ZMH Šukoplam PR – Log Boiler 20kW (68,240 BTU) PR Fan Assisted

ZMH Šukoplam PR – Fan Assisted Log Boiler (20–80 kW)

The Šukoplam PR is a high-performance fan-assisted solid fuel log boiler, available in outputs from 20 kW to 80 kW, designed for applications requiring precise temperature control and reliable combustion performance. Suitable for burning solid piece fuels, this boiler utilises an artificial draft combustion fan, making it ideal for industrial, commercial, and specialist heating processes.

Based on the proven Šukoplam R boiler range, the PR model incorporates a combustion fan mounted on the lower door, allowing the boiler to operate independently of natural chimney draft. Combustion air is supplied primarily by the fan rather than chimney traction, ensuring stable combustion, improved efficiency, and consistent water temperature control.

The fan-assisted system enables reliable operation even with chimneys of limited height or diameter, where natural draft would normally be insufficient. Automatic boiler controls regulate both fan speed and combustion air supply, maintaining the set water temperature within narrow limits—an essential requirement for many process and industrial heating applications.

Due to the increased draft generated by the combustion fan, the boiler is equipped with turbulators in the flue gas tubes, converting laminar flow into turbulent flow. This significantly enhances heat transfer between flue gases and boiler water, increasing overall efficiency by approximately 7–10%, resulting in reduced fuel consumption.

The Šukoplam PR is constructed as a three-pass hot water boiler, featuring a water-cooled partition and pipe bundle, ensuring maximum heat extraction as combustion gases pass through the water jacket three times. The boiler body is insulated with mineral wool, and the outer casing is protected by a plasticised finish for durability and corrosion resistance.

The boiler supports operating temperature regimes of 110/90 °C and 90/70 °C, with a maximum operating pressure of 2.5 bar. Safety is ensured through the installation of a pressure relief safety valve and a thermal safety heat exchanger, which automatically cools the boiler in the event of overheating.
