The Helios EHR‑R 6/250 is a closed tubular electric heater designed for use in standard commercial duct systems. It features a stainless steel heating element engineered for low surface temperature operation, making it a safe and effective solution for controlled air heating.
The heater is housed in a galvanized sheet steel duct casing with an integrated terminal box for straightforward installation. To ensure safe operation, it includes two thermal protection devices: an automatically resetting temperature limiter that activates at 50 °C and a manually resettable limiter triggered at 120 °C.
Ideal for reliable temperature control in ventilation systems, the EHR‑R 6/250 combines robust construction with advanced safety features for long-term performance.
