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 heating
elements delivering total power of 1800 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
The unit features two systems for keeping the products hot
while in the hoses:
Recirculation hoses (maximum length 11 metres)
Hose heated by woven elements at 230V fitted with
temperature sensor (maximum length 15 metres)
If longer hoses are required, a standard HI-TECH hose
(maximum length 48 metres) heated by transformer can be
used.
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.
