BELIMO TF230-S

The BELIMO TF230-S actuator is engineered for real-world HVAC and building automation challenges. In installations where dampers must reliably default to a safe position — such as fire- or smoke-control dampers, hygiene dampers or ventilation systems — this actuator provides both motor drive and spring-return fail-safe in one compact package. When power is lost, the spring mechanism drives the damper to its safe position (closing or opening, depending on configuration), mitigating safety risk. The integrated auxiliary switch simplifies monitoring by signalling damper position or limit status directly to your building automation system. It suits damper cross-sections up to approximately 0.5 m², and accommodates the common shaft size range via its universal clamp. Compared to basic actuators without spring return or position feedback, the TF230-S offers enhanced safety and control — ideal for your systems in home automation, parking ventilation or fire-service automation via your MSI Agency. Installation is straightforward: mount directly on the shaft, secure anti-rotation clip, select direction (L/R) and you’re ready. Low power draw, minimal maintenance requirements and built-in safety functions make it a superior choice for demanding regulatory and performance conditions.
