Pellet steam boiler PRN/PD

Two-pass flame and smoke tube boiler with a semi-wet back chamber

  • Capacity :  100 ÷ 2.000 kg/h
  • Design Pressure : 0,5 ÷ 16 bar

Steam boilers type PRN / PD are suitable for pellet fuel burning with burners from well known European houses.

PELLET

  • The use of pellet compared with conventional fuels - oil, natural gas - means that the economy may be over 50% of the total costs of heating and hot water.
  • 100% natural product without chemical additives, it is dry and leaves no ash. A bag with 15 kilos of pellet will leave only 75 gr of ash!
  • Efficiencyexceeding 92% ensurescredibilityandgreatereconomyinconsumption  compared to other boilers in the market

PRN / PD boilers are constructed and tested in accordance with the P.E.D 2014/68/EUrelative to the pressure equipment (PED)

  • Simple in use
