These boilers come in three ranges – the DP Profi manual boiler, the DPX Profi having the convenience of external cleaning handle and the highest specification, the DPX Lambda which has the ability to monitor the combustion gases, oxygen level and temperature and ensures continual combustion of the boiler for optimum performance and emissions.

The Attack DP Wood Gasifying Boiler range is an economic and eco-friendly method of heating from split logs, designed to cater for heating and domestic hot water.  The boilers are suitable for both residential and commercial applications.  The DP range of boilers is designed to be most efficient when using dry seasoned split logs.

KEY ADVANTAGES:

• Output range

DP Profi                     – 25/35/45/75/95 kW

DPX Profi                  – 25/35/45 kW

DPX Lambda                        – 25/35/75 kW

• Each boiler can vary its output.  DPX Lambda has the ability to monitor the combustion gases and adjust combustion conditions for optimum performance.
• Combustion of hard and soft wood
• Large fuel chamber for longer combustion time from one load
• High efficiency heat exchanger
• High combustion efficiency (up to 91%), low fuel consumption and low emissions
• Simple operation and cleaning
• Automatic shutdown of boiler after fuel burn out
• Combustion fan for continuous and effective operation

• Equipped with a cooling circuit that protects the boiler from overheating
