The press-forge polyamide items have to undergo a humidification process in order to find their design features of elasticity and resistance. PGV projected FUN 9001/9002 allow a controlled humidification treatment in order to restore the item best condition and then use it immediately. Il FUN composed of a metallic structure, with internal stainless steel sealed chamber, thermally insulated. Inside the structure there are the heating systems by armoured electric resistors and a system for forced-circulation of air. Motor driven dampers allow the air inlet/exhaust in and out the furnace. The closing door is provided with a safety device which unlocks only when the inside temperature is not so high to harm the operator.
 

The humidification process is composed of three steps: the first is the material pre-heating in order to increase its porosity; the second is humidification, during which humidity is absorbed by the item which is kept in preset thermo-hygrometric conditions; the third is the drying and cooling of the item, mainly performed for aesthetic purposes, to obtain an item with a dry surface. 

The loading system consists of European standard platforms capable to carry containers, possibly made of stainless steel, drilled both on their sides and their bottom in order to enable the forced-circulation of steam. A footboard makes the introduction of containers in the furnace easier.
