Mô tả sản phẩm

Belimo Damper Actuators are engineered to provide precise and dependable control of air dampers in heating, ventilation, and air conditioning (HVAC) systems. Designed for direct mounting on standard damper shafts, they simplify installation while delivering reliable airflow control for commercial, industrial, and institutional buildings.

Belimo offers one of the industry's most comprehensive actuator portfolios, with torque ratings ranging from 22 in-lb to 270 in-lb (2 Nm to 30 Nm), enabling engineers to select the most appropriate actuator for virtually any air damper application.

All spring return models incorporate Belimo's MFT (Multi-Function Technology), allowing flexible configuration to suit a wide variety of building automation systems and control strategies. The integrated MFT platform enables one actuator to support multiple applications while simplifying commissioning and maintenance.

The mechanical spring return mechanism automatically returns the actuator to its predetermined fail-safe position whenever power is interrupted, providing reliable protection for ventilation and life safety systems. This fail-safe operation is particularly important for smoke control, fire protection, and critical HVAC applications.

Belimo actuators are designed with a slide-on shaft coupling, allowing quick and simple installation on standard damper shafts without additional mounting accessories. Their low power consumption improves overall system efficiency while reducing transformer capacity requirements.

The actuators maintain their rated minimum torque regardless of voltage fluctuations or ambient temperature, ensuring consistent damper operation and reliable long-term performance under varying operating conditions.

Belimo actuators are widely used for air dampers, airflow control, VAV terminal units, fan coil units, air handling units (AHUs), ventilation systems, and building automation systems. They can also serve as replacement actuators for many existing HVAC systems, including applications originally equipped with other actuator brands, provided the correct actuator specification is selected.

Manufactured in Switzerland, Belimo products are recognized worldwide for their precision engineering, exceptional reliability, and long service life. PGTECH is the official distributor of genuine Belimo products in Vietnam, providing complete HVAC control solutions and professional technical support.
