Our energy-efficient infrared heating systems began with the Optima product line. Since then, we have been continually innovating this successful series.

The latest generation is called OPTIMA plus because there is more to it than ever before. What has remained since the beginning is its powerful performance. And its talent as an efficiency all-rounder. Whether your ceilings are 3.50 m or 35 m high: the OPTIMA plus infrared heating solution works perfectly in both.

homogeneous preparation of the gas-air mixture.

The benefits OF THE OPTIMA plus.

72% usable energy*


Today's demands for maximum energy efficiency have a new gold standard: radiation efficiency. OPTIMA plus can offer you up to 72%. A crucial advantage
because every percentage point helps protect the environment - and improves your operating result.
ROI in 2 to 5 years


Your investment in OPTIMA plus pays for itself in just 2 - 5 years. And the effect on your operating result is even quicker: your company's liquidity is increased in the first year by the savings in energy costs. It is good to know that investing in modern heating technology pays off so fast.
70% fewer CO2 emissions


Depending on the project, up to 70% in energy can be saved compared to conventional technologies. And for you that means up to 70% fewer energy costs and CO2 emissions. In addition, the homogeneous flame pattern guarantees even fewer hotspots and thus minimizes the formation of nitrogen oxides. The NOx value is significantly reduced.

Thinking Design.

No question about it: a stunning design makes the OPTIMA plus radiant heater stand out. Yet its design is more than just a pretty face - as you will see, it follows strict functional principles.The outer shell of OPTIMA plus is a closed, fully insulated system. It encloses the burner and radiant tube, ensuring that as little valuable heat as possible escapes upwards.
