Danfoss TWA-Q Thermal Actuator | 230V AC | Normally Closed (NC) | 1.2m Cable

Product Description:

The Danfoss TWA-Q is a compact and efficient thermal actuator widely used for automated flow control in heating and cooling applications. Operating on a standard 230V AC supply, this model is designed as Normally Closed (NC), meaning it remains closed when power is off, providing a critical fail-safe function for building systems. With a 5.00 mm stroke, it is perfectly optimized for use with Danfoss AB-QM valves in fan coil units (FCUs) and chilled beam systems throughout the UAE. Its robust design and 1.2-meter pre-installed cable make it an easy-to-install solution for achieving high energy efficiency and superior indoor comfort in modern Dubai commercial and residential developments.

Key Features & Benefits:

• Normally Closed Operation: Ensures the valve remains closed in case of power loss, preventing unnecessary cooling or heating.
• Seamless Valve Integration: Specifically engineered to fit Danfoss AB-QM valves for precise flow regulation.
• Visual Position Indicator: Features a clear indicator on top to show whether the valve is open or closed, simplifying maintenance in the UAE.
• Quiet and Reliable: Thermal operation ensures silent movement, ideal for hotel rooms and offices.
• Fast Installation: Compact size and pre-wired cable allow for quick commissioning by HVAC technicians.

FAQs:

• Q: Can I use this actuator with any valve?
• A: It is primarily designed for use with Danfoss AB-QM (DN 10-32) valves. Always check the connection thread compatibility.
• Q: What is the “Normally Closed” benefit?
• A: In the UAE, if a power failure occurs, the NC function prevents chilled water from flowing, which helps in preventing condensation and energy waste.
• Q: Is it difficult to replace an old TWA-Q?
• A: No, it features a simple screw-on ring that allows for easy replacement without needing special tools or draining the system.
