The DC fan units are an indispensable component of the BTS environment control system. They are typically employed for cooling when the mains power fails or when the air-conditioner malfunctions. Utilizing a ventilation system, particularly when there's a significant temperature difference between the indoor and outdoor environments, can help save energy and extend the lifespan of your air-conditioning units.
The TF2 series of DC ventilation systems is a cutting-edge product characterized by substantial ventilation capacity, reliable performance, easy installation, and an attractive design. It can be managed using 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.
