, the permanent energy against the spring is dispensed with. This means that you reduce electricity consumption of the actuators by up to 80%.

actuators with condensers store energy – in a way comparable to a reservoir – and do not release it until there is an electricity interruption, in order to move the damper or the valve into the desired safety posi­ tion. The specially low-friction gearbox makes it possible to keep the size of the condensers small and the design of the actuators compact.

We make valves leak-proof.

You avoid circulation losses.

If valves do not close completely tight, heating or cooling energy disappears unused in the pipe network on a continuous basis. Our compact, air bubble tight closing characterised control valves prevent such circulation losses – even with high differential pressures. In​ contrast to conventional metal seats, the spherical valve cones with precisely fitting resilient jointing do not cause any additional losses as they age. You then save energy on a perma­ nent basis throughout the entire service life.

The secret lies in the spherical shape of the valve cone and in the

We make energy currents visible.

You optimise the water circuits.

In addition to the flow rate, the sensors in our electronically regulated valves also measure the temperatures in the supply and return lines, e.g. with heat exchangers. The values are saved in the integrated webserver for up to 13 months and are visible, e.g. onsite on the laptop. The current consumption can also be depicted on the management system. This way, you can analyse and document which direction the energy is flowing to and optimise the energy flows of the hot and cold water circuits at any time.

The consumption of energy-intensive component such as coolers, boilers and pumps is often much too high if heat exchangers are not working efficiently. The integrated monitoring in our Energy Valve offers points of reference for recognising this. The «ΔT Manager» that is also

More comfort and at the same time massive energy savings: The MP-Bus速 from Belimo con足 veys the actual damper positions of the volumetric flow units and the needs signals from the room temperature controllers to our Fan Optimiser on a continuous basis. The Fan Optimiser calculates from this the actual requirements of the system and generates the control values for the ventilators. This way they achieve a considerable reduction in pressure loss and elec足 tricity consumption and an audible reduction the flow noise.
