The Caleffi Z111900 High Current Actuator is a 24V part which is used to control the operations of HVAC systems especially in controlling heating and cooling systems. Externally it operates through valves and, in this way, there is a constant, accurate control of fluids such as water in any systems like hydronic heating, cooling circuits, as well as the radiant floor system. The actuator is fast, robust and provides better performance at high currents as compared to other similar actuators. This is suitable for connection with diverse HVAC equipment, increasing the performance of the system, energy conservation, and offering optimal temperature.
