Mobile district heating station

When you need to heat large spaces, like construction sites or industrial halls, in harsh winter conditions, TFUC is the solution you need. This powerful machine can transfer up to 1.6 mega watts of heat from the district heating to your local area, and offers remote control, monitoring, and fine-tuning of parameters via a LoRaWAN network for efficient heating.

El-Björn, a Swedish company specializing in industrial-grade HVAC equipment, presented TFUC – a state-of-the-art central controller unit developed by Byte Lab.

This innovative system seamlessly integrates with district heating, allowing for efficient transfer of heat to the local area. Equipped with powerful pumps, valves, heat exchangers, and a multitude of temperature and pressure sensors, TFUC ensures optimal temperature control with ease.

The user-friendly graphical display, alarm management, remote access and monitoring capabilities, and convenient firmware updates through the LoRaWAN network, make operating TFUC a breeze. And with cloud-based control and monitoring capabilities, each TFUC unit can be managed from anywhere at any time.

Byte Lab was in charge of creating the central controller unit, seamlessly integrating it into the larger heating system.

With the aim of maximizing efficiency, complex firmware and rugged industrial-grade hardware were devised. The team delved into the mathematics of the heating system to gain a comprehensive understanding and develop a reliable solution for control. The intuitive graphical user interface allows for on-site fine-tuning and control, while real-time monitoring and alarm checks are just a few clicks away. The controller units communicate with a secure LoRaWAN gateway, connecting to the cloud server for remote monitoring, control, and firmware updates. A custom LoRaWAN antenna was specifically designed to integrate effortlessly into the controller’s enclosure.

Despite not having physical access to the complete TFUC system, Byte Lab utilized a combination of firmware separation and mathematical simulations to develop and test the firmware with precision. Remote debugging techniques were employed for thorough fine-tuning and optimization of the complete heating system.

After development was complete, TFUC modules were produced and shipped to El-Björn, where they were installed into the system. Today, TFUC is commercially available and distributed by El-Björn.
