2. The free cooling system is, using mostly in service and technology sectors; for internal air cooling. It is an energy-saving and environmentally-friendly product. The free cooling system, throws away the warm air to outside of the system room; instead of cooling it by air-conditioner. As a support of existing air-conditioning systems; The free-cooling system provides significant energy savings. By this way, it pays itself, in a very short time.

3. Electricity bills, one of the key costs of the enterprise. The system pays for itself by energy-saving, its investment costs for a very short time. The free-cooling system, in the fall, winter and spring, provides maximum savings. In addition to reducing the use of air-conditioning system with ozone friendly to nature, does not contain gas.

4. Indoor and outdoor temperature is constantly monitored. When internal ambient temperature reaches a certain value, the fan starts running. The fan throws out the warm air from inside of the system room to outside, and gets the cool air inside. Thus, the free circulation of cool air is provided. When the internal temperature of the environment reaches the desired value, Fan will be stopped. Fan does not run when the air conditioner operates till getting the internal environment to the desired level. The air conditioner stops when the temperature is reached.

9. Max. Power = 0.125kWh Example: A Base Station Power Consumption for Cooling Max. Power = 2kWh For the winter time, A/C power consumption: 12 hours x 2000 W = 24kWh Power consumption of FCS120C/D: 24 hours x 125 W = 3 Kwh Power consumption of FCS190C/D: 24 hours X 197 W = 4,8 Kwh Saving 19~21 Kwh per day

10. During a 20-day study; Fan (FCS55D: 55 W fan) 380 hours, Air-Conditioner 19 hours worked. Example Graphic 1 A/C Fan

11. Easy to install, plug and play. The interior is laid out excess heat, filtered fresh air is taken in.. Low power consumption, max. 125W. – 197 W. Suited for Commercial and living buildings; with quiet operation. Manages all the hardware from a single control panel. Emergency cooling system operates with a power supply 24V or 48V; when the site down; in order to the cooling continues. Advantages of the System
