DESCRIPTION

KDR Plus 3 boilers are based on KDR boilers and additionally equipped with electronic system controlling air blowing for the combustion purposes. Boilers are adapted for combustion of solid fuels, especially wood in form of chunks, and large combustion chamber allows several-hour operation of the equipment. Boilers are operating using forced draught and amount of air necessary for combustion process is controlled using electronic controlled based on PID algorithm maintaining boiler temperature on the same level. Use of multi-point method for supplying of air to the fuel combustion zone increases efficiency of boiler operation and ensured uniform and long-term combustion with stabilization of this process. Heat exchanger of boilers is made of certified boiler steel of thickness 6mm and insulated with mineral wool to limit heat losses

	4 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler.
	Heat exchanger made of certified high-grade boiler steel;
	electronic control of boiler: S3P controller servicing 2 pumps /central heating and hot utility water/ and PID algorithm maintaining constant boiler temperature; adjustable below the control panel;
	high thermal efficiency reaching 82,2-83% thanks to increase heat recovery from flue gases
	in version for closed system as KDR 3 NZ*
	Large combustion chamber
	multi-point air supply system to the fuel charging zone
	wide range or power
