Flexible, temperature-sensitive polymer tubing designed for easy routing in tight corners. It autonomously responds to heat by rupturing at the hottest spot, forming a nozzle-shaped opening that directs flow precisely where needed. The system operates independently of electricity and also serves as a multi-sensor, enhancing its versatility and efficiency. These systems are ideal where traditional suppression is less effective, offering fast detection and response, protecting electrical panels by detecting fires at the source and avoiding extensive damage and unnecessary repair costs.
