Pump Curves – DPW Units

The DPW units include a pump assembly that is used to provide the flow through

the unit heat exchangers, and has a nominal flow of heating water for external

piping arrangements.

This pump is not designed to be the system pump providing flow to radiant loops

or baseboard.

Therefore Quietside insists on using a Primary – Secondary pumping

arrangement, the recommended method uses the traditional large diameter

Primary loop

The main circulation pump or the zone pumps will then provide circulation into

the zones or the heating system

The only exception to this Primary – Secondary rule is for Air Handling units with

a hot water coil where the Air Handling unit is located less than 10ft from the

DPW unit.
