CHARACTERISTICS
The PH-20/PAX-20 Proportioner has been designed and built for the application of polyurea
chemical systems, polyurethane foam chemical systems and some specific two-component
epoxy systems.
Principal Heating System
The Proportioners consists of two (2) independent Material Heaters without internal seals. The
PH-20 Heater has Three (3) Heating Elements per heater rated at 1,250 watts each giving the
Proportioner a total heat of 7500 watts. The PHX-30 heater also has 3 Heating elements per
heater rated at 1500 watts each giving the proportioner a total heat of 9000 watts. Each heater
has the necessary controls and safety components for their precise operation. The Material
Heater design allows a temperature differential (ΔT) of 58º F and material application
temperatures of up to 190º F.
Hose Heating System
The system is designed with a 2 KVA Isolation Transformer that enables effective heating of
up to a total hose length of 210 feet. The system includes an innovative hose heating concept
in which the continuous braid tinned-copper jacket is distributed evenly around the
circumference of the hose providing a uniform heating watt density and precise control of the
material application temperature. This hose heating element design is extremely resistant to
fatigue failure.
100% circumferential coverage produces the
most uniform distribution of heat available.
Double Acting Piston Metering Pumps
The vertical double acting Pump Line is driven by a Hydraulic Cylinder. The in-line pump
system with vertical piston pumps provides a constant volume and ratio on both the up stroke
and down stroke. .
