Frequently Asked Questions.
1. How does the Pro Pac-3 operate?
In a typical operation, additive supply pressure (125-150 psig typical) is provided to the inlet ball valve of
the ProPAC3 injector, via a positive displacement additive pump located on or near the additive storage
tank. The injection cycle begins when the ProPAC3 microprocessor energizes the normally closed two-way
solenoid control valve, thereby, allowing additive flow to enter the injector through the inlet ball valve. The
solenoid is energized when the programmed number of product pulses has been accumulated. The flow of
additive passes through the stainless steel filter, prior to entering the ProPAC3 flow meter. The flow of
additive through the flow meter results in generation of a DC pulse train from the flow meter to the ProPac3
microprocessor, via a Hall Effect sensor. This low voltage pulse train represents the volume of additive
being injected into the product stream. The additive exits the flow meter through ½ inch stainless steel
tubing, where it flows through the two-way solenoid control valve, prior to exiting the injector through the
check valve. When the volume of additive through the flow meter equals the programmed volume for each
injection batch, the microprocessor terminates power to the solenoid control valve, thereby, terminating the
flow of additive through the injector. The ProPac3 microprocessor totals the additive injected, totals the
product treated and is in the stand-by mode, awaiting the next injection batch request.
2. What is the power requirement for Pro Pac-3 injector?
120 VAC 60 Hz or 230 VAC 50 Hz.
3. What type of product pulse signals can a Pro Pac-3 accept?
Both AC and DC signals.
4. Would I be able to use Titan injector if I do not have product pulses?
Yes. You can use Auto PAC.
5. What is the difference between Pro Pac-3, Auto Pac, and MAI?
ProPAC3 is a proportional injection controller. It will inject proportional to the product pulses received.
For instance the injector will inject 60 cc of additive for every 40 gallon of product. In its simplest form,
the ProPAC3 requires only AC power, a product flow pulse, and pressurized additive to operate.
Auto Pac is an automatic timed injection batch controller. It is designed for situations where a product
pulse signal is not available to pace the injection process. The Auto Pac injects based on a user-
programmed time between injections and an optional maximum load volume.
MAI (Multi-Additive Injector) is a proportional injection controller. It is specifically designed to
sequentially batch inject up to eight additives at petroleum product terminals.
6. Are there any alarm features to ensure the additive/product ratio?
There are 12 alarms. Three of them are non-programmable alarms and the rest are programmable alarms.
See Alarm Section for detail.
7. Can I do on-site calibration?
Yes. As a matter of fact, the Pro Pac-3 has a feature called Auto Calibration. Once the feature is enabled,
you just need to follow the instructions displayed and the injector calibration will be done in seconds.
8. How can I configure the Pro Pac-3 injector?
There are 3 ways you can configure the Pro Pac-3 injector: internal pad buttons, Infrared Remote.
9. What is operating temperature?
Low temperature (with heater pad on) is –40 ° F
High temperature (with heater pad off) is +132 ° F
