The Ps20 is a drum Uploader from Meler. 

It is a melting and pumping system designed to handle thermoplastic materials that uses drum containers with capacities of up to 20 L. The direct use of the material packaging does not require protective systems when using reactive polyurethanes because the only material being pumped is also being melted. This machine integrates the meler control that provides an operator-friendly and efficient motor control.
