Elta Circular Electric Heater with Control

Circular Electric Heater with Control The EKA circular electric duct heater is designed to heat fresh air in ventilation systems where accurate temperature control is required. It is built for inline duct installation with an integrated controller option, giving you a neat all in one solution for supply air heating plus preheating in commercial ventilation setups. Why this heater is a strong choice for controlled duct heating Purpose built for ventilation: designed to heat clean air in ducted systems for heating plus preheating duties Integrated control options: multiple control types depending on model, including onboard setpoint control plus remote control inputs Stable temperature regulation: PID based control with triac switching for smooth, quiet regulation without moving parts Safe operation features: dual overheat protection thermostats fitted as standard Durable materials: Aluzinc coated steel casing with rubber duct seals plus stainless steel heating element tube (AISI 304) Air tightness focus: rated to Air Tightness Class D to EN 15727 Control types explained in plain English NV: temperature setpoint potentiometer on the heater lid NI: wired remote setpoint knob for temperature control NIS: external 0 to 10 VDC signal input for control ESKM: external PWM on off signal input (ON 6 to 24 VDC) for temperature control Safety and built in protection Two overheat thermostats: automatic reset at 50°C plus manual reset at 100°C Maximum outlet temperature: 50°C Minimum airflow requirement: air velocity through the heater must be at least 1.5 m/s Installation notes that matter Mounting position: horizontal mounting is permitted with the connection box facing upwards or sideways, not downward Vertical mounting: permitted only where airflow direction is upwards Indoor use only: intended for internal installation and clean air heating only Site suitability: not suitable for explosive or aggressive environments Electrical installation: must be wired by a competent electrician and the heater must be earthed Range overview EKA heaters are available across multiple duct diameters with a broad kW range and supply options depending on model. For accurate selection, match duct diameter first, then confirm minimum airflow, supply voltage and required heating power using the technical data tables. Selection tip Start with the duct diameter, confirm your available power supply, then choose the control type that fits your project. If you are using a remote temperature sensor, the guidance recommends positioning the supply air sensor at a distance of 3 times the heater diameter from the heater.
