The
evolution G-30 H
metering unit has been designed and built for the application of
Polyureas, chemical systems for polyurethane foaming and some two-component epoxy
systems.
Principal Heating System
Consists of two independent heaters without seals. Each heater has four 1500 W heating
elements, that give the unit a total power of 6000 W, and the necessary control and safety
components for precise operation of the system. Its singular configuration allows a temperature
differential (
ΔT) of 90º F and application temperatures of up to 194º F under normal conditions
of ambient temperature.
Hose Heating System
Designed with a 3000 W isolation transformer that
enables effective heating up to a total hose length of
305 ft for foam and 256 ft for polyurea. The system
includes an innovative hose heating concept in which
the copper heating element is spread evenly around the
circumference of the hose, providing a uniform heating
watt density and precise control of the product
application temperature. This hose heating element
design is extremely resistant to fatigue failure.
100% circumferential coverage produces the most homogenous distribution of heat available.
Double Acting Opposed Piston Metering Pumps
A pump line driven by a double rod hydraulic cylinder. The in line pump system with opposed
piston pumps provides a constant volume and guarantees uniform pressures in both directions
of pump movement. Different sized pumps allow for various volumetric ratios to be achieved
(1:4 to 4:1) between the chemical components used in the process.
