Thermal actuators for ventilation lines
Air distribution lines are made of different mechanical parts, including elements with flaps, for air or smoke flow regulation, as well as for security reasons.
The regular flaps are manual
… or motorized
DELTA CONCEPT fabricates and sells thermal probes for motorized flaps control
Spiral shaped bimetal: The thermal sensor turns with a linear deflection (constant angular degree, per °C of temperature variation).
Cantilever shaped bimetal: The thermal sensor pushes an arm in a bi-stable translation mouvement (snap action and reset at 2 different temperatures, on specification).
Advantages of the bimétal technology:
- Can be used both as thermal sensor and actuator
- Simple and low cost
- Electrical energy free
- Reliable and sustainable
