The PH-40 Proportioner from PMC is designed and built for the spray polyurethane foam and polyurea industry. Not to mention some specific two-component epoxy systems.
Primary Heating System
The machine is designed with two independent Primary Heaters with no internal seals. Used for presetting manufacturers temperature product recommendations Each Heater has Six Heating Elements known in the industry as (fire rods) rated at 1,250 watts each with (1,500 watts optional) giving the PH-40 machine a total heat of 15,000 watts or (18,000 watts optional) and the necessary control and safety components for their precise operation.
The Primary Heater design allows a temperature differential (ΔT) of 90º F and material application temperatures of up to 190º F under normal ambient temperatures.
The PH-40 hydraulic machine is designed with a 5Kw Transformer that enables effective heating of up to a total hose length of 410 feet. The heated hose system includes an innovative design in which a continuous braid tinned copper jacket is distributed evenly around the radius 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 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 displacement and guarantees uniform pressures in both directions of pump movement. Different sized pumps options allow for various volumetric ratios to be achieved (1:4 to 1:1 to 4:1) between the chemical components used in the process.
PMC’s stroke counter allows the user to track the gallons of product being used. Combine this
feature with the expected product yield fine tuning estimating and production cost.
