GF-ELTI Controlled Cooling Stations are passive chambers used for the forced and controlled cooling of hot products.
These systems are absolutely necessary to carry out those heat treatments requiring the observance of a specific cooling gradient or, more in general, whenever products must be cooled by forced air.
Stations typically consist of a chamber and a load door; the hot products to be cooled down are placed inside the chamber. In case of high process temperatures, the walls of the Cooling Station can be lined by an insulating layer.
The station is characterised by the presence of an internal ventilation system, by virtue of which one or more electro-fans direct forced air from the bottom upwards by means of pipelines and deflectors cooling down products by convective exchange. The hot air - heated by the heat exchange - can be collected and conveyed to a discharge point or drained in the environment, according to installation conditions.
The charge rests on special support stands, properly realised to maximise the air flow and the resulting heat exchange.
The process is feedback-guided by a regulator connected with one or more process thermocouples that act according to the desired temperature profile and the measured temperature by varying the air flow rate to be blown into.
Types of treated products: products of various dimensions, weight and shape.
