The Helios EHR‑R 0,8÷125 electric heater is equipped with a closed tubular heating element made from stainless steel, designed to maintain a low surface temperature. The heater is housed in a duct casing made of galvanized sheet steel with an integrated terminal box, suitable for installation in standard commercial duct systems.
Safety is ensured by two temperature limiters: an automatic reset type that activates at 50 °C and a manual reset type that triggers at 120 °C, providing reliable protection against overheating.
