Termoställdon

TWA

TWA är ett litet ställdon för elektrisk på/av-styrning, utformat för att manövrera olika typer av ventiler och golvvärmegrenrör.
TWA-serien omfattar ställdon för 24 V (SELV*) eller 230 V matning, tillgängliga i både normalt stängda (NC) och normalt öppna (NO) versioner (ventillägen utan matningsspänning till ställdonet).
NC/S-versioner med ändlägesbrytare finns också tillgängliga för vissa ställdonstyper.
Varje ställdon är utrustat med en visuell positionsindikator som visar om ventilen är öppen eller stängd.
TWA kan anslutas till RA-, RAVL- och RAV-ventiler från Danfoss. TWA-K-versionen (M30×1,5) kan anslutas till Heimeier-, MNG- och Oventrop-ventiler.
Andra ventiler måste verifieras individuellt för att säkerställa korrekta ventilstängningsdimensioner och ventilens toppgeometri.

*SELV = Säkerhet extra låg spänning

Thermot

The Thermot is a small actuator for electrical on/off control, designed to operate M30 x 1.5 valves and floor heating manifolds.
The Thermot range includes actuators for 24 V (SELV*) or 230 V supply, available in both normally closed (NC) and normally open (NO) versions (valve positions with no supply voltage to the actuator).
Each actuator is equipped with a visual position indicator to show whether the valve is open or closed.
The Thermot (M30×1.5) can be connected to Heimeier, MNG, and Oventrop valves.
Other valves must be verified individually to ensure correct valve closing dimensions and valve top geometry.

*SELV = Safety Extra Low Voltage

ABRA-A5

The ABRA-A5 ON/OFF zone valve actuator has been specifically designed for use with Danfoss RA2000, RA-C, and RA15/6 series of valves used for heating and cooling applications. Additional base adapters are offered for the potential use of the ABRA-A5 to other non-Danfoss valve bodies.

ABN-FBH

The ABN-FBH actuator is a thermal wax actuator (TWA) for opening and closing valves on heating circuit manifolds in underfloor heating systems. The actuator has been specially developed for targeted use in the widest variety of systems. Its compact size, design, functionality and flexibility are the most impressive features. A valve adapter concept guarantees the perfect adjustment of the actuator to almost any valve bases and heating circuit manifolds on the market.
The ABN-FBH actuator serves to ensure the optimum control of valves on heating circuit manifolds. Control can be implemented using ON/OFF switching or by applying pulse‑width modulation (PWM).
The ABN-FBH range includes actuators for 24 V (SELV*) (*SELV = Safety Extra Low Voltage) or 230 V supply.

Actuator ABNM A5 LOG/LIN

The ABNM A5 0-10V thermal actuator has beenspecifically designed for use with AB-QM valvesDN10-32/½-1¾ inch in heating and coolingapplications.

​​​​​​​Control is done by a 0-10 V signal, which is provided either by a room thermostat or, in most cases, by a central direct digital control(DDC) system. The actuator converts the 0-10 V signal into a proportional actuator travel, which logarithmic / equal percentage (ABNM A5 LOG).For fan coil unit or chilled ceiling application choice of logarithmic version is recommended (water to air heat exchanger). The result will belinear system response and thus optimal room temperature control.
