Home arrow 24h fine coal-fired boilers

KWM-S, KWM-SG type fine coal-fired boilers
with a controller and blower - operating 24 hours

The use of fine coal provides efficiency up to 86%
The use of fine coal provides efficiency up to 86% After firing up a boiler there is no need of permanent operation - 24h combustion These boilers are characterized by slight influence on the environmental pollution. The maintenance costs are low due to complete combustion of fine coal and combustible gases Combustion process is regulated by a microprocessor controller
Safe maintenance

KWM-S (SG) type boilers are designed for heating up water in the central heating system to a temperature not exceeding 90°C at the boiler outlet. They may be applied for heating residential buildings, commercial and production facilities, workshops, farms, greenhouses, schools, etc.
Currently these boilers are the most modern and innovative type of solid fuel boilers produced in Poland, and are incomparable with any other boilers in the same range. KWM-S type boilers have an ecological certificate and were granted declaration of conformity in accordance with energy efficiency requirements. Emission and energy tests were conducted by:

  • Institute of Heating and Sanitary Technology in £ód¼, Poland
  • Institute for Chemical Processing of Coal in Zabrze, Poland

They have a registered utility model certificate No. 57550 and are legally protected.
Characteristic features of KWM-SG type boilers.

  • Easy maintenance, especially the process of cleaning,
  • Increased life-span ,
  • Due to its height, less area is occupied by the boiler in the boiler room.
