K series boilers (manual loading)

Automated maintenance of the preset temperatures
Preheated primary and secondary air are supplied into the combustion chamber. Even cooling of the boiler walls protects boiler’s heat exchanger from overheating
Balanced water flow in the heat exchanger protects it from overheating and residue
Efficient combustion is achieved by correct rate between the heat resistant concrete and heat exchanging surfaces. Primary and secondary air fans are separate
Turbulators increase efficiency of the heat exchange
Large loading and servicing doors
Boilers are more efficient when installed with an exhauster which is controlled by a frequency adjuster depending on draught
Right and left hand side door opening is available
Environmental parameters conform to EU requirements
Boiler insulation shielding is painted in a high quality powder coat
