PU foaming machine
High pressure foam dispensing machine
The high pressure foam dispensing machine provides the components
accurate conditioning, metering, mixing and pouring. The process
parameters such as the components flow rate are closed loop
controlled and are manage by an industrial personal computer.

insulated, having a capacity of 250 liters, electronic visual level
control for automatic loading, loading gear pump ( for tank loading
from IBC ), PT 100 probe for temperature control, stainless steel
tube nest heat exchanger on recycle circuit of components and plate
heat exchanger complete of conditioning unit on component feeding
line.
Volumetric gear pump for components feeding to the metering high
pressure pump, coupled with electric 3 phase motor controlled by
inverter and complete of cartridge filter. Control of feeding
pressure with electronic transducer. MDI line complete of cables,
electric connections, rigid and flexible hoses and various
accessories. Gear pump for tank loading (120 l/min).
- Polyol line complete of double wall carbon steel tank externally
insulated, having a capacity of 250 liters, electronic visual level
control for automatic loading, loading gear pump (for tank loading
from IBC), PT 100 probe for temperature control, stainless steel
tube nest heat exchanger on recycle circuit of components and plate
heat exchanger complete of conditioning unit on component feeding
line. Volumetric gear pump for components feeding to the metering
high pressure pump, coupled with electric 3-phase motor controlled
by inverter and complete of cartridge filter. Control of feeding
pressure with electronic transducer. Polyol line complete of
cables, electric connections, rigid and flexible hoses and various
accessories. Gear pump for tank loading (120 l/min).
- Catalyst line complete of stainless steel tank, having a capacity
of 30 litres, electronic visual level control for automatic
loading, pneumatic loading pump for tank loading from IBC.
Volumetric gear pump for component coupled with electric 3-phase
motor controlled by inverter and complete of cartridge filter.
Output control with mass flow meter. Feeding pressure control with
electronic transducer. Catalyst line complete of cables, electric
connections, rigid and flexible hoses and various accessories.
- Pre-mixing device for Polyol with Catalyst composed as follows:
- A.C. three-phases electric motor controlled by inverter
- Motor/mixing chamber coupling by means of magnetic joint
This device is complete with electric cables, wiring connections
and hydraulic pipelines and related accessories.
- Water cooler unit ( for components temperature control )
Its function is to supply conditioning water in close loop at
constant output and temperature to allow self-adjustment of Polyol
and Isocyanate machine working temperature.
