They are the ideal heating solution. Wherever ceiling heights exceed four meters. Radiant tube heaters are energy saving, cost-effective, flexible and highly reliable. No wonder we concentrate on
this special type of infrared heating for large spaces.


Our radiant tube heater portfolio is among the most extensive in Europe. Probably even worldwide.
Its heating systems come in an impressive variety of performance categories that are
designed for different temperature zones and for large facilities of all kinds. For total, partial or even individual area heating. And they are expandable to highly efficient integrated systems such as H.Y.B.R.I.D.

Why radiant tube heaters are so much better. And why you benefit.

Radiant tube heaters need less energy. That is why they are so good, especially when it comes to heating large spaces. And there is much more. For example, because radiant tube heaters are decentralized heating systems, heat is generated directly where it is needed. Advantages for you include: no separate boiler room, no pipelines, no transport losses and no more complex infrastructures. Decentralized systems are very easy to operate – and flexible for every type of building use, even if this should change.

Infrared heat is particularly pleasant. After all, it resembles the natural heat of the sun. So there are no different temperature layers, no heat accumulation, no swirling dust – just balanced, draft-free and direct warmth.

Just take a look at this advantage: Radiant tube heaters have closed combustion so exhaust gases can be discharged in a controlled manner. This enables the use of collective exhaust systems and residual heat – and thus of highly efficient integrated systems such as H.Y.B.R.I.D.

"With almost 70% energy savings, my investment in infrared heating has just paid for itself."

For faster ROI. For a better environmental performance. For your facilities.

A special kind of infrared heating. And by far the best technology for heating facilities. This our belief and our conviction. We have been radiant tube heaters for more than a quarter of a century – and have been constantly pushing the possibilities of this energy-saving technology to the limit. For even more performance. For even less consumption. Basically: outstanding energy efficiency is our burning passion.

Up to 70% energy savings
Cost reductions, even in the 6-figure range
ROI in 2 to 5 years
Compliant with the strict leading German environmental laws such as EnEV 2014 and EEWärmeG 2015
Countless tons of CO2 emissions saved
Supports your efficiency goals e.g. according to DIN EN ISO 50001


Optima was a leap forward in innovation. The first consumption-optimized infrared heating solution on the market. That was in 1996. Since then, hardly any other system has been able to surpass its efficiency and performance. The latest generation of high-performance radiant tube heaters from KÜBLER is called OPTIMA plus. Achieving up to 72% infrared radiation, it can be used directly and loss-free in the work area. This system is considered one of the most efficient infrared heating solutions ever. A stand-alone mega-performer – thanks to KÜBLER'S creative development team.

"340,000 euros savings make infrared heating technology a significant economic factor."

Christian Hamann,
Wippermann jr. GmbH


Heating technology of the highest energy-efficiency level. Coupled with an easy-to-use control system developed at KÜBLER, one that reflects our know-how of 30 years. Plus a collective exhaust system which integrates residual heat utilization. Heating solutions from KÜBLER are far more than the sum of their parts. They are overarching concepts that are carefully honed down to the last detail. Which is why their reliability and energy balance are so exceptionally good.
