What is the Fröling T4 150?

The Fröling T4 150 is a compact, 4th generation, automatic wood pellet or dry wood chip boiler, designed for maximum efficiency and low emissions. This commercial wood boiler safely burns wood pellets or dry wood chips with a moisture content up to 30%, making it a flexible solution for various commercial heating applications.

Key Features

The Fröling T4 150 is engineered with advanced components that maximize efficiency, reduce emissions, and simplify operation. From intelligent combustion to easy maintenance, each feature is designed to deliver reliable, low-maintenance heating for commercial needs.

Silicon Carbide Combustion Chamber

The silicon carbide combustion chamber delivers intense, efficient heat with ultra-low emissions. Patented firebrick design ensures excellent air sealing without extra seals and makes maintenance simple. Residual embers help auto-reignite fuel after short idle periods, reducing igniter use.

Smart Combustion Control

A negative pressure switch and induced draft fan work together to ensure safe operation. Smart air control adjusts primary and secondary airflow based on combustion conditions. Paired with a standard lambda sensor, this system keeps emissions consistently low.

Variable Speed  Induced Draft Fan

The standard speed-regulated induced draft fan, ensures the exact air quantity and constant under-pressure throughout combustion. By speed regulating, the induced draft fan assists with combustion control and adjusts boiler output. The induced draft fan is also very quiet and energy-saving.

Smart Grate  Technology

The combustion grate is divided in sections to ensure optimal combustion of pellets or wood chips. The tilting grates are built to not only distribute fuel within the combustion chamber, but to pivot vertically to clear ash away. The grates are made of a special high temperature steel alloy to guarantee a long service life.

Easy Ash  Removal

Ash is automatically moved into a sealed ash box by augers powered by a single motor. The system sweeps the chamber thoroughly, and the controller alerts when it’s time to empty. The box rolls easily with wheels and a handle, and a flap prevents spills during transport.

Best Suited For

Schools, small businesses, and light commercial buildings
Facilities using pellets or wood chips (automated fuel feed & ash removal)
Eco-conscious sites needing low emissions and high efficiency (up to 94%)
Low-noise, low-maintenance environments
Clean-air zones

Fröling Discharge System Overview

Built for use in your wood pellet or wood chip silo, the simple and effective design of Fröling's rotary agitator discharge systems ensures smooth operation. Any problematic materials (e.g. foreign debris) are automatically detected and removed by a reverse turn of the augers (turn control). The feed auger with progressive screw blade ensures low energy consumption.

What Our Clients Say About Us

Angela says:

“Happy with our new wood pellet boiler. While it is very expensive to install this boiler, both state and federal rebates may be available. Also, over the long term it is much cheaper to heat with pellets than gas or oil. Froling was great to deal with. Professional, responsive, on time. Definitely recommend Froling and their products.”

Gretchen says:

“Great experience when they installed my residential pellet boiler. All the workers were very respectful, neat and polite. Mark and everyone was so helpful in the process of planning and getting this done, on time, with minimal disruptions.”

FAQs about the Fröling T4 150
