GL Dryers are conceived for the treatment of granulate thermoplastic materials which need a superficial removal of humidity by means of hot air forced circulation. GL Dryers up to a 75lt capacity can be directly installed on machine tools; higher capacity models are supplied with supports provided with wheels. All the series of driers is arranged to be equipped with PGV loaders, for the granulate non-stop load. All the dryers have the surfaces in contact with the granulate made of stainless steel and are thermally insulated; furthermore, they are provided with filter on the air inlet and exhaust. The cleaning and replacement are easy thanks to practical unhooking systems.

For the drying of hygroscopic thermoplastic materials, PGV has manufactured the DEU series of drying systems by dehumidified air. These devices exploit the principle based upon water absorption by means to specific materials: this solution enables to obtain air having a DEW POINT lower than –40°C. DEUAS model is fit for a centralized dehumidification system, by connection of GL series dryers. This equipment is very flexible because it allows to connect GL with different capacities that can work at independent temperatures and therefore can treat different materials. These models are equipped with a continuous regeneration rotating drum absorbing system.

DEUM and DEUGL models are monoblock dehumidifying systems, to be positioned near the machine tools, with a self-regenerating cartridge dehumidifying system. DEUM system differs from DEUGL system because it has a built-in loading system to the machine tool, and the plastic granulate is always in a dry air environment.
