The
Easy Spray
proportioning unit has been designed and built for the application of Polyureas,
chemical systems for polyurethane foaming, and some two-component Epoxy systems.
Its reduced size allows easy transport to site. Its easy operation (simply turn one switch and
push the START button) reverts into time saving during set up and application.
Principal Heating System
Consists of two independent heaters without seals. Each heater has two 900 W heating
elements, which give the unit a total power of 1800 W and the necessary control and safety
components for the precise operation of the system. Its peculiar configuration allows a
temperature differential (
ΔT) of 30º C and application temperatures of up to 70º C under normal
conditions of ambient temperature.
Proportioning Pumps
Comprises two positive displacement piston pumps, driven by a pneumatic motor. The system
includes two pressure regulators that allow the working pressures to be equalized in the two
directions of pump movement, compensating for the imbalance of pressure caused by the
difference between the upper and the lower side of the air motor, and the effect of the additional
pressure of the transfer pumps.
