All those polyurethane moulders using low pressure foam technology, with the need to fully eliminate the problem for solvent disposal, and showing great attention to environmental problems in the respect standards / in force, may rely on this new generation of high pressure metering machines combining first-rate characteristics.

THERMOREGULATION MODULE

· Stainless steel tube-nest heat exchangers for constant control of temperature, with cooling water on/off valve and IP 55 band armoured resistance.

POLYOL/ISOCYANATE METERING MODULE

The high-pressure metering module has been conceived and carried out to satisfy the needs of easy maintenance and reliability

Each unit comprises:

· High accuracy volumetric flow meter.
· Direct-reading sensor for output control.
· High-pressure, gear pump, of high accuracy with changeable delivery, and 300 bar max working pressure. It is coupled to 3-phase asynchronous motor via mechanical coupling.
· Digital pressure gauge, with two independent contacts and/or analogical signal, and setting of min/max working pressures.
· Electro-pneumatic valve OMAL to operate the low/high pressure recycle.
· Flow valve for tanks/mixing head recycle.

HIGH PRESSURE, "EKS" MIXING HEAD

The mixing head is "the heart" of every polyurethane production system. Using its extensive experience got in the specific field Ekosystem has projected and developed a new L-shaped damped flow high pressure, "EKS" mixing head carefully conceived to ensure three basic principles: user-friendly operation, compactness and homogenous mixing of the components.
A 3kw hydraulic pack type CX-40/PAM drives the mixing head. This pack is equipped with a 40l capacity oil storage tank and a heat exchanger for oil thermoregulation.

MACHINE CONTROL MODULE

The electrical panel with IP55 protection is sited at the base of metering module, and incorporates the technology of the machine.
All the machine cycles are processed by:
· Siemens Simatic S7 PLC for sequential control of functions, temperatures, pressures, timers, counters, and processing analogical functions.
· Vectorial inverter to control and handle the motors, connected to metering pumps and interfaced to the PLC.
· Graphic operator board with integrated keyboard and display, type "touch-screen 7", to set and control all the machine parameters.
· Control push buttons panel located on board of mixing head with: pouring start/stop controls, buttons for pouring cycles choice, and display visualising cycle number and pouring seconds.

OPTIONS

· Independent POL/ISO storage jacketed tanks group.
· Automatic loading system.
· Automatic system for outputs self-adjustment.
· Chiller unit to check the temperatures.

MAIN BENEFITS FOR CUSTOMER

1) Power saving
2) Reduced space thanks to small dimensions of frame
3) Possibility of direct connection to components drums or tankers by special pumps without needing pressurised tanks.
