Controller Selection Information
- Choosing a Controller
There are many considerations that go into designing a building, and all of these decisions cost time and money.
So how can choosing the right Fire Pump Controller help you?
The very first choice you should consider is whether or not your building is suitable for Variable Speed. If you
make this decision early in the building process, you can save yourself tens of thousands of dollars in labor and testing, and many man-weeks of
design time compared to the normal building process.
How can this be? With Variable Speed Controllers, your engineers can design the building at rated flow and
not have to worry about being overpressure at no flow situations. This also means eliminating the hassle of PRVs, drain risers,
and possibly storage tanks and even rezoning the building to have fewer zones!
However, if Variable Speed is not a fit for your job the next choice that should be made is whether to get an EC or MC Series Controller (or DEC / DMC Diesel Controller respectively). If you are looking not only to
get the highest quality controller on the market, but to save money over time, the EC Series Controller
is a wise investment.
With a 5 year comprehensive warranty, $5,000 lightning guarantee, and expected life of 20-30 years the EC Controller
maximizes safety and durability. To read more about the unique features of an EC Controller,
That is the question, and luckily there is a fairly simple answer: if you have a generator set, or plan on being
able to access two separate sources of power, then a transfer switch is necessary. A transfer switch enables your controller
to transfer power from one source to another in case during an emergency one source fails.
Each different type of reduced voltage starting has a unique and specific reason to be used, although some
are capable of doing the same job much better than others. We highly recommend the following:
- Primary Reactor:
We also offer part winding, wye-delta, and autotransformer reduced current and voltage controllers but each of these has
their limitations. Contact Master for more details.
The proper time to use Across the Line Controllers (MCA or MCAT) is when the inrush current does not matter. In other words,
your power source does not care about inrush current, and so drawing 600% current at starting is no issue.
On the other hand, if you are using a generator, chances are you will NOT want to use Across the Line because
of the extra load you put on it.
