Pfannenberg will use SPS 2026 in Nuremberg to preview new cooling technology for electrical enclosures, together with an expanded range of signaling and cabinet safety products. In addition, the German manufacturer will show updated digital tools that help engineers plan thermal and signaling applications before installation. The fair runs from November 24 to 26, 2026.
The company splits its presence across two halls. Thermal Solutions for Enclosures and Machines are in Hall 3C, Booth 250. Signaling & Safety Solutions, on the other hand, are in Hall 4, Booth 300.
Next generation of enclosure cooling
On the thermal side, Pfannenberg will give visitors an early look at new cooling unit developments. It will also preview its Next Generation Filterfans. This is notable because the company invented the Filterfan® in 1958, and the product is still a reference for enclosure ventilation. However, Pfannenberg has not yet published technical data for the new units. Full details will only be revealed at the show.
The updated Green Series portfolio is also on display. With it, customers can choose the refrigerant technology that best suits each application. As a result, panel builders can weigh performance, safety and regulatory requirements case by case, instead of accepting a single refrigerant for every project.
IO-Link signaling and functional safety
The Signaling & Safety booth focuses on three topics:
- IO-Link signaling: signaling devices that integrate into IO-Link architectures for simpler configuration and diagnostics.
- Functional Safety: solutions aimed at improving machine safety.
- Digital 3D-Coverage planning: a tool to plan where signaling devices must go so that alarms reach the whole area.
New: leak detection and fire extinguishing for cabinets
For the first time, Pfannenberg will present Cabinet Refrigerant Leak Detection Systems and Cabinet Fire Extinguishing Systems. Both products extend its safety offer into the enclosure itself. Their purpose is to detect critical risks inside electrical cabinets and respond to them early.
In fact, these two launches fit together with the refrigerant choice in the Green Series. Once a cooling unit uses a different refrigerant, a leak inside the cabinet becomes a safety question. Pfannenberg now covers cooling, monitoring and fire response from one supplier.
Thermal and Signaling PSS 2.0 software
Visitors can also test the next generation of Pfannenberg’s digital planning and configuration tools. The highlight is the new Thermal and Signaling PSS 2.0 software. According to the company, these tools help customers evaluate application requirements, configure suitable solutions and simplify planning before installation.
“We are here to make a complex world simpler and to be a partner you can count on long after the exhibition,” said Dr. Tobias Merl, CEO of Pfannenberg.
Why it matters for machine builders
Refrigerant rules for cooling units are tightening in Europe, as our report on the EU F-gas regulation and enclosure cooling explains. Therefore, a flexible refrigerant choice, combined with leak detection inside the cabinet, can help OEMs keep cooling designs compliant without major redesigns. Meanwhile, IO-Link signaling reduces wiring effort and gives the PLC direct access to device status. Finally, planning software such as PSS 2.0 helps engineers size cooling and place beacons correctly at the design stage, when changes still cost little.
Engineers who want to compare options can book a meeting with Pfannenberg’s experts at the booths. More news from the company will appear in our Pfannenberg section, and further product information is available on the official Pfannenberg website.
