Fully Wired Circular Duct Heater – 200Ø – 0.75kW – 1 Phase – 1 Stage

Product Code: AC200-0750FW

The AC200-0750FW Fully Wired Circular Duct Heater is a 200mm diameter, 0.75kW electric duct heater manufactured by Airflow Engineering (SI) Ltd.

Designed for installation within circular duct systems, the heater is supplied fully wired and ready for connection, with the required isolator, fuses, contactor and controls incorporated into the heater assembly.

Airflow circular duct heaters use electric resistance elements mounted within a galvanised steel casing and are designed to provide controlled supplementary heating within HVAC and ventilation systems.

Fully Wired Heater Assembly

This model is supplied as a complete 1-stage heater assembly incorporating:

• Isolator

• Fuses

• Contactor

• High-temperature safety cut-out

• Differential air pressure switch

• Digital temperature controller

The incorporated safety controls help ensure the heater operates only when the required airflow conditions are present and provides protection against excessive temperatures.

This duct heater is manufactured and wired by a registered electrician from Airflow Engineering (SI) Ltd in Christchurch, New Zealand, combining the heater casing, element, controls and electrical components into a complete ready-to-connect assembly.

Why Choose an Airflow Duct Heater?

Airflow duct heaters are a premium heater and are priced accordingly, reflecting the components, controls and safety features incorporated into each unit.

We use robust finned heating elements, together with a differential air pressure switch that monitors airflow and allows the heater to be mounted horizontally or vertically where suitable.

Our fully wired heaters incorporate over-temperature protection, a differential air pressure switch and a digital thermostat, all built into a complete heater assembly.

For us, the priority is a robust, well-controlled duct heater with the appropriate safety features built in.
