The easy spray-H
proportioning unit is designed for the application of polyurea chemical
systems for polyurethane foaming and certain two-component epoxy systems.
Principal heating system
Consists of two independent heaters without gaskets. Each heater has two 900 W/1500 W
heating elements delivering total power of 1800 W / 3000 W, and the necessary control and
safety mechanisms for the correct operation of the system. Their special configuration permits a
temperature differential
(ΔT) of 30º C and application temperatures of 80ºC under normal
ambient temperature conditions.
Hose heating system
Designed with a 3000 W isolation transformer that enables effective heating up to a total hose
length of 93 meters (305 ft) for foam and 78 meters (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.
Proportioning pumps
This assembly comprises two positive-displacement piston pumps operated by a dual-piston
hydraulic cylinder.
The parallel piston pump configuration ensures constant volume and guarantees uniformity of
pressure in both directions of pump movement.
