Electrothermal actuator for on/off regulation in radiant heating systems, normally closed 24V EMOtec 1827-00.500

Electrothermal actuator for underfloor heating control – precision and reliability in every circuit. This electrothermal actuator, designed for underfloor heating installations, is a key element in on/off control systems. Its operation based on a normally closed (NC) contact ensures safe and efficient operation. The device is ideal for both installers looking for a reliable component and end-users who value comfort and precise temperature control.

Construction and application – from comfort to savings

The EMOtec 24V actuator is a compact device with dimensions of 44.5 x 58 mm, designed for mounting on valves with an M30 x 1.5 connection. Its universal supply voltage (24 V AC/DC) makes it compatible with most control systems. A cable length of 1 meter simplifies installation, and the IP43 protection rating guarantees resistance to moisture and dust – important in conditions typical of heating installations. This actuator is primarily used in underfloor, wall and ceiling heating systems, where precise temperature control is crucial for user comfort and energy efficiency.

Key features and benefits – why choose this actuator?

• Normally closed contact (NC): Ensures safe operation – the valve remains closed in the event of a power failure. This is important from the point of view of installation safety and minimizing the risk of failure.
• Compact dimensions: Facilitate installation even in tight spaces, which is particularly important during the modernization of existing installations.
• Universal supply voltage (24 V AC/DC): Increases installation flexibility and allows integration with various control systems.
• Durable construction: Ensures long-lasting and trouble-free operation, minimizing costs associated with service and replacement.
• Stroke length 3.5 mm: Allows precise control of heat flow, which translates into optimal thermal comfort and energy savings.
• Ambient temperature -5…50°C: A wide range of operating temperatures allows the actuator to be used in various environmental conditions.
• Rated power 3 VA and max. electrical power consumption 90 VA: Means low power consumption during device operation.
• Cycle time 180 s: Specifies the time required to fully open or close the valve – ensures smooth and efficient temperature regulation.

By choosing this actuator, you are investing in a reliable solution that will provide thermal comfort in your home or building and allow you to optimize the operating costs of your heating system. It is a product worth recommending to both professional installers and demanding end-users.
