Technical data

AB-PM Rack set is preassembled automatic
balancing solution for manifolds. The rack set is
installed in front of manifold in either radiator or
oor heating systems.

Benefits:

Automatic manifold balancing solution
*Reliable heating system

-Proper heat distribution even at partial load

-Filter to remove dirt before manifold
*Faster and simple installation
*Prepared for heat meter installation

Application

Application

AB-PM rack set should be mounted in front of manifold with AB-PM in the ow direction.
The mounting bracket to be screwed onto back plate or wall.

AB-PM is designed to be used in heating systems in residential applications. It can be used both in radiator
or oor heating systems.
AB-PM provides proper balance even at partial loads and limitation of maximal ow is simple and fast.
In addition, programmable zone control (night setback or holiday mode) is available by using On/O
actuator (TWA-Z /ABN A5), connected to a room controller (TP5001M / TPOne).
The AB-PM Rack set is prepared for heat meter installations in return ow and temperature probe
connection.

Example

Given:

Design flow through radiators loop:
420 l/h

Pressure drop trough the loop at
design flow: 10 kPa

Solution:

AB-PM DN 20 is selected. Set to 70
% (= 420/600), AB-PM will control
differential pressure of 10 kPa when
design flow is achieved. It will at any
loads including keep it under 22 kPa
at zero load, while limiting the flow to
radiator system to 420 l/h
