PD series boilers are, blowing burner,cast iron sectioned, between the capacities 29.1 – 78.5 kW with proper burner connection, works with gas or liquid fuel in 6 different ( 3 – 8 sections) type. PD series boilers operating pressure is 3 bar maximum, and working temperature is 90 °C maximum.

In PD series boilers, heat transfer surface areas are increased by the special wings in the burning room and chimney ways. This increases the high heat transfer ability of cast iron boiler to the maximum level. PD series boilers are cast iron sectioned boilers. This brings easy assembling and easy capacity increasing by adding sections to the boiler. The transportation and set up of the boiler is easy because boiler is assembled in boiler rooms It is easily to carry or shift position without breaking walls.

PD series boilers are casted with special alloy, which is durable for heat extensions and changes, EN GJL200. They are long life boilers according to this special cast iron alloy. With the help of vertical and three pass specially designed sections burning gases pass three times in the boiler and transmits burning energy to the water inside the sections at high level.

PD series boilers are high efficiency boilers. ( According to the fuel bottom heating value % 91 – 93 ). With this high efficiency and perfect isolation more energy is gained with less fuel. Heat loses are minimized on PD series boilers. By appropriate burning room, heat transfer surface, turbulator, collector and isolation high heat transfer and optimum flue gas emition results are provided.

Boiler sections are delivered as assembled or not assembled according to the boiler room specifications and dimensions. In unassembled deliveries, sections and assembling apparats are delivered on a pallet where cabins, isolation and other elements are delivered in a box.
