The Helios EHR‑R 9/355 TR is a closed tubular heating element constructed from stainless steel, designed for installation in commercially available duct systems. It operates at a low surface temperature, ensuring safe and reliable performance in air heating applications.
The unit is housed in a galvanized sheet steel duct casing and includes a terminal box for easy electrical connection. Integrated temperature control allows for precise heat regulation, while built-in safety is provided by an automatically resetting temperature limiter (triggered at 50 °C) and a manually resettable limiter (triggered at 120 °C).
Engineered for durability, efficiency, and safety, the EHR‑R 9/355 TR is an ideal heating solution for controlled ventilation environments.
