The Helios EHR‑K 30÷60÷30−35 is a high-performance electric heater battery designed for installation in rectangular ventilation ducting. It features enclosed tubular heating elements with a low surface temperature, wired to an external terminal box for connection and grouped operation control.
The housing is constructed from durable galvanized sheet steel and includes flanges on both ends, enabling secure and straightforward integration into duct systems. The unit is equipped with two safety features: an automatic reset thermal cut-out that activates at 90 °C and a manual reset temperature limiter that triggers at 120 °C, ensuring safe and reliable operation in air handling systems.
