Basic Information


5th grade pellet boiler – SlimKo MAX

Small size, simplicity of use, and excellent energy efficiency of up to 91%. The SlimKo MAX central heating furnace is a solution that is ideal for heating small office rooms as well as buildings with a huge area. Boilers in the 5th class powered with pellets are available in several power versions to choose from:

  • 70 kW,
  • 90 kW,
  • 120 kW,
  • 150 kW,
  • 300 kW.

Depending on the type selected, they are able to effectively heat an area of ​​about 210 sq m. up to 4,000 sq m The highest quality materials were used for their production – P265GH boiler sheet or high-quality self-cleaning pellet burner. Thanks to this, the construction is solid, it has a long service life, and at the same time it guarantees excellent energy efficiency, which translates into lower heating costs.

We offer a choice of boilers in several versions of the capacity of the fuel container for individual choice:

  • 330 l,
  • 440 l,
  • 660 l,
  • 820 l,
  • 1200 l.

Maintenance-free boiler operation system

By putting on SlimKo MAX, you can free yourself from the tedious operation of the entire central heating boiler control system. All you have to do is top up the fuel feeder. The boiler has a rotary combustion chamber and fuel feeding is a fully automated process here. However, this boiler can be completely maintenance free. It is possible to equip it with an automatic ash removal system. It is poured into an external tank.

To make the operation even more convenient, each furnace is equipped with the latest control electronics. Constant monitoring of the most important operating parameters of the central heating furnace is possible not only from the level of the control panel located on the device itself. The ecoNET300 internet module is also installed there. Thanks to this, the preview of working parameters is additionally available from the computer level. This not only facilitates the operation of the furnace itself, but also speeds up the implementation of the service provided by our company. We can monitor the device on an ongoing basis and make corrections without the need to visit the customer personally.

Bezobsługowy kocioł na pellet 5 klasy – ekologia w najczystszym wydaniu
