Fröling PT4e – Eco-friendly and efficient pellet boiler

Among energy-efficient heating solutions, the Fröling PT4e pellet boiler stands out by combining energy efficiency with environmental friendliness. This boiler is ideal for both new constructions and buildings in need of renovation, offering automatic operation and heating power ranging from 120 to 250 kW. Equipped with pellet vacuum feeding technology, it ensures continuous and effective operation at all times.

Advanced technology and efficient combustion process

The Fröling PT4e pellet boiler is equipped with multiple intelligent technological solutions that make its heating process seamless and economical. Its combustion chamber is lined with silicon carbide walls, known for their exceptional durability and thermal conductivity. Combustion efficiency is enhanced by a two-part alloyed combustion grate, allowing for automatic wood pellet burning. The boiler also features a ceramic igniter, ensuring fast and reliable ignition.

Efficient heat exchange and automatic cleaning

The boiler utilizes a three-pass heat exchanger with a fully automatic cleaning system. This system cleans the heat exchanger in the second and third passes, maintaining the device’s efficiency and ensuring long-term reliability. Additionally, the cleaning mechanism is located in the “cold” section of the boiler, reducing wear and extending the lifespan of the device.

Automatic ash removal and low emissions

The PT4e pellet boiler offers additional convenience with its automatic ash removal system. Ash from the burner and heat exchanger is automatically transferred to a 75-liter ash container, depending on the model. This feature allows for extended operating periods without frequent maintenance. The boiler also includes a high-tech EC draft fan and flue gas recirculation (FGR), which reduce emissions and maximize efficiency.

Intelligent Control System – H 3200 Touch

The boiler's operation is made convenient by the modern microprocessor-based H 3200 Touch control system. This system optimizes the combustion process and precisely regulates boiler and exhaust gas temperatures according to requirements. It can be expanded to manage up to 18 different heating circuits and supports various additional functions, such as integrating solar, oil, and gas boilers. The H 3200 Touch system includes a 7-inch color display, making monitoring and adjustments user-friendly.

Eco-friendly and convenient solution

The Fröling PT4e uses A1-class wood pellets—a renewable fuel that significantly reduces the carbon footprint. Its automatic cleaning and ignition systems make it an excellent choice for those seeking an eco-friendly heating solution with low maintenance requirements. This simplifies daily operation and saves time.
