The new low height twin vertical coil ACB20 (2-way)
active chilled beam avoids all the concerns with using
inferior inclined coil beams, without exceeding a height
of 286mm. The new ACB20 utilizes DADANCO’s unique
nozzle and unit fluid dynamics technology.
This patented technology provides very high air
entrainment ratios at low pressure drops and provides
the major benefit of superior performance delivered at
the lowest noise levels.
Typical Performance Data
Primary airflow
8 to 80 L/s @ Static pressure range of 50 - 175 Pa
Secondary Chilled Water
0.03 - 0.15 L/s
Performance Range
500 - 2,000 W
Typical Product Data
Length - 600 to 3000mm.
Width - Typically to suit T-Bars at 600mm centers, with fat and
tegular edge border styles as standard.
Appearance - Traditional perforated face.
Discharge - 2 way.
Coil - Vertical 2 or 4 pipe option with drip trays and sweat
or NPT fittings.
Primary air connection - Side or top entry as standard.
DADANCO Active Chilled Beams have been tested both
in-house and independently at ETL Laboratories.

ACB20 units icorporate 2 secondary water heat exchangers. Secondary heat exchangers must be field connected in a parallelarrangement with control and balancing valves as specified in themechanical specification for the project.
Connection must be parallel to ensure secondary air coolingperformance as specified will be delivered by each unit.
Do not connect secondary heat exchangers in series. Secondarycooling performance will be adversely affected if system designentering secondary water is not delivered equally to both heatexchangers.
