Charging Boilers

KDR Plus 3

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 lata gwarancji na szczelność wymiennika ciepła, 2 lata na pozostałe elementy i sprawne działanie kotła. 4 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler.
wymiennik ciepła wykonany z atestowanej stali kotłowej /gat. P265GH/ o grubości 6mm heat exchanger made of certified boiler steel
 elektroniczna regulacja kotła z obsługą dwóch pomp oraz algorytmem
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;
sprawność high thermal efficiency reaching 82,2-83% thanks to increase heat recovery from flue gases
w wersji do układu zamkniętego jako KDR 2 NZ in version for closed system as KDR 3 NZ*
duża komora spalania Large combustion chamber
wielopunktowy system doprowadzania poiwetrza w strefę załadowanego paliwa multi-point air supply system to the fuel charging zone
szeroki zakres mocy wide range or power
