Belimo TFRB24 Actuator

The Belimo TFRB24 is a spring return damper actuator engineered for reliable on/off control in HVAC systems. Providing 22 in-lb torque, this actuator is designed for small to medium-sized dampers where fail-safe operation is required during a power loss. Operating on a universal 24VAC/DC power supply, it features brushless DC motor technology, which ensures precise control and reduces power consumption. As a direct replacement for TFRX24 models, it offers a seamless mechanical fit for existing installations, minimizing labor time for contractors. The rugged NEMA 2 housing provides durability in demanding environments, while the mechanical spring return guarantees a positive seal every time power is interrupted. This HVAC actuator is a staple for professional technicians requiring a dependable replacement for Belimo TFRB24 or older X-series customizable models, ensuring consistent airflow control and system integrity.

• Fail-Safe Protection: Reliable mechanical spring return ensures dampers return to a safe position during power interruptions.
• Direct Retrofit: Engineered as the standard direct replacement for TFRX24, simplifying field swaps for technicians.
• High Efficiency: Brushless DC motor eliminates the need for limit switches and reduces electrical load.
• Versatile Power: Compatible with both 24V phase-cut or DC signals for flexible integration into various control loops.
• Compact Footprint: Narrow design allows for installation in tight mechanical spaces and plenum applications.

Is the TFRB24 compatible with older TFRX base models?
Yes, the TFRB24 is designed as the direct technical successor to the TFRX24 series, maintaining the same mounting footprint and wiring requirements.

Can this actuator be mounted in any orientation?
The unit is versatile for mounting, but standard practice dictates avoiding positions where moisture can accumulate in the conduit or motor housing.

Does this unit require adjustment for end-of-rotation?
No, the Belimo TFRB24 is electronically protected against overload and does not require limit switches; it stops automatically at the end of its stroke.
