CHARACTERISTICS
The
Classic
PH Series 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 consist of two (2) independent Material Heaters without internal seals. Each
heater for the PH(X)-25 Proportioner has four (4) Heating Elements rated at 1,000, 1,250 or
1,500 watts, each giving the Proportioner a total heat of 8,000, 10,000, or 12,000 watts. Each
heater for the PH(X)-40 Proportioner has six (6) Heating Elements rated at 1,250 1,500 or 1,750
watts each, giving the Proportioner a total heat of 15,000, 18,000 or 21,000 watts. The Material
Heater systems for all PH Series Proportioners contain the necessary control and safety
components for their precise operation. The Material Heater design allows a temperature
differential (ΔT) of 90ºF (32ºC) and material application temperatures of up to 190ºF (88ºC)
under normal ambient temperatures.
HOSE HEATING SYSTEM
The PH(X)-25 Proportioner is designed with a 3 KVA (90 V) Isolation Transformer that enables
effective heating of up to a total hose length of 310 feet (94 meters). The PH(X)-40 Proportioner
is designed with a 5 KVA (120 V) Isolation Transformer that enables effective heating of up to a
total hose length of 410 feet (123 meters). Both systems include 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 OPPOSED PISTON METERING PUMPS
The opposed double acting Pump Line is driven by a dual 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 1:1 to 4:1) between the chemical components used in
the process.
