MBT's new flammable refrigerant multi-split system series achieved TÜV SÜD's first triple safety certification at MCE 2026 in Milan, demonstrating compliance with international safety standards. Key representatives, including MBT Director of Product Management Jesse Hong and TÜV SÜD Global Industry Segment Leader Robert Ostendorf, attended the presentation. The certification confirms adherence to safety requirements for system integrity, ingress protection, and component durability. This milestone supports the deployment of environmentally friendly refrigerants in HVAC applications.

Background

The HVAC industry is transitioning to low-global warming potential (GWP) flammable refrigerants in response to environmental targets and regulatory mandates. These refrigerants require advanced safety strategies to address leakage and ignition hazards. MBT introduced the "Triple Safety Protection" design, commissioning TÜV SÜD to verify compliance across essential safety criteria at MCE 2026, a leading global HVAC event.

Details

TÜV SÜD's certification encompasses three technical areas:

  • Intrinsic safety, evaluated to EN 60335-1:2012/A16:2023 and EN IEC 60335-2-40:2024/A11:2024
  • Ingress protection to IEC 60529 standards, including IP55 (dust-tight, water jet protection) and IP68 (resistance to immersion)
  • Component robustness under simulated fault conditions

Testing verified effective control of refrigerant leakage and ignition risks. Components maintained performance in adverse environments. TÜV SÜD issued certificates reflecting conformity with EU harmonisation standards for flammable refrigerant systems.

MBT and TÜV SÜD highlighted the certification's technical basis at the MCE 2026 exhibition. Messaging prioritized safety in low-GWP refrigerant use. MBT's multi-split systems offer both environmental benefit and third-party verified safety and durability.

Outlook

The certification is positioned to facilitate the adoption of low-GWP flammable refrigerants among fleet operators, OEMs, and retrofit projects in HVAC and transport refrigeration. MBT's certified safety framework may inform industry best practices and support broader regulatory approval throughout European markets.
