Batch Heating Hot at Nozzle

When configured so the deicer has built-in purpose designed fuel combustion heating sources - with an extremely high efficiency. This means that the fluid's maximum temperature in the ordinary case will be reached within 20 to 40 minutes - dependent on the heater capacity, tank volume, and initial temperature.

BATCH HEATING considerably shortens the time required for obtaining hot fluid - ready for the de-icing.

The batch tank is a smaller section within the main tank. The content of the batch tank section will be heated first - in order to reach spraying temperature within a very short time. This will automatically open a valve to the larger tank section the content of which consecutively will be heated.

HOT AT NOZZLE ensures hot fluid present out of the spray nozzle by gently circulating fluid in external lines.

This option is available for systems with pre-mixed fluids and onboard mixing systems, and prevents spillage of ineffectively cold and expensive AFD.
