The supraSchwank belongs to the top models amongst plaque heaters [also known as luminous heaters] and is renowned for its first-class energy efficiency. This is enabled through the use of optimised materials, its Delta mixing chamber for pre-heating the gas-air mixture, its high-temperature radiation grid as well as the specially developed full insulation. Through the combination of all its properties, heat losses and heat accumulations beneath the ceiling are minimised and the heat arrives from these plaque heaters where it is required – at the workstation.

  • Seasonal energy efficiency of 99.1%*
  • 82,4% radiation factor
  • 95,0% thermal efficiency [with respect to the net calorific value Hi]
  • Full modulating as standard
  • Ceramic full insulation
  • Patented Delta mixing chamber for pre-heating of the gas-air mixture
  • Combined radiation for high radiation factor
  • Uniform and comfortable heat distribution
  • Short heating times
  • Quality, durability and high comfort
  • No dust swirls or draught air
  • Fast and easy installation
  • “Made in Germany” quality

* Calculated according to Directive 2015/1188 of the European Commission on the supraSchwank 30/M plaque heater model

Since 01.01.2018, the ErP Directive has also applied to hall heating systems such as tube heaters. Systems from SCHWANK achieve excellent values here. Find out everything you need to know about the requirements of the new Ecodesign directive below.

Schwank has achieved another milestone in heating control with the standard introduction of the IC 4000 automatic burner control in all heating systems.

From 01.01.2018 Schwank is the first manufacturer to eliminate the 2-stage modulation for all its bright and dark radiators in favour of stepless modulation.

Application reports


Foundries are characterised by unusual spatial conditions, whether new or old. While the casting furnaces produces enormous heat, blowers suck off the polluted air in very large quantities. This is about 30,000 m³/h per hall area.

The BMW Group has set itself the goal of continuously increasing production while maintaining the same level of energy consumption. The so-called energy sustainability index regards the heating system as an essential component of this overall economic efficiency.

The largest Polish steelworks with approx. 4,000 employees and a capacity of 5 million tons per year is located in Katowice. The plant has three blast furnaces, two rolling mills, three continuous steel foundries and its own power plant.
