CHARACTERISTICS
The 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 Proportioner consists of one (1) Material Heater without internal seals. The Heater
has three (3) Heating Elements per fluid side rated at 1,250, 1,500, or 1750 watts, each
giving the Proportioner a total heat output of 7,500, 9,000, or 10,500 watts and the
necessary control and safety components for their precise operation. The Material
Heater design allows for a controlled and precise temperature differential (ΔT) and
material application temperatures of up to 190º F under ambient temperatures.
Hose Heating System
The system is designed with a 3 KVA Isolation Transformer that enables effective
heating of up to a total hose length of 310 feet (also available with a 2KVA transformer
and a 5 KVA transformer for maximum hose lengths of 210 and 410, respectively). 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 Opposed Piston Metering Pumps
The opposed double acting Pump Line is driven by a double ended 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.
