Core Componenets
1.Scroll Compressor
The core power of the unit is from Copeland hermetic scroll compressor that guarantees the high efficiency, low noise and the long life of the unit. 
2.Heater
An electric heater with perfect overheat protection function and ionization resistance, able to meet environmental requirements of the small heat-load machine rooms for base stations in cold arctic-alpine area.
3.Indoor fan
A blow fan adopts direct drive centrifugal fan with backward curved blades, the range of static pressure can be adjusted from 0 to 400pa, realizing the continuous operation of 365 days* 24 hours, 10 years’ average life.
4.Humidifier
An internationally advanced electrode steam humidification system under which the amount of humidification and water inflow and outflow are all controlled by computer, the auto cleaning program for the humidifier cylinder ensure normal humidification efficiency of the cylinder.
5.Filter
Air filter which is EU4 standard which is metallic bracket filtering the dust and particulate effectively by air circulation, then purifying the air environment of telecom room.
6. Evaporator
An efficient evaporator made from quality material with advanced professional technology and featuring large heat exchange area and the realization of higher sensible heat factor of precision air conditioning unit.
7. High quality Controller
It strictly complies with CE and IEC standards and is empowered with advanced electric control technology and able to work under a power source of 380V±20%. In addition, it is installed with a power supply protection module, enabling it to make a selection of protective value in a range of 380V±50%. When voltage goes beyond the selected range, it will automatically protect the unit. While the voltage becomes normal, it will automatically restart the unit.
8. Expansion Valve
Expansion valve adopts advanced thermal expansion valves with strong reliability and stability and can precisely control the supply of refrigerant. In order to achieve the reduction of energy consumption for refrigeration equipment, we employ advanced electronic expansion valves in high-performance precision air conditioning units to realize less energy consumption.
Condenser
With an enclosure of anti-corrosion alloy that ensures service life and appearance of the is elaborately designed and able to satisfy the environmental protection requirements on noise, and a fan speed regulator that controls the rotating speed under different temperature and ensures sound operating effect and energy saving.
