D Series = Oil Fired | DG Series = Gas Fired
The “D & DG” include a low stress thermal shock resistant single pass vertical design. With thousands of boilers installed worldwide this has proven to be a robust boiler design.
Primary flue gases pass via water backed heat transfer tubes. No refractory backed finned passages to burn out.
Large steam chamber with internal water separator insures high quality dry steam.
The“D & DG”Series may be factory constructed with an integral copper finned heat exchanger allowing the boiler the ability to provide both direct heating and indirect heating.
