2. SAFETY AND HANDLING
2 SAFETY AND HANDLING
This chapter contains important information on the safety, handling, and use of your
PHD Series Proportioner.
Before installing the PHD Series Proportioner and
start-up, carefully read all the technical and safety doc-
umentation included in this manual. Pay special atten-
tion to the information in order to know and understand
the operation and the conditions of use of the PHD Se-
ries Proportioner. All of the information is aimed at
improving user safety and avoiding possible breakdowns
from the incorrect use of the PHD Series Proportioner.
WARNING! Symbol is presented in front of information to
alert of a situation that might cause serious injuries if the instruc-
tions are not followed.
CAUTION! Symbol is presented in front of information that
indicates how to avoid damage to the proportioner or how to avoid
a situation that could cause issues.
NOTE! Symbol is presented in front of relevant information
of a procedure being carried out.
Careful study of this manual will enable the operator to know the characteristics of
the PHD Series Proportioner and the operating procedures. By following the instructions
and recommendations contained herein, you will reduce the potential risk of accidents in the
installation, use, and maintenance of the PHD Series Proportioner. You will provide a better
opportunity for greater output, incident-free operation for a longer time, and the possibility
of detecting and resolving problems quickly and simply.
Keep this Operations Manual for future consultation of useful information at all
times. If you lose this manual, ask for a new copy from your PMC Service Center or go on
line at our web site (www.polymacusa.com).
The PHD Series Proportioner has been designed and built for the application of
polyurea chemical systems, polyurethane foam chemical systems, and some two-component
epoxy systems

2. SAFETY AND HANDLING
WARNING! The design and configuration of the PHD Series
Proportioner does not allow its use in potentially explosive atmo-
spheres or the pressure and temperature limits described in the
technical specifications of this manual to be exceeded.
Always use liquids and solvents that are compatible with the unit. If in doubt,
consult your authorized PMC distributor.
When working with the PHD Series Proportioner, it is recommended that the opera-
tor wear suitable clothing and elements of personal protection, including, without limitation,
gloves, protective goggles, safety footwear and face masks. Use breathing equipment when
working with the PHD Series Proportioner in enclosed spaces or in areas with insufficient
ventilation. The introduction and follow-up of safety measures must not be limited to those
described in this manual. Before starting up the PHD Series Proportioner, a comprehensive
analysis must be made of the risks derived from the products to be dispensed, the type of
application, and the working environment.
To prevent possible injury caused by incorrect handling of the
raw materials and solvents used in the process, carefully read
the Material Safety Data Sheet (SDS) provided by your supplier.
Deal with the waste caused according to current regulations.
To avoid damage caused by the impact of pressurized fluids, do
not open any connection or perform maintenance work on com-
ponents subject to pressure until the pressure has been completely
eliminated.
Use suitable protection when operating, maintaining or being
present in the area where the equipment is functioning. This in-
cludes, but is not limited to, the use of protective goggles, gloves,
shoes and safety clothing and breathing equipment.
The equipment includes components that reach high temperatures
and can cause burns. Hot parts of the equipment must not be
handled or touched until they have cooled completely.
To prevent serious injury through crushing or amputation, do
not work with the equipment without the safety guards installed
on the moving parts. Make sure that all the safety guards are
correctly reinstalled at the end of the repair or maintenance work
of the equipment.

3. CHARACTERISTICS
3 CHARACTERISTICS
The PHD 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.
3.1 PRINCIPAL HEATING SYSTEM
The Proportioner consists of one (1) Material Heater without internal seals. The
Low Pressure 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. The High Pressure Heater has four (4) Heating Elements per fluid side rated at 1750
watts, each giving the Proportioner a total heat output of 14,000 watts. Every heating
system provides the necessary control and safety components for their precise operation.
The Material Heater design allows for a controlled and precise temperature differential (∆T)
and material application temperatures of up to 190oF under ambient temperatures.
3.2 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.

3. CHARACTERISTICS
3.3 DOUBLE ACTING OPPOSED PISTON METERING PUMPS
The opposed double acting Pump-Line is driven by a double ended Hydraulic Cylin-
der. The in-line pump system with opposed piston pumps provides a constant volume and
guarantees uniform pressures in both directions of pump movement.
3.4 PRESSURE BALANCE CONTROL SYSTEM
The Pressure Balance Control (PBC) system performs an automatic shutdown when
a chemical imbalance occurs. When the system is turned off, the Proportioner will perform
as if there is no PBC system and will continue pumping material. When the system is
turned on, it will continually monitor the pressure between the two chemicals (known as the
pressure differential). If the pressure differential becomes equal to or greater than the
maximum allowable pressure differential, the pumps will be shut off.
The Pressure Balance Control system can be simplified into a logic box diagram
with inputs and outputs. There are five inputs: the power supply from the main console, the
pressure readings from each chemical, the maximum pressure, and the maximum allowable
pressure differential. Inside the logic box, the actual pressure differential of the chemicals is
compared to the maximum allowable pressure differential. Depending on the circumstances
of all five inputs, there are only two possible outputs: either the pumps will continue to
pressurize and move material, or the pumps will shut off and flow will be lost.
