ErP Directive for fans

The analysis of the ErP (Energy-related Products) directive, with the new standards planned for 2026, highlights a crucial shift: it is no longer just about "consuming less", but about optimizing the entire air movement system.

While previous regulations laid the foundation, the update raises the bar significantly. With the new standards, many fans that previously barely fell within the parameters will result out of compliance.

The European Union aims for climate neutrality by 2050. Since industrial and commercial ventilation systems represent a huge share of European electricity consumption (around 15-20% of industrial consumption), even a 1% increase in fan efficiency translates into gigawatt-hours saved on a continental scale!

The analysis of Tecsystem fans (TTG, TG, and TRBH series) highlights a rigorous approach to quality and safety, with regulatory compliance that extends beyond simple energy efficiency.

1. TTG Series (TTG240, TTG300, TTG360)

The fans in this series are mainly designed for cooling distribution transformers from 100 up to 1250 KVA.

• Energy Specifications: They feature limited power consumption, ranging from a minimum of 31W (TTG240 at 50Hz) to a maximum of 57W (TTG360 at 60Hz).
• ErP Compliance: The ErP Directive generally applies to fans with an electrical input power between 125W and 500kW. Since the entire TTG series remains well below the 125W threshold, these models are technically exempt from the specific minimum efficiency requirements for industrial fans, while still complying with harmonic limits (EN 61000-3-2).
• Other Certifications: They comply with RoHS and WEEE directives for disposal.

2. TG Series (TG180, TG360, TG500)

Higher performance models intended for cooling distribution transformers from 1250 up to 200 and more.

• Energy Specifications: Power consumption is higher compared to the TTG series, ranging from 75W (TG180) to 120W (TG500).
• ErP Compliance: Even in this case, the most powerful model (TG500 at 120W) is below the critical 125W threshold. Therefore, the entire range is not subject to the specific ErP energy efficiency labeling for fans. However, the construction is declared to be "in accordance with CE regulations".
• Environmental Standards: They comply with RoHS requirement.

3. TRBH System (TG180BH, TG360BH, TG500BH)

        Represents the technological evolution of Tecsystem, focused on smart efficiency.

• BLDC Technology: Unlike the standard series, the TRBH system uses electronically controlled motors managed by the NT935BH control unit.
• Efficiency and Savings: Although nominal power ratings remain below 125W (max 95W for the TG500BH), the system fully reflects the "spirit" of the ErP directive thanks to 10-step speed regulation utilizing inverter technology (VSD), based on the actual temperature.
• Green Advantages:
  • Consumption reduction: The system activates the fans only when necessary and at the minimum speed required, increasing overall efficiency.
  • Noise reduction: By optimizing revolutions per minute (RPM), acoustic pollution is reduced.
  • EMC Standards: It complies with EN 61000-3 standards, ensuring low electromagnetic emissions and high efficiency in power control.

Summary of Compliance

In short, Tecsystem fans are not subject to ErP efficiency constraints for industrial fans because they operate at power levels below 125W. However, the company implements innovative technologies (especially in the TRBH series) that exceed standard requirements in terms of smart energy management.
