The DC fan units play a pivotal role in the BTS environment control system, primarily engaged in cooling operations when the mains fail or the air conditioner malfunctions. When there is a significant temperature differential between indoor and outdoor settings, the ventilation system steps in to provide efficient cooling, enhancing energy savings and prolonging the lifespan of the air conditioner.
The TF2 series of DC ventilation systems represent a cutting-edge solution, characterized by substantial ventilation capacity, reliable operation, easy installation, and an aesthetically pleasing design. This system can be managed through the HW15 model thermostat or other environmental surveillance controllers.
DC fan units is an important part of BTS environment control system, it's usually used in cooling when mains fail, or air-conditioner has fault. When the temp. difference between indoor temp. and outdoor temp. is big, using ventilation system to cool to save energy and last the use life of air-conditioner.
TF2 series of DC ventilation system is a new product, has characters as ventilation capability big, work reliable, install easy, beautiful appearance. It can be controlled by HW15 model thermostat or other environment surveillance controller.
1. Enhanced structural design for smooth airflow and high efficiency.
2. Installs from the inside, providing excellent anti-theft features.
3. Employs a DC 24V motor to drive an eccentric wheel, ensuring the damper opens and closes completely to avoid unexpected locks.
4. The filter is easily changeable and washable, facilitating maintenance.
5. Manual fan start functionality.
6. Over-travel limit switch for precise damper position detection.
7. Fans can be divided into two groups, operating alternately or together based on indoor temperature (optional special function).
8. Optional feature to detect fan work frequency, with alarm output for fan failures.
9. Optional alarm output for fan or damper malfunctions.
