Typical setup for clean in place
Condenser in and out piping is factory equipped with a
3/4-inch female NPT. Remove the plug that comes from
the factory and install fittings as shown in this typical
setup. It is recommended to install supply and return
water valves.

to determine
the amount of Goodway Scalebreak-MP
needed and length of cleaning time. The
information in the calculation tool allows
you to adjust the amount of ScaleBreak-MP
needed based on the thickness of scale in
your SWEP BPHE. For more information

1. Isolate the heat exchanger from the system by
closing the supply and return water valves.
2. Position a ball valve on the low point of the heat
exchanger. This valve will function as the entry
point for your ScaleBreak-MP cleaning and can be
closed to prevent backflow if needed.
3. Attach your circulation hoses so you are pumping
into the bottom of the heat exchanger and returning
the fluid out the top.
4. Your exit point on top needs to be at the highest
point of the exchanger. If the exit point is lower
than the top of the plate pack, position the hose at a
higher point. This action will insure the entire plate
pack is flooded and ScaleBreak-MP comes in
contact with all the interior wetted surfaces. It will
also insure upper interior areas do not become air
bound with CO
2
or foaming resulting from the
cleaning.
5. Fill your exchanger with water and perform a
hydrostatic test by turning your pump on and
circulating the water. This action assures the
exchanger is isolated and none of the ScaleBreak-
MP will be needlessly lost.
6. You will need to bleed off enough water equal to
the volume of ScaleBreak-MP required for the
cleaning. If you relieve too much water, you can
add some back to complete your circulation loop.
7. Water formed deposits will occupy volume, as a
result, additional water may need to be added
during the cleaning process as deposits are
dissolved.
8. Periodically check your isolation valves as they may
have initially seated against scale. As ScaleBreak-
MP dissolves the scale, this action will help you
avoid losing product.
9. Circulate the ScaleBreak-MP solution for the
recommended timeframe as indicated by our
calculation tool.
10. During your ScaleBreak-MP cleaning you will want
to make sure your solution remains active. For this
step, please follow our “Testing ScaleBreak’s
Effectiveness” procedure.
