Basic Information

PRODUCT DESCRIPTION

The combustion process in our device is controlled by a microprocessor controller.

Functions performed by the controller:

  • fan and screw or piston feeder control
  • central heating pump control
  • hot water pump control
  • floor pump control
  • circulation pump control
  • mixing valve actuator control
  • possibility of connecting a room controller with RS or traditional communication
  • possibility of connecting GSM module
  • possibility of connecting GSM module
  • possibility of controlling two valves by means of additional modules

Design advantages

  1. Designed in 3D CAD SolidWorks technology
  2. Made in CNC technology *crude product of the highest quality P265GH boiler plate laser cut, folded on press brake minimizing welding to the necessary components
  3. Welding using welding beam in MIG technology protected by technical gases
  4. Boiler body made from 6mm sheet
  5. No emergency ceramic inlays − Boiler furnace designed in a way that lowers the emissivity of dust and harmful factors without the use of ceramics.
  6. Boiler cover plates made aesthetically and professionally with attention to detail for everyday use.
  7. Increased thermal insulation of the boiler, for better efficiency reaching 92% mineral wool with a thickness of 50mm.
  8. Insulated boiler floor
  9. The occurrence of point and linear thermal bridges reduced to a minimum
  10. Steel screens catching the largest amount of particles in the early stages of combustion.
  11. Large fuel tank sufficient for a few days
  12. Cover plates securing the feed system and the fan
  13. Ease of use involving the periodic removal of ash from the bottom of the drawer and cleaning the convection channels
  14. Boiler tray can be adapted to the right or left side depending on the order
  15. Boiler fuel provided through a retort system from Pancerpol
  16. The device can be mounted in a closed system
  17. 5 year warranty
