TA-COMPACT-DP
For small pressure independent circuits
The TA-COMPACT-DP is the ideal solution for zone control of small circuits, enables setting of max. flow and prevent control valves from too high differential pressure. TA-COMPACT-DP combines 5 functions: differential pressure control, balancing, control, diagnostics and shut-off.
Features and Benefits
5 in 1 concept reduces costs
The installation of a valve with 5 functions reduces the investment and the installation time.
Saves energy and money
Balanced and pressure independent circuits protects systems against over flows and too high energy consumption.
Zone control
Time controlled circuits can save up to 20% energy.
Noise protection
Differential pressure control protects control valves from too high differential pressure.
Applications
Heating and cooling systems.

Differential pressure (ΔH)
400 kPa = 4 bar
Min. differential pressure (ΔHmin):
DN 10: 20 kPa = 0,20 bar
DN 15: 18 kPa = 0,18 bar
DN 20: 21 kPa = 0,21 bar
DN 25: 25 kPa = 0,25 bar
(Valid for the most demanding settings. Other settings will require a lower ΔH. Check with graphs under "Sizing" or software HySelect.)
ΔHmax = The maximum allowed pressure drop over the circuit, to fulfill all stated performances.
ΔHmin = The minimum needed pressure drop over the circuit, for proper differential pressure control.,
