This thyristor controlled electric post heater is designed for seamless integration with compatible heat recovery units to provide accurate supply air temperature control. Installed within circular ventilation ductwork, it works alongside an air handling unit controller to maintain the required supply air temperature, improving comfort and supporting efficient ventilation performance.
Constructed from galvanised steel with stainless steel heating elements, the heater is built for reliable long-term operation. A 20mm non-flammable mineral wool insulation layer reduces heat loss, while airtight rubber seals help maintain ventilation system efficiency.
Designed for use with compatible heat recovery units, this electric post heater is supplied as a complete kit for straightforward installation. Integrated controls and safety features provide dependable operation while enabling precise temperature regulation.
Thyristor control enables accurate regulation of the supply air temperature by working directly with the air handling unit controller. This helps maintain comfortable indoor conditions while ensuring the ventilation system responds efficiently to changing heating demands.
The insulated galvanised steel construction, stainless steel heating elements and airtight duct connections provide reliable performance and long service life. Integrated overheat protection enhances operational safety for professional ventilation installations.
Suitable for installation within circular duct ventilation systems connected to compatible heat recovery units, this electric post heater is designed for residential and commercial mechanical ventilation applications requiring controlled supply air heating.
The heater can be mounted in various positions using the supplied clamps. Airflow must follow the direction indicated on the heater casing. When mounted horizontally, the control box should be installed with the cover facing upwards and may be rotated up to 90° from its normal position. The control box must not be installed with the cover facing downwards.
The heater connects directly to the air handling unit controller using the supplied power and signal cables. Correct installation and controller integration are essential to ensure accurate temperature control and safe operation.
