nVent Hoffman: New Industrial Air-to-Air Indoor Heat Exchangers

September 8, 2026
Introducing Air-to-Air Indoor Heat Exchangers, a compact, efficient, and cost-effective solution for cooling electrical switchboards inside industrial cabinets.
The MIX range protects temperature-sensitive components from thermal shock when external temperatures are lower than internal ones. With cooling capacities from 12 to 44 W/°F, the MIX range provides flexible solutions for a wide range of indoor industrial applications. The heat exchangers feature countercurrent airflow and optimized heat-transfer surfaces, delivering reliable thermal performance.
Units can be installed inside or outside the cabinet, with rear or side electrical exits for installation flexibility. An advanced coil design helps prevent clogging, maintain high efficiency, and reduce maintenance. Fans and coils can be removed quickly and safely when service is required.
The series is Type 12 and IP54 rated for indoor use to protect against contaminants and UL listed to meet applicable safety standards.
