Koolmesh. One system – all solutions!

The energy calculation is “crazy”… With Exaktor’s Koolmesh lighting control, Anders Schultz and his colleagues are taking energy savings to a new level:

– Compared to an existing LED installation, you can reduce energy consumption by 60 per cent. If you switch from fluorescent tubes to LEDs, it can be up to 90 per cent.

What do you do when you get to work in the morning? Do you walk round and turn the water on all the taps, so that it runs at full flow? And then do you leave the water on all day, only turning it off when you go home? If you remember, that is… Well, I thought so. So isn’t it strange that many of us deal with lighting in just that way? Even though it uses a lot of energy unnecessarily? The solution is a smart control system,’ says Anders Schultz, Exaktor’s lighting control specialist.

– ‘It is an established truth that lighting control with presence sensors saves a lot of energy. But for a long time, it was quite cumbersome to install and many users found it difficult to use. We thought the market for control systems was unnecessarily complicated, so we decided to offer a smart and flexible system that works for everything.

Every possible scenario

Koolmesh is built on a Bluetooth-based mesh network where all luminaires communicate wirelessly with each other. What distinguishes Koolmesh from other systems on the market is that there is one sensor in each luminaire.

– Most other control systems work with groups. Only one luminaire in the group is equipped with a sensor that lights up all the other luminaires in the group. The disadvantage, apart from being slower, is that you can’t control with the same precision. It’s as if you go to the toilet on one floor and at the same time flush the one on the floor below,’ Anders Schultz reasons.

Controlling the lighting at luminaire level creates a host of advantages:

– This is a system that solves every conceivable scenario: presence, absence, zone, stand alone, schedule, push button, astro, stairwell, timer, daylight compensation, fire alarm, alarm and the possibility of integrating into other systems such as ventilation. The technology also makes it possible to avoid what is known as false detection, i.e. the lighting switching on in the wrong place or floor, for example, or in connection with machine cells.

Compare LED with LED

Installation is simple and cost-effective for the installer, and programming is easily done with an app on a phone or tablet.
In principle, the user should not have to do anything at all. If the property owner then wants to rebuild an office and move walls, there is no need to rebuild the entire system. It’s just a matter of reprogramming the luminaires.


– The energy calculation is crazy,’ says Anders Schultz:

– If you replace an existing LED installation with new luminaires with Koolmesh, you have an energy saving of about 60 per cent. So we are comparing LED with LED. We’ve almost stopped making calculations on old fluorescent luminaires, because it’s so obvious.

If you replace an existing LED installation with new luminaires with Koolmesh, you have an energy saving of about 60 per cent.
