Polyurethane foam injection machine LPE series

for refrigeratorsfor the automotive industryfor insulation panels

The new polyurethane low pressure systems series LPE are made to dose and mix bi-component polyurethane foams. Beyond being compact and aesthetically pleasant, they have been designed to give the user the maximum reliability, safety and simplicity of use. The LPE systems are built on a very strong casing. Special attention was given to the arm structure that supports the chemical lines because of the enormous stress that suffers during lateral and vertical movements (weakness of traditional systems). A push button panel was placed on the mixing head to facilitate its movement. In this system, high performance and very silent brushless motors are assembled. They are specially designed for the operators who have to remain several hours closed to the equipment. In fact, during the foaming procedure, it is hard to hear their noise; the quietness of this system is one of the features that operators appreciate of this machine. The presence of the pumps inside the tanks avoid the possibilityof leakages with obvious consequences of dirt and locking no typeof maintenance or replacement of seals is required.The tanks are supplied with an air-casing for heating/cooling andare equipped with external insulation.They are heated by electric resistances placed under the tanks, whereas for cooling it is advisable to install exchangers in whichcool water supplied by a chiller (optional) runs.The whole process of the machine is operated and controlled bya powerful microprocessor (PLC). A touch screen display is assembled on the console framework and another one on themixing head; on both it is possible to set or recall all desired datafor the correct use /check of the system.
